BIT GLOSSARY

Virtuoso 3.0 MAC technology provides the ability to perform auto equalization correction based on the signal amplitude using an RTA measurement and a selected target curve without using bit Tune.

Audison proprietary technology that allow pure digital signal transfer from source to amplifier with a resolution up to 24 bit/96 kHz.

USS technology allows Virtuoso 3.0 to work with head-units featuring the "speaker load detection" circuit.

bit Drive technology allow the communication with Audison bit Tune and bit Drive portal.

Automatic De-equalization algorithm to "flatten" any equalization applied by default by OEM sources.

Analog Device SHARCTM series chip with floating point precision, to reach the highest audio quality.
Virtuoso 3.0 FIR mode operation allows the user to process up to 9 digital channels with crossover FIR filters and equalizer. This sound processing mode, much more demanding in terms of calculation resources, ensures a leading edge in-car listening experience.

Automatic De-time algorithm to compensate time-delayed factory outputs prior to signal summing.
Automatic De-phase algorithm to compensate the overall system phase restoring original signal, even in case of OEM sound enhancement algorithms.
High level inputs polarity check and automatic correction in case of inversion

According to the definition of Hi-Res audio provided by JAS (Japan Audio Society - jas-audio.or.jp), Virtuoso 3.0 meets 24 bit / 96 kHz native processing requirement.

Virtuoso 3.0 I/O routing approach dedicated to OEM sound system (hi-level), based on "pass-through" the existing OEM infotainment's output channels.

Virtuoso 3.0 RVA (Remote Volume Aux) provides the ability to select an auxiliary source (I.e.: a Hi-Res audio player or auxiliary wireless interface connected by digital inputs) and adjust its volume via the OEM Head Unit, offering full support to the management of the car priority signals while music is played through the auxiliary source.
Virtuoso 3.0 features a built-in RTA with target curve support (display, creation, importing) and correction file support. It can use your USB mic or USB sound card, or the bit Tune (but bit Tune is not required). Mic correction files can be imported.

Virtuoso 3.0 I/O routing approach based on signal summing, signal reconditioning & flattening. With this setup mode, automatic algorithm options named DE-EQ / DE-Phase, DE-TA, Polarity check and Auto Input Switch can be selected.
Virtuoso 3.0 Parametric EQ mode allows users to control both amplitude, center frequency and bandwidth for each of 11 poles available. Parametric EQ poles are capable of making precise adjustments to sound and are commonly used in sound recording and live sound reinforcement.

Virtuoso 3.0 MPC technology provides the ability to deliver precision tuned systems for one or two seats (overall), correcting phase and amplitude, automatically. MPC is powered by Percept® algorithm, developed specifically for mobile, that use FIR filter computation performed by Virtuoso 3.0 SHARC DSP chip, and the bit Tune - upgraded to 3.0 level - to measure the impulse response of the system in the vehicle cabin.

Virtuoso 3.0 Graphic EQ mode allow user to adjust amplitude for each of the 31 bands (1/3-octave equalizer) available using a slide control to boost or cut frequency components passed by that filter.
Virtuoso 3.0 signal-driven option to Dynamic EQ allow equalization curve to be controlled by OEM volume control position, rather than only by DRC volume knob.

7.2.3 PASS THROUGH
The selection of I/O configuration using the "PASS THROUGH" allows the interface in direct configuration between inputs and outputs. Moreover, during the guided procedure it allows to divide the emission front in order to increase the number of existing ways per front. The peculiarity of this configuration is that it does not provide any equalization, correction of time delays, phase variations and channel sums, allowing subsequently only to intervene on time and phase alignment equalization for the Master input. When using the other auxiliary inputs (AUX, Optical 1/2) it is also possible to separate the Master setup by creating one that performs better than the limits set by the OEM system.
Remark: if the Master configuration features Rear Surround channels, during the selection of the auxiliary inputs these will not be available. The procedure must be performed by selecting which memory to assign the Master Pass-Through input from the start.

By default the switching time is set to 13.33 (default value) but it can be set starting with a minimum of 13.33 ms up to a maximum of 6800 ms (6.8 sec). Should any undesired switching occur from AUX to Master, the release time can be increased to eliminate it. If the switching from AUX to Master is too slow, the release time can be decreased to speed it up.
I. Threshold: function to set the auxiliary input signal minimum threshold previously selected, to activate it. The operation levels range from 0 dB to -96 dB.
L. OEM Volume to Selected Auxiliary Input: select the flag to adjust the audio system volume using the volume control on the Head Unit. The volume control from DRC is disabled when an auxiliary input of the bit One HD Virtuoso is activated through the "Auto Input Switch" function.
M. OEM Fader/Balance to Selected Auxiliary Input: select the flag to automatically adjust the audio system balance and fader through the OEM source, when an auxiliary input is enabled (see point B).
N. WIRED MODE: By default it is set to 16.5 KHz, but it can be varied depending on the Head Unit performance, from a minimum of 14KHz to a maximum of 22KHz. This frequency can not be heard since it is concealed by the processor, and it has the function to control the Master volume and the selection of the bit One HD Virtuoso auxiliary input. If malfunctions occur using RVA with the Analog AUX input of the Head Unit, choose the lowest available value, so that a good functional compromise is reached.
O. USB DONGLE MODE: When using a USB RVA device (supplied), this contains by default the tone "16500 hz -6dB", as set in the "Freq Tone" window. If malfunctions occur during the switching, proceed as suggested below:
1) Playback of audio files on the Auxiliary input (AUX / Optical) of the bit One HD Virtuoso does not reach maximum level:
- Disconnect the USB RVA device from the source and insert it into a PC. Unzip the folder (.rar format) called "RVA 16.5KHz" in the desktop of your PC, and then copy the decompressed file "16.5 KHz -6dB", in the main route of the USB RVA device.
2) During the switching between Master input and Auxiliary input (AUX / Optical), annoying hisses can be heard: - Disconnect the USB RVA device from the source and insert it into a PC. Unzip the folder (.rar format) called
"RVA 16.5KHz" in the desktop of your PC, and then copy the decompressed file "16.5 KHz -6dB", in the main route of the USB RVA device. If the problem still persists when re-inserting the USB RVA device in the USB reader of the Head Unit, copy the previously unzipped file "16500 hz -12dB" inside the USB RVA device.
- If the instructions in the previous point do not have the desired effect, proceed as follows: Disconnect the USB RVA device from the source and insert it into a PC. Unzip the folder (.rar format) called "RVA 16.5KHz" in the desktop of your PC, and then copy the decompressed file "16.5 KHz -6dB", in the main route of the USB RVA device. Select the value "18000" in the "Freq Tone" window of the PC software. Car head units do not behave in the same way and it may be necessary to choose other tone values in order to achieve the optimal setting. If an optimal control tone is reached to use the RVA function, further refinement can be carried out by acting on the input sensitivity of the Master source, varying the levels of all the input channels via the link function, within a permitted limit of ± 3dB with respect to the calibration (see section 8.11).
Remark: if a USB reader is not available, you can copy the tone to be used for automatic switching from the supplied USB RVA device to an SD Card type storage device. Please note that the storage device must contain only this file and no other files. The different types of tracks are available and downloadable from the Audison website (www.audison.eu), in the download section of the product bit One HD Virtuoso.
P. Level Tone: function to set the "Freq Tone" for the switch of the bit One HD Virtuoso auxiliary input. The Level Tone default value is set to a value calculated during the I/O Configuration Wizard. It is possible to select among 0 dB to -96 dB intervention levels, to optimize any spurious commutations compared to the automated calculation provided by the I/O Configuration Wizard.
Remark: this function is only active when the RVA function is used via the Head Unit Aux analog input.
Q. RVA Frequency Settings: function to select the switching tone of the bit One HD Virtuoso auxiliary input (AUX / OPTICAL 1 / OPTICAL 2), by connecting with the Head Unit AUX analog input or the USB multimedia device.

· StartUp Time: delay between the device startup and the output audio turn on. Each amplifier, when starting up, has its own delay before becoming operative. By setting the Startup Time to a value equal to or higher than the longest of these delays a synchronized startup of the audio of the entire system can be achieved.
· Shutdown time: delay between the turn off/deactivation of the REMOTE OUT signal to the amplifiers and the bit One HD Virtuoso shutdown. Acting on this parameter is not generally essential but it could useful to decrease it when amplifiers in the system produce a "Bump" while shutting down. 11. Power PC Mode: if this function is enabled, it does not allow the bit One HD Virtuoso to be switched off, if the audio system is accidentally switched off, or if it is automatically disabled by the car during calibration. This function will allow you to keep the changes made enabled and possibly save them, or switch the main system back on and continue with the setup.

Pressing the MEMORY button on the main menu you can access the different functions you can perform on the featured presets.
The following functions are available:
- Load All Presets: it loads all the memories (A/B/C/D/E/F/G/H) from a file previously saved (.prs format);
- Save All Presets: it saves all the memories (A/B/C/D/E/F/G/H) in a file that can be recalled (.prs format);
- Load Current Preset: it loads a memory previously saved (.pro format) by placing it on the memory you are operating on;
- Save Current Preset: it saves the memory you are operating on in a file that can be recalled (.pro format);
- Copy Preset From: it provides the ability to copy the content of one memory into another memory;
- Current Preset Default: it restores the crossover and equalization default values, that would be suggested at the end of the set up procedure;
- Enable Memory Overall: it enables the Overall function which recalls a memory previously saved (see following point), optimized for a perfect listening from all positions within the car compartment. This function can be activated through the terminal, setting the Overall Sel cable to +12V (see section 8.3.4);
- Select Memory Overall: it sets an existing memory as "Overall". Choose one of the memories where an Overall setup is set.
The following data will be stored into the presets:
- the filter settings for each channel; - the time delay settings for each channel; - the equalization settings for each output channel; - the Main EQ settings (see section 8.9.2); - the Dynamic EQ settings/activation (see section 8.12.3); - the Bass Boost settings/activation (see section 8.12.4); - the output levels of each channel; - listening points markers.
We recommend that you copy the parameters entered in the preset you are using into the presets that are not being used. The presets can be recalled through the DRC MP. If some presets are not stored, they will store the default settings.
Pass through In Pass through mode there is only one memory, assigned in the "I / O configuration Wizard" phase, to the Master input. So when the Master input is selected will be available only one memory, and it will not be possible to copy other memories on it. The remaining memories and related functions will be available at the input change.

8.7 FILTER SETTINGS / DELAY 6
The bit One HD Virtuoso manages 13 crossovers, one for each output channel. Each filter allows the setting of the parameters related to the channel highlighted on the Channel Map The filters can be adjusted in normal or extended mode through an active POP UP for a more detailed adjustment, activating it using the button.

Remark: by activating the PASS THROUGH mode the Filter Settings menu will not be active.

8.7.1 FILTER SETTINGS
By clicking on the icon , the menu for the output channels filter settings will appear as per image to the side.
1. Xover L/R Link: when activated, the modifications applied to one of the channels (right or left) will automatically be applied also to the other one. To activate it click on the blue flashing light.

2. Invert Phase: it provides the ability to

invert the phase of the channel under

examination by 180°. It can be activated

by selecting the green flashing light.

This function can be useful to solve

alignment problems among the different filtered channels

3. Filter Type: it enables the selection of the different types of filters that can be assigned to the channels. Full Range Low Pass High Pass Band Pass
WARNING: in this case pay utmost attention to the filter adjustment. Speakers have mechanical limits which must not be exceeded and could lead to damage to the components.

4. Filter Model: it enables the selection of the applicable type of filter Butterworth (IIR) Linkwitz (IIR) Bessel (IIR) FIR (to be enabled during the Wizard see sec. 7.2.2)
When starting the software, the bit One HD Virtuoso offers the Butterworth as a standard filter model. By changing the model to Linkwitz or Bessel, the change will be made only to the channel (mono) or channels (stereo - Xover Link activated) concerned.
If a FIR type system configuration was set up, the PC software will not allow to manage other types of filters. If you wish to switch to the Butterworth / Linkwitz or Bessel, (IIR) filters, proceed by converting the configuration file as suggested in sec. 8.2.1.

USER'S MANUAL

Difference between IIR and FIR filters.

IIR digital filters faithfully simulate analog filters (active or passive), approximating phase and frequency behavior. Like their analog equivalents, they are affected by unavoidable phase rotations at the cut-off frequency, which are different based on the type of curve used (Butterworth, Linkwitz, Bessel), however still perceived when listening. In practice, for instance, a fourth-order low-
pass IIR filter (24 dB / Oct) at 200 Hz cut-off, plus a high-pass symmetric filter, results in a phase rotation ranging from 0 to -360 degrees along the whole audio spectrum. This phase alteration affects the perception of the sound image, which highlights inaccuracies in terms of coherence and stability.

vs IIR FILTER

Think of a 3-way system where the door-mounted

18 cm woofer is 400 Hz crossed with the

middle-range, installed on the a-pillar next to

a tweeter, itself crossed with the middle-range

at 5.000 Hz, using crossovers with IIR filters.

The system phase alteration reduces the focus of the instruments on the virtual stage. For this reason, a number of audio enthusiasts prefer to adopt 2-way systems with a woofer

Electric frequency response simulation (module and phase) of a low-pass Linkwitz-Riley fourth order crossover (24 dB/ott.) summed with a symmetrical high-pass featuring a 200 Hz cut-off frequency. FIR filters (in blue) and IIR filters (in black).

and tweeter crossing at 2.500 Hz with a slope

of 6 dB / Oct, so as to limit phase rotations as much as possible. This solution, however, presents a number of

significant disadvantages, mainly due to increased distortion and lower tweeter power. With a slope of only 6

dB / Oct., the music signal around the cut-off frequency is simultaneously generated by tweeters and woofers

to a considerable extent. Since a tweeter and a woofer have very different electro-acoustic parameters,

the sum of the two emissions does not produce clear output signals, which results in less clarity in the

reproduction of musical transients.

Improved acoustic quality with the use of crossover filters and FIR equalizers. The use of FIR filters guarantees an important result: the phase behaviour is linear, free from rotations or indecisions. This also makes the use of filters with a very high slope (up to 48 dB / Oct) possible, without altering the phase response. Such a high slope for the filter enables the midrange and tweeters mounted on the a-pillar to work at lower frequencies without any issues with power handling, thus raising the emission front.
Therefore thanks to the FIR filters the advantages of three or multiple-way systems are completely exploited taking in-car listening experience to a different level. When listening, a system that uses FIR filters provides great clarity in transients reproduction, such as the acoustic piano hammer strikes or the drums. The stereophonic
image is deeper and definite. Instruments in the virtual stage are more focused and seem to have more space between them. Even the intervention of any equalizer over the frequency response, when available in FIR technology, does not modify the audio signal phase, allowing more precise and detailed corrections without conditioning the audio quality.

When starting up the software, the bit One HD Virtuoso offers

Butterworth with 12 dB/oct slope as default slope. By changing the

slope, the change will be applied only to the channel you are working on.

Eg.: if you are adjusting the Front Woofer, the change will affect only that channel (right and left, if linked). If you selected Band Pass as filter type, the slope will be applied to both hi-pass and low-pass. With the Band Pass filter type the filter slopes can be unbound.

USER'S MANUAL

8.7.2 SET DISTANCE AND DELAY Two modes are available for the set up of the bit One HD's time delays:
- Basic Mode. The system time delays can be displayed by selecting the Channel Map loudspeaker from the main software screen. Then enter the distances (cm/inch) from the listening point, and the related "fine set" (ms).

Fig.1
- Extended Pop Up Mode, by selecting the icon the extended menu for the set up of time delays will appear. This operating mode, as well as allowing a faster and easier data entry, will provide different views of the time delays according to the listening point, the farthest speaker, depending on the distance (cm/inch) or time (ms).
Fig.2
Preliminary remarks Sound moves through the air at a speed of 343 mt/sec (1.125 ft/sec) and at the temperature of 20°C (68°F). If you know the distance from the sound emission point, you can then calculate the time sound takes to get to the listener's ear. By default the bit One HD enables the entry/automatic calculation of time delays by entering the simple measurements between the listening point and the speakers by selecting the option "From Listening Point cm/inch". It is however possible to enter the same time delays with respect to the listening point by entering the time value (ms-milliseconds), selecting the option "From Listening Point ms". If instead of the distance from the emission point only the distance between the loudspeakers with respect to the farthest emission point is available, it is possible, by selecting the option "From Farthest Speaker cm/inch, once the farthest speaker is selected, to enter distances from the other speakers, and then fine-tune the remaining speakers of the system. However, it is possible to enter the same time delays with respect to the farthest speaker by entering the time value (ms-milliseconds), selecting the option "From Farthest Speakers ms". Switching between the 4 time delay entry modes is automatic, the software will automatically convert the values displayed on the Channel Map.
FINE SET AND PHASE DELAY. The delay assignment according to the distance calculation is theoretical. That is, small variations need to be applied due to small errors in distance measurement, due to the resonance inside the car compartment and, mainly, due to the speaker phase problem. Two speakers reproducing two areas of frequency one close to the other (ex. Woofer and Midrange), in their crossing area will simultaneously reproduce, at attenuated level, the same frequencies. Due to the different nature of the speakers, they will show a difference in phase that, for a short frequency interval, works like a time delay. By acting on the "fine set" you can partly also correct problems of Phase Delay. By acting on the "fine set" you can change the automatically set time delay. The delay that is varied adds up to (+ x.xx) or is deducted from (- x.xx) the value of the delay shown in the "Delay / default" window, which does not change the assigned value which is the one automatically assigned. Assigning a positive value ( + x.xx) with the "fine delay" means increasing the delay of that speaker and therefore moving it away from the listening point. Likewise, assigning a negative value (- x.xx) means decreasing the speaker's delay and therefore moving it closer to the listening point. If you try and give a negative value to the farthest speaker, an alert message will be displayed. By acting on "fine set", the word "fds" will light up on the corresponding channel of the "Channel Map", to inform the user about the entry on the highlighted channels.

- From Farthest Speaker ms: the delay introduced between the farthest speaker and the rest of the system. If a fine set is entered, the value on the channel map will become red.
- The software, in addition to offering the conversion of values according to the selected mode, will allow their adjustment, passing from one mode to another.
WARNING: if, once you have set the distances according to the "driver" listening point you click on the "passenger" listening point, the bit One HD will not re-calculate the delays according to the new reference point because the buttons available in the SELECT A CHANNEL diagram are merely descriptive and their only purpose is to remind you that you have set the delays for that listening point!
8.7.2.3 TIME DELAY SETTING PASS-THROUGH MODE. In the case of the Pass-Through mode with selection of the Master input, it is also possible to manage time delays. It must be specified that if the bit One HD is interfaced to a source with time delays, it is advisable to intervene by acting only on the Fine Set. Once the time alignment procedure has been completed, it will be possible to intervene on the output equalizer (MASTER), to optimize the response of the system according to the level alignment at the various frequencies. For the auxiliary inputs Optical 1/2 and Aux instead it is possible to act on the time delays setup, as described in the previous paragraphs, since these inputs are not connected to the Master input.
8.8 EQ SETTINGS 8 The bit One HD Virtuoso software provides a series of Parametric / Paragrafic equalizers to be managed on screen which, with extreme versatility, provide for an optimal calibration of the audio system. The user can operate on the equalization of the Master or AUX analog inputs by choosing the "Input EQ" option, on the single output channels equalization by selecting the "Channels EQ" option and operate on the whole system equalization by choosing the "Main EQ" option. Thanks to the active Pop Up menu it is possible to intervene in a more precise and accurate way on all the available intervention points, working full-screen on the equalizers using all the control commands.

8.8.2 CHANNELS AND FRONT EQUALIZER

The CHANNEL EQ equalizer works for functional groups and for each channel according to the selection chosen for the display. It is possible to perform an equalization by selecting a single speaker in the system or selecting the entire front of the audio system.

Difference between IIR and FIR filters Similarly to crossover filters (see sec 8.7.1), graphic and parametric equalizers based on IIR filters alter the signal phase behaviour with significant effects on audio quality. A heavily equalized signal is characterized by an unclear stereo image and
lack of transients definition. Audiophiles often classify this feeling as a veil that blurs the musical message and deprives it of the necessary emotion.

definite. Instruments in the virtual stage are more focused and seem to have more space between them. Even the

intervention of any equalizer over the frequency response, when available in FIR technology, does not modify the

audio signal phase, allowing more precise and detailed corrections without conditioning the audio quality.

The equalizer works for functional groups and therefore we will have: - an equalizer for the Front Left Channel; - an equalizer for the Front Right Channel; - an equalizer for the Rear Left Channel; - an equalizer for the Rear Right Channel; - an equalizer for the Center; - an equalizer for the Subwoofer.

The software is able to manage both an IIR and FIR configuration chosen during the "I / O Configuration Wizard" phase, and the equalizer setup varies depending on the choice made.

8.8.4 RTA
By enabling the equalizer pop up menu, the three main equalizers are available, as well as the RTA tool, which allows the user to quickly tune the audio system. The acquisition takes place via an audio interface connected to the PC, and a microphone to it.
In Channel EQ mode it is possible to perform a self-calibration of the front with respect to the target curves.
Description:
A) Settings. It allows the user to select the audio device available, connected to the PC.
Driver: it allows the user to select the audio capture devices connected to the PC.
Remark: it is possible to interface the Audison bit Tune device to the PC, which can manage both the HSM microphone and the TMD microphone. The TMD microphone compared to the HSM microphone allows greater accuracy in the measurement, while the HSM microphone allows an environmentally more accurate measurement
Microphone Calibration File: it allows the user to load, if available, the calibration file of the microphone connected to the audio device selected in the previous point. The correct connection of the audio device to the PC is confirmed by the green logo. If the logo is red, check the audio interface settings or its correct connection to the PC.
B) Speed: it sets the updating speed of the spectral measurement displayed for a good compromise between accuracy and ease of reading.
C) Weighting: it selects the type of weighting filter for the measurement.
None: excludes any weighting filter in signal acquisition. It expresses the absolute value but does not take into account the acoustic perception of the human ear.
A-weigh: Suggested. It enables an A-type weighting filter. It inserts a filter that simulates the perception of the human ear with a low background noise. It is the curve used for the signal to noise ratio measurements (S/N Ratio).
C-weigh: it enables a C-type weighting filter. It is used with high-level background noise
D) Target: it allows the user to load an arrival curve of the final result after having acquired the environmental response of the passenger compartment. The default curve provides the ability to achieve an optimal listening ambience, which can then be manually adjusted by interacting on the front equalization with the parametric equalizer.

the "Subwoofer Level.

Important Remark: the output level adjustment (2) affects the system signal / noise ratio (whistle / background hiss). We recommend that you always set the bit One output at high level and the amplifiers' sensitivity at low level, so the amplifiers will be less sensitive to background noises/hisses. An excessive output level causes the clipping led lights to turn on (1), especially if equalizations with high gain are applied. Therefore we recommend that you proceed as follows:
a) Adjust the amplifiers sensitivity level to the minimum value (3-4V RMS). b) Balance the emission level of the system channels by moving the sliders (2) paying attention to maintain a
centered mid level at around -20 dB. Turn the output volume to an acceptable listening volume level. c) Set the desired output equalizations (see sec. 8.9). d) Insert a CD playing a highly dynamic track. e) Select the "Link" function (5), move the slider and increase the output channels level until one of the "clipping"
led lights turns on (1); move the slider back of at least 2-3 dB (check the value on one of the displays (3)). f) Increase the "Master Volume" (6) up to the maximum undistorted level taking it close to "0" dB. g) In case the signal is highly distorted with the "Master Volume" at "0" dB, the output levels (2) will need to be
decreased or enable the "Limiter" function. If, on the contrary, no distortion occurs, the amplifiers' sensitivity will have to be increased until the first distortion symptoms appear: by doing this, you will make the most of all the available power.

Remark: this procedure leads the user to calibrate the system at "zero dB undistorted". This is not always the best solution, since, if you listen to a track that has been recorded at a lower level or with lower dynamics than the track used for the setup, a loss in dynamics may occur. So a good compromise needs to be found, depending on the listener preferences.

8.12 SETUP 12

1. PERCEPT MPC: this function is enabled/disabled when a calibration 4

is performed using the bit Tune software. The equalization applied is displayed on screen and the frequency response can be adjusted

by 5 poles.

2. Master De-EQ/Phase Align.: by selecting this menu it is possible to view the progress in Module and Phase of all the Head Unit fronts (see sec. 7.2.2.7).

MODULE - Selecting the De-Eq on/off button, you can
enable or disable the de-equalization applied to the Head Unit connected to the bit One HD Virtuoso.

- Selecting the Wizard button, it is possible to carry out a new configuration session to set the sensitivity levels of the source and check whether the source is equalized or not (see sec. 7.2.2.6).

- by clicking on the "Suggested AP Filter Set" key, it is possible to Enable or disable the correction of the phase applied to the Head Unit Connected to the bit One HD Virtuoso detected during the analysis performed. The graphic interface will
show the fronts related to the All-Pass filters application (Front L-R, Rear L-R, Center), and a chart where the fronts electric result selected from the menu will be displayed. If a phase analysis was performed during the phase "Configuration Wizard" procedure (see sec. 7.2.2.7), the compensation points suggested by the
analysis will be displayed. They can be fine tuned thanks to the electric result and listening sessions. If the automatic phase analysis procedure has not been performed, the All-Pass control points will be present but no position for compensation will be recommended.

All-Pass Filter type:
There are two types of All-Pass filters, 1st and 2nd order. Their selection is done by double clicking with the mouse pointer, which will highlight the area with a different color depending on the type selected. First order filters are light blue, while second order filters are yellow. Their activation is displayed by the transition from a point to a well-highlighted intervention area that occurs by setting the phase other than 0 °.

All-Pass Filters Setting Frequency: by moving the point to adjust with the mouse pointer (f: 20 Hz ÷20KHz).

Phase:

+ and

+ allows the

change of the Phase control at 1 degree Steps.

For 1st order All-Pass the adjustment ranges

from 0-180° while for 2nd order All-Pass the

adjustment ranges from 0 -360°.

+ and

+ allows the change of the Q factor at 0.1 Steps (just for 2nd order All-Pass).

USER'S MANUAL

Total Electric Response. The chart shows the electrical sum of the channels selected in the menu "Trace Curve". If a "Phase Analysis" was performed (see sec. 7.2.2.6), two curves will be displayed. The Blue curve refers to the trend of the selected fronts, where the presence of All-Pass filters can be shown, provided by one or more holes in the frequency domain, while the orange color refers to the fronts compensation via All-Pass filters. If the Phase Analysis was not performed, only the orange curve resulting from the modifications made via All-Pass adjustment will be displayed.
Phase ON/OFF By clicking on the Phase on/off key, it is possible to enable or disable the correction of the phase applied to the Head Unit connected to the bit One HD Virtuoso. The activation is successful when the led light becomes red.
Restore Phase Alignm suggestions: If an "AUTOMATIC MASTER DE-EQ / PHASE Analysis" was performed and new valued are then edited, it will be possible to restore the phase compensation values suggested by the software (see sec. 7.2.2.7).
3. Dynamic EQ: the sound of an audio system may very according to the reproduction volume. At low volume, the noises coming from outside the vehicle and the especially insulated acoustic within the car compartment contribute to limit (especially in low frequency) the system's performance. Generally during calibration you need to consider that the adjustments performed with low level volume may change relentlessly when the volume will be increased.
The Dynamic Equalization improves the listening actively operating on the variation of the frequency response as a consequence to the volume change. The Wizard will suggest a series of windows to set up the equalization to be applied to the general frequency response. The bit One HD Virtuoso will automatically perform a gradual data interpolation, following the signal level and therefore acting according to the system volume. Two operating modes are available. To use this function click on the button to the left of the menu until the orange led lights up. To disable the function click again on the button until the orange led turns off.
Reference. The dynamic equalizer can be adjusted in two ways:
DRC VOLUME: the trend of the dynamic equalization curve depends on the Virtuoso master volume level set via DRC.
Input Signal: the trend of the dynamic equalization curve depends on the Virtuoso input level. You can choose whether to apply this curve either to the Master input or to the auxiliary inputs (Analog Aux, Optical 1/2).

USER'S MANUAL

SETUP To set up the dynamic equalizer click on the button to the right of the menu and proceed as follows:
Insert a CD in the source and play a reference track. A semi-automatic procedure will start. Move the Volume slider setting the low volume listening reference level. After adjusting the slider, select START.

Move the EQ slider to set up the low volume response equalization until the desired sound is achieved. In this case the equalization curve which applied is pre-set. When reaching the desired setting select SAVE. At this point the reference curve for low volume listening will be applied.
The semi-automatic procedure continues requesting the set up of the high volume listening reference level. Move the Volume slider to the desired level. After adjusting the slider, select START.

Move the EQ slider to set up the high volume response equalization until the desired sound is achieved. After finding the right adjustment select SAVE. At this point the reference curve for high volume listening will be applied.
Reset Dynamic EQ During the setup the Reset EQ button can be selected to reset the applied modifications and restore the default values.
To confirm the settings and activate the Dynamic Equalizer while listening click on the X of the PC software window.

At a later stage, besides being enabled and disabled via PC software, this function can also be enabled/disabled via DRC MP.
