DSP Overview
- Input gain adjustment: With this adjustment in the MAXIMUM position, the DSP accepts signals of up to 2V RMS at the input. (Normal sensitivity). With the gain adjustment at MINIMUM, it is possible to apply signals from up to 9V RMS, without distorting the input. (Minimum sensitivity).
- RCA input signal: Input for low-level/high-impedance signals (RCA).
- WIRED input signal: Input for high-level/low-impedance signals (from the speaker output of multimedia centers or head unit).
It has the function of turn on through the input signal, therefore it does not need to use the REMOTE IN wire of the power connector when using this input.
Note: The system was designed for use in practically all head units and multimedia centers on the market. However, in some head units, the turn-on function may not be obtained due to the type of audio output circuit. In this case, use turn on through the REMOTE wire normally. Input clip LED indicator: Indicates that the signal is reaching the maximum limit of the processor input, which causes signal distortion. If this indicator lights up, reduce the processor input gain or adjust the level into the source. - Limiter/clip LEDs indicators: Has dual functions: Indicate that the signal from the output has reached the maximum level (when the limiter is off) or that the limiter has activated (when the signal reaches the threshold set on the limiter). Power connector: See page 12.
Screens & basic operation
INITIAL SETUP: When turned on for the first time, the processor waits for the language to be set. Choose the desired language and confirm with a short press on the encoder.
Turning the encoder knob (clockwise or counterclockwise), adjusts the master volume (Input volume).
Output selection keys
Short press (click) on the key of each output(1 to 8) It performs an adjustment of the individual gain in each output.
- General mute: Short press the mute all/ memory key to mute all outputs simultaneously. Press again to reactivate.
- Individual mute: Long press the output key (1 to 8) until its light goes off. To exit individual mute, long press it again.
Short press on the center of the encoder, to access the MAIN MENU and its functions. Long press on the center oft he encoder returns to the previous menu on. 
Use the encoder, turning it left (decrease) or right (increase). Menu selection, options or parameter changes can be made by pressing the center of the encoder.
Note: On any of the audio adjustment screens, short pressing the output keys (1 to 8) allows you to check and adjust the parameters of each channel without leaving the desired menu.
Tip: To fine-tune a parameter or increase/decrease the number after the decimal point, turn the encoder slowly. For example, when adjusting the signal level (dB), the increase will be 0.1 dB when turning the encoder slowly, and 1 dB when turning it continuously and fast.
The PRO 2.85 is factory configured in STANDARD mode. To access the DYNAMIC PEAK setting, go to the MAIN MENU on the last option “Mode Selection”.
Long press the encoder to return to the main screen.
- Audio menu: Adjusts and controls related to audio processing:
I/0 Routing: Set the internal connections between outputs and inputs. Available options: A, B or A+B (sum of thetwo inputs). E.g.: setting the OUT 1 output to A, its signal will only come from input A.
- Input graphic equalizer: It has 15 equalization bands, with attenuation/gain of up to 12 dB, at the central frequencies defined in the ISO standard (25 to 16 KHz, 2/3 octave).
- Only available in ac s sImu aneous y on an Inputs.
- The Pro 2.85 has 12 predefined equalizations, selectable in MAIN MENU> EQ Presets.
- Only available in standard mode
- Only available in standard mode
- Input parametric equalizer: Equalizer with adjustable parameters, acts simultaneously on inputs A and B.
- G = Filter gain/attenuation (-12dBto +12dB)
- F = Central filter actuation frequency, adjustable from lOHz to 22KHz
- Q = Filter width adjustment, from 0.4 (widest) to 10.0 (narrowest)
- 1 band in Standard mode sbandson DYNAMIC PEAK
- 1 band in Standard mode sbandson DYNAMIC PEAK
- Crossover: Sets the high-pass (HPF) and low-pass (LPF) filters to be applied to the output paths. The cutoff frequencies are adjustable from 1 0Hz to 22KHz and are available in Butterworth, Linkwitz Rilley filter types in different attenuations (-6, -12, -18, -24, -30, -36, -42 and -48dB octave).
Delay: Set t he delay to be applied to audio signal, for systems alignment. The position of transducer’s voice coil should be taken in account in order to set the optimal delay value.
Rotate the rotary encoder to set the delay amount to be applied. The voice coils of each transducers isn’t aligned inside the acoustic box, so there is some delay that can degrade the perfect audio playing. The Delay feature apply different delay amount for each output way, in order to get the perfect audio alignment.
How to set the delay parameter value (centimeter)
- Set the reference coil(*) farthest from the box panel (in our example, the reference was the center of the horn coil)
- Measure the other channels and find the measure 6) . Set the closest measurement (in cm) for each channel.
- Repeat the procedure for the other channels (the channel selection can be done through the keys of each channel).
Phase: Allows inverting the phase of the channel output signal, selecting option [180]. Select the channel using the OUTl to OUTS selection keys and select the desired phase by turning the encoder.
- Limiter: Sets the limiter, which acts as a limiter for the maximum signal level of the processor output,soas notto exceed the power limit defined for each channel.
Modes: MAN = Manual Attack and Release adjustment; AUT: Sets the Attack and Release parameters automatically, according to the channel’s cutoff frequency (HPF).
Limiter parameters:
- T= Threshold- Point at which the limiter begins to act (indicated by the RED LED on each channel turning on). To turn the limiter off, turn the encoder clockwise until [OFF] appears in the threshold value.
- A= Attack-Time that the limiter waits before reducing the gain after the signal exceeds the th res hold.
- R = Release-Time thatthe limiter takes to return to the original gain after the signal drops below the threshold.
PEAK limiter (only in DYNAMIC PEAK mode)
- Limiter: Acts as a limiter for the maximum signal level of the processor output, so as not to exceed the power limit supported for each system transducer.
Limiter in RMS function:
- Limiter that acts with reference to the RMS value of the audio signal, prevents overheating of the speakers due to excessive power.
- According toThreshold selected.The accuracy ofthis measurement depends on the signal frequency as a function ofth the Attack time. At low frequencies, very fast attack times can affect measurement accu racy.
Limiter parameters:
- Modes: MANUAL = Manual Attack, Hold and Release adjustment; AUTO: Sets the Attack, Hold and Release parameters automatically, according to the channel frequencycutoff (HPF).
- Threshold– Point when the limiter begins to act (indicated by the RED LED on each lane turning on). To turn off the limiter, turn the encoder clockwise until [OFF] appears in the threshold value.
- Attack, or Attack time -Time needed to limiter reduce the gain after the signal reaches the threshold.
- Hold -Time that the limiter keeps the signal attenuated even after its level drops below the threshold.
- Release, or Release time – Time needed to limiter return to the original gain after the signal drops below the threshold.
Limiter in peak function (DYNAMIC PEAK mode only)
Limiter that acts with reference to the PEAK value of the audio signal, prevents mechanical damage and overheating of the speakers due to excessive displacement.
Limiter parameters:
- Modes: MANUAL = Manual Release adjustment; AUTO: Sets the Release parameter automatically, according to the channel frequency cutoff (H PF). Dynamic- Point when the limiter acts (indicated by the lighting of the RED LED on each channel) with reference to the peak value of the signal in relation to the threshold defined in the RMS limiter (Music Dynamics).
Hold – Time that the limiter keeps the signal attenuated even after its level drops below the threshold (Dynamic).
Release, or Release ti me -Ti me needed to for the Ii miter to return to the origi na I gain after the signal drops below the threshold.

- Output parameter EQ.: 1-band equalizer with adjustable parameters for:
- G = Filter gain/attenuation (-12dB to+ 12dB)
- F = Filter actuation center frequency, adjustable from 1 0Hz to 22KHz
- Q = Filter width adjustment, from 0.4 (widest) to 10.0 (narrowest)
- Output Cloning: Allows you to use the parameters of another channel, creating a “clone” of an already configured output.
Audio Generator: Sine wave generator, with frequency and variable amplitude. With 4 modes:- Fixed Frequency: Sine generator with frequency (1 0Hz to 22KHz) and amplitude (-60dB to 0dB) adjustments. Note that when activating the generator, the signal is sent to all outputs and it is possible to adjust the other functions and parameters in real-time, as the generator remains active and defined as a signal source when in the ON position, even when accessing another function.
- The voltage level shown is informative and may differ depending on the processing settings (Equalization, crossover, limiter, etc. .. ).
- Sweep (Slow/ Medium/ Fast): It performs a signal sweep, with the initial and final frequency defined by the user, which remains in a continuous cycle (repeating) until the generator is turned OFF. There are 3 sweep speeds avaliable.
