Dynamic Bass

The “Bass” knob is located on the left edge of the main screen and is a very effective way to increase bass performance without overloading the speakers. Level at “0” = no Dynamic Bass function active.
Level from “1” to “20” = the higher the value, the stronger the bass boost.
Dynamic Treble

TheThe “Treble” knob is located on the left edge of the main screen and is a very effective way to increase treble performance without overloading the tweeters. Level at “0” = no Dynamic Treble function active.
Level from “1” to “20” = the higher the value, the stronger the treble boost.

CHANNEL ROUTING

In this menu, you can assign an input signal to each output channel, including the desired gain level. It is also possible to combine two or more input signals into one output channel. For better clarity, you can also name each channel.
By default, the channels are configured as follows:
CH1 – Front Left (FL) – Full Frequency (Full Frc) | Input “INCH1” Gain 0 dB
CH2 – Front Right (FR) – Full Frequency (Full Frc) | Input “INCH2” Gain 0 dB
CH3 – Rear Left (RL) – Full Frequency (Full Frc) | Input “INCH3” Gain 0 dB
CH4 – Rear Right (RR) – Full Frequency (Full Frc) | Input “INCH3” Gain 0 dB
CH5 – SUB-L – Left Sub | Input “INCH1” and “INCH3” Gain 0 dB
CH6 – SUB-R – Right Sub | Input “INCH2” and “INCH4” Gain 0 dB
Channels 7 to 9 are not assigned.
You can restore this preset at any time by selecting “Restore”.
If you want to enter your own configuration, select “Reset” to reset all settings. Each channel will then show “None”, which means that no channel assignment is present.
Configuration of Multi-Way Front Systems

Note: Please note that each channel name with Full Frc can only be used once: e.g., FL Full Frc or FR Full Frc. So, if you want to actively control a multi-way front system, select the appropriate designations:
3-Way Front System
CH1 FL – High Frc (Tweeter) | Input “INCH1” Gain 0 dB
CH3 FL – Mid Frc (Midrange) | Input “INCH1” Gain 0 dB
CH5 FL – Low Frc (Woofer) | Input “INCH1” Gain 0 dB
CH2 FR – High Frc (Tweeter) | Input “INCH2” Gain 0 dB
CH4 FR – Mid Frc (Midrange) | Input “INCH2” Gain 0 dB
CH6 FR – Low Frc (Woofer) | Input “INCH2” Gain 0 dB
For each channel, set all input channels “INCHx” not mentioned above to OFF by sliding the switch to the left.
2-Way Front System
CH1 FL – Mid-High Frc (Tweeter) | Input “INCH1” Gain 0 dB
CH3 FL – Mid-Low Frc (Tweeter) | Input “INCH1” Gain 0 dB
CH2 FR – Mid-High Frc (Woofer/Midrange) | Input “INCH2” Gain 0 dB
CH4 FR – Mid-Low Frc (Woofer/Midrange) | Input “INCH2” Gain 0 dB
For each channel, set all input channels “INCHx” not mentioned above to OFF by sliding the switch to the left.
Center Speaker
CH7 Front Center (FC) – Full Frequency (Full Frc) | Input “INCH1” and “INCH2” Gain 0 dB For each channel, set all input channels “INCHx” not mentioned above to OFF by sliding the switch to the left.
This preset also sets the corresponding crossover settings in the Crossover menu. The values are standard to protect the connected speakers during configuration and can be adjusted individually by you.
Optical Output of CH5 + CH6
Every setup you are doing for the CH5 and CH6 will also affect the optical output. So especially if you are adjusting the DSP for a 3-way front system, you should route the woofer signal to CH7 and CH8 instead of the suggested CH5 and CH6 above.
Subwoofer Configuration in BTL Mode
Output channels 5 to 8 can be bridged in pairs to provide more power for a subwoofer or woofer. In this case, select the appropriate connection cable and set the switch on the side of the device to the correct position.
BTL 8.0 – no bridging of output channels
BTL 6.1 – CH7+CH8 are bridged to a mono channel
BTL 4.2 – CH5+CH6 and CH7+CH8 are each bridged to a mono channel
BTL 4.1 – CH5+CH6+CH7+CH8 are bridged to a mono channel
Please note that in BTL mode only the main channel is configured in the Channel Routing menu:
BTL 6.1 CH7 (CH8 is not available for configuration)
BTL 4.2 CH5 and CH7 (CH6 and CH8 are not available for configuration)
BTL 4.1 CH7 (CH5, CH6, and CH8 are not available for configuration)

In this menu, you can apply a delay to the speaker signal to simulate an ideal listening position.
Here’s how to do it: Note the distance between your listening position and the individual speakers. Select the farthest speaker as the reference for the other speakers. Use the following example to calculate the values for your speakers:

Due to reflections in the vehicle interior and possibly inaccurate distance measurements, the correct values for the listening position may differ from the calculated values. Feel free to adjust the values by +/- 5 cm until you perceive a stable and accurate soundstage. If you want an absolutely precise setting, contact your Axton dealer for a professional calibration.

INPUT EQ

Depending on the source, it may be necessary to smooth the input signal to achieve a better input signal. This may be necessary for vehicles with a simple OE speaker system without separate tweeters. Some of the OE head units in these vehicles, for example, have an extremely high treble level to get more treble from the full-range speaker. You can set the input EQ for each source separately. You can adjust the input EQ for each source separately.
F0 ‒ The Center Frequency
F0 stands for the frequency you want to adjust. You can select a frequency between 20 and 20,000 Hz for each band.
Q factor
Q determines the effect of the EQ filter (bandwidth) on the frequency band around the chosen center frequency F0.
Example 1: F0 = 1000 Hz
desired bandwidth of EQ filter = 1000 Hz (i.e. 500 Hz – 1500 Hz)
Q = 1
Example 2: F0 = 1000 Hz
desired bandwidth of EQ filter = 200 Hz (i.e. 900 Hz – 1100 Hz)
Q = 5
Q factors from 0.3 to 9.9 are possible.

OUTPUT EQ

You can create your sound according to your settings in the EQ menu. Depending on the grade of required accuracy, you can adjust up to 31 bands of the parametric equalizer.
Gain
With this slider, you determine the level for the selected frequency. Values from -12 dB to +12 dB can be set. Pro tip: Generally, it is advisable to remove energy rather than add it. Frequency dips often have so-called phase cancellations as the cause. Sound waves from different speakers meet at the same frequency but different phases, reducing the overall level at that frequency. If you don’t notice any or only minimal effects when increasing the level, keep the value at 0 to avoid unnecessary stress or overload of the speakers.
F0 ‒ The Center Frequency
F0 stands for the frequency you want to adjust. You can select a frequency between 20 and 20,000 Hz for each band. Use the slider for this or press the value on the right edge of the slider. A pop-up window will appear where you can enter the exact value of the desired center frequency. Confirm with “Ok” or cancel with “Cancel”.
Q-factor
In the “Q” row, set the Q-factor or the bandwidth of the intervention. Use the slider for this or tap “-” or “+” to set the Q-factor in 0.1 steps. The Q-factor (Q) determines the effect of the EQ filter (bandwidth) on the frequency band around the chosen center frequency F0.
Example 1: F0 = 1000 Hz
desired bandwidth of EQ filter = 1000 Hz (i.e. 500 Hz – 1500 Hz)
Q = 1
Example 2: F0 = 1000 Hz
desired bandwidth of EQ filter = 200 Hz (i.e. 900 Hz – 1100 Hz)
Q = 5
Q factors from 0.3 to 9.9 are possible.
If necessary, you can choose independent equalizer settings for each channel individually or for all left and right channels together. Simply use the “Combine” button at the top right and choose whether you want to copy the values from the left channels to the right or from right to left. To reset all settings to “0”, tap the “Restore All” button at the top right corner. If you only want to try the default settings and then return to your personal settings, exit the app without saving and restart it. The app will then reload your saved settings from the amplifier. The EQ settings also apply to the corresponding preamp outputs.

CROSSOVER

InIn this menu, you can assign a frequency band to the connected speakers that corresponds to their recommended frequency range. You can choose independent crossover settings for each channel individually or for all left and right channels together. Simply use the “Combine” button at the bottom right and choose whether you want to copy the values from the left channels to the right or from right to left.
In the “HPF” row below the diagram, you can set the slope of the high-pass filter (OFF, 6 dB, 12 dB, 18 dB, and 24 dB) as well as the filter characteristic (Butterworth, Bessel, Linkwitz) and the cutoff frequency.
In the “LPF” row below the diagram, you can set the slope of the low-pass filter (OFF, 6 dB, 12 dB, 18 dB, and 24 dB) as well as the filter characteristic (Butterworth, Bessel, Linkwitz) and the cutoff frequency.
The blue line in the diagram shows the set slope of the filter. Setting the slope to “OFF” means that the signal is unfiltered and contains all frequencies.
The filter settings also apply to the corresponding preamp outputs.

GAIN PHASE MUTE

In this menu, you can make the following settings for each individual channel: volume, mute, and phase. Adjust the gain using the slider or the +/- buttons.
Tap on 0 degrees in the second-to-last column to switch between 0 degrees phase or 180 degrees phase (reversed electrical phase).
Tap on Mute to mute or unmute the channel.
The settings for Gain/Phase/Mute also apply to the corresponding preamp outputs.
