FUNCTIONAL INSTRUCTIONS

2. SOURCE

: 

•  Here you can choose between the different input sources 

SPDIF

 (optical input), 

MAIN

 (RCA audio inputs) or 

HI LEVEL

, 

AUX

 (RCA 

stereo input) and 

WiFi

 (optional).

3. CH-SETTING

: 

•  Here you select the particular output channels or output channel pairs in which you want to change the settings. 

You have the option to link the respective channel pairs for 

L

 and 

R

 with the lock symbol in the middle to synchronize the settings for 

both channels. With 

L-> R COPY

 you can also copy the setting of the currently selected left channel to the right channel.

4. CROSSOVER

: 

•  Here you can select the required filter type (

FILTER TYPE OFF

, 

HP

, 

BP

 or 

LP

)  

and set under 

FREQUENCY

 the desired cut-off frequency. The sliders only work  

when the particular filter type is activated. As soon a filter type is selected, it will be  

displayed graphically under point 8. 

Note: 

If you have selected a filter type, the cut-off frequency can also be changed  

under point 8 with the mouse. Click and hold the red dot and move the cursor to  

the desired location on the frequency band.

•  Hint: 

Instead of using the slider, you can also type in the cut-off frequency directly  

with the keyboard after a double click on the values below 

FREQUENCY

. 

Confirm by pressing 

ENTER

.

5. GAIN

: 

•  Here you can reduce the level of the individual 

Outputs A – H

 from 0dB to -40dB. With 

MUTE

 you can mute the respective channel. 

If necessary, you can use 

MUTE

 under 

MAIN

 to mute all output channels.

•  In addition, under 

MAIN

, the total output level of the DSP processor (-40dB to + 12dB) can be adjusted. 

Attention: 

Use this control with caution. Too loud level could seriously damage your speakers.

6. DELAY

: 

•  Here you can adjust the time delay and phase shift of the individual 

Outputs A – H

. For each output channel channel you can individ-

ually set the time delay of the signal under 

DELAY

. Above 

PHASE

, the unit of delay can be switched between ms (milliseconds) and 

cm (centimeters). 

Hint: 

Instead of using the slider, you can also type in the value directly with the keyboard after a double click on the values above the 

sliders. Confirm by pressing 

ENTER

. 

•  Below the sliders you can switch the phase from 0° to 180 ° individually for each channel. 
•  With these two functions you can match your sound system to the vehicle acoustics and adjust the acoustic stage perfectly.

7. HP SLOPE / LP SLOPE - CONFIGURATION OF SLOPE

: 

•  Select under 

HP/SLOPE

 the desired slope of the high-pass filter and under 

LP/SLOPE

 the slope of the low-pass filter, which is se-

lectable in 6dB steps, starting from 6 dB per octave (very flat) to 48 dB per octave (very steep). 

Note:

 The 

HP/SLOPE

 or 

LP/SLOPE

 control panel is inactive (gray), if under 

4. CROSSOVER

HP

, 

LP

 and 

BP

 is not selected.

8. FREQUENCY BAND PREVIEW

: 

•  The frequency band shows graphically the envelope of the 31-band equalizer (point 9) and the currently selected settings of the 

output channel or output channel pair from point 4.

9. 31-BAND EQUALIZER

: 

•  With the sliders below you can set the desired dB value (-18 to +12) between 20 Hz to 20000 Hz for each output channel (except 

subwoofer channels G & H: 11-band equalizer 20 Hz - 200 Hz). 

Below the individual sliders you can enter the Q (quality) as numeric value (0.5 for very shallow to 9 for very steep). 

With 

ByPass

 you can switch off the Equalizer function. 

Press the 

RESET

 button to reset all Equalizer settings to default (All other settings are not affected by this).
