5. ADJUSTMENTS
Input Mode
■
If you control the EBP1000A via an aftermarket head unit, or Moniceiver naviceiver with RCA line
out and use remote signal, set the INPUT LEVEL switch to “Lo”.
■
If you control the EBP1000A an OE CD radio, OE navigation use, which does not have RCA output
and remote administration, set the INPUT LEVEL to “Hi”.
Auto Turn On Modus
The setting of “REM” which uses the +12 V switching voltage of an aftermarket head unit, the most
reliable method is this active subwoofer on and off. If the amplifier module via the high-level in (ie
Lautsprecherabgriff) is to be controlled, additional modes are present, through which the internal
amplifier can be controlled.
Input Sensitivity
For best sound quality and dynamics, correct input sensitivity adjustment of the amp module is
mandatory. The input gain is responsible for signal to noise ratio and the maximum distortion free
bass output of the active subwoofer.
ATTENTION:
Before you start any adjustment on the amp module, set all tone controls of your
headunit to their neutral or flat position, e.g. BASS, TREBLE and Loudness as well as User EQ presets.
Set the X-OVER potentiometer to 12 o’clock (for approx. 120 Hz lowpass frequency).
Set the GAIN in the anti-clockwise position. Turn up the volume of your headunit to about 50% of
max. output. Slowly increase the GAIN potentiometer setting by turning the knob clockwise, until
you hear a balanced sound with sufficient bass.
Lowpass Frequency
Finally, you can fine tune the lowpass cut-off frequency on the amp module. To fine adjust the upper
bass reproduction of your subwoofer, turn the X-OVER potentiometer out of its 12 o’clock position.
clock or anti-clock wise.
Phase
Now check both slide switch positions of the PHASE control. Compare the bass reproduction on the
drivers seat resulting from each position of the switch. One setting, i.e. either 0° or 180° will give you
more bass, a better (more precise) bass or even both. This is the correct setting that shall be kept.
