Make sure that the cables for power and audio signal are not on the same side of the vehicle and that they
do no cross each other; this will help reduce any noise that may radiate from the power cable and the signal
cable. If an audio cable is too close to a power cable, it may pick up the magnetic field generated by the power
cable, which could lead to a loss of quality in your signal.
Important – if you plan to use the OUTPUT jacks to feed a stereo amplifier you must connect a stereo signal
to the INPUT jacks of the amplifier.
This control allows you to match the input level of the amplifier to the output level of your head unit. Matching
the input can be accomplished in four simple steps:
1. Make sure that the remote level control is not plugged in until after the master gain control is set.
2. Set the GAIN control on the amplifier to Min (completely counter clock wise).
3. Turn on the head unit and adjust volume to 2/3 maximum, and set the BASS and TREBLE to zero.
4. Adjust the GAIN control clockwise until the sound
just begins
to distort, then back off slightly to cut
distortion and operate at optimum gain.
Remember, the
GAIN control is not a volume control
. Ignoring these steps above may leave you with dam-
aged speaker and/or a damaged amplifier.
LPF (Low Pass Filter) Adjustment
The crossover frequency adjustment filters out frequencies that you don’t want your speaker(s) to reproduce.
Using the LPF control, adjust the Low Pass Frequency to limit the amount of mid range you want going to your
woofer(s). Since musical tastes vary, adjust the crossover by ear while listening to the music of your choice.
Be sure to set the tone controls of your source unit to flat before adjusting the crossover.
