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 gain 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 LEVEL control clockwise until the sound just begins to distort, then back off slightly to cut
distortion and operate at optimum gain.
Remember, the
level control is not a volume control.
Ignoring these three steps above may leave you with
damaged speaker and/or a damaged amplifierr.
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
Sub Sonic Adjustment
The sub sonic control will filter out all frequencies below where the control it is set from going to your
subwoofer(s). This will prevent your subs from playing any low frequencies that may harm the speaker
