Gain Control - The gain control matches the input sensitivity of the amplifier to the source unit being used. The
operating range varies from 100mv to 6V.
Adjusting the gain
1. Turn the gain control on the amplifier all the way down (counter clockwise).
2. Turn up the volume control on the source unit to approximately 3⁄4 of maximum.
3. Adjust the gain control on the amplifier until audible distortion occurs.
4. Adjust the gain control down until audible distortion disappears.
5. The amplifier is now calibrated to the output of the source unit.
Warning : Never adjust the gain control without a subwoofer connected.

Low Pass X-Over Frequency Control - Used to select the desired LP x-over frequency. The frequency is adjustable
from 40Hz to 200Hz.
Subsonic Frequency Control - Used to select the desired subsonic frequency (high pass). The frequency can be
adjusted from 20Hz to 50Hz. The subsonic filter protects subwoofer(s) against low frequencies that can cause
damage. Very useful with vented enclosures.
Phase switch - Used to match the bass from subwoofers and front speakers. Toggle the phase switch from 0° to
180°. Keep the loudest bass response. Also useful in bridge mode.
Power On LED - The LED illuminates red when the amp is switched on. For Short or Thermal protection, see
