Setup
overview
- if possible, with the source unit off, confirm that the primary volume control is turned down (counter clockwise).
- Turn on the source unit (CD, or MP3 player). Re-confirm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or “0”
- djustment. Make sure that the green LED on the end of the amplifier is illuminated.
- Play a clean musical selection of which you are very familiar. CD is preferred.
- Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.
- Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion. Increase the amplifier gain (clockwise) until distortion is heard, then back the level
- down (counter clockwise) until the distortion is eliminated. Smal adjustments may need to be made to balance the levels of mutiple amplifiers.
REM TURN ON / DC SENSE ON SWITCH
There are two methods of switching the amplifier on and off. Select the
appropriate position suited for your application.
REM TURN ON
This will turn on the amplifier when a +12v switched power typically from a
source unit, is connected to the Amp Turn on – BLUE wire on the main power
connection harness.
DC SENSE
The DC SENSE is for use with the source units that do not offer RCA outputs.
