This is a critical step to insure your amplifier
is properly adjusted to match the signal
output level of your source unit.
THIS IS NOTA VOLUME CONTROL! . .
MIN MAX
1. If possible, with the source unit off , confirm thatthe primary volume control is
turned down (counter clockwise).
2. Turn on the source unit (CD, or MP3 player). Re-confirm thatthe volume is
turned down. Make sure the source unit controls; balance, fader, bass and
treble are all set to center or "O " adjustment. Make sure thatthe green LED on
the end of the amplifier is illuminated.
3. 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.
4. Stop increasing the source unit volume when you reach 3/4 (about 75%) or until
you hearspeakers begin to slightly start producing distortion.
5. Increase the amplifier gain (clockwise) until distortion is heard, then back
the level down (counterclockwise) until the distortion is eliminated. Small
adjustments may need to be made to balancethe levels of multiple amplifiers.
