This is a critical step to insure your amplifier
is properly adjusted to match the signal
output level of your source unit.
Level Setting
THIS IS NOT A VOLUME CONTROL!
1. If possible, with the source unit off, confirm that the primary volume control is
turned down (counter clockwise).
2. Turn on the source unit (CD, or MP3 player). Re-confirm that the volume
turned down. Make sure the source unit controls; balance, fader, bass and
treble are all set to center or "0" adjustment. Make sure that the green
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
of the source unit up.
4.
Stop increasing the source unit volume when you reach 3/4 (about 75%) or
until you hear speakers begin to slightly start producing distortion.
5. Increase the amplifier level (clockwise) until distortion is heard, then back
the level down (counter clockwise) until the distortion is eliminated. Small
adjustments may need to be made to balance the levels of multiple amplifiers.
