GAIN ADJUSTMENT
Equipment required
Ø
Voltmeter capable of measuring AC
voltage;
Ø
Media with 60Hz sinusoidal signal
recorded at 0Db
Adjustment Procedure
Ø
This procedure is the same for both gain
controls;
Ø
Set the gain control to minimum;
Ø
Disconnect the speakers from the
amplifier output;
Ø
Turn off or set to "0" all audio processing
(bass, treble, loudness, EQ, etc.);
Set the volume of the main unit to
approximately 3/4 of the total.total.
Ø
Set the audio positioning controls in the
center (fader and left and right controls);
Ø
Set the crossover to "F";
Ø
Play 60Hz media on the main unit
Ø
Measure, with the aid of a voltmeter, the
output voltage of the amplifier at the
terminals where the speakers were
connected;
Ø
Turn the gain control clockwise until the
voltage observed in the table below is
reached;
Ø
After adjustment, turn off the main unit
and reconnect the speakers.
