GAIN SETING

Ø

Disconnect the output cables from the 

amplifier outputs;

Set up procedure

Ø

loudness, EQ, etc.);

Ø

Set  the  source  unit's  fader  control  to 
center position;

Ø

Increase the gain control until the target 
voltage is observed with the voltmeter 
(see the chart below);

Ø

Connect  the  AC  voltmeter  to  the 
speaker  output  connectors  of  the 
amplifier.  Make  sure  you  test  the 
voltage  at  the  correct  connectors  (+ 
and –);
