When the potentiometer is at the 
minimum position, the amplifi er goes into 
Mute mode. On the SPA4-60 amplifi er, the 
remote level controls for channel 1 & 2 are 
independent from channels 3 & 4 remote 
level control. 
On the SPA4-60 model, closing the 
"Standby Switch" between the fi rst two 
pins of either Ch1-Ch2 or Ch3-Ch4 causes 
all four channels to go into Standby.
