•
•
Spares jumpers, located at end of the circuit board (5 way holder)
PAU- Place in if you are using a key switch.
PEV- Place in if you are using a selector switch or facia control.
M2 1mV- Place in to make M2 input at mic level (1mV) leave out for M2 at line level (100vV) ie music etc
NOCF- Place in to disable a speaker short from muting the amplifier.
PA2 CONT- Place in ,to link PA2 input to the control output.
