6) SPEAKER TERMINALS

пет SWITCH
(FOR EACH
CHANNEL)
Connects or isolates the ground of XLR-pin 1. Usually left
ON.

in some
cases
where ground
loops are
causing hum, "lifting" the ground by turning this switch
OFF can interrupt the loop, thereby reducing hum.

When set to МОМО, this switch allows bridged (mono)
operation of the amplifier. The speaker terminals should
be connected to the "+" terminals of both channels (CH-A
to the speaker "+" and CH-B to the speaker "-"). When
using the PC4002/4002M
in BTL (MONO)
mode, соп-
nection should be.made to CH-A input only.
