The red speaker terminal should be connected to the "+"
terminal of the speaker system, and the black terminal to
the "-" channel. (In the above illustration, terminal covers
are not shown. See page 5)
@ GROUND пет SWITCH (FOR EACH CHANNEL)
Connects or isolates the ground of XLR-pin 1. Usually left
ON. However, in some cases where ground loops are
causing hum, "lifting" the ground by turning this switch
OFF can interrupt the loop, thereby reducing hum.

These female input connectors are usually used as inputs.
They are wired: Pin1=ground, Pin2=hot, Pin3=cold.
Compatible connectors include ITT-Cannon XLR-3-12C,
Switchcraft 5C-1055A and Neutric NC3MX.

@ INPUT CONNECTORS (XLR-3-32)
These male inputs duplicate the female input connectors
(same wiring), but are usually used for retransmitting the
input signal to other amplifiers. Compatible connectors
include ITT-Cannon XLR-3-11C, Switchcraft 5C-1056A
and Neutric NC3FX.

These 1/4-inch balanced TRS connectors accept balanced
and unblanced input signals. Tip=hot, Ring=cold,
Sleeve=ground.
@ MODE SELECTOR SWITCH (BTL) |
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.
