SPEAKER TERMINALS (FOR EACH CHANNEL)
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 LIFT 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.
© INPUT CONNECTORS (XLR-3-31)
These female input connectors are usually used as inputs.
They are wired: Pinl =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.
0 PHONE INPUT CONNECTORS
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 MONO, 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, con¬
nection should be made to CH-A input only.
