Peavey CS 1200X - Manual (Page 7)

MODE SWITCH (10)
The mode switch is located on the “back-porch” next to the channel input jacks. This switch
converts the CS
from normal stereo mode to bridge mode. Bridge-mode operation is very
popular for commercial sound distribution systems 00 volt lines).
A WARNING:
In bridge mode, the CS is capable of delivering 1200 W RMS into 8 ohms
and 1800 W RMS into 4 ohms. Always be very certain that the associated loudspeaker system
can handle this power level reliably. Also, be advised that in most crossover applications,
accidental switching to the bridge mode could destroy the speaker system. Specific applications
of the bridge mode will be covered later in this manual.
LOW-Z INPUTS (11)
Conventional three-pin, female XLR input jacks provided, which can be used as either the
channel inputs or the crossover inputs, depending upon what has been plugged into the crossover
socket (14). Further, this XLR input is balanced or unbalanced, depending upon what is plugged
into the transformer socket (12). When the (PL-2) line-balancing transformer is used in socket
this XLR input becomes fully TRANSFORMER-BALANCED, with pin as the positive
input and pin as the negative input. When a blank plug (PL- 1) is inserted in socket this
XLR input becomes unbalanced, with pin as positive input and pin as ground. If a
PL-MODULE ELECTRONIC CROSSOVER is plugged into socket the XLR input system
drives the crossover, but if a blank plug (PL-1) is inserted in socket the XLR input system
is connected directly to the channel power amp input.
TRANSFORMER RECEPTACLES (12)
These receptacles only receive the optional (PL-2) line-balancing transformer. When conditions
exist that demand the usage of a TRANSFORMER-BALANCED XLR at the input of a power
