Input connections are made via the 3-pin XLR (pin 2+) or 6.3 mm plug “Combi” connectors on the
rear panel of the amplifier. The inputs are actively balanced. Pinout and polarity of connection
cables should be configured correctly (refer to the rear panel of the unit). The input overload
point is high enough to accept the maximum output level of virtually any signal source.

All models have two output (speaker) connections per channel. Cables can be connected with
banana plugs, spade lugs, or bare wire to the 5-way binding posts. The preferred connection
method is via the Speakon connectors. Pin connections are noted on the rear panel of the unit.

The CS 800H power requirements are rated at 1/8 power (typical music conditions). The
maximum power current draw rating is limited only by the front panel circuit breaker. Consult the
specifications in this manual for figures on the current that this amplifier will demand. Make sure
the mains voltage is correct and is the same as that printed on the rear of the amplifier. Damage
caused by connecting the amplifier to improper AC voltage is not covered by any warranty. Unless
otherwise specified when ordered, Peavey amplifiers shipped to customers are configured as
follows:
North America: 120 VAC/60 Hz
Europe, Asia, Australia: 230/240 VAC/50 Hz
South America: 120 VAC/60 Hz or 240 VAC/50 Hz

For stereo (dual channel) operation, turn the amplifier off and set the mode select switch to the
stereo position. In this mode, both channels operate independently of each other, with their
input attenuators controlling their respective levels. Thus, a signal at Channel A’s input produces
an amplified signal at Channel A’s output, while a signal at Channel B’s input produces an
amplified signal at Channel B’s output.

Both amplifier channels can be bridged together to make a very powerful single-channel
monaural amplifier. Use extreme caution when operating in the bridged mode; high voltage may
be present at the output terminals. To bridge the amplifier, set the rear panel mode select switch
to the bridge position. Apply the signal to Channel A’s input (all Channel B’s input functions are
defeated) and connect the speakers across the hot outputs (the “+” binding posts of Channels A
and B) or between the 1+ and 2+ pins of the Channel A Speakon
® connector. The input level
control for channel A will be the master control for input level, the level control for the B channel
is inoperative. The active LED for the B channel will not light, which makes it easy to identify
when the amp is in Bridge mode.
Unlike stereo mode, in which one side of each output is at ground, in the bridged mode both
sides are hot. If an output patch panel is used, all connections must be isolated from each other
and from the panel. The recommended minimum nominal load impedance in the bridged mode is
4 Ohms (equivalent to driving both channels at 2 Ohms). Driving bridged loads of less than 4
Ohms can activate the Load Fault Correction (LFC) circuitry resulting in a limiting of power, and
may also cause a thermal overload.
