Peavey CS 800H Connecting Inputs, Connecting Outputs, Connecting Power, Stereo, Bridged Mono

Operation Modes

Connecting Inputs

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.

Connecting Outputs

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.

Connecting Power

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

Stereo

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.

Bridged Mono

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.
