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 CS2000H power requirements are rated at 1/8 power (typical music conditions) and 1/3 power (extreme 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.

Parallel

For parallel (dual-channel/single input) operation, turn the amplifier off and set the mode switch in the parallel position; both amplifier channels are then driven by the signal at Channel A’s input. No jumper wires are needed. Output connections are the same as in the stereo mode. In the parallel mode, only Channel A’s input is active; Channel B’s is out-of-circuit. Both input attenuators remain active, allowing you to set different levels for each channel. Power and other general performance specifications are the same as in the stereo mode.

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; potentially lethal 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 and connect the speakers across the hot outputs (the “+” binding posts of Channels A and B).

Unlike the stereo and parallel modes, in which one side of each output is at ground, in the bridged mode both sides are hot. Channel A’s side is the same polarity as the input. For proper operation, both input attenuators must be in the same position. This keeps the load balanced between the channel outputs. As in the parallel mode, only Channel A’s input is active. 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 will activate the DDT circuitry resulting in a loss of power, and may also cause a thermal overload.
