2. STEREO MODE (BALANCED INPUTS)

When conditions require the use of a balanced input at the power amplifier, the XLR connectors

(11)on either or both channels can be converted to a balanced configuration by removing the jumper plug from the transformer accessory socket (12) and plugging in an input transformer module (PL-2). The Peavey model PL-2 transformer module is a nominal 1: 1 turn-ratio type, resulting in unity gain. In Diagram 2, the XLR connector is now wired as a conventional bal- anced-type input (pin 1 is ground; pin 2 is negative; pin 3 is positive). The jumper plugs in the crossover accessory sockets are required to complete the signal patch to the respective power amp inputs (14). For balanced stereo operation, two PL-2 modules are required. For monaural operation, only one PL-2 is needed, and the inputs can be connected by placing a short shielded jumper cable between one of the power amp input jacks (17) on each channel. Thus, the XLR connector associated with the PL-2 module is the balanced-system input, and the other XLR connector is not used.

3.BIAMP STEREO MODE

The Peavey CS-1200X patch panel can also be used to biamp and/or provide special equalization capabilities for loudspeaker systems. Various electronic crossovers and special purpose modules are available in a broad range of frequencies for both Peavey and non-Peavey loudspeaker systems. More complicated systems, such as stereo biamped, triamped, or even 4-way crossover systems are possible. We suggest you contact your Authorized Peavey Dealer for details. A typical stereo biamp system will be discussed in this manual. Referring to Diagram 3, the jumper plugs in both crossover accessory sockets (14) have been replaced by two-way crossover mod- ules. Also, notice that the PL-2 transformer modules are still in the transformer accessory sockets (12). This configuration now has the makings of a complete stereo-balanced biamp system. The only thing required is an additional stereo power amplifier, which, together with the existing dual power amp sections of the CS 1200X, makes up the four independent power amplifiers required for a stereo biamplification system. You will notice that because of the pin-out arrangements of the jumper plugs versus the crossover networks, whenever the jumper plugs are removed from the crossover accessory sockets (14), the power amplifier inputs for the respective channels are
