Operation

The CS 1200X is designed for maximum ease and flexibility of operation. When the unit is installed and connected as described in the previous sections, operation is as simple as turning on the mains switch (S), turning up the sensitivity controls (4) to the full clockwise setting, and then adjusting the associated mixer or pre-amplification equipment to supply the necessary signal levels to provide the desired output level or until the front panel DDT active LED indicator shows that the amplifier is compressin g. Further increases in signal levels beyond this point will not produce any significant increase in output and may cause distortion problems.

MODES OF OPERATION

1. STEREO MODE (UNBALANCED INPUTS)

The CS 1200X is shipped from the factory with jumper plugs inserted in the transformer ( 12) and crossover (14) accessory sockets. These jumper plugs are necessary if the low-impedance con- nectors (11) are to be used as inputs for each channel. As indicated in Diagram 1, the XLR connectors are wired in an unbalanced configuration (pins 1 and 2 are ground: pin 3 is input). The unbalanced-input configuration is acceptable whenever relatively short cable runs are em- ployed, or when the associated mixer used has a full transformer-balanced output. Under these circumstances, this configuration will usually provide adequate hum and interference rc.jection for most environments. Notice that the jumper plugs in the crossover accessory sockets arc required to complete the signal patch to the respective power amp inputs ( 17). If‘ the normal unbalanced l/4” power amp input jacks are used instead, the jumper plugs are not necessary. It is suggested, however, that they be left in their respective sockets for possible later usage. As with all Peavey amplifiers, the CS 1200X has two power amp input jacks per channel ( 17), which offer considerable flexibility in hook-up possibilities. For monaural operation, the same signal is applied to both channels; the mixer output is plugged in one of the parallel input jacks in one of the channels, and a short shielded jumper cable is connected between the remaining input jack on that channel to one of the parallel input jacks on the other channel. This technique is called daisy-chaining, and can be repeated many times to patch to additional amplifier channels requir- ing the same signal feed.
