isolated (no longer connected to anything). In other words, the crossover modules and all associ- ated connectors (as well as the PL-2 transformers and respective XLR connectors) are islands unto themselves: in this case, two islands with each crossover having a balanced input (1 l), dual (parallel) unbalanced inputs (13), an unbalanced low output (15), and an unbalanced high output (16). In order to complete the system, external patching must be accomplished between the low and high crossover outputs and the various power amp inputs using shielded patch cords. A patch diagram showing this arrangement is included at the end of this manual.

3A. BIAMP MONO MODE

Obviously, for a monaural biamp system (only one mixer feed), only one crossover module is required and only one crossover island will be used. In this case, one channel of the CS 1200X can be patched for the lows and the other channel patched for the highs, resulting in a simple, compact system with outstanding performance.

A CAUTION:

Since the CS 1200X is capable of producing more than 600 watts RMS per channel into a 4-ohm load, the high-frequency components of the particular loudspeaker system must be able to handle these power levels reliably. Alternatively, use a smaller power amplifier!

4. BRIDGE MODE

Diagram 4 shows the actual arrangement for the CS 1200X patch panel in the bridge mode. Notice that the jumper plugs are inserted in the transformer (12) and crossover (14) accessory sockets of Island A. These jumper plugs cause the XLR connector of this island to be wired in the unbalanced configuration (as in Diagram 1) and complete the connection to the Channel A power amp input jacks (which are now the only active inputs). The Channel A sensitivity control now determines the sensitivity of the bridge-mode amplifier. The Channel B input jacks and sensitivity control serve no purpose in this mode, and are actually electronically removed from the circuit. Both sets of parallel l/4” output phone jacks are also not normally used in the bridge
