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 1000, 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 isolated (no longer connected to anything). In other words, the crossover modules and all associated connectors (as well as the PL2 transformers and respective XLR connectors) are islands unto themselves: in this case, two islands with @ PATCH PANEL (STEREO MODE) WITH CROSSOVER AND INPUT TRANSFORMER MODULES TRANSFORMER I- GROlJND 2 NEGATIVE 3 POSlTl"E I X-OVER BRIDGE SENSITIVITY STEREO TRANSFORMER (PL-2 MODULE) 2 NEGATIVE 3 POSITIVE X-OVER 11 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. 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 1000 can be patched for the lows and the other channel patched for the highs, resulting in a simple, compact system with outstanding performance. CAUTION: Since the CS 1000 is capable of producing more than 500 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. BRIDGE MODE Diagram 4 shows the actual arrangement for the CS 1000 patch panel in the bridge mode. DDTTM COMPRESSION The CS 1000 is a compact and powerful amplifier that features a new type of dynamic compression. This compression system enables the user to maximize the performance of the amplifier/speaker combination. We have determined through much research that the compression circuitry should prevent the power amplifier from running out of headroom (clipping) and should be as simple to operate as possible to avoid undue complication for the user. This compression system is activated by our exclusive DDT compression circuitry, which senses conditions that might overload the amplifier and activates compression when clipping is imminent. In other words, compression takes place whenever signal conditions exist that prevent the amplifiers from faithfully reproducing the input signal. In this case, threshold is clipping itself, and no specific threshold control is provided. This technique effectively utilizes every precious watt available from the power amplifier. Techniques using external compressors/limiters are usually less effective, severely limit output power levels and require additional controls, and add complexity to an already complicated system. The DDT system is an automatic, hands-off approach to the problem of amp clipping. Because of the dynamics of music and vocals, it is quite common to activate the DDT compression circuitry almost constantly during a high-level performance, since this is what it was designed to do: i. e. , to maximize the dynamics available from the amplifier within its power-output capabilities regardless of power supply/AC line voltage variations and load impedance selection. Defeating the DDT compression should be very carefully considered before one just "flips the switch. " Most loudspeaker systems simply cannot handle the square wave power of the CS 1000, and defeating the DDT system opens up the door for severe clipping!
