A A Intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: Risk of electrical shock - DO NOT OPEN! CAUTION: To reduce the risk of electric shock, do not remove cover. No user serviceable parts inside.
A WARNING! For optimum performance and reliability DO NOT PRESENT THE AMPLIFIER WITH A SPEAKER LOAD OF LESS THAN 2 OHMS, OR A COMBINATION OF SPEAKERS THAT TOGETHER ARE LESS THAN 2 OHMS! Using one speaker, it must be rated at 2 ohms minimum. Using two speakers, they must be rated each at 4 ohms minimum. Using three speakers, they must be rated each at 8 ohms minimum. The world-famous C!F 1000 power amplifier has been changed to the new, extended-performance CS@ 1000X.
DDTTM ACTIVE LEDs (1) The DDTTM active LEDs indicate when compression is taking place. As long as gain reduction is occurring, the LED will continue to light, thereby giving a valuable indication of this unique compression function. The DDT function can be defeated on both channels simultaneously by selecting the defeat position on the DDT compression switch (7) located on the back panel of the CS 1000X.
conditions. Next to each ladder the calibration is “dB below full power.” This is a convenient scale that indicates the amount of power amp headroom left for any signal condition. INPUT SENSITIVITY CONTROLS (4) The CS 1000X features a 31 detent, calibrated sensitivity control for each channel. Each control is labeled to show the actual input sensitivity ratings of the amplifier for various settings in decibel volts necessary to attain the full-output power rating.
Never break off the ground pin on the CS 1000X or any amplifier. The use of extension cords should be avoided, but if essential, always use a three-wire type with at least a #14 AWG wire size. The use of lighter wire will severely limit the power capability of this amplifier. Always use a qualified electrician to install any necessary electrical equipment. To prevent the risk of shock or fire hazard, always be sure that the amplifier is properly grounded.
LOW-Z INPUTS (11) Conventional three-pin, female XLR input jacks are provided, which can be used as either the channel inputs or the crossover inputs, depending upon what has been plugged into the crossover socket (14). Further, this XLR input is balanced or unbalanced, depending upon what is plugged into the transformer socket (12).
SPEAKER OUTPUTS (18) (19) Two l/4” jacks and 5-way binding post speaker output terminals are provided for each channel, with all the outputs from each channel in parallel. Thus, the loudspeaker connection cables can be terminated with l/4” phone plugs, banana plugs, or stripped wires for use in the binding post terminals. For sustained high-power applications, the use of the binding post terminals is highly recommended; however, care must be exercised to assure correct speaker phasing.
PORTABLE RACK-MOUNT APPLICATIONS Due to the weight of the CS 1000X, we highly recommend that some additional support be provided at the back panel of the amplifier whenever units are installed in a portable rack-mount configuration. Two l/4-20 allen-head bolts have been provided at the rear of the CS 1000X for this purpose. These bolts should be attached to a suitable bracketing arrangement to provide this additional support.
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 1000X 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 connectors (11) are to be used as inputs for each channel.

BIAMP STEREO MODE The Peavey CS-1000X patch panel can also be used to biamp and/or provide special equalization capabilities for loudspeaker systems.

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.
associated loudspeaker components. To help prevent this, whenever the bridge mode is selected, the standby (“0”) LED and the LED array itself on Channel B is defeated (off), just as if there was some kind of a fault condition present on Channel B. This provides a positive indication that the CS 1000X is no longer in the stereo mode.
Often studio engineers feel the need to defeat the DDT compressor, for fear it might color the sound in studio listening. The DDT compressor is only activated when clipping is imminent. Until this occurs, it’s simply a passive friend. The only reason the defeat switch is there in the first place is to allow check-out technicians to evaluate the power amplifier at clipping. Valuable performance information, such as powersupply ripple and regulation, can only be assessed when an amplifier is allowed to clip.
The term headroom deserves some consideration. Program material (music or speech) is made up of many different frequencies and their harmonics. Most music, especially contemporary rock music, is bass-heavy. That is, the low-frequency material contains much more energy than the high-frequency material.
5. A 6. unbalanced), the crossover input jacks (13) can be used to patch out full-range signals to other amplifier/speaker systems that are operating in full range or other biamped systems that require different crossovers. Care must be taken never to remove or replace a crossover module with the CS 1000X power switch on.
3. 4. 5. A A A shorted across itself. Remember, just as in the stereo mode, the power LED array (Channel A) should reach 100% indication before the DDT system is activated on both channels. The jumper plug in the transformer accessory socket (12) of channel A island can be replaced with a PL-2 transformer module. This will convert the XLR connector on Island A to balanced operation and provide a balanced input for the bridged CS 1000X.
