WARNING! A 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 1000 power amplifier has been changed to the new, extended-performance 1000X. This upgraded model provides impre

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. When the compressor is defeated, the DDT active LED will indicate clipping, this being the condition where th

INPUT SENSITIVITY CONTROLS (4) The CS 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. Thus, maximum input gain (minimum sensi

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 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. CIRCUIT BREAKER (9) The new CS 1000X now fe

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). Fur- ther, this XLR input is balanced or unbalanced, depending upon what is plugged into the transformer socket (12). When the (PL-2) line-balancing transformer is used in socket this XLR input becomes fully TRANSFORMER-BALANCED, with pin as the positive input and pin as the n

SPEAKER OUTPUTS (18) (19) Two l/4” jacks and 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 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. Regardless of what

PORTABLE RACK-MOUNT APPLICATIONS Due to the weight of the CS 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 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. Also, two guards have been provided on the rear panel of the CS 1000X to protect conne

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. As indicated in Diagram 1, the XLR connectors are wired in an unbalanced configurati

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 supply ripple and regulation, can only be assessed when an amplifier is allowed t

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. If both high- and low-frequency material, such as voice and bass guitar, are present in a full-range system, the energy bass frequencies can use up most of the power available from the power ampli

Care must be taken never to remove or replace a crossover module with the 1000X power switch on. The complex circuitry used in the crossover modules receives bipolar power through the socket, and removal or replacement could cause severe transients that can destroy the loudspeake

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 1000X. 4. The jumper plug in the crossover accessory socket (14) of the Channel A
