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.
CIRCUIT BREAKER (9)
AThe new CS 1000X now features a circuit breaker in place of the mains fuse. This breaker is provided to limit the mains current to the associated power transformer, thereby protecting it from overheating and possible destruction due to any fault conditions in the amplifier. The trip current value has been carefully chosen to allow continuous power output performance, while still providing adequate protection for the power transformer itself. Normally the breaker should not trip; however, abnormal conditions such as a short circuit on either or both channels, or continuous operation at overload or clipping, especially into a
2-ohm load, will cause the breaker to trip. If this occurs, simply reset the breaker and correct the cause of the overload. When tripped, the button on the breaker will be extended outward nearly l/2” and can be reset by pushing inward. A normal reset button length is about l/4”. If this “thermal”-type breaker does trip, simply pushing the button back in will reset it, after waiting a brief period of time to allow it to cool down. If the breaker trips instantly each time you attempt to reset it, then the unit should be taken to a qualified service center for repair.
The back panel of the CS 1000X features a unique “back-porch” design containing the various input and output connectors for each channel. A patch panel is also included, providing a very flexible system for use with balanced-input transformers and dual crossover networks. These features are unduplicated in any other stereo power amplifier on the market today.
MODE SWITCH (10)
The mode switch is located on the “back-porch” next to the channel input jacks. This switch converts the CS 1000X from normal stereo mode to bridge mode. Bridge-mode operation is very popular for commercial sound distribution systems (70/100 volt lines).
WARNING: In bridge mode, the CS 1000X is capable of delivering 1000 W RMS into 8 ohms and A 1500 W RMS into 4 ohms. Always be very certain that the associated loudspeaker system can handle this
power level reliably. Also, be advised that in most crossover applications, accidental switching to the bridge mode could destroy the speaker system. Specific applications of the bridge mode will be covered later in this manual.
