User manual PEAVEY CS 800X

[. . . ] Before using this appliance, read the operating guide for further warnings. WARNING: When using electrical products, basic cautions should always be followed, including the following: Do not use this apparatus near water. Do not block any of the ventilation openings. install in accordance with manufacturer's instructions. [. . . ] The active LED for the B channel will not light, which makes it easy to identify when the amp is in Bridge mode. Unlike stereo mode, in which one side of each output is at ground, in the bridged mode both sides are hot. If an output patch panel is used, all connections must be isolated from each other and from the panel. The recommended minimum nominal load impedance in the bridged mode is 4 Ohms (equivalent to driving both channels at 2 Ohms). Driving bridged loads of less than 4 Ohms can activate the Load Fault Correction (LFC) circuitry resulting in a limiting of power, and may also cause a thermal overload. If the switch shuts off during normal use, push it back to the ON position once. If it will not stay on, the amplifier needs servicing. The input attenuator controls (one for channel A, one for channel B) located at the front panel adjust gain for their respective amplifier channels in all modes. These LED indicators inform the user of each channel's operating status and warn of possible abnormal conditions. This amplifier also features two 10-segment bar graph indicators per channel: SIGNAL . This LED is at the bottom of the bar graph display and lights when its channel produces an output signal of greater than 2 Volts RMS or 50 mV input with a 0 dB attenuation of the front panel knobs. This connector allows patching the frequencies above the crossover knob setting to a secondary amplifier. This output remains at low frequencies independent of the Amp Function switch setting. Each channel features a pair of shock-proof binding posts connected in parallel with the Speakon connector. The red binding posts are the signal output from each channel, and the black binding posts are chassis ground. For Bridge mode operation, only the red binding posts are used. The Channel A red binding post should be considered the positive output for the system and should be connected to the positive input of the associated loudspeaker system. Provided to accept the removable (IEC) type AC line cord. Connect only to proper source (see back panel markings). The CS 800X incorporates several circuits to protect both itself and loudspeakers under virtually any situation. Peavey has attempted to make the amplifier as foolproof as possible by making it immune to short and open circuits, mismatched loads, DC voltage, and overheating. If a channel goes into the Distortion Detection or DDT gain reduction mode, the speaker load remains connected, but clipping percentage or output power are instantly reduced.
