User manual PEAVEY CS 800X

[. . . ] WARNING: When using electrical products, basic cautions should always be followed, including the following: Do not use this apparatus near water. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] Apply the signal to Channel A's input (all Channel B's input functions are defeated) and connect the speakers across the hot outputs (the "+" binding posts of Channels A and B) or between the 1+ and 2+ pins of the Channel A Speakon® connector. The input level control for channel A will be the master control for input level, the level control for the B channel is inoperative. 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. 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 . 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. 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. 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. When a problem occurs that causes a channel to go into a protection mode, the TEMP LED or DC LED for that channel will glow. Peavey's DDT compression system allows maximum performance of the amplifier/speaker combination by preventing the power amp from running out of headrooom (clipping). At power-up, the amplifier stays in the protect mode, with outputs disconnected, for approximately two seconds while the power supplies charge and stabilize. When power is removed, the speaker loads immediately disconnect so that no thumps or pops are heard. Whenever amplifier powers up or comes out of a protect mode, the RampUpTM circuit activates.
