[. . . ] Before using this apparatus, 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. [. . . ] Cooling Requirements CS Series amplifiers use a forced-air cooling system to maintain a low, consistent operating temperature. Air is drawn into the amplifier by fans on the back panel and courses through the cooling fins of the tunnel-configured channel heat sinks, then exhausts through the front panel grilles. If either heat sink gets too hot, a sensing circuit will mute the signal for that particular channel. It is important to have an air inlet at the back of the amplifier to allow cooling air to enter. If the amp is rack mounted, do not use doors or covers on the back of the rack, as the intake air must flow without resistance. Make sure that there is one (1) standard rack space opening for every three mounted power amplifiers. Operating Precautions Make sure the mains voltage is correct and the same as that printed on the rear of the amplifier. Damage caused by connecting the amplifier to improper AC voltage is not covered by any CS® Series warranty. see the Connecting Power section for more information on voltage requirements. Note: Always turn off and disconnect the amplifier from mains voltage before making audio connections. also , as an extra precaution , have the attenuators turned down during power-up. The input attenuator controls (one for channel A, one for channel B) located on the front panel attenuate signal level (decrease gain) for the respective amplifier channels in all modes. Do not operate the Bridge Select switch with the amplifier powered on. see the sections on Stereo and Bridged Mono mode for more information. DDTTM Defeat Switch (4) For normal operation, the DDT circuit should remain operational by leaving the DDT Defeat Switch in the extended position. These LED indicators inform the user of each channel's operating status and warn of possible abnormal conditions. SIG LED (2) The Signal LED illuminates when its channel produces an output signal of greater than 1 volt RMS or 25 mV input with a O dB attenuation of the front panel knobs. This is useful in determining whether a signal is reaching and being amplified by the amplifier. If the Signal LED is illuminated but no sound is present, that means a signal is present at the amplifier but a problem may exist after the amplifier, such as in the cables or speakers. dDT LED (3) A channel's DDT LED will illuminate at the onset of clipping. If the LEDs are flashing quickly and intermittently, the channel is just at the clip threshold, while a steady, bright glow means the amp is clip limiting, or reducing gain to prevent severely clipped waveforms from reaching the speakers. The Peavey CS Series incorporates several circuits to protect the amplifier and speakers under virtually any situation. [. . . ] Turn-On/Turn-Off Protection Upon powering up, the amplifier stays in Protect mode, muting the input signal for approximately four seconds while the power supplies charge and stabilize. Read the Speaker Protection section and always be aware of the speaker's continuous and peak power capabilities. In the unlikely event that your amplifier develops a problem, it must be returned to an authorized distributor, service center or shipped directly to our factory. To obtain service, contact your nearest Peavey Service Center, Distributor, Dealer, or any of the worldwide Peavey offices. [. . . ]
