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. INDICATORS The PV 3800 amplifier features three front panel LED indicators per channel: DDT™, SIGNAL and POWER. These LED indicators inform the user of each channel’s operating status and warn of possible abnormal

Operation Modes Stereo Operation For stereo (dual channel) operation, turn the amplifier off and set the mode select switches on the back panel to the OUT (extended) position. In this mode, both channels operate independently of each other with their input attenuators controlling their respective levels. For example, a signal at channel A’s input produces an amplified signal at channel A’s output, while a signal at channel B’s input produces an amplified signal at channel B’s out- put. Paral

Protection Features The PV® 3800 amplifier incorporates several circuits to protect both themselves and loudspeakers under virtu- ally any situation. Peavey has attempted to make the amplifiers as foolproof as possible by making them immune to short and open circuits, mismatched loads, DC voltage, and overheating. If a channel goes into the Distortion Detection Technique or DDT™ gain reduction mode, the speaker load remains connected, but clipping percent- age or output power are instantly red

Protection Features Turn-On/Turn-Off Protection At power-up, the amplifier stays in the protect mode with outputs disconnected for approximately six seconds while the power supplies charge and stabilize. While the output relays are open, the DDT™ LEDs light. When power is removed, the speaker loads immediately disconnect so that no thumps or pops are heard. RAMPUP™ Signal Control Whenever a PV® 3800 amplifier powers up or comes out of a protect mode, the RAMPUP circuit activates. While the

Safety Speaker Protection All loudspeakers have electrical, thermal and physical limits that must be observed to prevent damage or failure. Too much power, low frequencies applied to high frequency drivers, severely clipped waveforms and DC voltage can all be fatal to cone and compression drivers. The Peavey PV® 3800 amplifier automatically protects speakers from DC voltages and subsonic signals. For more information, see the section on Protection Features. Mid- and high-frequency speakers,
