ENGLISH PV® 3800 Power Amplifier Congratulations on your purchase of the PV 3800, a power amplifier designed for years of reliable, flawless operation under rigorous use. This amplifier offers the sonic superiority and unsurpassed reliability for which Peavey is famous, while remaining surprisingly compact. Advanced technology and extensive protection circuitry allow operation with greater efficiency into difficult loads and power conditions.
SAVE THESE INSTRUCTIONS 1 Save the carton and packing materials! Should you ever need to ship the unit, use only the original factory packing. 9 Power down and disconnect units For replacement packaging, call Peavey Customer Service Department directly. nal level greater than that required to enable equipment to reach full output. 2 Read all documentation before operating your equipment. Retain all documentation for future reference.
Installation Unpacking Upon unpacking, inspect the amplifier. If you find any damage, notify your supplier immediately. Only the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to save the carton and all packing materials. Should you ever need to ship the unit back to Peavey, one of its offices, service centers or the supplier, use only the original factory packing. If the shipping carton is unavailable, contact Peavey to obtain a replacement.
Front Panel 2 3 1 4 5 1 AC POWER SWITCH/CIRCUIT BREAKER The PV® 3800 amplifier has a combination AC switch/circuit breaker on the front panel. 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 conditions.
Rear Panel 7 6 9 6 8 10 11 AC POWER INLET: This is the receptacle for an IEC line cord, which provides AC power to the unit. Connect the line cord to this connector to provide power to the unit. Damage to the equipment may result if improper line voltage is used. (See line voltage marking on unit). Never break off the ground pin on any equipment. It is provided for your safety.
Rear Panel 12 7 6 9 8 10 11 13 routed directly to the respective power amp channel. The crossover frequency is fixed at 100 Hz and cannot be changed. The crossover configuration is a four-pole Linkwitz-Riley approximation. 9 HIGH OUT JACKS 10 CONN. MODE SELECT SWITCH This 1/4” jack supplies high-frequency output signals from the activated crossover for patching to this amplifier and/or additional power amplifier inputs.
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 output.
Protection Features The PV® 3800 amplifier incorporates several circuits to protect both themselves and loudspeakers under virtually 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 percentage or output power are instantly reduced.
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.
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.
