PV® SERIES PROFESSIONAL STEREO POWER AMPLIFIER
INTRODUCTION
Congratulations! You have just purchased one of the world’s finest professional power amplifiers. The PV amplifier
features a two-way crossover and sub-sonic (low-cut) filter for each channel. Crossover frequencies are fixed at 150 Hz,
allowing subwoofers to be driven at extremely high sound pressure levels, and the filters cut at 40 Hz to prevent low-end
rumble. Using proven technology gained through years of amplifier design, this unit takes advantage of rugged TO-3P
output devices mounted on massive aluminum extrusions and dissipates heat via an extremely quiet and effective
two-speed fan. PV amplifiers are designed to operate at line voltages as low as 50% of nominal, employing mammoth
toroidal power transformers and offering impressive specifications and features not found on similarly priced competitive
units. This amp is designed to drive a 2-Ohm load per channel, thus achieving awesome performance levels into 4
Ohms in BRIDGE mode. PV amplifiers are ruggedly constructed, rack-mountable pieces of gear with superb patching
capability, allowing superior flexibility in application. Front panel features include calibrated, detented gain (dB) controls
and LED indicators for power (PWR), signal presence (SIG), Thermal Protection indicator, and DDT™ activation on each
channel, as well as a rocker mains POWER switch. The back panel contains an IEC connector, line voltage selector
switch, dual primary fuses, and the critical cooling fan opening. This opening should have an adequate supply of cool air
and should never be blocked or restricted. Also on the back panel are the input and output sections, including an input
barrier strip for permanent installations. Each channel input section includes a combo XLR / TRS phone jack connector,
THRU/LOW out and HIGH out TRS jacks, and activation switches for the LOW CUT filter and crossover (150 Hz
XOVER). Channel output sections feature dual shock-proof binding posts and four-conductor twist lock connectors. An
additional four-conductor twist lock connector allows BRIDGE mode output.
UNPACKING
Inspect the amplifier during unpacking. If any damage is found, notify your dealer immediately. Be sure to save the
carton and all packing materials. Should you ever need to ship the unit back to Peavey Electronics, one of its service
centers, or the dealer; use only the original factory packing.
INSTALLATION
PV professional power amplifiers are designed for durability in commercial installations and provide the quality
performance required in studio and home applications. They are two-rack-space units of 16" (406 mm) depth designed
to mount in a standard 19" rack. Rear mounting ears are provided for additional support. The minimum rack depth
required from the mounting surface is 17" (432 mm) to allow adequate connector clearance.
BASIC SETUP
Before mounting, make sure the line voltage selector is set to the correct voltage (page 9).
Rack mount the amplifier in the location where it is to be used, remembering to allow for adequate access and cooling
space. Make all the connections to the desired INPUT connectors on the desired channel. Select the proper mode
configuration (STEREO or BRIDGE). Connect speakers to the desired OUTPUT connectors.
Make sure the load impedance is greater than 2 ohms per channel (4 ohms bridged) to prevent the amplifier from
shutting down. With the POWER switch OFF, connect the IEC cord (7) to the amplifier and then to an outlet of the
proper voltage. With both channel gain controls turned fully counterclockwise, turn the Power switch on, and raise the
gain controls to achieve the desired sound level. Please carefully review this manual to learn about all the features and
designed-in behaviors of your new PV® Series power amplifier!
