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 fac- tory packing. If the shipping carton is unavailable, contact Peavey to obtain a replacement.

Because of the complexity of the de- sign and the risk of electrical shock, all repairs must be completed only by qualified technical personnel.

Mounting

The PV® 3800 amplifier will mount in standard 19" racks. Rear mounting ears are also provided for additional support, which is recommended in non-permanent installations like mobile or touring sound systems.

Connecting Power

The PV 3800 amplifier power re- quirements are rated at 1/8 power (typical music conditions) and 1/3 power (extreme music conditions). The maximum power current draw rating is limited only by the front panel circuit breaker. Consult the specifications in the Specification section for figures on the current that each amplifier will de- mand. Make sure the mains voltage is correct and is 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 warranty. Unless otherwise speci- fied when ordered, Peavey amplifiers shipped to customers are configured as follows:

Option 1 North America

120VAC / 60 Hz

Option 2 Europe, Asia

230/240VAC / 50 Hz

Option 3 Australia

240VAC / 50 Hz

Option 4 South America

120VAC / 60 Hz or 240VAC / 50 Hz

Always turn off and disconnect the amplifier	a
Always turn off and disconnect the amplifier
from mains voltage before making audio
connections. Also, as an extra precaution, turn the
attenuators down during power-up.

Cooling Requirements

The PV 3800 amplifier uses a forced-air cooling system to main- tain a low, consistent operating temperature. Air is drawn into the amplifier by fan(s) on the rear panel, courses through the cooling fins of the tunnel-configured channel heat sink(s), and then exhausts through the front panel grille. If either heat sink gets too hot, its sensing circuit will open the output relay, discon- necting the load from that particular channel. The PV 3800 utilizes one common heat sink and a single fan, but retains the separate circuitry. NOTE: Maintain an adequate air supply at the back of the amplifier and enough space around the front of the amplifier to allow the cooling

	air to escape. If the amp is rack	a
	mounted, do not use doors or	a
	mounted, do not use doors or
	covers on the front of the rack;
	the exhaust air must flow without
	resistance. If you are using racks

with closed backs, use fans on the rear rack panel to pressurize the rack and ensure an ample air supply.

Operating Precautions

Make sure the mains voltage is correct and the same as that printed on the rear of the amplifier. Damage caused by connect- ing the amplifier to improper AC voltage is not covered by any warranty. See the Connecting Power section for more informa- tion on voltage requirements.

Although the PV 3800 amplifier has RAMPUP™ circuitry, which raises the signal level gradually after the output relay closes, remember to have the gain controls turned down during power-up to prevent speaker damage if there is a high signal level at the inputs. Whether you buy or make them, use good-quality connections, input cables and speaker cables, along with good soldering technique, to ensure trouble-free operation. Most intermittent problems are caused by faulty cables.

Consult the Wire Gauge Chart to determine proper gauges for different load impedances and cable lengths. Remember that cable resistance robs amplifier power in two ways: power lost directly to resistance (I2R loss), and by increasing the total load impedance, thereby decreasing the power demanded of the amplifier. Also, make sure the mode switch is correctly set for the desired application. See Sections on Stereo, Parallel and Bridged Mono Mode for more information.

Make certain that there is enough space around the front and rear of the amplifier to allow the heated air to escape.

Suggestion: In racks with closed backs, allow at least one standard-rack-space opening for every four mounted power amplifiers.
