Description

The Electro-Voice APZROU dual-channel
power amplifier is designed for direct mice-
cotl drive andmr 704 ll disin buted s) stems
Each channel can be independently config-
ured for 70-iolt lint: operation or tin-ohm
systems. The two channels can he paralleled
or bridged for driving a single load.

This amplifier leatures an ultraquiet. continu-
ously variable cooling system which pulls
air from front to tear in a directed fashion
which focuses the air flow on the critical
components. A remoi able air filter is in-
corporated into the tront grille allowing easy
access for cleaning or replacement,

The signal input module is removable and
comes standard with both XLR and screw
terminal connectors. Optional Signal pro-
cessing PCBs plug directl} onto the Input

Architects' and Engineers'
Specifications

The power amplifier shall be a three-rack

space. dual-channel amplifier providing
l0tl watts per channel in dual channel mode.
The amplifier will provide an incorporated
means to independently configure each chan-
nel for either Sl-l-ohm loads or 70~volt line
operation.

The amplifier shall have a switchable con-
figuration between dual-chartnel, parallel
mono and bridged mono mode. The ampli-
fier will also provide a guard against illegal
mode operation with a Visual indicator as
well as disabling operation until channel load
configurations correspond to output configu-
ration mode. Bridged mono output mode
shall prmide a differential balanced signal
to the speaker load.

The amplifier will incorporate a directed air-
flow cooling system utilizing an ultmquiel
continuously variable cross-flow fan pulling
air from the front and pushing air out the
rear ol'tlie amplifier. The unit will provide a
trnnt»accessible air filter.

The amplifier shall incorporate interchangahle
signal input modules which provide for Slg<
rial processing PCBs to be directly connected
lit the module without replacement. input
modules wull provide both XLR and screw
terminal connectors in a parallel Circuit. In-

put module pinouts shall he published in-
formation. The amplifier will provide for
optional Interactive Technology control mod-
ules to be used.

The amplifier shall meet the following
performance criteria. Rated power in dual-
channel mode: 4-ohm = 500 watts. 8-ohm =
400 watts. 70-volt = 400 watts; rated power
in parallel mono mode: l-ohm = LOOO watts.
4-ahm : 800 watts. 8«ohm = 400 watts.
70-volt = 800 watts: rated power in bridged
mono mode: S-ohm = l,000 watts. lfi-ohm
= 800 watts. 70-volt = 800 watts. Hamill =
800 watts.

The power amplifier shall he 482.6 mm
(19 in.) wide by 425.5 mm ( l6.75 in.) deep
by l33.4 mm (5.25 in.) high and weigh
24.4 kg (53.9 lb).

The power amplifier shall be the Elcclm-
Voicc AP2800.
