Description

The Electra-Voice Eliminator' amplifier is a
very high-quality power amplifier designed
to elicit excellent performance from any
speaker system Its low distortion and sub-
stantial headroom ensure tltat program ma-
terial will be accurately amplified.

Each channel of the Eliminator" amplifier
delivers more than 300-watts continuous
average power into 8 ohms, 500 watts into
4 ohms and 650 watts into 2 ohms overthe
full audio frequency range. In the bridged
mode. the amplifier can deliver more than
1,200 watts into 8 ohms and 1,700 warts into
4 ohms at less than 1% 'IHD. The power
supply with its large torodial transformer
gives the amplifier impressive headroom and
current output capability

The Eliminator amplifier contains 20 high-
power output devices with 5,000 watts of
dissipation capability. These devices are pro-
tected from overheating by two. three-speed
temperature-sensitive fans. The fans are quiet
enough to permit use of the Eliminator' am-
plifier in noise-sensitive applications such as
recording studios and houses of worship.
The output devices are mounted to two large,
extruded aluminum heat sinks that are engi-

neered to minimize themal gradients and
allow the amplifier to operate safely into low
impedance loads. The output devices have a
maximum junction temperature of 200° C
(392° F). so high operational temperatures
present no problems The output devices are
mounted directly to the heat sinks without
mica insulators to ensure better dissipation
of heat

The Eliminator amplifier has sophisticated
protection circuits that guard it and the load
from problems. Protection circuits guard
against overload. oveHemperature. shorted
outputs. radio-frequency interference and dc
faults. The output devices are protected
against damage from the reverse feeding of
electrical energy (back EMF) from the load
and are switched on via relays to avoid tran-
sients which could damage speakers.

The Eliminator amplifier has built-in lim-
iters to protect speakers from the deleterious
effects of amplifier clipping. The limiters
action is controlled by very sophisticated in-
put/output comparators which are designed
to preserve the sonic integrity of the source.
The Eliminator amplifier has electronically-
balanwd XLR-rype input and signal output
connectors that allow easy, problem~fiee con-
necuons and signal routing. The amplifier

has an input routing switch that allows se-
lection of either normal dual-channel opera-
tion or parallel mono operation. which routes
an input to both channels but still allows in-
dependent level conuoL

The EliminatorD amplifier professional Neu-
trik Speakon output connectors provide
sturdy, reliable connections and allow use of
heavy wire for loss-free signal transmission.
There are separate output connectors for
channels, A and B, and for the bridge mode.
The bridge mode connector is sealed with a
plastic cover to prevent connection errors.
To prevent ground loops from occurting, the
Eliminator amplifier is equipped with a
ground-lift switch. When the amplifier is
operated in a rack with units of different
ground potential. the switch may be adjusted
to eliminate hum

Separate potentiometers on the rear panel of
the Eliminatot amplifier allow easy regula-
tion of gain. There is easily readable nomen-
clature to ensure easily repeatable control
settings.

The Electro-Voice Eliminator amplifier is
an excellent choice for high-quality profes-
sional sound system applications which re-
quire excellent sound quality. speaker pro-
