DESCRIPTION
The Electro-Voice P2000 Precision SeriesTM
amplifier is a very-high-quality power amplifier
designed to elicit maximum performance from
any speaker system. Its ultralow distortion and
powerful amplifiers ensure that program material
will be amplified very accurately.
Each channel of the P2000 delivers more than
500 watts continuous average power into
8 ohms, 800 watts into 4 ohms and 1,000 watts
into 2 ohms over the full audio frequency range.
In the bridge mode, the amplifier can deliver
more than 1,600 watts into 8 ohms and 2,000
watts into 4 ohms at less than 1% THD. The
power supply, with its large toroidal transformer,
gives the amplifier impressive headroom and
current output.
The P2000 contains 32 high-power output devices
with 8,000 watts of dissipation capability.
These devices are protected from overheating
by four, three-speed, temperature-sensitive
fans. The fans are quiet enough to permit use of
the P2000 in noise-sensitive applications such
as recording studios and houses of worship.
The output devices are mounted to a massive,
extruded-aluminum heat sink that is engineered
to minimize thermal 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 sink without mica insulators to ensure
better dissipation of heat.
Many electronic circuit innovations exist in the
P2000. Among the most novel of these circuits
is the Mirrored Frontend Power Supply BridgeTM.
This design ensures complete symmetry for
each bridged amplifier and both signal polarities,
and eliminates asymmetrical rise and fall
times. The Dual Differential Discrete TopologyTM
is part of the front end of the amplifier and uses
discrete electrical components instead of integrated
circuits to help the P2000 achieve its
phenomenally low distortion.
The P2000 has sophisticated protection circuits
that guard it and the load from problems.
Protection circuits guard against overload,
overtemperature, shorted outputs, radio-frequency
interference and dc faults. The output
devices are protected against damage from
reverse feeding of electrical energy (back EMF)
and are switched on via relays to avoid transients
which could damage speakers.
The P2000 has built-in limiters to protect speakers
from the deleterious effects of amplifier
clipping. The limiter’s action is governed by
very sophisticated input/output comparators
which have acoustically optimized time constants
to preserve the integrity of the source.
The limiter’s time constants are switchable fast/
slow, so the limiter may be matched to the
application for which the amplifier is being
used.
The P2000 has built-in switchable high- and
low-cut filters. These filters attenuate infrasonic
and ultrahigh-frequency signals, preventing
them from being amplified; this allows more
effective use of the amplifier’s power and adds
a measure of load protection. These filters are
switchable on/off for use in applications utilizing
frontend units (like crossovers or equalizers)
which have these filters built-in.
A multifunction display keeps the user informed
of the operating status of the amplifier. Separate
LED displays for each channel show power
on, input signal, output signal, limiter on and
protection active.
The P2000 has electronically balanced XLRtype
input and output connectors that allow
easy, problem-free connections and signal
routing. The P2000 has an input routing switch
that allows selection of either normal dualchannel
operation, or parallel mono operation,
which routes an input to both channels but still
allows for independent level control. The P2000
also has a constant-gain option which allows
the voltage gain to be fixed. This permits different
amplifiers to be used in fixed installations
without rebalancing, and ensures headroom is
not wasted.
The P2000’s professional Neutrik Speakon®
output connectors provide a sturdy, reliable
connection and allow use of heavy wire for lossfree
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 occurring, the
P2000 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.
Calibrated, detented potentiometers on the front
panel regulate the gain of the P2000. The panel
nomenclature shows the amount of attenuation
accurately.
The P2000 also has a constant-gain option
which, with input level controls full clockwise,
provides a 26-dB voltage gain that is identical to
that of all Electro-Voice Precision SeriesTM amplifiers
in the constant-gain option, regardless
of power rating. This makes it possible to exchange
amplifiers of different power ratings
without upsetting delivered sound pressure levels
or spectral balances.
The Electro-Voice P2000 is the choice for serious,
professional amplification applications
which require optimum sound quality, speaker
protection, and the ighest level of construction
quality and long-term reliability.
