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.
