The Extron XTRA™ Series XPA 4002 is a 1U, convection-cooled power amplifier delivering two channels of 400 watts rms. This professional grade amplifier features a 100 dB signal-to-noise ratio with 0.1% THD+N. The XPA 4002 is an ENERGY STAR® qualified amplifier with an Extron exclusive, highly efficient, advanced Class D amplifier design. It also features patented CDRS™ - Class D Ripple Suppression technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. The XPA 4002 is half the size of comparable amplifiers, conserving rack space and weighing only 9 lbs (4 kg). The Extron exclusive, high efficiency design generates very little heat and allows the amplifier to be convection cooled.

Energy Efficient Amplifier with Auto Power-Down

The XPA 4002 ENERGY STAR qualified amplifier is an energy efficient product that conserves energy and reduces costs. With an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, it consumes just 30 watts or less when idle and less than 1 watt in standby mode.

XPA 4002

The XPA 4002 two channel low impedance amplifier delivers 400 watts rms per channel into 4 ohms or 200 watts per channel into 8 ohms for program audio reinforcement. It features a bridged mode that provides a single 800 watt output into 8 ohms.

XPA 4002-70V

The XPA 4002-70V two channel amplifier delivers 400 watts rms per channel for 70 volt high impedance speaker systems in voice reinforcement and distributed audio applications.

Professional Integration Features

The XPA 4002 has an ultra low inrush current draw to prevent power circuit overload that occurs when multiple amplifiers are switched on simultaneously. This feature eliminates the need for power sequencing in systems with multiple amplifiers in large centralized equipment racks, and prevents other equipment from experiencing power interruption from associated power surges. The amplifier also features a very low thermal dissipation of 54 watts or 185 BTU/hr, under full load, to keep racks and equipment cabinets cool.

The XPA 4002 is housed in a compact 1U, full rack width enclosure. It accepts balanced and unbalanced input signals and includes recessed, detented level controls located on the rear panel to prevent tampering. These controls allow for adjusting audio system gain structure, or setting individual levels for each zone. Additionally, the XPA 4002 includes multiple protection circuits that momentarily activate when an abnormal condition, such as overheating, is detected. An advanced, automatic clip limiter protects speakers from clipping distortion.

Features

Inputs: Balanced or unbalanced on 3.5 mm, 3-pole captive screw connectors

Speaker Outputs: Screw-lock, 5 mm, 2-pole captive screw connectors

800 watts rms output power:
XPA 4002 - 2 x 400 watts @ 4 ohms, 2 x 200 watts @ 8 ohms, or 1 x 800 watts @ 8 ohms (bridged)
XPA 4002-70V - 2 x 400 watts @ 70 volts — The XPA 4002 is designed for use in large environments, for powering a large quantity of high impedance distributed speakers, high powered paging horns, or large speaker cabinets.

ENERGY STAR® qualified amplifier — The XPA 4002 is an ENERGY STAR qualified amplifier and energy efficient product that conserves energy and reduces costs.

Professional grade signal-to-noise and THD+N performance — The XPA 4002 delivers professional grade peformance with 100 dB signal-to-noise ratio and 0.1% THD+N.

Extron Patented CDRS™ - Class D Ripple Suppression — CDRS is an Extron Patented technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions which can interfere with sensitive AV equipment such as wireless microphones.

Convection cooled, fanless operation — The XPA 4002 does not require internal fans or vents for cooling, ensuring quiet, reliable operation. It generates substantially less heat than conventional power amplifiers, making it ideal for rack-mount applications.

Ultra low inrush current - no need for power sequencing — Allows multiple XTRA Series amplifiers to be powered on simultaneously without overloading power circuits. This eliminates the need for power sequencing.

Power factor correction - removes harmonic content on AC line — The XPA 4002 features power factor correction technology that smoothes out the high peak currents of the amplifier’s current draw, thus minimizing the presence of high frequency harmonics on the AC power line, and therefore preventing audible artifacts from being transmitted to other audio equipment in the system.

Rack-mountable 1U, full rack width enclosure — With the capability to deliver full-sized amplifier power in one half the size of many comparable power amplifiers, the XPA 4002 reduces rack space requirements for many installations.

Auto power-down with fast power-up — The XPA 4002 meets ENERGY STAR qualification requirements with an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, dramatically reducing power consumption. It quickly returns to full power status in less than one second upon signal detection.

Rear panel recessed, detented level controls — Provide attenuation of input signals for adjusting audio system gain staging as well as multi-zone applications. They are located on the rear panel to prevent users from tampering with level adjustments.

Automatic clip limiter — Detects actual onset of clipping by comparing input and output waveforms. Gain is automatically reduced without audible artifacts to protect speakers from clipping distortion.

Multiple protection circuits — Activate during output shorts, thermal overload, or DC faults to prevent damage to the amplifier and speakers.

Remote standby port — Enables the XPA 4002 to be remotely powered down when not in use, reducing operating cost.

High pass filter for high impedance models — This switch selectable filter, available on the 70 volt model, rolls off frequencies below 80 Hz to prevent saturation of speaker transformers.

Bridgeable output for low impedance model — The power output of the XPA 4002 4 ohm / 8 ohm model can be effectively doubled by bridging the output. When the bridging switch is engaged, a mono source is wired to input 1 while the output is wired for bridged operation. Bridging allows power to be output at 800 watts into 8 ohms or 400 watts into 16 ohms. The minimum load impedance when bridging is 8 ohms. See manual for complete wiring details.

5 mm screw-lock captive screw speaker connectors — Enable simple, secure connections with 22 to 12 AWG speaker cables.

Front and rear-mounted signal and protection indication LEDs — Provide convenient indication of input signal presence and protection circuit activation from both sides of an equipment rack.

Front panel over-temperature LED — Provides visual indication that the enclosure temperature has exceeded the optimal value, well in advance of the onset of thermal protection circuitry.

Internal Extron Everlast™ power supply — Provides worldwide power compatibility, with high‑demonstrated reliability and low power consumption for reduced operating cost

Extron Everlast Power Supply is covered by a 7‑year parts and labor warranty
