Model Version Description Part #
XPA 4002 Two Channel Amp - 400 Watts/Ch 60-1244-01
XPA 4002-70V 70 V Two Channel Amp - 400 Watts/Ch 60-1245-01

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.
