The Extron XTRA™ Series XPA 2004 is a 1U, convection cooled power amplifier delivering four channels of 200 watts into 4 ohms or 100 watts into 8 ohms. This professional grade amplifier features a 100 dB signal-to-noise ratio with 0.1% THD+N. The XPA 2004 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 2004 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.
The XPA 2004 four channel amplifier delivers 200 watts rms per channel into 4 ohms or 100 watts rms per channel into 8 ohms for amplification of voice or program audio content to stereo speakers, four sets of 8 ohm ceiling speakers in a four zone application, or as part of a surround sound system using the Extron SSP 7.1 Surround Sound Processor. It features a bridged mode that provides two channels of 400 watts output into 8 ohms.
The XPA 2004 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 2004 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.
