What is it?A 1U, convection-cooled 2-channel power amplifier. DetailsThe XPA 2002 delivers 200W RMS per channel into 4 ohms, 100W per channel into 8 ohms or 400W output into 8 ohms in bridge mode. It offers 100dB signal-to-noise ratio at 0.1% THD+N from a Class D amplifier design incorporating Extron’s patented CDRS - Class D Ripple Suppression technology said to provide a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. This “high efficiency” design is said to generate very little heat and allows the amplifier to be convection cooled.An auto power-down feature automatically puts the amplifier into standby after 25 minutes of inactivity. The Energy Star design consumes <23W of power when idle and <1W in standby mode. It also features a low inrush current draw to prevent power circuit overload when multiple amplifiers are switched on simultaneously. This feature eliminates the need for power sequencing to be built into systems designed with multiple amplifiers in large centralised equipment racks and prevents other equipment experiencing interruption from associated power surges. Extron has also developed the XPA 2002-70V – an alternative version of the amplifier delivering 200W RMS per channel for high-impedance speaker systems in voice reinforcement and distributed audio applications.
