ANAHEIM, Calif. — Extron Electronics recently introduced the Extron XTRA Series XPA 1002-70V and XPA 1002-100V, half rack 1U, convection-cooled audio power amplifiers delivering two channels of 100 watts rms for 70 volt and 100 volt distributed speakers. These professional-grade amplifiers feature a 100 dB signal-to-noise ratio with 0.1% THD+N specifications.
The XPA 1002-70V and XPA 1002-100V are Energy Star qualified products with an efficient Class D amplifier design. They also feature patented CDRS – Class D ripple suppression technology that provides a clean audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. The XPA 1002-70V and XPA 1002-100V are housed in half-rack-width metal enclosures, conserving rack space and weighing only 2.5 lbs (1.1 kg). The high-efficiency design generates very little heat and allows the amplifiers to be convection cooled.
“These new XTRA series amplifiers deliver ample power in a small enclosure to easily boost amplifier channel counts two at a time, while only using half a rack width of space with each pair of channels added,” said Casey Hall, vice president of sales and marketing for Extron. “These amplifiers deliver 100 watts of power into a 70 volt or 100 volt line for powering high-impedance distributed speakers, making them ideal for supporting multi-zone applications such as presentation spaces or divisible rooms.”
The XPA 1002-70V and XPA 1002-100V amplifiers include an auto power-down feature that automatically places the amplifier into standby after a period of inactivity, and consumes just 10 watts when idle and less than 1 watt in standby mode. Each amplifier also 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.
