Extron XPA U 358 Class D Power Amplifier

The Extron XPA U 358 is an eight-channel Class D power amplifier designed for professional audio installations. It delivers 35 watts per channel into 4-ohm or 8-ohm loads within a fanless, plenum-rated half-rack enclosure. Procure.ae supplies this unit to businesses and government buyers across the UAE.

This eight-channel amplifier provides 35 watts of power per channel with frequency response from 20 Hz to 20 kHz ±1 dB. It features a signal-to-noise ratio of 100 dB and total harmonic distortion plus noise of 0.1% at 1 kHz. The unit accepts balanced or unbalanced audio inputs via four 3.5 mm captive screw connectors with +4 dBu nominal level.

Installation is simplified by its fanless, convection-cooled design housed in a plenum-rated half-rack enclosure. It includes CDRS Class D Ripple Suppression technology, clip limiting, thermal, short circuit, and DC output protection. The internal power supply operates on 100-240 VAC at 50-60 Hz with power factor correction.
