The Extron XPA U 358C is a plenum-rated, Class D power amplifier featuring eight 35-watt channels for distributed audio systems. It delivers high-fidelity sound with 100 dB signal-to-noise ratio and supports both 4/8 ohm low-impedance and 70V/100V constant-voltage loads in a compact half-rack, 1U metal enclosure. Procure.ae supplies this audio equipment for businesses, schools, hospitals, and government buyers across the UAE.
This amplifier provides eight independent 35-watt channels with frequency response from 20 Hz to 20 kHz ±1 dB and THD + Noise of 0.1% at 1 kHz. It features power factor correction, ultra-low inrush current, and CDRS Class D Ripple Suppression for stable performance. Input connectors include four 3.5 mm captive screw terminals, while output uses four 5 mm screw-lock connectors. Protection includes clip limiting, thermal cutoff, and short circuit prevention with dedicated LEDs.
Designed for professional installations, the XPA U 358C operates on 100-240 VAC, 50-60 Hz power and is convection cooled without fans to reduce noise. It measures 43 mm H x 220 mm W x 267 mm D and weighs 1.9 kg, fitting a standard half-rack space with included mounting hardware. The unit supports control ports for system integration and operates in temperatures from 0°C to +50°C. Procure.ae offers bulk, project, and tender quotations for this equipment throughout the UAE and MEA.
