Power Amplifiers XPA U 3502 Extron

Power Amplifier XPA U 3502

The Extron XPA U 3502 is a high-power audio amplifier, ENERGY STAR® qualified, delivering two channels of 350W at 8Ω or 4Ω. With a compact half-rack, 1U design and fanless convection cooling, it saves installation space and reduces energy consumption.

The XPA U 3502 utilizes advanced Class D amplification technology with Power Factor Correction (PFC) to minimize electrical noise and optimize efficiency. The InstaWake™ feature allows the device to exit standby mode in less than 100 milliseconds without audio interruption. Additionally, Extron’s patented CDRS™ (Class D Ripple Suppression) technology ensures clean, smooth audio signals by reducing noise and distortion.

With up to 28% cooler operation and greater energy efficiency compared to traditional amplifiers, the XPA U 3502 is an ideal choice for professional audio systems in meeting rooms, lecture halls, conference centers, and other commercial applications.
