Bose PowerShareX PSX Series Amplifiers

Product Overview

The PowerShareX adaptable amplifiers are the perfect complement to Bose Professional sound systems. Integrated DSP provides instant access to optimized speaker presets, and ControlSpace Designer software allows for quick configuration. Proven Powersoft technology ensures maximum efficiency. Choose from three models: PSX1204D, PSX2404D, and PSX4804D. Each 1RU, networkable, four-channel amplifier offers innovative shared power flexibility, maximum power capacity, Dante® connectivity, and more, all in a space-saving design.

Easy integration with Bose Professional DSPs, loudspeakers, and the entire ControlSpace ecosystem simplifies design, configuration, installation, and operation.
