Bose PowerShare PS404D Adaptable Power Amplifier

The Bose PowerShare PS404D Adaptable Power Amplifier delivers outstanding audio performance and reliability with patented technologies inherited from the field-proven PowerMatch line — now with added flexibility.

Put the power where you need it. Using innovative PowerShare technology, the amp shares power across all output channels and delivers 400 watts for installed applications. This means you can distribute the total 400 watts asymmetrically across all outputs or use any individual output to deliver full power. And with support for both low- and high-impedance loads up to 100V, it’s easy to adapt PowerShare amplifiers to a wide range of applications. ControlSpace Designer software allows for Ethernet-based configuration and quick setup of external control options. With onboard Dante® audio networking, you have the flexibility to place PowerShare amplifiers away from source locations and closer to loudspeakers. This unique set of features and technologies makes PowerShare one of the most versatile, high-performance amplifiers available today.
