Adaptable PowerShare Technology

The PS404D features patented Bose PowerShare technology, allowing the total 400 watts of power to be shared asymmetrically across all four outputs. This provides incredible flexibility, enabling you to allocate power precisely where it's needed without being constrained by the fixed power-per-channel limitations of traditional amplifiers.

Integrated Dante Audio Networking

Seamlessly integrate the PS404D into larger networked audio systems with its built-in Dante connectivity. Receive up to four channels of high-quality, low-latency digital audio over a standard Ethernet network, simplifying wiring and enhancing system scalability.

Advanced DSP and Control

Take full command of your sound with onboard DSP configured via Bose ControlSpace Designer software. Access a suite of tools including a 9-band PEQ, matrix mixer, crossovers, limiters, and delay to optimize loudspeaker performance and tailor the audio to any environment, all without external processors.
