The Bose PowerShare PS404D is a 4‑channel, 400 W power‑sharing amplifier built for flexible installed audio. Its PowerShare architecture intelligently allocates the full 400 W asymmetrically across any output, so each zone or loudspeaker gets exactly the power it needs without changing hardware. Each channel supports both low‑impedance (4–8 Ω) and high‑impedance (70/100 V) operation with no bridging or jumpers, streamlining specification and deployment.
Integrated Dante networking adds four network audio inputs, and the onboard mixer lets you combine analogue and Dante sources via Bose ControlSpace Designer. Dual feedback loop technology—derived from PowerMatch—monitors current and voltage to improve linearity, reduce distortion and protect connected loudspeakers. Comprehensive DSP includes 9‑band PEQ, matrix mixing, crossovers, limiters, delay, mute and polarity, while auto‑standby reduces energy use between events.
Compact, robust and network‑ready, the PS404D delivers clean, dependable power with precise control for professional installations. Ideal for meeting rooms, lecture theatres, hospitality venues and houses of worship.
