The PS404D is a four-channel amplifier delivering 400 watts of total power with patented PowerShare technology, allowing flexible, asymmetrical power distribution across all outputs. Each channel can deliver full power as needed, giving greater design flexibility without oversizing for the largest zone.

Its load-independent outputs support both low-impedance (4–8Ω) and high-impedance (70/100V) systems without bridging or jumpers. With integrated Dante audio networking, it supports four digital input channels and can mix analog and Dante inputs via ControlSpace Designer software.

The Dual Feedback Loop system continuously monitors voltage and current to improve performance, reduce distortion, and protect loudspeakers. Through ControlSpace networking, users gain advanced processing features including nine-band parametric EQ, matrix mixing, crossover, delay, limiters, and more. An auto-standby mode improves energy efficiency.

The PS404D is ideal for performing arts venues, houses of worship, conference centers, retail stores, restaurants, bars, and hospitality spaces requiring flexible, networked amplification.
