The PS604D is a versatile four-channel amplifier delivering a total of 600 watts, utilizing patented PowerShare technology to distribute power asymmetrically across all outputs. Each channel can deliver full power as needed, allowing greater design flexibility without having to size the amplifier solely for the largest zone. Its load-independent outputs allow any channel to be configured for low-impedance (4–8Ω) or high-impedance (70/100V) applications without bridging or jumpers.

With integrated Dante audio networking, the PS604D supports four digital input channels while also mixing onboard analog inputs via ControlSpace Designer software. The Dual Feedback Loop system continuously monitors and controls voltage and current delivered to each load, improving linearity, reducing distortion, and protecting loudspeakers. Through ControlSpace networking, the amplifier can be fully configured and integrated into larger systems, offering advanced loudspeaker processing such as nine-band parametric EQ, matrix mixing, crossover, delay, limiters, and more. An auto-standby mode further enhances energy efficiency.

The PS604D is ideal for performing arts venues, houses of worship, conference centers, retail stores, restaurants and bars, and hospitality venues requiring flexible, networked amplification.
