Inter-M DPX-600S 1-Channel 600W Digital Power Amplifier

The Inter-M DPX-600S is a 1-channel 600W Class-D digital power amplifier, designed for professional installations that demand reliability, performance, and protection in a compact 1U chassis. Part of Inter-M’s advanced DPX Series, it combines high efficiency with robust fault detection to deliver clear, stable audio across distributed sound and PA systems.

With redundant AC/DC power operation, the DPX-600S ensures uninterrupted functionality even during power outages—seamlessly switching to DC 24V emergency backup power when required. This makes it particularly suitable for life-safety and emergency broadcasting systems where continuous operation is critical.

The DPX-600S features a comprehensive suite of protection functions, including safeguards against overheating, output short, over-input, reverse voltage, and ground fault. Visual and audible fault indication via front-panel LEDs and buzzer alert allows quick system diagnostics, minimising downtime and ensuring stable system operation.

Ideal for small-to-medium installations, the DPX-600S provides professional-grade performance for environments requiring dependable background music, paging, or emergency broadcast capability.

The DPX-600D offers dual 600W channels for flexible multi-zone or stereo applications, while the DPX-600S delivers a single 600W output in a compact 1U design, ideal for single-zone systems requiring powerful, reliable performance with identical protection and redundancy features.

Typical applications include:

• Retail and small franchise outlets

• Office buildings and corporate facilities

• Educational institutions and classrooms

• Hotels and hospitality environments

• Houses of worship

• Restaurants and cafes
