Professional 2-Channel 350W Class D Power Amplifier – 100V & 8Ω Rack-Mount Audio Solution

Looking for a high-output 350W Class D power amplifier that combines raw power with precision control for demanding commercial and professional audio installations? Our 2-channel 350W digital power amplifier is built to drive both constant voltage (100V) and constant impedance (8Ω) speaker systems with ease, making it the ultimate choice for large-scale PA systems, warehouse paging, conference centers, houses of worship, sports facilities, and high-ceiling retail environments.

Why Choose This 350W Class D Amplifier?

Leveraging efficient Class D topology, this amplifier delivers 350W of clean, reliable power while maintaining compact 2U rack-mount dimensions (485×400×88mm) and minimal heat dissipation. It's the perfect workhorse for system integrators and installation contractors who need high headroom, stable performance, and long-term reliability in 24/7 operation environments. The dual-output capability (100V constant voltage / 8Ω constant impedance) gives you the freedom to design audio systems for distributed ceiling speakers, high-SPL horn speakers, or traditional passive loudspeakers – all with a single amplifier.

Advanced Audio Features

• Two balanced inputs with independent channel volume controls – enabling precise zone-level balancing and flexible system integration.

• Flat frequency response (80Hz–20kHz ±1dB) ensures natural, transparent sound reproduction for both music playback and vocal announcements.

• Ultra-low distortion (THD ≤0.1%) and high signal-to-noise ratio (≥80dB) deliver crystal-clear audio even at maximum output – no unwanted noise, no coloration.

• Line sensitivity and line output at 0dB allow seamless interfacing with digital mixers, audio processors, and DSP units.

• 350W output power per channel provides ample headroom for dynamic program material and high-SPL applications.

Comprehensive Protection System

This amplifier is equipped with a full suite of protection circuits to safeguard your investment and ensure uninterrupted operation:

• DC protection – prevents speaker damage from DC offset faults

• Overload protection – limits output during excessive signal peaks

• Over-temperature protection – automatically adjusts or shuts down under extreme heat (operating range: -5℃ to 80℃)

• Short-circuit protection – immediately responds to output shorts

Real-time front-panel signal, clipping, overload, and protection indicators give you instant visual feedback on amplifier status. When input signals exceed safe levels, or when overload, overheating, or short-circuit conditions occur, the protection indicators illuminate to alert you – allowing proactive intervention before system failure.
