Why Choose This 4-Channel 350W Class D Amplifier?
Engineered with advanced Class D technology, this amplifier packs four 350W channels** into a compact 2U rack-mount chassis** (485×400×88mm), delivering **exceptional power density and energy efficiency** with minimal heat generation. The ability to switch between **100V constant voltage (perfect for distributed ceiling speaker systems) and **8Ω constant impedance** (ideal for traditional loudspeakers) makes it incredibly versatile for system integrators and installation contractors.

## Advanced Audio Features
- **Four balanced inputs** with **independent volume controls** per channel – giving you complete command over each zone's audio level.
- **Wide frequency response** (80Hz–20kHz ±1dB) delivers natural, accurate sound for both background music and clear voice paging.
- **Ultra-low THD** (≤0.1%) and **high signal-to-noise ratio** (≥80dB) ensure pristine, noise-free audio quality even at maximum output.
- **Line sensitivity and line output at 0dB** enable seamless integration with mixers, DSP units, and other source equipment.
- **350W per channel** provides ample headroom for dynamic content and high-SPL applications.

## Comprehensive Protection & Real-Time Monitoring
This amplifier features a **full protection circuit suite** that safeguards both the amplifier and connected speakers:
- **DC protection** – prevents speaker-damaging DC offsets
- **Overload protection** – limits output during excessive signal peaks
- **Over-temperature protection** – operates reliably from -5℃ to 80℃
- **Short-circuit protection** – instant response to output shorts
Front-panel **signal, clipping, overload, and protection indicators** provide real-time visual status. When input signals exceed safe levels, or when overload, overheating, or short-circuit conditions occur, the **protection indicators illuminate** – allowing immediate intervention to prevent system failure.
