HUAIN Digital Amplifier Conference Audio System HY-A420 HY-A430 HY-A440 HY-A460 HY-A480 HY-A4100 4x200W Professional Power Amplifier

1. Fully balanced, ultra-dynamic re-drive technology delivers smooth sound even under heavy loads.
2. 4×200W/8Ω, 4×400W/4Ω, and 2×400W/8Ω bridged into various impedances.
3. High signal-to-noise ratio and extremely low noise.
4. ★ LED indicators for signal and clipping status monitor the amplifier's operating status.
5. Fully automatic protection circuitry, including DC, overcurrent, overvoltage, overtemperature, and dynamic automatic limiting, ensures stable and efficient operation.
6. High-power thermal control for low noise. A self-regulating dual-speed fan effectively reduces internal temperature and improves system reliability.
7. Three classic operating modes: stereo, mono, and bridge, to accommodate various system configurations.
8. Dual XLR inputs and two output options: Speakon and red and black binding posts for enhanced compatibility.
9. Frequency response: 20Hz-20kHz.
10. Input impedance: 10kΩ (unbalanced), 20kΩ (balanced).
11. Damping factor >300 @ 8Ω.
12. Total harmonic distortion ≤0.01%.
