Mô tả sản phẩm
Network PA System – Integrated Power Amplifier (2U, Class D, 70V/100V/4‑16Ω)Features:- High‑grade aluminum 2U black anodized brushed panel, beautiful and elegant.
- All internal PCBs adopt double‑sided SMT chip circuits for more stable and reliable performance.
- Adopts internationally advanced Class D digital power amplifier circuit, featuring high efficiency and energy saving.
- Output adopts isolated audio transformer, effectively enhancing load capacity and ensuring more stable and reliable use.
- 5‑channel signal input (3 microphone, 2 line).
- 1‑channel auxiliary signal output, which can be used to connect the next power amplifier.
- Equipped with 100V/70V constant voltage output and 4‑16Ω constant impedance output.
- Master volume adjustment function, independent volume adjustment for each input channel.
- Independent treble and bass adjustment.
- Volume potentiometer adopts fully sealed dust‑proof process, permanently dust‑proof with noise‑free adjustment.
- Internal signals adopt balanced signal circuit, with strong anti‑interference and lower noise.
- MIC1 automatic mute with adjustment switch, adjustable range: 0 to -30dB.
- 5‑unit LED level display with clear dynamic indication.
- Equipped with comprehensive protection functions: output short‑circuit protection, DC protection, overload protection, over‑temperature protection, etc.
- Cooling fan adopts automatic speed regulation design: lower temperature leads to slower speed, effectively reducing standby operating noise.This **Network PA System** integrated amplifier combines advanced Class D efficiency with versatile input mixing and robust protection for professional public address.In summary, this **Network PA System** 2U integrated power amplifier with multiple inputs, constant voltage/impedance outputs, and comprehensive protection is the ideal choice for schools, hotels, factories, and commercial buildings requiring a reliable, all‑in‑one PA solution.
