Combined constant voltage power amplifier YD-2000V

1. Standard chassis design, 3U aluminum alloy panel, with an integrated handle and hanging ear design, suitable for cabinet or desktop installation. 2. Professional noise gate controls the output signal to ensure the muting of background music. 3. An MP3 master volume control knob for unified volume adjustment of MP3, and two-band parametric equalization control knobs for adjusting treble and bass to enhance sound quality. 4. Each channel’s input volume and microphone volume are independently controlled by adjustment knobs. 5. 6. Equipped with an MP3 player, it can play audio programs stored in U-disks and SD cards, with a maximum support of 32G, and features Bluetooth functionality. 7. Equipped with FM radio function, capable of receiving radio stations with frequencies ranging from 88- 108MHz 8.5 audio source inputs, including 3 standard line input interfaces and 2 standard microphone input interfaces. 9.1 channel audio source output, which can be looped to the audio input interface of the next power amplifier. 10. MIC1 has the highest priority. When signal input occurs, it is automatically muted, and the junction FET 11. It can control the volume of six zones separately, with six adjustable levels for each zone 12. 120V/240V constant voltage output, 4-16Ω constant resistance output, CH1-CH6 six-channel partitioned 120V constant voltage output. 13. Real-time indicator lights for working status, including 3 signal indicators, 1 protection indicator, 1 distortion indicator, and 1 power indicator. 14. Protection of the line safety work area ensures safe operation of the output load under any harsh conditions such as short circuits and overloads. 15. With a comprehensive temperature protection function, when the machine temperature rises, the temperature servo circuit will accelerate the fan, ensuring low operating noise. 16. Peak negative feedback protection can effectively protect the power amplifier when the signal experiences distortion, shock, or severe overvoltage of line voltage. 17. The integrated crossover tone compensation circuit corrects the high-frequency loss caused by the line- to-line transformer, resulting in a flat signal spectrum curve on the line voltage and a beautiful tone. 18. High-octave bass cut circuit adopts low-cut technology with tone compensation to remove ultra-low frequency components posing safety hazards without compromising sound quality, ensuring the safe operation of the boost system. 20.
