HUAIN PA System Public Address Pre-Power 6-Zone Front Power Amplifier (560W) HY-GF56

1. Product Description: Standard chassis design, 2U aluminum alloy panel, integrated handle and ear mount design, detachable from the panel, suitable for cabinet or desktop installation. Professional noise gate controls output signal to suppress background music. Intelligent power management function automatically enters standby mode when no signal is present, with standby power consumption less than 3W, ensuring 24/7 uninterrupted operation. A master volume control knob controls all line and microphone volume, and two-band parametric EQ knobs adjust bass and treble for improved sound quality.

3. Independent volume control knobs for each line input and each microphone channel.

4. MP3 playback on/off buttons: Includes Bluetooth, radio, USB/SD card playback, and a small screen to display playback information. Playback status; MP3 player capable of playing audio from USB flash drives and SD cards up to 32GB;

5. FM radio capable of receiving radio stations from 88-108MHz; 6 audio inputs, including 3 standard line inputs and 3 standard microphone inputs;

6. 1-channel audio output, loopable to the next amplifier's audio input; MIC3 has the highest priority, automatically muting when input signal is present. Junction FETs perform priority switching to ensure signal distortion during muting;

7. 6-channel zone switches and indicators; zone indicator lights illuminate when a zone is enabled;

8. 70V and 100V constant-voltage outputs, 4-16Ω constant-resistance outputs, six zones (CH1-CH6) with constant voltage. Output;

9. Real-time operating status indicators: 5 signal indicators, 1 protection indicator, 1 distortion indicator, and 1 power indicator;

10. Line safe operating area protection ensures safe operation of the output load in any harsh environment, including short circuits and overloads;

11. Comprehensive temperature protection: When the unit temperature rises, the temperature servo circuit accelerates the fan, ensuring low fan noise; Peak negative feedback protection effectively protects the amplifier when signal distortion, surges, or severe line voltage overvoltage occurs;

12. Integrated cross-tone compensation circuit corrects high-frequency losses caused by line transformers, ensuring a smooth signal spectrum on the line voltage with beautiful sound quality;

13. High-octave bass cut circuit with tone compensation Low-cut technology removes potentially hazardous ultra-low frequency components without sacrificing sound quality, ensuring safe operation of the boost system.
