3. Internal circuit adopts full surface-mount technology, more stable performance and more aesthetic wiring;
4. PCB uses double-sided circuitry, with strong adhesion of components, more stable and reliable;
5. Uses D-class power amplifier circuit, low heat generation, powerful power;
6. 2-channel audio signal input, with independent volume adjustment function;
★ 7. 2-channel microphone signal input, with independent volume adjustment, among which 1 channel comes with 48V phantom power supply and has an independent image power supply switch, using a 6.5 dual-jack interface;
★ 8. 1-channel EMC strong priority signal input, the signal input from this interface takes priority over other audio signals;
9. Built-in 5.0 Bluetooth receiving module, the receiving distance in an open area can reach 10 meters;
10. Front panel 1 USB interface, supports lossless APE, FLAC, WMA, WAV, MP3 audio file formats playback, and has buttons for up and down tracks, pause/play, equalization, mode, etc. control;
11. Built-in FM radio, can automatically search for radio stations and save up to 30 stations;
12. Uses LCD liquid crystal display, touch function keys operation;
13. Supports all functions of the built-in player through infrared remote control operation;
★ 14. Each channel volume has independent adjustment function, high and low frequencies are independently adjustable, and there is a total volume adjustment;
15. 4 unit working status indicator lights (power, signal, distortion, protection);
★ 16. Uses wide-voltage switching power supply, AC 100~260V can work normally;
★ 17. Has DC 24V direct current power supply, can be used for emergency power supply, and can also be connected with dual power supplies simultaneously, AC input without power supply automatically switches to DC 24V power supply;
