2. The rated output power: 500W (± 65V power supply, 4 ohm load, distortion 10%)
3. Efficiency:> = 90%
4. SNR: 90dB
5. The total harmonic distortion:
380W (± 65 power 4 ohm speaker, distortion <0.1%)
280W (± 65 power 8 ohm speaker, distortion <0.1%)
6. Frequency range: 20Hz-20KHz
7. Speaker: 4-8Ω
8. Voltage Magnification: 36 times
9. Input sensitivity 1.5V (RMS)
10. Output short circuit protection: Yes
11. That output DC bias protection speaker protection: Yes
12. Over-temperature protection: Yes, radiator FET temperature higher than 100 ° C, turn off the output!
13. Amplifier board size: length x width x height = 98x43x30mm
14. Weight: 95 g
Use precautions:
1. Rated supply voltage is ±65V, ±58—±70V range, do not over 70V! positive and negative do not pick wrong
2. Recommended power supply ±65V
3. Recommended 4-8Ω / 10-18inch speaker
4. Carefully check before electricity, ensure the wiring is correct.
