Specifications
- Use voltage range: DC ± 30 to ± 80V (when the supply voltage is less than ± 30V, two 3K / 3W resistors need to be replaced by 1.5K / 3W resistors) It is recommended to use AC voltage below 52V, because the mains voltage will fluctuate, Point margin Caixing.
- Maximum output power: 350W / 8Ω distortion <0.1%
- (± 85V power supply) 700W / 4Ω distortion <0.1%
- (± 70V power supply) 900W / 2Ω distortion <1%
- Overvoltage protection: ± 85V
- Overheat protection: 85 ° C
- Voltage magnification: 33 times
- Input Sensitivity: 1.5V (rms)
- Input impedance: 6KΩ
- Frequency response: 0-50KHz ± 3dB 10W / 8Ω
- Residual noise voltage: 200uV
- Dynamic range:> 100dB
- Efficiency: Class D amplifier efficiency is very high, of course, when the output power of different efficiency, high efficiency, high efficiency, 200W / 8Ω output to 90% or more.
- Distortion (THD + N):
