Product Introduction:
1.Power Supply Voltage:defaults double AC 18V/3A,power more than 60W (the maximum voltage should
  be no more than double AC 19V,and it should be no less than 18V;or the digital tube will be off,
  and the voice will get distorted;if you want to use AC 12V,you need to modify lamp filament buck
  resistance 2.2 ohm;then the amplifier output power will be relatively low).
2.Headphone amplifier/pre-output:amplification times is 0.8
3.Im1875t amplifier output power:typical 20W (max 30W)
4.Loudspeaker impedance:4-8 ohm
5.Total harmonic distortion:<0.04%
6.Signal noise ratio:105dB
7.Frequency response:14Hz-100KHz
