Pay attention to before use:

  1. Only DC power supply can be used.Ac transformer needs to be less than 48V after
  2. Audio electronic products pay attention to the reasonable combination of use, sothatitcan achieve the greatest value and auditory experience.Please choose a reasonable power supply and passive speaker before use.The output power variesaccording to the speaker impedance.The best match is 1.2-1.5:1 (that is, the speakerpower is Sow, and the amplifier power is 6oW-75w)
  3. Maximum power in power 48v, 4Q speakers, distortion of 10% when measuring theresulting power
  4. please check it before using: When you receive the machine and find that the audioinput and output interface knobs are relatively loose, Please tighten it manually by your self.
  5. Please use a good quality audio cable and power supply to avoid the distortion ofthe machine due to these.
  6. We will provide good customer service and warranty service for our brand products. For any questions, please contact our customer service team: [email protected]
AUX and RCA inputs cannot be connected to play at the same time
otherwise there will be crosstalk
