  If the power indicator is on but you're not getting any sound from your Cayin Amplifier, there are a few things you can check: * Ensure that mute is off. If the mute LED is lit, press the output button on the front panel so the operate button lights up. * Verify that your sound source is functioning correctly. * Confirm that the input selection is correct and switched to the appropriate input.

  If the power indicator on your Cayin Amplifier is off, try the following: * Make sure the power cord is securely connected to both the amplifier and the power outlet. * Check the main fuse and replace it with the same type and value if it's blown. * If the above steps don't resolve the issue, it may be due to internal problems. Please contact your local dealer or Cayin directly.

Why does my Cayin CS-6 PH have noise output?
- P
  Peter RodriguezAug 20, 2025
  Noise output from your Cayin Amplifier can be due to a couple of reasons: * The ground of the input signal cable may be open, or the cable's contact might be poor. Try replacing the input signal cable with a new one. * Alternatively, there may be issues with internal components or circuits. In this case, contact local agents or our company for assistance.
