Please check whether all cables are right connected and the connection is firm.
Please check whether the settings of DSP and LEVEL are in the normal working position.

sound source device, or increase the output LEVEL with the LEVEL controller.
Check whether the sound source input is normal.
Check whether the cable is bent, short circuit or broken.
Check whether the signal connecting wire is in good connection.
If the signal indicator is in red for long time, it means that the output volume is too
