1. Confirm the volume on both the CPA Series loudspeaker and your audio source (e.g., smartphone, computer) is turned up.

*You can turn up volume through INPUT Gain or Bluetooth Knob on the rear panel of the CPA Series.*

2. Connect the speaker/headphone to different audio sources (e.g., smartphone, computer) to rule out issues with the source device.

3. Use different audio cables to test if a cable is faulty.

4. Ensure the audio source device or the microphone/instrument input is actively playing audio.
‍

*As many problems are frequently identified as NTF (No-Trouble-Found) and can be resolved through a few additional checks, we recommend that when you encounter any issues, always double-check all cable connections, the functionality of the power cord/power socket, the volume control level on the CPA loudspeakers, or the input source gear, etc.
