Applicable to our A1, A1-MR, A2+, HD3, HD4, A5+, and HD6 speaker models
If one of your speakers is not working (whether it be the left or right speaker), we would recommend the following troubleshooting steps:
Start by power cycling your speakers by turning them off and then back on. From there:
- Check to make sure the speaker wire connecting the left and right speakers is connected according to proper polarity (Red to Gold, Black to Silver) on both ends.
- Please make sure all of your connector cables are in working order. Try different cables as well as a different source device.
- If you are using any other devices in line with these speakers, please temporarily remove them from your setup and connect the source directly to the speakers
- Please try using each available input, one at a time, to see how the speakers react. When testing via RCA swap the RCA jacks (red to white and white to red) to see if the issue remains in the same channel.
