Troubleshooting Behringer DX2000 USB failed output channel
Channel: Michael Brooks

Behringer are well known for their dubious quality control and poor durability of mixers.

The DX2000 is prone to developing a fault where it loses the right or left main output channel.

A common cause is the ribbon cable between the mixing PCB and the input/output PCB.

I couldn't find any videos on how to open this mixer so I thought I'd share my findings.

UPDATE: I've had a couple of people tell me that the ribbon cable cores can sometimes have internal fractures, and that replacing the entire ribbon was the cure. Others have been able to cure it by resoldering the connector, or reseating the cable in its connector. YMMV!


DISCLAIMER: check your warranty first. Many Behringer mixers have a 3 year warranty. If it's in warranty, just send it to Behringer to fix. I'm not responsible if you void your warranty or break your mixer!

DISCLAIMER: Risk of electric shock if you open the equipment while powered / live. Disconnect from mains before opening. If you decide to work live, this is obviously at your own risk and I recommend powering the mixer via an RCD. The metal casing of the Behringer is grounded via the mains plug earth pin, so you should assume you will be in contact with ground when working on this mixer.
