Help needed. 440 trouble

[Soniclife]

I had something similar in setting up my 440 for the first time on saturday, I got massive distortion from the right speaker (connected to the companion) and silence from the left. I turned of with the remote, double checked the link connections, the 2nd link cable might not have been 100% in, and then it was OK. It reported last fault on the companion as 'magic wire calibration error', or similar. I've put it down to user error for now.
