Help with my Yamaha DSP-AX640SE


Standard Member
Hi there,

I need a little help with my Yamaha DSP-AX640SE.

Two things; firstly I can't get the opitical out to work at the back. The front is currently working fine with my PS3 but I'm trying to run my SKY HD throught the back with no sound at all, but if I plug it in the front bingo, all working fine. Is there a setting I need to change to get this to work? Or could it just be faulty?

Secondly I'd like to know if there is a way to reset the amp as I've faffed about with so many things now I'd like to back to factory settings and do one thing at a time.

Your help and advise is apprecaited.
