I wonder if anyone can help me. I have an m3700 desk that was working fine. I haven't powered it up for a couple of weeks until tonight, and I can't get any output from it. It makes no diference if I come from the tape or inputs on the desk. I get nothing on either the individual channels or the VU meters. The lcd display reads "mutes and faders" as usual with no error message. Has anyone else had this problem? Is there something really stupid that I'm missing? I have switched off and back on again to see if it reset something. Any help most appreciated or ideas from other owners. I was due to start recording tomorrow too! Dave.
