i bought my desk about six weeks ago, upgrading from a mix wizard. 3 wks ago i did a wedding for my friend, just his guitar and 1 vocal mic. everything was great, had done 3 songs and all i was doing was killing the reverb inbetween songs by using an asigned soft key on my ipad. Half way through the the 4th song, without touching anything the reverb just took off and the volume got louder and louder. It ended up taking out 3 speaker drivers and i ended up having to get by with just a spare monitor.

Then just this week, at the beginning of a gig the desk just suddenly started creating white noise as soon as i started to play music on my phone which was plugged into ch15 & 16.

I’ve spoken to A&H and the desk is now away being looked at but their initial thoughts are a fault on the DSP board.
