many thanks to the person who replied to my response. rather cutting I think. do forgive me though. my experience with behringer has been good so far and I have not found any distortion on my mx series or errors. its been a great tool so far and shall always be. its part of my sonar 4 custom solution and the spec for the PC is just the way I want it, I'm not paying stupid money for a mackie 24 channel desk which I've already worked on which can have several faults and for someone who has a sight impairment or someone fully sighted to look at the master meter bridge. paying an extra £300 or so for it is rediculous. the behringer does its job proud and I love her to bits. its all to do with what you do with the mixer and how you want to achieve the sound via sonar and not the desk! lew
