Happy Jack Posted April 20, 2010 Share Posted April 20, 2010 Just picked up a cheap old desk, an Alesis 1622, for faffing about in the rehearsal room. In order to get any useable volume from the XLR mic inputs, I have to turn the gain WAY up high on each channel. DI'd instruments have no such problem, so presumably this is a mic level / line level issue? I didn't realise there were ANY more-or-less modern desks (i.e. 1990's or later) without pre-amps for the mic level inputs. Am I missing something really obvious?

Have you followedthe level setting procedure in the manual? Also the main out can be switched between +4 dbV or -10dbV. Quote Link to comment Share on other sites More sharing options...

Are you connecting the instruments to the jacks on the rear? These are much higher impedance which is correct. Looks pretty normal to me.
