Hi guys. I own a Urei/Soundcraft 1620LE. I recently loaned it to a close friend for a party he was throwing. I was also playing at this party and when I arrived for my set I found the the mixer(House Out) was turned up to 10(max output) and both phono faders in use were also up to max(10). When I got the mixer back and tested it I found the that everything seemed "looser". Where I had plenty of volume/headroom before I now find that I must turn the master out waaay up to get the same kind of volume. Any ideas/advise is welcome. Thanks in advance.
