Strange Line Preamp Behaviour UC Surface & Studiolive III 32R
Posted: Wed Feb 05, 2020 8:06 am
Hello folks,
I have recently bought a Presonus Studiolive III 32R digital mixer and have been using this for a few weeks now.
Last night I came across a strange issue where the stereo balance was off on one side of a stereo pair of line inputs. After playing around for a while to get to the bottom of it and isolate the issue I found that the gain control on one of the pair was not actually changing the gain. This could be clearly heard and seen on the meter when adjusting the control and then doing the same on the correctly functioning partner input of the pair. I updated the firmware again although I was already using the latest firmware and also did a few power cycles and the same issue cropped up on the same channel. Suspecting the preamp on that channel (8) I plugged in a mic and the preamp gain control worked fine.
I then reset all of the ins and outs and routing on the digital mixer screen and the stereo pair started behaving as expected again. As soon as I start routing the inputs to the channels in the order that I want however, the issue reappears. I went around this loop twice and the same thing happened.
is this a known bug with UC Surface? I haven't had time to test all channels but at the moment I suspect that if I engage input to channel routing that isn't 1 for 1 that I loose control of the gain for the line input on one side of the stereo pair, it defaults to zero regardless of what I do with the control and the figure it displays.
Alternatively is there something silly that I might be missing?
Many thanks in advance!
Carl.
P.S. I have raised a ticket for the above but thought an experienced user might put kindly me right in this forum.
