After a long hiatus I am attempting to setup up my iDr48/T112. The last time I used this mixer it was working fine. Now however, I am unable to get the Preamp meters to work. A mic check shows metering on the input channel strip, and routing to main outputs shows meter levels, so I am getting a signal. However, I’m seeing no meter on the preamp. The red LED indicator for preamp level is working. Is there something I’m missing that would cause the preamp audio level meter to not function?
Perhaps an issue with the audio level LED driver in the preamp meter circuit?
Any ideas?
