Question

Two channels on my 2014 Presonus 16.0.2 mixer have developed a buzz/white noise. It started with one channel about a year ago, and the same problem just started happening with another channel. The signal from a microphone plugged into one of these channels is much diminished, but slightly audible. When turned all the way down, the input meter still reads about 20% on each channel. Have the pre-amps on these channels gone bad? How can I fix this? Thanks!

To enriqueperibanez: It seems that there is indeed an issue with the preamps. The options were to send the mixer to PreSonus for repair, (and pay shipping/handling/parts, not cheap) or figure something else out. I ended up finding another mixer, and keeping both. I no longer use the old one in live settings, but do some home recording with it. Hope that helps!
