While I am typically able to troubleshoot my own technology problems, I am at a loss here. I have been recording for a couple of months, and I have a Presonus Audiobox USB connected to my MacBook with Logic and a CAD M179 condenser microphone. As of yesterday, the audio coming into the Macbook is very quiet, and the only way I can hear my vocals is to move the volume slider for a given track all the way up to +6.0. As of two days ago, I was had to turn down the vocals because they were too loud at zero. So, I'm not sure if something is broken or I'm just doing something wrong. Another thing I noticed is that through the headphones I have plugged into the rear of the Audiobox, I experience a lot more latency than I did previously. Instead of monitoring myself in real time, it's delayed by more than two seconds. Any help would be greatly appreciated, as I am not that experienced with audio hardware. Thanks in advance!
