Recording a guitar into a mixer via an Acoustic Image Clarus preamp out, and out to a video camera. The problem is that the guitarist often adjusts his volume during playing, and that can mess up my signal level going into the camera. Other situation is when he plays chord melody, the signal is pretty weak. Someone told me that a compressor/limiter would solve this problem, such as the Presonus Comp16. I know nothing about these units, or any other units for that matter, and just trying to solve this volume problem. Will it help, or should I be looking for something else? I don't know if it has to do with the problem, but I always have to normalize the audio after I drop it into the computer because it sounds so weak and lifeless. Any suggestions are appreciated.
