I am new to the digital recording and am having some issues connecting my AR16 USB mixer to my computer. My computer is a new IMac. It recognizes the AR 16 through the controller. I can also see it when I open Studio one and pro tools. When I push the USB option on the mixer i see my Mic signals and they are pretty loud. But, as soon as I hit record, the mic levels are non existant. Even when I turn the gain all the way up on the mixer, I get distortion and feedback. Then to add to the situation, when I try to playback what I recorded, the mixer does not produce any sound. I have to physically unplug the USB wire from my mixer and use the computer built in output to hear what I recorded. Any advice on something I am missing to set the gain levels while recording and being able to listen to playback through the mixer??
