Most of you know what a microphone preamp or a phono preamp is and what it is used for. But the name: Audio Control Center (ACC) does not convey the same understanding. So, we are departing from our usual format of a separate data sheet and user guide.
The ACC data sheet is also the user guide because you need more information than just the number of inputs and outputs, gain and noise level. As important as these are, you also need to know what the unit does and how YOU can use it.
