Introducing the extraordinary 2BA-221 Mic and Line Module, featuring our remarkable continuously variable impedance microphone preamp. With microphone level, line level, and Hi-Z instrument inputs, the 2BA-221 utilizes separate and individually controlled solid state input controls to mix the microphone input with the Hi-Z or line input into the variable vacuum tube output. Using the variable mic impedance and variable solid state and tube stages gives you unprecedented sonic control of anything you throw at it, be it mic level, line level, or instrument level.
