Hi Scott, Yes, the balanced input on the back can be used for a microphone input or as a balance line input. The input has a gain range from -12 dB to +35.25 dB in 0.75 dB steps. The maximum input level is 1.0 Vrms (2.83Vpp). The analog input impedance ranges from ~3k Ohms at maximum gain to 54k Ohms at 0 dB gain.
