Peavey 1200 Stereo is a professional mixer designed to handle sound reinforcement applications. It features transformer-balanced low impedance mic inputs and unbalanced high impedance line inputs. The mic input has a wide dynamic range and can accept input impedances of 150-600 Ohms. The line input has a very wide dynamic range and can accept the line outputs from tape machines or other devices, as well as being very suitable for use with conventional high impedance microphones.
