The IMP-612 A is a professional mixer preamplifier for general public address applications with two separate outputs and seven inputs. The volume and the sound can be controlled separately for each output.

The IMP-612 A has six line inputs (cinch / 3.5 mm jack / clamp) and a microphone input (XLR). All signals can be mixed together using an input potentiometer.
