The ARC-MIC-PRE is a 2 channel mic preamp that can be directly connected to your balanced RJ45 console line inputs. This converts two of your line inputs into mic level inputs. The ARC-MIC-PRE is ideal for the ARC-5, ARC-8 and ARC-10 series console. It is a cost effective way to give you up to two additional mic inputs for your console. Using RJ45 ethernet outputs, the ARC-MIC-PRE can connect directly to a balanced RJ45 input on your console.
