John Hardy MPC-600 Mic Preamp Card: Superior Replacement for MCI 600-Series Pr
A superior plug-in replacement for MCI 600-series console mic preamps. The MPC-600 drastically improves performance by using a combination of the John Hardy 16C mic input transformer (Jensen's best mic input model), the 990C discrete class-A op-amp, and the total absence of coupling capacitors in the signal path. Just plug it in!
