Maximize the Performance of Your Ribbon and Dynamic Mics If you want to maximize the performance of your ribbon and dynamic microphones, an in-line mic preamplifier like the ART Dual RP is a necessity. This 2-channel, phantom-powered unit yields up to +20dB of gain to bolster your existing preamp. You also get variable impedance controls for tailoring the load on your mics.
