Hi. I have M-Audio MicroTrack 24/96. And i need to bye couple condenser microphones to equipe it. There is some trouble. Phantom power of MicroTrack is just 30V only. But usual in portable recording devices (as i know) it equals 48V. I dont want use some pre-amplifier. Could you help me to choose condenser microphones with appropriate phantom power? (It needs to right properly(!!) with 30V only) Some notes: Cardioid or hyper-cardioid. Price <=$350. Matched pair (if it possible). My common recordings are upright and grand piano (in studio or small hall). Thanks. Ivan.
