API 3124MV 4-Channel Microphone/Line Pre + Stereo Mixer

The API 3124MV is a 4-channel mic/line preamp that builds on the power of the 3124V, adding a stereo audio mixer with per-channel panning, aux sends, and stereo returns, turning the 3124MV into a veritable powerhouse for tracking and mixing. Housed in the same, fully-discrete circuitry used in all API preamps, each channel sends to the main mix while retaining its individual outputs, as well as all the channel controls from the 3124V, including: -20dB pads, 48V phantom power, switchable phase, high-impedance switches, 3:1/1:3 transformer tap selection, and mic/line inputs for balanced or unbalanced sources.

When you factor in the 3124MV's per-channel pan, aux send, and tip-ring insert jacks, as well as its master aux send, return, and left/right level controls, you might be wondering if the 3124MV is too good to be true, but the specifications and feature set speak for themselves—this is a 4-channel preamp unlike any other.
