Overview

The 4-Channel SM Pro Audio Q-Pre Microphone Preamp is for budget-conscious studios, yet it also works well in live environments as well. With systems available at very low prices, the market size for digital audio interfaces and computer-based digital editing has increased in a massive way. One of the main problems with many of these systems is the input stage only consists of unbalanced line inputs or very low (or no mic pre) gain structure for the balanced input stage and the unavailability of phantom power.

The SM Pro Audio Q-Pre comes to the rescue with 4 mic preamps, balanced input, gain control from -20dB to +40dB, and phantom power switchable for channels 1/2 & 3/4 (in pairs). The Q-Pre preamp uses SM Pro Audio's well-established E-Series mic preamps, enhanced circuit design, and robust housing, which can be rack mounted on an optional rack tray.
