Description
The Lake People F311-D 2-channel microphone preamplifier is designed for studio and location recording, bypassing subpar mixing console preamps, or direct-to-tape applications. With ultra-low inherent noise, precise step-switched gain control, and a wide, flat frequency response, the F311-D delivers exceptional audio fidelity and operational consistency. Phantom power, lo-cut filtering, and phase reversal provide versatility for professional recording scenarios, while both balanced XLR and unbalanced RCA outputs ensure compatibility with a wide range of setups. Built for reliability, the F311-D is equally at home in fixed installations and demanding mobile recording environments.
