Four-channel microphone preamplifier for professional audio recording

The Lake People MIC-AMP F311 Q is a four-channel microphone preamplifier designed for studio and live sound applications. It offers transparent gain with low noise and high detail reproduction when recording vocals, instruments, or ambient sound.

Four independent microphone channels

The F311 Q is equipped with four separate preamp channels. Each channel provides individual gain control up to +66 dB, allowing precise adjustment for different microphone types and signal sources.

Transparent signal processing

Balanced XLR inputs ensure strong noise rejection and stable signal transmission. The frequency range extends from 5 Hz to 70 kHz, and the unit delivers low total harmonic distortion along with a high signal-to-noise ratio.

Integration and features

Designed in a 1U rack format, the unit integrates easily into fixed or mobile setups. Each channel includes features such as a low-cut filter, 48 V phantom power, phase inversion, and a four-step level indicator for flexible use in various audio environments.
