Lake People F355-A

Dual-Channel Microphone Preamplifier with Class A Input Stages

The Lake People F355-A is a dual-channel microphone preamplifier designed for professional audio environments where both technical precision and characterful signal reproduction are essential. Based on the F355 model, the F355-A is equipped with Class A input stages, providing a tonal character with added warmth and fullness, particularly in the midrange.

Class A Input Stages

Unlike the F355, the F355-A features Class A input stages, which deliver a richer and more dynamic sound. This circuit design is especially well-suited for recording vocals and acoustic instruments.

Two Independent Channels

The F355-A offers two independent microphone channels with individual gain controls. With up to +66 dB of gain and 12-step incremental adjustment, the unit allows precise and repeatable settings suitable for professional workflows.

High Signal Integrity

Balanced XLR inputs and outputs ensure low noise, high interference immunity, and excellent headroom. The preamp also includes features such as variable low-cut filter, pad, 48 V phantom power, and phase inversion. A 16-step level meter provides clear visual feedback during adjustments.

Durable Construction

Housed in a 1U rackmount format, the F355-A is built to withstand the demands of studio, broadcast, and live production environments. The chassis is designed for long-term reliability in professional use.
