Product information "Locomotive 14B PCB (Matched Pair)"
The Locomotive Audio 14B is a Vari-Mu compressor designed to give vocals perfect presence and smoothness. Inspired by classic vintage units such as the Gates Sta-Level, UA 175B, RCA BA-6A, and Collins 26U, it delivers authentic tube compression that cannot be replicated by any other method. Built with a printed circuit board, custom MuMetal-shielded transformers, and a backlit VU meter, the 14B offers precise control and the legendary warmth of vintage Vari-Mu circuitry.
