Locomotive Audio's dual channel 286A offers a huge sonic palette for engineers and producers to explore. Its single-ended Class A tube signal path is what makes this preamplifier so special. Inspired by the great vintage Ampex 601 vacuum tube tape recorder, the 286A features two tubes per channel, one EF806 and one 12AY7. The 286A can play nice by acting clean and natural with gentle even-order harmonics for a smooth, sweet touch. Get more aggressive with the "Gain" knob and drive the first 12AY7 stage for a warm and colored thickening effect. Go all-out and slam the final 12AY7 stage and output transformer through the "Level" knob for a fully-driven, saturated tube amp sound! Clean and natural to overdriven and fuzzy warm; your choice!

Locomotive Audio's single channel 14B compressor and limiter is based on a very old, but still very exciting concept of rebiasing the input tube with a sidechain control voltage. After all, some of the most famous compressors in history, such as the Fairchild 670, Gates Sta-Level and Collins 26U, employed this very technique. The results are a sound that cannot be replicated with other ways of gain reduction. The Locomotive Audio 14B and its added modern features allow it to achieve a unique sound in its own right. Starting with the semi-remote cutoff 6BC8 tube, a 12AY7 then drives two powerful push-pull 6V6 output tubes. The 14B is quite a versatile unit, with the ability to run soft and gentle or hard and aggressive. A sidechain low cut control offers even more flexibility, especially when used on the mixbus and linked with another 14B. This versatile unit can be used on all kinds of source material including vocals, drums, guitars, bass, piano and horns. With its high quality Cinemag input and interstage transformers, the 14B has the ability to define mid-range clutter and control the peaks at the same time. The user will notice an enhancement on any material run through this unit, even when not compressing.
