Description

The BC5000 BIGFOOT Optical Compressor from Burl Audio brings musicality, depth, and precision to any part of your audio signal chain, from tracking to final mastering. It features an optical compression core that delivers smooth, natural dynamics, supported by a fully discrete, class-A circuit design. With a balanced signal path and top-tier analog components, it delivers rich, detailed tone while maintaining exceptional clarity and control.

Designed with flexibility in mind, the BC5000 includes switchable BX1 and BX5 transformers, a fast FET limiter, and tools for fine-tuning your sound such as a sidechain low-cut filter, a one-button de-esser, and a high-frequency boost. From tightening low-end punch to refining vocal transients, it handles dynamics with subtlety and strength. With stepped controls for recallable settings and a low noise floor, it fits seamlessly into mixing and mastering workflows where precision and musical tone are essential.
