Warm Audio WA-2A Tube Opto Compressor

True to its inspiration; the WA-2A boasts an all tube, completely discrete signal path with through-hole component topology.  It also features custom, large-core Cinemag input and output transformers, four premium vacuum tubes, and the legendary Kenetek opto-cell, considered by many to be the world's finest.

No plug-in or other compressor type quite compares to the warm, forgiving, fluid qualities of this classic optical tube compressor.  For decades, the renowned '2A type circuit has become the go-to device for seamlessly handling vocals, bass, and a wide variety of other instruments and program material in an effortlessly smooth way.
