Vintage Style Optical 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.

Releasing the WA-2A would be for nothing if we couldn't make it affordable. Since the start of Warm Audio we have strived to give an unprecedented value to our customers, by putting high end audio within the reach of more people than ever before. This philosophy drives everything we do, and every product we offer.

Welcome to the future of vintage!
