1-channel Tube Optical Compressor with All-discrete Signal Path, Custom Optical Photocell, and Cinemag Transformers.
No plug-in or other compressor type quite compares to the warm, forgiving, fluid qualities of the classic '2A optical compressor. For decades, the renowned ‘2A style 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. The WA-2A is a high-voltage, Class-A opto-compressor, utilizing large-core CineMag USA Transformers, four premium vacuum tubes, and the legendary Kenetek opto-cell - considered by many to be the world’s finest.
A Four Tube Operation The WA-2A operates on four tubes: two 12AX7’s, one 12BH7, and one 6aq5 (or 6P1J).
