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 this classic ‘2A-style 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.
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. The WA-2A operates on four tubes: two 12AX7’s, one 12BH7, and one 6P1J. This product proudly uses Tung-Sol and Electro-Harmonix brand tubes in the signal path, which sound very ‘open’ and LARGE. All 4 tubes are socketed for easy swapping and replacement.
