Warm Audio's WA-2A set its target high: the most iconic tube compressor in history. How does Warm do it? Through economies of scale, mostly.
Analog Tone
Though digital technology and software have made great strides in recent years; we still believe that nothing compares to the level of articulation, depth, realism, and responsiveness of a well-built piece of analog gear. When you hear the bottom-end presence and top-end detail of quality analog gear, the difference is astounding. The cost of most boutique analog equipment is financially out of reach for many recording artists. Our mission is to change this, and introduce as many people as we can to recording and mixing with real, dedicated hardware.
'2A Style Optical Compressor
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. Since the start of Warm Audio we have striven 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.
Premium Components
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). We proudly use 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.
