Warm Audio WA-2A Tube Opto Compressor

Opto compressor featuring the warm, forgiving, fluid qualities of the classic 2A
MFR# WA-2A

Product Description

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 Warm Audio WA-2A Tube Opto Compressor would be for nothing if Warm couldn’t make it affordable. Since the start of Warm Audio, they have striven to give unprecedented value by putting high end audio within the reach of more people than ever before.

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.

The WA-2A operates on four tubes: two 12AX7s, one 12BH7, and one 6AQ5 (or 6P1J). Warm 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.

My vocals immediately sounded better just by adding the WA2A to my signal chain.

By Channing E on March 31, 2021

Superb sound, especially for the price! I've only recorded rap vocals through it, but the first time I used it there was a BIG, instantly noticeable (and very desirable) difference from how my vocal recordings sounded before.

I've been using a Rode NT-2A (not my favorite mic, but the only one I've had lately, and it's decent) through a Warm Audio WA-12 preamp, through the WA-2A, into my recording interface. My vocal recordings sound "more pro" and require less mixing to achieve a good result, compared to when I was just using the Warm pre without the WA-2A.

I must have a slightly older model of the WA-2A, because it looks exactly the same and has all the same controls, but on mine the pre-emphasis and meter knobs are on the back of the unit. Which is funny, because that was my only complaint about this thing -- these knobs being on the back of the unit is inconvenient, and it seemed like there was room to put them on the front instead. Looks like Warm already fixed my only complaint!

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
