An Inspired Re-creation of the Legendary ’251

The Warm Audio WA-251 is a faithful replica of the classic ’251-style large-diaphragm condenser microphone. The original, introduced in 1960, is reverentially considered to be one of the most gorgeous-sounding mics ever made. With rare working-condition vintage ’251s going for big money, the WA-251 is a no-brainer if you’re after that uniquely smooth, present, and open sound you’ve heard on countless hits. Simply put, this microphone delivers sumptuous results on any instrument. Stock your mic locker with a meticulous rendition of a classic: the Warm Audio WA-251.

A sound heard on countless iconic recordings

Their acclaimed vintage-inspired compressors, preamps, and mics have famously upset the pro audio price/performance ratio, so when Warm Audio turned its attention to the godfather of large-diaphragm tube condenser microphones, you know it had to be good. And is it ever! With its discrete, transformer-balanced vacuum tube circuitry and custom reproduction capsule, the Warm Audio WA-251 nails the huge, creamy sound of the beloved and revered ’251 — a sound heard on countless iconic recordings.

No source the WA-251 can’t finesse

Flash back to any top recording studio in the 1960s, and you’d see the venerable ’251 everywhere. Now it occupies a lofty perch in the pantheon of the greatest microphones ever made. It’s this classic circuit design — dating back more than a half century — that Warm Audio closely followed for the WA-251. This faithful replica uses a custom all-brass true CK-12-style capsule. Three polar patterns and robust 132dB SPL handling translate to incredible versatility; there’s literally no source the WA-251 can’t finesse with its inimitable, seductive sonics. Engineers at Sweetwater who have worked with the iconic original are beyond impressed. And you will be too.

Explore the sonic possibilities

The WA-251’s three polar patterns — cardioid, omnidirectional, and figure-8 — give you immense flexibility when it comes to exploring the sonic possibilities offered by different recording techniques. With two of these superb microphones, you can implement stereo techniques such as spaced pair (A/B), XY (including Blumlein), ORTF array, and mid-side (M-S). For full orchestra, add a third WA-251 for the minimalist — and highly effective — Mercury Living Presence technique: three spaced omnis across the orchestral soundstage, centered above the conductor’s podium. Set all three channels for unity gain, trim for the loudest musical peaks, and leave those faders alone. Let the conductor balance the orchestra (as nature intended).

A ’251 for the rest of us

What can you achieve with the WA-251? Every studio needs at least one pair of high-quality large-diaphragm condenser mics, and the Warm Audio WA-251 is designed after a legendary one. You can use the WA-251 on anything — with world-class results. It’s simply stunning on vocals, acoustic guitars, double bass, electric guitar and bass cabs, piano, drums and percussion, strings, brass, woodwinds, and any other source you’d care to throw at it. In fact, you could mic an entire symphony orchestra with nothing but three judiciously placed WA-251s set to omni. Considering its amazing value, it would be wise to get two for recording tracks in stereo. You haven’t lived until you’ve heard a grand piano spring to life when miked with a pair of ’251s. For drum room mics, use two WA-251s and nuke the stereo signal with a fast compressor. Positively explosive!

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Reviews

Well worth the price!
I bought this mic a while back and have been very happy with it so far. It has a nice, full mid range with a great, open top end, without sounding overly hyped or harsh like a lot of budget friendly mics. Overall very natural sounding and seems to fit a lot of vocalists voices nicely.

It's a Beauty!
So I've owned a Lawson L251 for 20 years. It's an amazing 251 replica (depending on the era). Found this on Youtube and at the suggestion of Josh Trumm, my salesperson here, I grabbed it. You should too! After only a few weeks, I'm in love. Not only is it a beautiful looking mic, on vocals and acoustic guitar it's amazing. Clean crisp top end, creamy mid and a really round low end. Only$??? It's a no brainer. Click and grab!! You won't regret it.

Clarity and Warmth
Granted I'm upgrading from a less expensive condenser mic, I am constantly in professional studios recording. With a simple isolation shield this mic has value well beyond it's price and compares to mics in the thousands that I've used. Definitely grab one!

This is the one
this is the mic to get for the price..
The sound is just what I was looking for.
Now the shockmount I don't really like the clamps its not secure enough for me I can tap it with my finger slightly and it slips. I like the one that aventone makes with the screws to tighten it down tight so if an artist bumps it it will stay in place.

Like butter for my voice
This mic is like butter for my voice. I love the smooth, rich tube sound it gives. In a 5-way mic comparison it was always the one I ended up choosing for my vocals. It sounds pretty good on acoustic guitar, too. I hope to try it soon on some more instruments to see how it compares with other mics in my locker. It also looks mighty cool!
