The A-to-D Conversion Quality You Need!

The Burl Audio Audio B2 Bomber ADC analog-to-digital converter may just be the most important piece of gear in your studio. No matter how good your microphones, compressors, or other pieces of your input signal path may be, if your converters don't hold up, your tracks won't sound their best. An excellent clock isn't enough. That's why Burl built their B2 Bomber ADC with a top-quality analog signal path to match its digital converter. At Sweetwater, we've heard a lot of A-to-D converters - find out for yourself why we consider the Burl Audio B2 Bomber ADC one of the best!

Burl Audio B2 Bomber ADC Analog-to-digital Converter at a Glance:
  • An A-to-D that's more than just a converter
  • The finishing touch to your analog signal path
  • The simplest front-panel interface on the market
An A-to-D that's more than just a converter

The Burl Audio B2 Bomber ADC isn't your typical run-of-the-mill analog-to-digital converter. The reason for this is simple. Most A-to-D converters use top-shelf clocking circuits, isolated power rails, and other key conversion components. By contrast, their analog signal paths are merely adequate. That's where the Burl Audio B2 Bomber ADC goes leaps and bounds beyond typical A-to-D converters. Not only does it provide you with unrivaled A-to-D conversion, but its analog signal path is on par with the best all-analog audio gear out there - no 10-cent capacitors or 25-cent op-amps here! Better-sounding audio before conversion means better sounding tracks. Don't settle for less.

The finishing touch to your analog signal path

For most engineers, it's hard to think of your A-to-D converter as the last step in your analog signal path. Fortunately, that's exactly the approach Burl Audio took when they designed their B2 Bomber ADC. That's why they gave the B2 Bomber ADC their revolutionary BURL AUDIO BX1 hybrid circuit/proprietary transformer combination. Using a discrete Class A, zero-feedback, zero-capacitor signal path, the B2 Bomber ADC responds to incoming audio like tape. The hotter you hit it, the more natural saturation you get. Coupled with Burl's top-of-the-line clock, the B2 Bomber ADC gives you unrivaled conversion with unheard-of headroom.

The simplest front-panel interface on the market

From the layout of the B2 Bomber ADC's front panel, it's easy to see that Burl Audio doesn't believe in senseless overengineering. Whereas many A-to-D converters sport fancy digital displays with controls that make them about as pleasant to setup as a digital wrist watch, the B2 Bomber ADC features a streamlined set of simple dials. Changing the B2 Bomber ADC's settings from an internal clock set to 48kHz with -12dB of input attenuation to an external clock at 192kHz with -20dB attenuation takes less time than it just took you to read this sentence. How cool is that!? What's more, you get a bright, easy-to-read 30-segment LED meter, so you know exactly how hot you're running your input signal.

Burl Audio B2 Bomber ADC Analog-to-digital Converter Features:
  • Professional 2-channel analog-to-digital conversion with a unique high-quality analog input signal path provides the missing link between your analog input path and your DAW
  • Proprietary, high-definition, BURL Audio BX1 transformer input reacts to incoming signal like tape
  • Discrete Class A transistor-based signal path with zero feedback and no capacitors ensure absolute audio fidelity
  • Simple front-panel knob-based controls make dialing in settings easy
  • 6-position audiophile-quality attenuator lets you select form common headroom settings
  • Impressive 120dB of dynamic range gives you plenty of headroom
  • 30-segment RMS-based LED meter provides bright, easy-to-read input-level feedback for both channels
  • Select from 6 sample rate settings, including 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz
  • BNC word clock input with two outputs of extremely low jitter clock
  • 2x AES outputs and 1 x (2-channel) SPDIF output with dual-wire AES support
  • Proudly made in the USA
The Burl Audio B2 Bomber ADC analog-to-digital takes quality A-to-D conversion to the next level!

The Green Tape Machine

This is quite possibly the most significant piece of gear I own. Tracking through it opens everything up and gives it a remarkable 3D depth and clarity. Mixing through it makes decision making so much easier as it adds a girth and character and subtle color to what would normally be a sterile logic mixdown. You would be AMAZED by how much less you'll feel the need to eq, compress, etc. or at the very least how much easier you'll be able to hear the benefit/lack thereof of all plugins you're using while running your two stereo mix through this thing. Next, slaving my Apollo to the Bomber's internal clock makes a significant and discernible difference in the way my recorded tracks and 2 bus summed mixes sound. Jitter is nonexistent and I've never once heard a click or pop while printing a song to a new stereo track. Lastly, while I typically enjoy sending a mix with lots of headroom through this thing and then bringing the volume up later with mult-band compression and limiting, I find that this unit clips very musically and that being said, don't be afraid to clip this thing if it yeilds a pleasing end result. Oh, and absolutely play around with the input attenuation. Running it cold will keep the transients more open and the effect is open and subtle while pushing it hard (and you can hit this thing very hard) you'll get the added effect of more harmonic saturation and rounded off transients which can sometimes be a very good thing. Don't think twice. Compared to the stock A/D converters/clock in my Apollo Twin, it's like comparing a Toyota Corolla to a Bugatti. lol

Amazing...

This piece has completely changed the way i record & mix in my home project studio... outboard analog gear that i had come to believe just wasn't worth having anymore because software seemed to work better, now functions and sounds the way you remember & expect it to - way better than software when running back in using the B2's A/D converter. Tracks recorded thru the A/D are much better quality as well, i love this piece.

STUNNING WOW

I BOUGHT THE ORION AND RETURNED IT FOR A HILO BECAUSE THE HILO BLOW THE ORION OUT THE WATER SO I WAS VERY HAPPY WITH MY SETUP BUT I WAS WONDERING IF THERE WAS A BETTER SOUNDING CONVERTER IN THIS PRICE POINT?? AND ALSO I WAS LOOKING FOR A CONVERTER I CAN MASTER WITH SINCE I WAS TRACKING WITH THE HILO AS MY MAIN AD/DA MOST OF MY ENGINEERING FRIENDS SAID GET THE BURL B2 BOOMER SO I CALLED UP MY REP @ SWEETWATER AND HE SHIP ME OUT ONE WHEN I A/B IT WITH THE HILO O.M.G I WAS FLOORED IT IS THE CLOSEST THING TO ANALOG SO FAR MAN I 'M IN LOVE WITH IT NOW I HAVE A MASTER CONVERTER I CAN DEPEND ON

Just Simply Amazing

So I have had some time with this product and have had chances to A/B against other converters. In my quest of going through every converter I finally landed on the right signal. With most converters I would track but was not simply 100% satisfied. This converter leaves nothing left to be desired when tracking. If you are tracking bass and guitars you will know exactly what I mean. I highly recommend you shelf out the extra cash this is completely worth it.

ADC Perfection

OM freakin G !!!!!!!!!!!!!!!!!!!!!! Been waiting 20 years to say this.... digital conversion has TRULY finally arrivied! Forget Apogee, forget Lavry, forget Prisim, Ive used them all... Somebody FINALLY nailed it. Congratulations (and THANK YOU!) Burl Audio for giving SOUND back to us , that was no small feat.

Sweetwater Advice

Thomas Leahy

I frequently use the Burl B2 Bomber ADC on vocals, bass, guitars, and anything else that needs massive amounts of depth and clarity. I love driving signal through it, and the variable input level lets me hit the sweet spot on my preamp, without overloading the converter. Between the transformer and the converter, it's the closest thing to tape out there.
