BURL Audio B2 Bomber 2-Channel AD Converter

Two-channel 192 kHz analog/digital converter equipped with all Class A, discrete transistors

Product Description

The Burl Audio B2 Bomber ADC is a two-channel analog to digital converter designed to recreate the warmth and feel of analog tape recordings. Equipped with an all Class A, discrete transistors, the B2 Bomber ADC delivers the ultimate analog tone when recording, mixing or mastering.


Your sound is only as strong as the weakest link in your signal chain. Vintage mics, tube preamps, and analog outboard gear are great for adding color and character to performances, but running your signal through a cheap ADC will leave it sounding weak and sterile. If you want true analog tone, you need an ADC designed to compliment the rest of your signal chain.

The B2 Bomber ADC utilizes a revolutionary hybrid circuit to achieve the tone and depth of classic analog recordings. Equipped with the proprietary BX1 transformer, and a discrete Class A, zero feedback, zero capacitor signal path, the B2 Bomber ADC delivers unparalleled tonal balance.


The Burl B2 Bomber ADC offers flexible routing for connecting to an array of digital audio devices. In addition to standard XLR audio and BNC word clock inputs, the Bomber features connections for SPDIF, Toslink and two AES outputs.

The Bomber ADC features a clean, sleek, intuitive interface that looks great in any studio. Quickly dial in the perfect amount of saturation with the audiophile-quality six-position attenuator. Keep an eye on your signal using the high-definition meter with simultaneous RMS and peak indication. Push the Bomber into the red for pure analog distortion, or back off for a more transparent sound. No matter how you use it, the B2 Bomber ADC will be the most significant piece of gear in your studio.

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

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.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
