Burl B2 Bomber ADC

The Burl B2 Bomber ADC:

• 2-channel AD converter
• Clean and clear sound with the possibility of saturation
  
• Discrete and DC coupled signal path (fully Class-A)
  
• Proprietary high-resolution BX1 input transformer
  
• Detented knob for setting the digital headroom (post transformer)
  
• High-resolution metering with large LED display in 30 segments
  
• Simultaneous metering of RMS, Level & Peak
  
• Equipped with 2x AES/EBU, SPDIF Coaxial and Toslink outputs
  
• Frequency response at 48 kHz: 12 Hz - 22,000 Hz (+/- 0.1dB)
  
• Frequency response at 96 kHz: 15 Hz - 46,000 Hz (+/- 0.1dB)
• Frequency response at 192 kHz: 18 Hz - 94,000 Hz (+/- 0.1dB)

The crucial difference ...

The B2 Bomber from Burl Audio is a 2-channel AD converter, in which, in addition to the quality of the AD conversion, a lot of emphasis was placed on a high-class analog section. If you open the preamps or other outboard equipment in a professional studio, you will find high-quality components such as tubes, transformers or selected capacitors. However, if you take a look inside a converter, you'll find cheap 10-cent capacitors and ordinary 25-cent opamps, even if you spent a lot of money on the converter or interface. Most DAW hardware interfaces are designed for interconnectivity and pay little attention to the analog audio path or even the conversion, let alone the sound.

... lies in the analog part!

With the B2 Bomber, Burl Audio has solved this problem by developing an analog audio path that meets the same quality standards as high-end analog studio equipment. Using a revolutionary hybrid circuit with the proprietary BX1 input transformer and a discrete Class A signal path without capacitors, the B2 Bomber delivers dynamics and tonal balance unlike any other device on the market.

For Recording, Mix and Mastering

Using a B2 Bomber at a studio is like taking a towel off your speakers. And the B2 isn't just great for recording. Mixing and mastering in particular were the focus of the B2 layout and design. The large LED display in 30 segments reliably shows peak and RMS level, and always have an overview of how hot the signal is just driven. Especially in mastering this is absolutely crucial.

How do I work with the input transformer?

The digital headrom behind the input transformer can be adjusted with the detented knob on the front panel. If you want to drive the transformer hotter, you lower the "Input Level" and send more level from the front end into the B2 Bomber. Driving the BX 1 input transformer hotter creates saturation and compression effects that are reminiscent of tape machine saturation in their musicality. There is no need for false modesty here: A hot B2 Bomber ADC sounds fantastic! If, on the other hand, a clean transfer is desired, turn down the front end and increase the B2 's "Input Level".
