Description

The Burl Audio B2 Bomber is a 2-channel, 24-bit/192kHz analog-to-digital converter with transformer input, incredibly low-jitter clocking, precision metering, and stepped attenuators

If you thought the military’s supersonic B1 bomber was formidable, you haven’t heard anything until you put a Burl B2 Bomber ADC in your racks. In these days of low-cost, high track-count interfaces, where the concentration is on connectivity and bang-for-the-buck, compromises have to made. It follows, that for tracks that can compete with unlimited budgets, you need at least two channels of no-compromise ADC—you need a Burl B2 Bomber ADC. Using a B2 Bomber ADC in your studio is like taking a blanket off your speakers. Not just for tracking, the B2Bomber ADC is designed for mixdown and mastering. If you’ve used up all your wife points spending a fortune on great mics, mic preamps, and DAW, and don’t have a Burl B2 Bomber ADC, you’re missing the key component; an ADC with an audio path worthy of your recordings.

Burl Audio B2 Bomber ADC in one take:

• Two-channel ADC; 24 bit/44.1kHz-192kHz
• Proprietary, high definition, Burl Audio BX1 transformer input
• All Class-A, discrete transistors signal path with zero feedback and no capacitors
• Audiophile-quality, 6-position attenuator with standard headroom settings
• High-definition metering with simultaneous RMS and peak indication
• Dante, 2x AES, SPDIF, and Toslink output
• BNC word clock input with two outputs of extremely low-jitter clock
• Rugged design, made in the USA

INSIDE THE BOX—Burl Audio B2 Bomber ADC

One of the secrets of creating high-quality converters is understanding how to design analog properly, which is where Burl products shine. If you open up your best mic preamp and look inside, you’ll see high-quality components, such as tubes, large custom transformers, and audiophile-grade capacitors. However, inside most ADC’s, you’ll often find cheap capacitors and run-of-the-mill op-amps, even when you’ve spent a lot of money on your interface. Most DAW hardware interfaces are designed for inter-connectivity with little attention paid to the analog audio path, not to mention tone.

While the B2 Bomber ADC has great specifications, specs alone don’t predict performance. That’s why the B2 ADC is ear-tested to give you the ultimate in recording tone. For years, audio professionals have missed the feel and saturation of analog tape in digital recordings, trying to compensate with high-end tube mics, great preamps and outboard, but there’s still the blurriness, graininess, and lack of depth that comes with digital recordings.

Burl Audio has solved this problem by designing an analog audio path with a revolutionary hybrid circuit, BX1 custom transformer, and a discrete class-A, zero feedback, zero capacitor signal path. With the B2 ADC’s analog circuitry, Burl has achieved dynamic and tonal balance reminiscent of analog tape, but without the inconsistencies and loss of transients and high frequencies.

Much like an analog console 2-bus to tape, the B2 gives you the ability to hit the front end hotter for more saturation via the front-panel attenuator. In fact, the B2 Bomber only sounds better when you run it hot. Couple that with an extremely low jitter clock source, and you have the B2 Bomber ADC, the most significant piece of gear in your studio.

Dante AoIP network audio option

Dante AoIP (Audio over IP) is an extremely fast, low-latency device that lets you stream 64 channels of 24-bit/48kHz audio on a single network port with a default latency of 1ms. With Dante, you can run up to 512 24-bit/48kHz audio channels on a single Gigabit network port. Plus, you can add as many audio channels to a network as you want, simply by adding more Dante-enabled Burl or other interfaces. The ultimate in scalability, Dante features automatic device discovery. To make system control more intuitive, Dante assigns easily recognized device names. Remarkably cost-effective, Dante can use existing network infrastructure to send and receive audio in a multi-room facility.

Dante Virtual Soundcard

The Dante virtual soundcard is a software application that turns your PC or Mac into a Dante-enabled device, allowing audio to be transmitted and received using the standard Ethernet port. With no additional hardware necessary, you can run multiple B2 Bombers or a B80 Mothership from a laptop or other computer via a single Ethernet jack. Not only that, but any Dante-enabled digital gear, including mixing consoles, can directly interface with the B2 Bombers and B80 Mothership.

Dante AoIP features:

• View and change the current audio sample rate
• Customize the receive latency (latency a receiving device should use before play out)
• View and set your Ethernet network interface, and view network interface details
• Start and stop the Dante Virtual Soundcard
• Select the number of audio channels available in the Dante Virtual Soundcard (CoreAudio and ASIO only)
• On Windows, you can also select ASIO or WDM mode, view and set ASIO- specific parameters

OUTSIDE THE BOX—Burl Audio B2 Bomber ADC

Front-panel controls on the B2 ADC include a post-transformer Input Level Attenuator, that allows selection between analog +4dBu = -12, -14, -16, -18, -20, -22dBfs digital headroom; Dual Wire on/off for AES sample rate selection; high-resolution, 30-segment meter that shows RMS level and Peak simultaneously; Red “Lock” clock indicator; Peak Reset; Clock Source Select (Internal Clock, External clock (Word Clock), or Dante); and Sample-Rate Select for internal clock (44.1, 48, 88.2, 96, 176.4, 192kHz).

Rear-panel I/O include a Dante Ethernet output, two AES outputs (single and dual wire), TOSLINK digital output, S/PDIF digital output, one word clock input, two word clock outputs, analog output trim for fine-tuning levels, and balanced XLR inputs.

Once you hear what the Burl B2 Bomber ADC does for your tracks, it will become obvious that you owe it to your clients to own one. For more information, call or chat online with your Westlake Pro Sales Consultant today.
