Burl Audio B2 Bomber ADC 2-Channel AD Converter

Capture the warmth, depth and musical character of your analog recordings without compromising the precision of digital production. The Burl Audio B2 Bomber ADC 2-channel analog-to-digital converter combines premium analog circuitry with high-resolution digital conversion to bring the rich, dimensional sound of classic analog recording into modern studio workflows. Designed for tracking, mixing and mastering, the B2 Bomber features proprietary BX1 input transformers and an all-discrete Class-A signal path designed without feedback or capacitors in the audio path. This distinctive architecture preserves the tonal balance and dynamic character of microphones, preamps and outboard processors while introducing the harmonic richness associated with Burl's transformer-based designs. Supporting 24-bit conversion at sample rates from 44.1kHz to 192kHz, the converter delivers 120dB A-weighted dynamic range, precision input attenuation and high-resolution metering for professional recording applications. With AES, S/PDIF and Toslink digital outputs, the B2 Bomber provides a powerful connection between high-quality analog equipment and digital recording systems.

BX1 Transformers and Discrete Class-A Circuitry Preserve Analog Character

The B2 Bomber uses Burl's proprietary BX1 input transformers and a discrete Class-A analog circuit to capture the warmth, depth and natural dynamics of incoming audio signals. Its zero-feedback, capacitor-free signal path is designed to complement high-quality microphone preamps and analog processors, preserving the character of the source while adding the musical response associated with transformer-coupled conversion. Unlike conventional converter designs that prioritize connectivity over analog signal quality, the B2 Bomber emphasizes the components and circuitry responsible for shaping the sound before it enters the digital domain. This approach makes it equally useful for capturing individual instruments and vocals or transferring complete stereo mixes into a DAW. A six-position audiophile-grade input attenuator provides selectable headroom settings, allowing engineers to drive the analog input stage harder for additional character or maintain a more conservative signal level when greater transparency is desired.

Precision Metering and Low-Jitter Clocking Support Critical Recording

Designed with professional mixing and mastering in mind, the B2 Bomber features 30-segment high-definition metering with simultaneous peak and RMS indication, giving engineers detailed visual feedback for managing recording levels and dynamic range. Its low-jitter internal clock supports accurate digital conversion, while a BNC word clock input and two clock outputs provide synchronization options for larger studio systems. Dual AES outputs, S/PDIF and Toslink connectivity allow integration with compatible digital recording equipment, making the converter adaptable to a variety of professional workflows. Frequency response spans 12Hz–22kHz at 48kHz sampling, 15Hz–46kHz at 96kHz and 18Hz–94kHz at 192kHz, with a specified tolerance of ±0.1dB. Delivering 120dB A-weighted dynamic range and THD+N as low as -100dB under specified operating conditions, the rugged, American-made Burl Audio B2 Bomber ADC combines high-resolution conversion, flexible signal management and distinctive analog character for engineers who want greater control over the sound of their digital recordings.
