Burl Audio BDAM-1414 4-Channel DAC Card for B80 Mothership

Bring the depth, clarity and unmistakable analog character of Burl Audio conversion to the final stages of your mixing and mastering workflow. The Burl Audio BDAM-1414 BDA4M 4-channel DAC card for B80 Mothership combines mastering-grade digital-to-analog conversion with Burl's NextGen Analog technology, switchable BX5 output transformers and precision-stepped attenuators. Designed for the B80 and B16 Mothership platforms, the BDA4M features four channels of high-performance conversion built around the newly developed discrete Class-A BOPA14 op-amp, delivering enhanced definition, tighter bass and exceptional clarity across the frequency spectrum. Its switchable transformer architecture allows engineers to move between clean, detailed reproduction and the rich harmonic character of Burl's renowned BX5 transformers, while selectable DAC filtering provides additional tonal flexibility. With 115dB dynamic range, support for sample rates up to 192kHz and four XLR outputs, the BDA4M provides the precision and musicality demanded by professional mixing and mastering environments.

NextGen Class-A Circuitry and BX5 Transformers Shape Analog Character

The BDA4M incorporates Burl's newly developed BOPA14 discrete Class-A op-amp, engineered through extensive listening tests to deliver improved low-frequency definition, clarity and detail compared with previous analog designs. Its minimalist transistor architecture forms the foundation of Burl NextGen Analog, providing high-fidelity reproduction while preserving the musical character associated with the company's conversion technology. Each channel can engage a BX5 output transformer, the same transformer design featured in the acclaimed B32 VANCOUVER MIX BUS, to introduce additional weight, depth and harmonic richness to drums, bass, guitars, vocals and full mixes. Engineers can switch between transformer-coupled and cleaner output configurations, allowing the BDA4M to adapt to different material and production goals. When paired with compatible Burl analog-to-digital converters featuring BX1 input transformers, the system also supports analog processing loops that introduce transformer character without the tape hiss associated with traditional tape-based workflows.

Stepped Attenuation and Advanced DAC Control Support Precision Mastering

Designed for detailed mixing and mastering applications, the BDA4M provides B2 BOMBER-style stepped attenuation for repeatable output-level adjustments and precise monitoring control. A selectable DAC filter allows engineers to move between the classic Burl sonic character and a more aggressive response with a forward midrange, providing another way to tailor conversion to the source material. Avid delay matching helps align output timing with compatible Avid interfaces, making the card particularly useful for hardware insert workflows where accurate signal timing is essential. Four XLR outputs provide professional connectivity, while a frequency response extending from 10Hz to 22kHz at 48kHz sampling and up to 30kHz at higher sample rates supports detailed audio reproduction. With 115dB dynamic range, -96dB THD+N and a full-scale output level of +22dBu, the rugged, American-made BDA4M provides a versatile conversion solution for engineers seeking precision, tonal flexibility and distinctive analog character within their Burl Mothership system.
