BURL AUDIO BDA4M-B16-1414 4-Channel DAC Card for B16 Mothership

Give your mixes the depth, clarity and analog character they deserve before they reach the final master. The Burl Audio BDA4M-B16-1414 4-channel DAC card for B16 Mothership brings mastering-grade digital-to-analog conversion to professional mixing and mastering workflows, combining Burl's NextGen Analog technology with switchable BX5 output transformers and precision-stepped attenuators. Designed for the B16 and B80 Mothership systems, the BDA4M features four channels of high-performance conversion built around the discrete Class-A BOPA14 op-amp, delivering enhanced definition, tighter bass and exceptional clarity across the frequency spectrum. Switchable transformer coupling allows engineers to introduce the rich, powerful character of Burl's renowned BX5 transformers or maintain a cleaner signal path, while selectable DAC filters provide additional tonal flexibility. With 115dB dynamic range, support for sample rates up to 192kHz and dedicated XLR connectivity, the BDA4M delivers professional conversion with the flexibility to shape sound at the final stages of production.

NextGen Analog and BX5 Transformers Deliver Powerful Sonic Character

The BDA4M incorporates Burl's newly developed BOPA14 discrete Class-A op-amp, engineered through extensive listening tests to provide improved low-frequency definition, clarity and detail compared with previous analog designs. Its minimalist transistor architecture forms the foundation of Burl NextGen Analog, delivering high-fidelity reproduction while retaining 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 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 noise and maintenance associated with traditional tape-based workflows.

Stepped Attenuation and Advanced DAC Control Support Precision Mixing

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-B16-1414 provides a versatile conversion solution for engineers seeking precision, tonal flexibility and distinctive analog character within their Burl Mothership system.
