Burl Audio BAD4M ADC Card
The Burl Audio BAD4M ADC Card is designed specifically for mixing and mastering, using BURL's NextGen analog technology for superior fidelity and clarity, and offers 4-channel of Analog to Digital Conversion for the B80 and B16 MOTHERSHIP with stepped attenuators and switchable input transformers.
The Burl Audio BAD4M ADC Card is available with a few customer options. First is face plate orientation. If you have a B80, the face plates for the BAD4M should be vertical, and for the B16 horizontal. Please ensure you select the proper orientation at the drop down menu above for which Mothership you have.
The second custom option is in the OpAmp configuration.
- Version 1414: utilizing BOPA14’s on all channels.
- Version 1114: utilizing BOPA11 on channels 1/2, and BOPA14 on channels 3/4.
- Version 1111: utilizing BOPA11’s on all channels.
The differences between these OpAms are: "The BOPA11 is ideal for mastering, with maximum clarity, detail, and minimal distortion. The BOPA14, which was initially designed for the BDA8, has a slightly more pleasing tone and is preferred for mix down." All versions feature the switchable BX1 input transformer.
The Burl Audio BAD4M ADC Card is the result of over 25 years of R&D experience in pro audio digital and analog design. Following on the success of the B2 BOMBER ADC and the BAD8 for the MOTHERSHIP, the BAD4M utilizes BURL Audio’s NextGen Analog technology with the same BX1 transformer coupled circuit path as the BAD8 (no op-amps) and a transformerless analog front end using BOPA14. The BAD4M allows you to switch between the BAD8 style analog front end and the newly developed, BOPA14 based, transformerless analog front end. The new BOPA14 with BURL NextGen Analog is the result of hundreds of hours of listening tests. It boasts stunning clarity and definition and raises the bar of excellence in pro audio analog electronics fidelity. The BOPA14 is an all discrete, class-A op-amp with a minimal number of transistors. This new analog design will blow your mind with tighter bass and higher definition throughout the audio spectrum.
The BAD4M transformerless analog front end is perfect for situations where you want a pure capture of a mix or mastering chain where the signal is already warm and peak limited. The BOPA14 ensures a truly clear, faithful capture of the source material. On the digital side, the BAD4M employs a couple of new features; a switchable ADC filter and AVID delay matching. Switching the ADC filter allows you to change the tone from the classic BURL sound to a more aggressive tone with a more forward mid-range. The AVID delay matching allows you to perfectly match the input delay of an AVID IO which is crucial for hardware inserts.
