The BAD4M and BDA4M Daughter Cards:

The BAD4M and BDA4M, mastering grade, 4-channel ADC and DAC Daughter Cards for the B80 and B16 MOTHERSHIP with switchable transformers and stepped attenuators are specifically designed for mixing and mastering. The BAD4M and BDA4M use the latest BURL NextGen Analog Technology for superior clarity and fidelity. The BAD4M and BDA4M are 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 Daughter Card 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 the BOPA14 op-amp. The BAD4M allows you to switch between the BAD8 style analog front end and the newly developed transformerless analog front end with the press of a button. The transformerless mode 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. In this mode, the BOPA14 delivers a truly clear and faithful capture of the source material.
The BDA4M follows on the success of the B2 BOMBER DAC and the BDA8 Daughter Card for the MOTHERSHIP and utilizes the newly developed BOPA11 and/or optional BOPA14 op-amps. The BOPA11 is followed by the renowned BX5 output transformer. The BX5 output transformer is the same large, BURLY beast used in BURL Audio’s popular B32 VANCOUVER MIX BUS. Anyone who has tried B32 for the first time and engages the BX5 usually says “WHOA! That’s amazing!”. Forget about technical jargon, the BX5 transformer simply makes things sound bigger, phatter, deeper…better.
