BURL BAD4M for B80 4-ch Mastering grade ADC

The BAD4M, a mastering grade, 4-channel ADC daughter card for the B80 and B16 MOTHERSHIP with stepped attenuators and switchable input transformers. Specifically designed for mixing and mastering, the BAD4M uses the latest BURL NextGen analog technology for superior fidelity and clarity.

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.
