BAD4M Op-amp Configuration
The BAD4M Daughter Card can be customized with four channels of the BOPA14,
four channels of the BOPA11, or two channels of each op-amp.
The BOPA11 is ideal for mastering, with maximum clarity, detail, and minimal dis-
tortion. The BOPA14, which was initially designed for the BDA8, has a slightly more
pleasing tone and is preferred for mix down.
