Important information regarding BAD4M latency: The BAD4M uses jumpers on “JP1” (as shown on cover) to adjust 2 variables: ADC filter selection, high pass filter, and AVID HDIO delay matching. Jumper Settings for “JP1” Jumper A - ADC Filter Setting: In default mode with no jumpers set, the BAD4M uses the short delay filter with the classic “Burl Sound”. (Image 1) A jumper on “A” will switch to the long delay filter, with longer latency and a more forward mid-range.

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 BOPA14, which was initially designed for the BDA8, has a slightly more pleasing tone and is preferred for mix down. Image 13: BAD4M-1414, utilizing BOPA14’s on all channels.
