DSP BOARD 114 REV C

©1998 Mackie Designs Inc. All rights reserved

This portion of the DSP board repeats 24 times with only small variations.
All resistors, caps and ICs have different reference designators as shown in the 
tables on the following pages. Sadly, dear reader, they do not follow the usual 100's 
thing found on other boards.
Points marked with an asterix also change label as shown in the table on the next 
page, the other points do not change label.

As the 74AC32 is shared with two DSP channels,
the pin-outs for D and C are like this:
