Input Equalization Settings (DV-33512 Models Only)
Recent versions of the DM-33512 Digital Matrix boards used in DV-
33512 routers have additional input equalization for improved HD per-
formance; these boards are identified with “Pre-emphasis Added”
stickers on the J421 headers used to connect the two halves of the board.
If these stickers are present, and you are operating with Broadlinx 2.4
software or newer, DIP switches S401-7 and S401-8 (on both boards)
should be set to “On;” if the stickers are not present, these switches
should be set to “Off.” The remaining six switches on S401 are always
set to “Off.” See Figure 72.
