ADAT Daughterboard and XDTDM

The ADAT daughter card, despite the fact that its original design dates back to 1999, is still fully supported in Pyra-
mix V6.1 in legacy HDTDM mode (64 I/O channels)
However, the use of this daughter card in XDTDM mode (128 I/O channels) is not guaranteed without the upgrade
described below. The much higher transmission frequencies, employed in order to convey double the number of
audio channels over the XDTDM bus, require an improved ground plane, which is achieved with an additional con-
ductive shield:
• To work properly in XDTDM mode, the ADAT daughter card has to be retrofitted with a shield, tightly
screwed to the card in order to ensure proper grounding. Should you have an ADAT card, not yet retrofit-
ted with a Shield, that you wish to use in XDTDM Mode, please contact your Merging Sales Partner.
Note: In XDTDM mode, the ADAT daughterboard will only support 8 output channels
through optical output A, duplicated through optical output B. ADAT inputs are no
longer available in the XDTDM mode.
