)
A949.0426
This card provides two eight-channel TDIF I/O interfaces with 96 kHz,
88.2 kHz, 48 kHz, or 44.1 kHz operation with wordclock sync outputs on
BNC connectors. Inputs and outputs are provided on standard 25-pin D-type
connectors (female).
In 96/88.2 kHz operation, the number of channels is limited to eight, i.e. four
per I/O.

In 96 kHz mode the card handles a total of 8 channels (4 per interface). In
order to avoid different numbers of channels when switching from 96 kHz
to 48 kHz and vice versa, it is possible to restrict the card to 8 channels even
in 48 kHz mode. In such a case only the first interface (
TDIF IN/OUT CH
1-8
) is active, as shown in the table below.
