D19m Technical Description
E54 D19m
Date printed:
30.06.20
Synchronization: When using, for example, a DA-88 unit, a word clock signal must be sent
over a separate line, because the DA-88 cannot sync to the LRCK signal.
For this purpose, the BNC Board 1.940.633 is available. It can be con-
nected to the TDIF Interface Card 1.940.632.
Note: The phase position of the word clock signal is very critical. No other word
clock signal must be used in this application.
