NOTE
High-speed connections cannot be made using the TAS-
CAM DM-24 digital mixing console. They may not be
supported by other equipment, and you should check
carefully in the documentation of all the components of
your system to ensure that this is a valid option.
Only the analog and AES/EBU connections and option
cards support 96k operation on the DS-M7.1.
Inverting the word clock
In some cases, the polarity of the word clock received
at the
WORD IN
connector may be inverted relative
to what the DS-M7.1 expects (since no industry stan-
dard has been universally adopted). In this case, you
may need to invert the polarity of the clock so that it
syncs accurately with the other devices in the setup.

No master clock.
Check the connections between the DS-M7.1 and the clock master, and check the set-
tings on the clock master to ensure that it is actually outputting a word sync signal.
1
Master clock out of range (44.1 kHz)
Check the settings of the clock master, and make sure that it is within ±6% of the
stated nominal frequency
2
Master clock out of range (48 kHz)
3
Master clock out of range (88.2 kHz)
4
Master clock out of range (96 kHz)
