Word Clock Base Frequency (44.1/48)
Enable this option if you are synchronizing to
Word Clock at either 44.1 kHz or 48 kHz, but
you are sending at a sample rate of 88.2 kHz or
higher.
Target Output Rate
Select the desired output sample rate frequency
range for the MADI signal target output:
• 44.1kHz/48kHz
• 88.2kHz/96kHz
• 176.4 kHz/192 kHz
If the Word Clock Base Frequency option is en-
abled, the Target Output Rate setting multiplies
the Word Base Frequency (either 44.1 or 48 kHz)
to match the output sample rate range.
Ext. Clock Output
If you want to send clock output to other de-
vices attached to HD MADI, select the appropri-
ate output from the Ext. Clock Output pop-up
menu.
The available options for Ext. Clock Output
change depending on the session sample rate.
See the table below for a list of default external
clock settings and available options.
