Output
Enable the
Output
option to apply sample rate
conversion on output. Select this option if
HD MADI is sending to external MADI sources
at any sample rate other than the Pro Tools Ses-
sion sample rate.
Clock Source
Select the desired Clock Source option to set the
clock source for Sample Rate Conversion (SRC)
on output.
SRC Word Clock In 1 Select this option to clock
to the SRC Word Clock In 1 port for SRC.
SRC Word Clock In 2
Select this option to clock
to the SRC Word Clock In 2 port for SRC.
SRC AES/EBU
Select this option to clock to the
SRC AES/EBU port for SRC.

Select this option to clock to the incom-
ing MADI signal (Optical or Coaxial) for SRC.
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:
• 44.1 kHz/48 kHz
• 88.2 kHz/96 kHz
• 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 devices
attached to HD MADI, select the appropriate
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.
