Audio Input Configuration Dialog Box and Selection Process
1
NAV Audio
— Click to enable and disable
NAV
Audio
. NAV audio is the default
encrypted audio signal.
2
AES67
— Click to enable and disable
AES67
. AES67 is a standards-based audio over
IP signal.
3
PTP
(Precision Time Protocol)
Domain ID
— Click in the
PTP
Domain
ID
field and
edit it as desired or click or to increment or decrement the
PTP
Domain
ID
. If
you change the value, the unit re-synchronize
s its
sits
internal audio time clock to the
domain of the newly entered value.
NOTE:
PTP Domain is an integer value used with AES67 to logically group PTP
clocks on a network. This synchronizes their clocks to eliminate latency between
the audio signals. Endpoints can only synchronize to other devices in the same
domain and devices outside the domain are ignored.
•
If you enter a value above the valid range, such as
128
, the software
automatically drops the value to 127.
•
If you enter a valid, but incorrect, domain, the decoder syncs to the new
domain clocks and there is a potential for interrupted audio.
