42 Gateway and Gateway 4 Manual v1.2
With this setting the codec uses AES3 input sync information to set the codec output sample rate
(Note: this is the same as the AES Rx Clock setting in Tieline G3 codecs). The codec initially tries
to use the signal on AES inputs 1 and 2 as the clock to which the AES outputs are synchronized. If
unavailable, it then attempt to use inputs 3 and 4, or inputs 5 and 6 and so on in that order. If you
select this option, all AES inputs must always be synchronized to the same clock source, e.g. if
AES3 inputs 1 and 2 use 48kHz sampling then all other inputs must also be synchronized to the
same clock. Supported sample rates include 32 kHz, 44.1 kHz, 48 kHz and 96 kHz. Note: The
reference clock must be within +/- 50ppm of the listed sample rates.
Lock to AES11 Input
AES11 is a standard AES3 signal with an accurate clock reference (DARS, or Digital Audio
Reference Signal), usually without the audio data. To use this input attach a female BNC connector
to the SYNC I/O 1 connector on the codec rear panel. Supported sample rates include 32 kHz, 44.1
kHz, 48 kHz and 96 kHz. Note: The reference clock must be within +/- 50ppm of the listed sample
rates.
Lock to AES67 PTP
AES67/ST2110-30 derives the sampling clock from a primary leader clock over the network. This
clock can be selected as the AES3 Output Clock Source. The AES3 Output Clock Source is
forced to Lock to AES67 PTP if either the Digital Input Type or Digital Output Type is set to
AES67. If a WheatNet-IP card is installed, and the Digital Input Type or Digital Output Type is
set to WNIP, then the AES3 Output Clock Source is forced to Lock to WNIP Clock.
Fixed Sample Clock
Select from a range of fixed output sample rates including:
1. 32 kHz
2. 44.1 kHz
3. 48 kHz
4. 88.2 kHz
5. 96 kHz
Note: The reference clock must be within +/- 50ppm of the listed sample rates.
