Locked to AES3 Input
If this setting is used, the codec will use the sync information received by the AES3 input to set
the output sample rate in the codec (Note: this is the same as the AES Rx Clock setting in
Tieline G3 codecs). The codec will initially try to use the signal on AES inputs 1 and 2 as the
clock to which the AES outputs are synchronized. If unavailable, it will then attempt to use
inputs 3 and 4 or inputs 5 and 6 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 inputs 3 and 4 and inputs 5 and 6 must also be synchronized to the same clock.
Wordclock Sync In
This setting configures the codec for a word clock source via the SYNC INPUT on the codec
rear panel (this is the same as the External Word Clock setting in Tieline G3 codecs). Often
this will be a studio reference signal (D.A.R.S., or Digital Audio Reference Signal). In television
broadcasting facilities, the audio reference signal should be locked to the video reference if there
is one available. The sample rate being received is recognized by the codec and automatically
adjusted within it. Sample rates from 32 kHz to 96 kHz are accepted, including the most
popular rates of 32 kHz, 44.1 kHz and 48 kHz.
Fixed Sample Clock
Select from a range of fixed output sample rates.
