• This adjustment can also be used in cases where a low‐level signal source
must be used. Again you should use the rated clip point of the source device
to determine the closest setting. Simply add gain to bring this rated clip
point up to +22 dBu.
AES sources. In the case of AES sources, this adjustment can be used to adjust system
headroom. This should be done with care and deliberation.
While we don’t recommend setting levels “by eye,” if you choose to do so, you can use the Send
meters as your guide.
AUDIO – Screen 2
INPUT SOURCE: (Analog; AES/EBU; Livewire)
This selection determines which inputs are active. Your options are Analog, AES and Livewire.
Note that analog, AES/EBU, and Livewire outputs are always (simultaneously) active.
AES SAMPLE:
This determines the sample rate of the AES/EBU Output signal as follows:
Codec
This option uses the sample rate selected in the Codec menu. This is the
“transmission” sample rate and is derived from the ISDN (or V.35) clock. Use
this option only the AES/EBU equipment being fed is tied to this network clock
(for example, another codec).
Sync:
This option sample rate converts the codec receive audio to the rate of the
AES/EBU signal present at the SYNC‐IN jack for output at the AES/EBU Out jack
on the rear of the Zephyr Xstream. This can be any AES/EBU signal; any audio
present will be ignored.
AES Input:
This is the usual setting if a house sync is not used; this option sample‐rate‐
converts the codec receive audio (set in the AUDIO menu) to the rate of the
AES/EBU signal present at the AES/EBU IN jack for output at the AES/EBU Out
jack on the rear of the Zephyr Xstream. This option allows easy synchronisation
to your clock reference, when the Xstream's AES/EBU In is fed from a device
already tied to your house clock reference.
