SYSTEM MENU
Sample Rate Menu
The
Sample Rate
menu lets you choose the internal sample rate at which Omnia.7 will run, either 44.1kHz or
48kHz. The default rate is 44.1kHz. Be sure to select
Apply Config
to put the changes into effect, keeping in mind
that doing so will cause an interruption to program audio as Omnia.7 re-starts.
The main AES XLR inputs can accept audio with a reference of either 44.1kHz (for HD Radio) or 48kHz (for
DAB). To set the sample rate, navigate to the
System > System Configuration > Sample Rate
menu and set the unit’s
sample rate to match that of the incoming signal and the
Sync Reference
control to “Main Input”.
If the incoming AES audio has a different sample rate between 32kHz and 96kHz, it can be up- or down-sampled
to either 44.1 or 48kHz by setting the
Sync Reference
control to “Reference Input.” The unit’s sample rate must be
selected in the
Sample Rate
menu.
Finally, a dedicated external reference input is provided on the rear panel via a BNC connector should it be
necessary to sync to a clock that is not present on the incoming AES audio (such as an HD exporter at the transmit-
ter site). Set the
Sync Reference
to “Reference Input”. The unit’s sample rate must be selected in the
Sample Rate
menu. A BNC-to-XLR cable or adapter (Pin 2 hot, Pin 3 shield) may be used for short runs without concern. For
longer runs, a transformer should be used as needed.
Processing Paths Menu
The
MPX Power Control
is only applicable to the FM version of Omnia.7. It can be disregarded in the AM version.
Streaming Encoders
Allows you to set the maximum number of each of the available streaming encoders.
