Fm Options - Omnia ONE FM Installation And Operation Manual

Right Trim
Allows a +/-3dB adjustment of the right digital audio channel gain to correct minor left/right
balance problems in equipment following the OmniaONE. The left channel output gain is not
affected by this control and is set using the master AES Level control previously described.
Samp. Rate (Sample Rate)
Configures the Output Sample Rate. Options are as follows:
[48k]
Slaves the output sample rate to the Omnia's internal 48kHz sample clock. To use output
sample rates other than 48 kHz, Input or External sync must be used.
[Input]
Slaves the output sample rate to the sample rate present on the Omnia's AES
digital input. Synchronization is possible over a range of sample rates from 32kHz to
96kHz.
[Ext] (External)
Slaves the output sample rate to the sample rate present on the Omnia's AES
SYNC input. Synchronization is possible over a range of sample rates from 32kHz to
96kHz.
LW Level (Livewire Level)
Adjusts the master audio Output level for the Livewire output which appears on the rear panel
Ethernet / Livewire RJ-45 connector. This control adjusts both the left and right stereo channels
simultaneously.
Right Trim
Allows a +/-3dB adjustment of the right Livewire audio channel gain to correct minor left/right
balance problems in equipment following the OmniaONE. The left channel output gain is not
affected by this control and is set using the master LW Level control previously described.

FM Options

For the transmission side of conventional FM broadcasting, some form of high-frequency boost, or pre-
emphasis is used. The most commonly used values of pre-emphasis are 50 and 75 µs (microseconds). For
North and South America, 75 µs is used. In Europe, Australia and New Zealand, 50 µs is employed. The
factory default pre-emphasis setting is 75 µs. The pre-emphasis selection affects the operation of the audio
processing and is applied to the composite, discrete, and digital outputs. The pre-emphasized signal at the
Left/Right and AES/EBU digital outputs can be restored to flat, if needed, by the De-Emphasis control

There are three choices: Off, 50 µs or 75 µs. Rotate the jog wheel to display the correct
value for your system and click the jog-wheel.
