Omnia 6 Use and Installation Guide – Version 1.00a

When power is first applied, it takes approximately ten seconds to load the DSP code from the rear-panel PCMCIA
memory card. During system power-up, the front panel LCD screens display several status screens while the
operating software and DSP code is loaded. Once the main Omnia-6fm Main Menu is shown on the right screen, and
the Meter Screen is shown on the left display, the unit is ready for use.
Rear Panel Connections
Audio Inputs—Analog & Digital (Female XLR)
Balanced XLR-type connectors are used as input connectors for both the analog and AES-3 digital audio. Both
analog and digital input sources may be connected simultaneously, however, only the input source that has been set in
the Input menu is active. Analog/Digital Input source selection is done through the
Input Source
software parameter
setting in the Input Menu.
The stereo analog inputs are designed for st4 dBu balanced signals. Pin 2 is Hot. The digital AES-3 inputs
(IN and EXT. SYNC) accept any sampling rate between 32 and 96 kHz. No user adjustment is necessary on the AES
input since a high-quality sample rate converter is built into the unit. Individual channel gain and level setting for
both analog and digital is done using the
Input Gain
software parameter settings in the Input Menu.
A Note About Relative Phase:
If the relative phase of your installation (including the Omnia-6fm) differs from that
of your existing system, your announcers may feel that they sound “weird” in their headphones. If this occurs, then
the relative phase of the processor is 180 degrees from what your air talent is used to. To remedy this, you can either
reverse the polarity of both of the analog inputs or change the
Invert Both
software parameter setting in the Omnia-
6fm Input Menu.
Audio Outputs—Analog & Digital (Male XLR)
Individual Left and Right analog outputs are available on two male XLR jacks, as is a stereo digital AES-3 output.
The digital output (with selectable output sample rate) is produced directly from the output of the final processing
section. The analog output is derived from a D/A converter driven from the digital output.
Note:
Both the analog and digital AES-3 outputs are always active and can be used simultaneously.
