26
corresponds to a nominal average program audio input level of +4 dBu. To change input level, rotate the jog-
wheel to adjust the level in 0.1 dB steps. The
Input Master
affects both the left and right inputs simultaneously,
while the
Right Trim
only affects the right channel over a +/- 3 dB range. Use the level bargraphs to make this
adjustment so that signal peaks read a bit higher than -15 dB with normal program audio. 0 dB corresponds to 0
dBFS (decibels below Full Scale digital, i.e. the digital clip point) so be sure that peaks do not reach 0 dB
regularly or distortion will result.
Input Phase:
If the relative phase relationship of the Omnia-3 is different from your existing system, it could
cause your announcers to think they sound “weird” when monitoring through the system using their
headphones. If this happens, the relative phase of the Omnia-3 is 180 degrees different from what your
announcers are used to. To remedy this, you can reverse the polarity with this menu selection. This is the same
as but much more convenient than swapping pins 2 & 3 on both L & R input XLR connectors!
Output Levels
The am and net styles have two parameters are under this sub-menu item:
Output Left
and
Output Right
. The
fm Turbo style has
Output Master
and
Right Trim
, instead.
Adjustment of the left/right audio levels is done in the same manner as setting the input levels. Since these
settings take place before the D/A converter, the settings affect both digital (AES/EBU) and analog XLR
outputs. In Omnia-3fm Turbo units, the composite MPX outputs are not affected by these controls.
Note:
Both the analog and digital AES/EBU outputs are active at the same time. Connections can be made
simultaneously to the analog and digital outputs, as well as the composite outputs on the Omnia-3fm Turbo.
Input Source
Selects whether the input is supplied by the
Analog
or
AES/EBU
digital input.
Mono Mode
This sub-menu has five items:
Stereo
,
Mono L
,
Mono R
,
Mono L+R
and
Swap
.
The
Stereo
selection indicates that the processor will process a 2-channel stereo signal. Please note that the two
channels cannot be separate un-related signals since the processing is stereo strapped.
Mono L:
The signal at the left input is fed to both the left and right channels of the processing.
Mono R:
The signal at the Right input is fed to both the left and right channels of the processing.
Mono L+R:
A sum of the two input channels is fed to both left and right channels of the processing.
Swap
is similar to
Stereo
but the L & R channels are reversed. (swapped)
