The Gain slider controls the input level into the recorder. If, for example, you are recording
from the MPX patch point with this control set at -­‐3dB, you will get a -­‐3dB peak MPX file,
suitable for use in a modulation monitoring software program such as MpxTool.
If you are recording directly from the Omnia.9 unit or on a remote computer with a high
speed connection to Omnia.9, the Source window will show “PCM,” indicating the recording
will be an uncompressed PCM wave file. If you have a slower remote connection, the
window will show “Vorbis” indicating that the file is being recorded in a compressed (lossy)
format. In either case, the recorder always produces a FLAC (Free Lossless Audio Codec) file.
The Minimize File Size control automatically adjusts the recording resolution to match the
actual noise floor of the audio, allowing you to record a full hour of off-­‐air MPX audio in a
file size of only 500mb.
You also have the option to use Omnia.9’s Time-­‐Based File Splitting feature, which allows
you to record files of a specified length (15 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, or
4 hours). As it is sample-­‐accurate, you can splice the files together after recording if you
like. There is no file limit size (other than the amount of space on your external drive) so file
splitting is not required, only an option.
Time/Date Menu
The Time/Date menu has three sub-­‐menus for setting Omnia.9’s internal clock.
The Time Zone menu allows you to choose the proper time zone for your particular
geographical area. Daylight Savings Time is automatically applied in applicable time zones.
The NTP menu contains the addresses for five Network Time Protocol servers. When
enabled, NTP Synchronization will use one of these servers to keep the Omnia.9’s clock
synchronized.
The Set Clock Manually menu contains the controls for manually setting the time and date.
Selecting the Update Time Sliders or Update Date Sliders buttons will refresh the time
displayed on the sliders. Use the Set Hour, Set Minute, Set Second, Set Year, Set Month,
and Set Day sliders to reflect the current time and date, then select Apply Time or Apply
Date to put the new values you’ve set into effect.
System Configuration Menu
The System Config menu contains the controls to select an internal sample rate, set a system
password, establish an IP “white list” for remote HTTP access, assign an IP address to the unit,
determine how many processing cores are available, and how many streaming encoders of each
variety are available. You can also check the software and GUI versions, save your custom
configurations to a USB drive, update to the latest software versions, and, if you purchased an
Omnia.9 without the additional HD and streaming capabilities, upgrade to the full multi-­‐cast version
from this menu.
