Protection Limiting Menu; Loudness Menu - Omnia .9 Installation & User Manual

MONITOR OUTPUT MENU

Protection Limiting Menu

The Bass Limiter Threshold controls for the Left and Right channels set the threshold of the bass limiters. The (Coupled)
control lets you move both Left and Right together, or you can use individual L / R controls to balance the two channels. Keep in
mind that these controls affect only the monitor output audio and have no effect on any of the on-air processing cores, but they are very
useful when pushing higher volumes and more bass through very small speakers.
The Limiter Threshold controls for the Left and Right channels set the threshold of the Protection Limiters in each Monitor
Output section and operate in the same manner as their counterpart in the HD (and other non-FM) Processing cores. As with
the Bass Clip Threshold controls, only the monitor output audio is affected.

Loudness Menu

The Loudness menu allows you to automatically change the equalization of each monitor output depending upon the volume
level. This is similar to the traditional "Loudness" adjustment found on many car audio systems as well as on some home
systems and TV sets. It only affects the speaker outputs and does not affect the on-air audio of the Omnia 9.
Speaker calibration, which is covered in greater detail later in this manual, is normally done at relatively high volume levels
in order to provide adequate gain into the mic to overcome room noise. Normal listening levels may be substantially lower.
While the EQ curve of the output of the speakers technically remains the same, the way our ears perceive different frequencies
at lower sound levels will cause the audio to sound different. Specifically, lower and higher frequencies will sound softer than
mid-range frequencies.
Do not be alarmed if you find you need to add several decibels of low-frequency boost (at a very low frequency and a width of 3.0
octaves or so) in order for the bass to sound balanced at lower volumes. The same is true for higher frequencies, but normally a dB or
two is sufficient (perhaps at a very high frequency with a width of 2.0 octaves or so).
The Frequency, Width, and Gain sliders operate in the same manner as their counterparts in other sections of the
♦
Omnia.9 in which a parametric equalizer is offered.
