Enabling the Orban Audio Processor for Preset Selection
Enable the Orban audio processor to allow preset selection using either the controller UI (see Orban
Enabling - using the Controller UI ) or the AUI (see Orban Enabling - using the AUI - see page 3.2.201 ) as
follows:
NOTE
: Enabling the Orban audio processor locally will cause the AUI to display an enabled setting. The
same occurs on the controller UI when enabling via the AUI.
Orban Enabling - using the Controller UI
1. With the transmitter turned on and in local mode of operation, navigate to the controller UI's
Main Menu -> User Settings
menu. Select
Edit Presets
(see A in Figure 3.2.170 on page
3.2.200 ).
2. In the
Edit Presets
screen (see B in Figure 3.2.170 on page 3.2.200 ), select from the list the desired
preset for use with the Orban audio processor or create a new preset.
3. Within the selected preset's screen (see C in Figure 3.2.170 on page 3.2.200 ), scroll down and
select
Main Audio
.
4. Within the
Main Audio
screen (see D in Figure 3.2.170 on page 3.2.200 ), scroll down and select
Audio Processor
. This option appears only when the transmitter has been configured for Orban
Inside.
5. Within the
Audio Processor
screen (see E in Figure 3.2.170 on page 3.2.200 ), select
Enable
. From
the
Enable
screen, select
ON
to enable the audio processor (selecting OFF disables the audio
processor)
NOTE
: The Orban Inside card processes only the main audio; however it is possible for the composite
SCA inputs to result in excessive modulation. The L/R limiter is automatically disabled when the Orban
Inside card is selected; however the other limiters (hard limiter, AGC limiter, 2-slope limiter) remain
active. Nautel recommends that you set the thresholds for these other limiters high enough to ensure
the signal is unaffected. These other limiters remain as a last resort to prevent over-modulation.
