The AFD presets button allows the user to save
commonly-used selections under descriptive names,
making it easy to recall and load selections for specific
situations. The name of the current preset is displayed.
• Type a name in the Preset Name box and click Save
to save the current Mode and Aspect Ratio settings
under this name. The newly-saved layout is also
loaded (see below) when the save command is
selected, so its name will be shown in the Current
Preset box beside the AFD Presets button in the
Output AFD window.
• Click a name in the list to select it, and then click Load
to configure the AMX-1881 to send that AFD flag.
To see the mode and value saved in any Preset, click the
Info button to the right of its name to open the Parameters
window:
Input error
In the event of an input failure, activating the auto black
feature will replace the video input with a locally generated
video black in order to maintain audio embedding.
Test
The test menu allows the user to enable test signals on the
AES and video outputs for troubleshooting purposes.
Notes:
1. If an AES checkbox is enabled, the corresponding
AES channel should be used as a source for
embedding in an audio group. Set this in the Audio
Insert section of the Audio panel’s Embedding tab.
(See page 9)
2. LTC timecode insertion should be set to ON in the
Metadata / LTC panel in order for the timecode to be
embedded. (See page 10)
Factory
Clicking the Load Factory button will restore all of the
adjustable parameters to a factory-preset state. Those
preset settings are indicated by an underline in the AMX-
1881 menu on pages 4 to 6 of this manual.
Alarm Config
See Annex 2 on page 15 for details.
