5.15.2 Automatic Preset Recall tab
AMX-3981 offers the user the possibility to select a user
preset based on the status of the incoming audio.
Access to the User1 and User2 presets can be triggered
automatically when specific combinations of input audio
signals are detected at the AMX-3981 input.
Switching card parameters in mid-program is more complex
than switching them manually in an off-line situation because
of the need to minimize or eliminate any transition effects,
and is generally quite specific to the card configuration and
the audio modules that are installed. Because of this, a fully
automatic configuration of the feature is not possible, and
user involvement is required. Set-up instructions are given
below.
The Automatic Preset Recall (APR) feature uses the status
of audio appearing at the input audio channels to determine
whether activation of a preset is required.
The user selects whether to use the 16 embedded audio
channels, or the 8 discrete AES audios in the process, using
the radio buttons in the Input Audio Selection section of the
panel.
The user specifies the combination of audios that must
appear on all 16 channels using a concise Presence/Type
string notation in a data box, one for each of the two user presets.
• For reference, the current input Presence/Type string is shown in a data box.
• The current input status for each channel is also displayed in a color and text graphic.
