GPI Menu
The
GPI Menu enables an Engineer or Technician to select whether GPI inputs respond to
Latching or Momentary closures from external devices. The GPI connector can be used to Cut/Dim
the internal and external Loudspeakers, recall
Home preset and to recall User presets 1 to 7. The
pin-out is described in Section 3.5.
In
Momentary Mode , Dim and Cut GPI's latch in a toggle manner, i.e. one closure to ground
toggles the function ON; the next ground toggles it OFF. In an ON state; the GPI pin is driven low
to allow an LED to be fed from the port. This LED drive is briefly pulsed high at about 100Hz to
allow the port to be read whilst it is driving.
The preset recall GPI’s in ‘Latching’
mode are mutually exclusive.

Internal / External Loudspeaker Mute
The
AVM-T-MIX is designed to be used with either Internal or External Loudspeaker Systems .
Users may wish to define User Preset conditions which associate the operation of the unit with
internal speakers for in one state and external speakers in another. To facilitate this kind of hybrid
operation the
AVM-T-MIX is equipped with individual Loudspeaker Mute buttons which can be
configured with different functionality dependant upon their desired use and then saved to
individual presets.
In the event that
AVM-T-MIX is installed for use with external speakers only with the intention to
mute the internal speakers, a DIP switch on the rear panel can be used to override the Internal LS
Mute button in Setup 2 Menu .
