5.1 General Purpose Input / Output
The module has several features for remote controlling / signaling. All general purpose in- and outputs are
under software control and used in various ways.
ON, CUE, COMM switches and fader functionality can be set-up to trigger one or multiple GPO’s on the
module, studio-mutes, red-lights and local or global cue-resets.
GPO’s can send out a pulse or a continuous signal when triggered. Pulses can be generated by on, off or
both.
The module has four GPO’s. When properly connected to an AirMax patch-panel all GPO’s are
connected to one of the Remote jack connectors between the Tip and Ring. By opto isolated relays the
GPO’s are able to handle a maximum of 50 V at 200 mA.
GPI’s can be set up to trigger ON, CUE, Cough/Mute and COMM. GPI’s can be switched between
latching or momentary, but when selected the AirMax has the ability to figure this out by itself.
The module has two GPI’s. When properly connected to an AirMax patch-panel all GPI’s have a 5 V
TTL 100 kOhm circuitry connected to one of the Remote jack connectors between the Tip and Ring.
The module has one MIC GPIO containing a MIC-ON output and a control input on one stereo jack.
Tip =LED
Ring =Switch
Sleeve =GND
All these settings are made per individual input, serving different purposes depending on the actual
audio source.
