7.1 General Purpose Input / Output
This module has several features for remote controlling / signaling. All the general purpose in and outputs
are under software control and can be 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 two GPO’s. When properly connected to an AirMax patch-panel all GPO’s connect to
one of the Remote jack connectors between the Tip and Ring. By way of 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 on itself.
The module has three GPI’s. When properly connected to an AirMax patch-panel two GPI’s have a 5 V
TTL 100 kOhm circuitry connected to one of the Remote jack connectors between the Tip and Ring.
The third GPI is an internal GPI, which signals when someone is trying to call you.
All these settings are programmed per individual input, serving different purposes depending on the
current audio source.
