Appendix A (Fusion)

Advanced Configuration Reference

This appendix lists the advanced options available when setting up Show Profiles, and the "magic key"
combinations available from the console surface.

Appendix B (Fusion)

Configuring GPIO

The Axia IP-Audio system is capable of transporting routable machine logic along with each audio
signal.
Unlike conventional logic connections which require each command circuit to be wired individually, Axia
sends machine controls over the same Ethernet your upon which your audio travels.
Quasar's GPIO capabilities provide control of external audio devices, logic commands for routine
studio/control room operations such as tally lights, monitor muting, On-Air lights and more, and even
"virtual" GPIO for routing system commands, using Axia Pathfinder routing controls tools.
This Appendix provides a fast overview of these GPIO functions. Please refer to the Axia xNode User's
Manual for more in-depth information on configuring GPIO.

GPIO Port Definitions

Axia PowerStation mix engines feature 4 built-in GPIO connections; Fusion consoles using
StudioEngine mix engines must be paired with xNode GPIO Nodes. Each
GPIO port can be associated with a device in your studio, and provides five opto- isolated inputs and
five opto- isolated outputs per device.
GPIO ports are pre-programmed to support several different types of devices; when you construct
Source Profiles, the GPIO type best suited for the Source Type you choose is associated with that
Profile. When the source is assigned to a console fader, this Source Profile selection tells the GPIO port
what sort of command to send to the attached device.
If the Source Profile defines the attached device as a microphone, the GPIO port sends logic for On,
Off, Remote Mute and Remote Talk commands on the appropriate pins. If the Source Profile is configured
for a line input, the GPIO port sends Start, Stop and Reset commands, plus closures for Ready lights, etc.
Axia GPIO ports can deliver unique command sets for the following types of devices:
1. Microphone (Operator, Guest or Producer)
2. Line Input
3. Codec
4. Telephone Hybrid
5. Computer Playback Device
6. Control Room Monitor
7. Studio Monitor
8. Accessory Button Panel Device
