Headphones

A high-power, overload protected headphone output is available on the front

panel for local monitoring. The headphone audio source can be selected in

software to be from several signal points within the processing algorithm,

including both analog and AES inputs even if those inputs have not been

selected to feed the audio processing chain.

Network Connections

AirAura contains two methods of remote connectivity:

• Wired Ethernet via twin 100Base-T Ethernet ports on the rear

panel. These ports are Auto MDIX and therefore each port will

accept either a straight through or crossover cable in any

combination.

• 802.11b/g compatible wireless interface. This interface is

configured to make AirAura appear as an ad-hoc wireless device,

providing the simplest method for connecting for most end users

and operating systems. Security options are available in the

wireless interface configuration to allow password protection if

desired. Because AirAura doesn’t contain anything that would be a

desirable hacking target we configure the interface with no security

as the factory configuration. Please see the appendix for detailed

programming information for the wireless interface.

General Purpose Interface (GPI/GPO)

AirAura is equipped with eight General Purpose Input (GPI) control input ports on

one female DB-9 connector, and four General Purpose Output (GPO) tally

outputs on a second female DB-9 connector. All GPI and GPO connections are

optically-isolated from AirAura’s internal circuitry to prevent external ground loops

and to prevent dangerous voltages from being introduced into AirAura.

The eight GPI inputs are hard-coded in software to activate the first eight preset

slots.

Note that as of this writing (Version 0.2.0 software) the GPO ports on AirAura are

disabled pending new features. Please see Appendix E for connection diagrams

and other data concerning the use of the GPI/GPO ports.
