Euphonix Max Air Mixing Console Operation Manual
Chapter 11:
The event system can program many Max Air features. For example:
• use a fader to start a cart machine or turn speakers on/off;
• use Custom key to recall a Layout and Snapshot together;
• use an external GPI to automatically track a source (audio-follow-video).
An event consists of a set of input conditions governed by a logical operator. When the
logical state of that input set equals "true," a set of output actions are activated. Inputs
may be surface parameters (i.e., channel on, fader, Custom keys, etc.) or external inputs
via the GP132 GPI. Outputs may be Max Air parameters or external relay outputs via
the GP132.
GP132
The GP132 (Relay Box 132 General Purpose Interface) is used to communicate to de-
vices that use tallies and relays. The following special considerations should be noted
when using the GP132:
• MIDI cables are used to connect GP132 to Max Air. The MIDI specification for
maximum cable length is 10 m. Cables over this length may cause data loss.
• If power fails on the GP132, none of the relays will function. After restoring pow-
er, the GP132 resets ALL relays.
• Refer to the Max Air Installation Guide for proper GPI input and output wiring
instructions. Note that in many cases an external power supply will be required to
activate GPI inputs.
