Fixture ID
The MAC III AirFX lets you set a four-digit ID number to ease identification of the fixtures in an installation.
When a fixture is powered on for the first time, it displays its DMX address by default. As soon as you set an
ID number other than 0000 in FIXTURE ID, the MAC III AirFX will display this ID number by default.
To let you distinguish easily between ID numbers and DMX addresses, the ID number is always displayed
with four digits and DMX address is displayed with between one and three digits.
Personality – tailoring performance
The MAC III AirFX provides several options that let you optimize the fixture for different applications in the
PERSONALITY menu:
• The PAN/TILT SETTINGS menu gives three options:
- PAN/TILT CONTROL lets you swap and/or invert pan and tilt and activate the pan and tilt limits you
define in PAN & TILT LIMIT SETTINGS (see below).
- MOVE ON RESET lets you choose if you want pan and tilt to move when the fixture resets or not. Pan
and tilt movement can be a useful visual sign that fixtures in a rig are powering up and resetting.
- PAN & TILT LIMIT SETTINGS lets you define minimum and maximum limits for both pan and tilt
angles, making it possible to install fixtures close to obstacles such as other fixtures with no risk of
collision. Settings are based on the following principles:
Pan range for pan limit purposes runs from 0° to 360° clockwise as seen looking at the fixture from
the bottom of the base towards the yoke, as if the fixture was hanging downwards underneath you.
Tilt range is +134° and -134° either side of 0°, which is the head straight up position with the front
glass pointed directly away from the base.
The light beam points fully forward (the front of the fixture is indicated by the arrows printed under the
base) when pan is set to 90° or 450° and tilt is set to +90°.
Selecting Inside keeps pan and tilt inside the limits you set – i.e. angles define a 'safe zone'.
Selecting Outside keeps pan and tilt outside the limits you set – i.e. angles define a 'no-go zone'.
Limits are not activated until the head is panned and tilted into its safe zone or out of its no-go zone.
When pan/tilt limits are active, the PAN/TILT light at the bottom right of the display lights yellow.
See Figure 10. To limit pan so that it stays inside a safe zone 20° either side of fully forward and limit tilt so
that it stays inside a safe zone 18° either side of fully forward, for example:
1. Set PAN MINIMUM to 70°.
2. Set PAN MAXIMUM to 110°.
3. Set TILT MINIMUM to +72°.
4. Set TILT MAXIMUM to +108°.
5. Set P/T LIMIT AREA to Inside.
