• DIMMING CURVE provides four dimming options (see Figure 11):

DMX %

Optically linear

- Optically linear – the increase in light intensity appears to be linear as DMX value is increased.

- VRMS linear (S-curve) – light intensity control is finer at low levels and high levels and coarser at

medium levels. This curve emulates the RMS voltage dimming characteristics of an incandescent lamp

such as the tungsten halogen lamp of the Martin™ MAC TW1™.

- Square law – light intensity control is finer at low levels and coarser at high levels.

- Inverse square law – light intensity control is coarser at low levels and finer at high levels.

• FOCUS TRACKING sets focus to automatically self-adjust when you use the zoom effect (see

"Zoom/focus linking" on page 25).

• FOLLOWSPOT MODE enables pan, tilt, or pan and tilt movement to be unlocked so that the head of the

fixture can be directed by hand using a user-supplied handle (see "Followspot mode" on page 25). In

followspot mode the motors can be applied as a brake to pan, tilt, or both pan and tilt movement to prevent

head movement when the fixture is not "manned"; in this case DMX or menu-based control over pan and

tilt is still disabled.

• AUTOMATIC LAMP ON gives three lamp strike options:

- When set to Off, the lamp remains off until a "lamp on" command is received via DMX.

- When set to On, the lamp strikes automatically after the fixture is powered on.

- When set to DMX, the lamp strikes automatically when the fixture begins to receive DMX data, and

lamp power is shut down 15 minutes after the fixture stops receiving DMX data. Automatic lamp strikes

are staggered to prevent all lamps from striking at once. The delay is determined by the fixture address.

No matter what the AUTOMATIC LAMP ON setting is, the lamp can be struck by sending a lamp on

command via DMX on channel 21.

• DMX LAMP OFF and DMX RESET define whether the lamp can be powered off, or whether fixture or

individual effects can be reset by sending a DMX command on channel 21. If either of these settings are

set to Off, you can override this setting and cut lamp power or reset effects by applying a special

combination of DMX values (see "MAC III AirFX DMX protocol" on page 44).

• PARAMETER SHORTCUTS determines whether the gobo wheels and color wheel take the shortest path

between two positions (shortcuts enabled), crossing the open position if necessary, or always avoid the

open position (shortcuts disabled).

• DISPLAY determines whether the display remains on permanently, or goes into sleep mode 2, 5 or 10

minutes after the last movement of the jog wheel or Escape button.

• DISPLAY INTENSITY lets you define the brightness of the backlit graphic display. Select Auto for

automatic adjustment to match the ambient light level, or manually set the intensity to a level from 0% to

100%.

• DISPLAY ROTATION lets you rotate the display manually through 0°, 90°, 180° or 270° so that it can be

read easily no matter how the fixture is oriented. If set to Auto, the MAC III AirFX senses its orientation

and rotates the display automatically.

• ERROR MODE enables or disables error warnings. If set to Normal, the display is activated and lights up

if the fixture needs to report an error. If set to Silent with LED, the fixture does not light the display with

error warnings but error messages can still be read when the display is activated manually. In both

Normal and Silent with LED modes, the status LED in the jog wheel lights amber to indicate a warning

and red to indicate an error.
