16 MAC Aura user manual

Operation and effects

Warning! Read “Safety Information” starting on page 3 before installing, powering, operating or

servicing the MAC Aura.

See “DMX protocol” on page 22 for a full list of the DMX channels and values required to control the

different effects.

Effects

Beam and Aura

The MAC Aura has two LED arrays:

• The Beam: the LEDs that provide the main output, and

• The Aura: the secondary LEDs that illuminate the front of the head, provide local diffuse light output and

can be set to contrast with the Beam output.

See “Beam, Aura and FX control” on page 13 for full details of these modes and how to set them up.

Shutter effect

The electronic ‘shutter’ effect available for the Beam and the Aura provides instant open and blackout,

variable speed regular and random strobe and opening/closing pulse effects as well as burst and sine wave

effects.

Dimming

Beam and Aura intensity can be adjusted 0 - 100% using electronic dimming. See the available dimming

curve options in “Dimming” on page 15.

Zoom

The Beam can be zoomed from 58° to maximum (narrow) 11° one-tenth peak angles.

Aura output is automatically dimmed as the zoom approaches maximum. There is a linear dimming curve

from normal Aura output when the Beam is at 90% zoom, to zero Aura output when the Beam is at

maximum (narrow) zoom.

Pan and tilt

The MAC Aura’s moving head can be panned through 540° and tilted through 232°. The speed of pan/tilt

movement can be adjusted on the DMX fixture control channel 8 and in the fixture’s onboard control panel.

Both

EXT and STD control modes offer fine control of pan and tilt. In each case, the main control channel

sets the first 8 bits (the most significant byte or MSB), and the fine channel sets the second 8 bits (the least

significant byte or LSB) of the 16-bit control byte. In other words, the fine channel works within the position

set by the main channel.

Controlling color

Color wheel effects

The electronic ‘color wheel’ effects available for the Beam and the Aura give the convenience and feel of a

mechanical color wheel and let you snap between 33 different full LEE-referenced colors. You can also

scroll continuously forwards or backwards through the colors or display random colors at variable speed.

The approximate RGB equivalents of the ‘color wheel’ colors are given in “LEE colors and RGB equivalents”

on page 28.
