Effects
This section gives details of the effects available in the MAC Aura PXL lighting fixture. See the DMX protocol
tables starting on page 22 for details of the channels and commands used to control the effects via DMX.
Effects control
Where fine control is available, the main control channel sets the first 8 bits (the most significant byte or
MSB), and the fine channels set 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 coarse channel.
When the MAC Aura PXL is included in a Martin P3™ system, the fixture’s 19 Beam pixels and 141 Aura
pixels can be mapped to a video source (such as a media server) that is connected to the P3 system
controller.
P3
The MAC Aura PXL is compliant with the Martin P3™ system controller family. If you add the fixture to a
P3-driven installation, the P3 system controller will map the fixture’s 19 Beam pixels and 141 Aura pixels
individually regardless of which DMX mode the fixture is set to. This means that, even if the fixture is set to
Compact or Basic DMX Modes, the video fed into the P3 system controller will be mapped onto every
individual pixel in the fixture.
P3 control lets you match the color and intensity of MAC Aura PXL fixtures precisely and instantly with other
P3-compatible lighting fixtures, creative LED elements or LED video panels in an installation.
Control protocol priority
The MAC Aura PXL auto-senses and responds correctly to whichever control protocol it is receiving: DMX
and/or RDM via standard DMX cable, DMX and/or RDM via Art-Net or streaming ACN over Ethernet cable,
or P3.
If the fixture is receiving both P3 data and DMX data, which can be either:
• via a combination of DMX cable for DMX and Ethernet cable for P3, or
• from a P3 system controller that is merging DMX and P3 data and sending it via Ethernet cable,
the P3 mix channels for the Beam (channel 18) and Aura (channel 32) let you determine which signal
should take priority. You can also crossfade, which means that you can superimpose DMX data with variable
opacity from 0% to 100% onto the P3 video output that is being displayed on the fixture’s pixels.
Merging global and pixel-level color control
In Extended and Ludicrous mode, the color of the 19 beam pixels can be controlled by both the Beam global
RGB control (channels 4 - 9) and the Beam pixel RGB controls (channel 33 - 89).
In Ludicrous mode, the color of the 141 Aura pixels can be controlled by both the Aura global RGB control
(channels 27 - 29) and the Aura pixel RGB controls (channels 90 - 512).
Global color control is combined with pixel-level color control using HTP (highest takes precedence) logic.
So, to control color on a global level, keep the pixel RGB channels at zero. And to control color
pixel-by-pixel, keep the global RGB channels at zero. For more advanced looks it is also possible to use a
mix of both control methods (for example: set background color with global RGB control and overlay pixel
effects with pixel RGB controls).
