16 MAC 301 Wash user manual
DMX operation
Warning! Read “Safety Information” on page 3 before installing, powering, operating or servicing
the MAC 301 Wash.
This section describes only DMX control features that require particular explanation. See “DMX protocol” on
page 22 for a full list of the DMX channels and values required to control the different effects. See “Effects”
on page 15 for a full description of the fixture’s effects.
8- and 16-bit Standard and Compressed DMX control modes
The MAC 301 Wash has four DMX operating modes:
• Standard 8-bit uses 16 DMX channels
• Compressed 8-bit uses 12 DMX channels
• Standard 16-bit uses 19 DMX channels
• Compressed 16-bit uses 15 DMX channels
In Compressed modes, the color wheel, pan/tilt speed, effect speed and movement blackout channels are
not available. This means that color can be changed using the RGB channels only.
The 16-bit modes include the same control options as 8-bit modes but fine control of RGB is added on 3
extra channels.
Where fine control is available, 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.
Color control and CTC using DMX
The MAC 301 Wash has a color wheel effect channel, RGB color mixing channels and a CTC channel.
The color wheel effect channel is only available in 8-bit and 16-bit standard modes. In compressed modes,
you can only control color with the RGB channels.
The color wheel effect channel that is available in standard modes has priority over the RGB channels. If
you want to use the RGB channels in standard modes, you must set the color wheel effect channel to DMX
values 000 - 001.
The CTC channel can be used to adjust white color temperature both when using the color wheel effect and
RGB control. The CTC adjustment range available depends on the fixture’s white balance setting. If white
balance is set to 6500 K, you can reduce color temperature to approximately 2800 K.
Color balance using DMX
The control channel (DMX channel 5 in all DMX modes) lets you adjust color balance as follows:
• DMX values 000 - 007: Unbalanced mode, full power on all RGB strings.
• DMX values 008 - 015: White balance approx. 8500 K. Marginally reduced intensity of the RGB strings.
Can be used to balance the color output of different MAC 301 Wash fixtures.
• DMX values 016 - 023: White balance approx. 6500 K. Definite reduced brightness in blue. Possible
reduced brightness in green and red. Can be used to balance the color output of different MAC 301 Wash
fixtures. If all RGB channels are set to 100%, you should obtain a good general-purpose white color
temperature.
• DMX values 024 - 031: White balance the same as for DMX values 016 - 023, but the RGB curve is set to
linear. This setting lets you use the color picker function on several lighting consoles.
The color balance selected on channel 5 applies when using both the color wheel effect and RGB to control
color.
