77.CTS

The MAC 2000 Wash is compatible with USITT DMT-5-2 controllers. The fixture has two DMT operating
modes, 8-bit and -6-bit. The -6-bit mode re_uires two more DMT channels than 8-bit mode but provides
more precise pan7tilt positioning. All other functions are identical. See nDMT protocolo on page 29.

Color

The color mixing system uses continuous dichroic cyan, magenta, and yellow ZCMY[ color filters. It is a
subtractive system that removes color from white light. Inserting all three filters results in loss of light: for
maximum brightness, mix 2 colors at a time.
In addition, two color wheels are provided, each with four removable positions for dichroic glass color filters
and a position for a direct pass through of the beam.

Dimming and strobe

Two dimming systems are available - a built-in mechanical dimmer7shutter and an optional dimmer wheel
Zorderable separately[.
Shutter
The mechanical shutter system provides full-range -00 percent dimming, instant open and blackout,
random and variable strobe effects up to -0 HV, and random and variable pulses in which the dimmer snaps
open and slowly dims or snaps closed and slowly opens. Two dimming curves are availablem one that
simulates a tungsten lamp and another that provides linear dimming Zsee nShutter dimming curveso on
page -3[.
+ptional dimmer wheel
A separately orderable dimmer wheel ZP7N 623240-8[ that provides enhanced dimming can be installed in
place of color wheel 2. The dimmer wheel uses a logarithmic algorithm that, compared with the dimming
available from the shutter system, enables much finer and smoother dimming at the bottom end of the
dimming range.
If you use the dimmer wheel, it is recommended that you do not use the shutter system to control intensity,
and that the shutters be set to fully open Zensure that 255 is the default DMT value issued on the shutter
intensity channel from your controller[. You can continue to use other shutter effects, such as the strobe.
The wheel is detected automatically by the fixture when installed. The installation procedure is described in
nInstalling the optional dimmer wheelo on page 22.

Color temperature correction

The color temperature correction ZCTC[ system uses a continuous 0 - -78 mireds color filter that lowers the
color temperature from 6000 c to 2900 c.

The Voom lens widens the beam from --\ at full spot to 40\ at full flood with the standard lens and aperture
ring fitted.
