MAC 401™ user manual
DMX channels used by CT Zoom module
The following table gives an overview of the control menu settings available and number of channels used in
the various modes available in the CT Zoom module.
Tailoring performance
The following performance options are available in the
PERS
menu.
Pan and tilt movement
The MAC 401 provides several options for optimizing movement for different applications.
• Pan and tilt speed can be set to normal or fast with the
PTST
-
PTSP
command.
• The
PINV
and
TINV
commands invert the direction of pan and tilt and the
SWAP
command sets pan
commands to tilt and vice versa. These settings are useful for symmetrical effects with multiple fixtures.
Resetting via DMX
By default, it is possible to reset the whole fixture, reset pan and tilt only or reset effects only by sending a
DMX command on the Fixture Control DMX channel (the last of the channels used). This feature can be
disabled (to avoid accidental resets in the middle of a show, for example) and enabled in the
DRES
submenu.
If the DMX reset feature is disabled in the
DRES
submenu, it is still possible to override this setting and
reset the fixture via DMX by sending DMX value 232 on channel 2 and DMX value zero on channel 1 before
applying the reset command on the Fixture Control channel.
Cooling
The
FANS
submenu gives you a choice of three cooling fan settings:
• The default setting
REG
sets fans to temperature-regulated operation. This setting should suit use in all
normal situations and ensure excellent service lifetimes for all components.
• The
FULL
setting maximizes cooling and reduces the operating temperature of the components in the
head. It is recommended when the MAC 401 is used intensively in a warm environment or in fixed
installations. Note that this setting will give increased fan noise compared to temperature-regulated fan
operation.
• When the
SLNT
setting is selected, Silent mode is activated and head fan speed is reduced to minimum.
The base fan will still run. Maximum values allowed for RGB or HSV will be limited (no matter what
operating mode is selected), so that less heat is generated. If the LEDs get too hot the fans will revert to
Regulated mode. When the LEDs are cool enough the fans shift back to Silent mode. The color wheel
channel has lower intensity when Silent mode is engaged.
