Effects
This section describes the effects in the MAC 700 Wash with reference to the DMX channels used to control
them. See page 23 for the complete DMX protocol.
The MAC 700 Wash has two DMX operating modes, 16-bit basic and 16-bit extended. The 16-bit basic
mode uses 16 DMX channels, and 16-bit extended mode uses 23 channels. Extended mode provides all
features of the basic mode plus fine control of the dimmer, cyan, magenta, yellow, CTC, color wheel and
zoom.
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.
Lamp power
L A M P - O N
The lamp-on command on channel 1 strikes the lamp if it is off. If the lamp is on, this command has no
effect.
Note: A peak of electric current that can be many times the operating current is drawn for a fraction of a
second when striking a discharge lamp. Striking many lamps at once may cause a voltage drop large
enough to prevent lamps from striking or draw enough current to trip circuit breakers. If sending lamp-on
commands to multiple fixtures, program a sequence that strikes lamps one at a time at 5 second intervals.
L A M P - O F F
The lamp can be doused from the controller with the lamp-off command on channel 1. The command must
be sent for 5 seconds.
If the lamp-off command is disabled in the control menu (
can still be selected on channel 1 if the following effects are also selected:
• color wheel at slot 1 by sending DMX value 17 on channel 7 (basic mode) or 12 (extended mode)
• beamshaper on by sending DMX value from 1 to 255 on channel 8 (basic mode) or 14 (extended mode)
4 0 0 W A N D 7 0 0 W L A M P P O W E R M O D E S
If full light output is not required, the lamp can be switched to 400 W mode by sending a DMX value from
238 to 242 on channel 1. Running in 400 W mode will significantly increase lamp life.
If the shutter is closed for longer than 10 seconds while the lamp is in 700 W mode, lamp power is
automatically switched to 400 W. When the shutter is opened again, the lamp returns to 700 W mode.
Fixture reset
If an effect loses its indexing and fails to move to programmed positions, the fixture can be reset from the
controller by sending the "Reset" command on channel 1.
If DMX reset is disabled in the control menu (
executed if the conditions listed under "Lamp-off" are met. If it is set to
sent for 5 seconds before it is executed.
Dimming and strobe
The mechanical dimmer/shutter system provides smooth, high-resolution 100% dimming, instant snap open
and snap closed (blackout), random and variable strobe effects up to 10 Hz, and random and variable
pulses in which the dimmer snaps open and slowly dims or snaps closed and slowly opens.
Snap dimming 0-100% or 100-0% is instant. However, because of the way the fixture processes dimming
commands, you need to set effects speed to the fastest speed in vector mode by sending DMX value 3 on
