Timing Channels - ETC Source Four Revolution User Manual

T i m i n g C h a n n e l s
Three timing channels are provided: Focus Timing (Channel 9), Color Timing (Channel 10),
and Beam Timing (Channel 11). These channels can be used to communicate the desired
duration of a movement at the same time you communicate the destination of the
movement. The instructions below describe the general method of using a timing channel.
Specific instructions for recording cue fade times or part cues can be found in your control
console's user manual.

The Fan Speed Control Channel (Channel 14) allows fan speed control for quieter fixture
operation. As long as this channel is at 0%, all fans will run at full speed for maximum
cooling. Setting this channel at incrementally higher values lowers the fan speed
incrementally.
For example, 25% = 75% fan speed, 50% = 50% fan speed, 75% = 25% fan speed, and so
on. Setting this channel at 100% will turn the fans off completely for silent operation.
Temperature sensors in the Revolution sense if fans are required to keep the fixture from
an over-temperature condition. These sensors override the fan speed channel and cause
the fans to operate to prevent over-heating, regardless of the channel setting.
For longer gel string life—especially saturated colors—keep the fan speed as high as
possible, that is, a lower value for channel 14.

Setting the Focus Timing Channel (Channel 9) at 100% provides more responsive manual
control of Revolution parameters. Remember to restore this channel to 0% (or the desired
timing speed value less than 100%) for smoothest cue playback operation.
N o t e :
Playback of cues with the Focus Channel set at 100% may result in less than satisfactory
luminaire movement.

Determine which timing channel controls the parameters you want to affect (see
Control, page 10).
Set the timing channel to the appropriate value. Each step of DMX equals one
second of time. Percent-based consoles will have a granularity of ~2.5 seconds
per step. The maximum timing value is 4 minutes 15 seconds.
Record the parameter channels and their corresponding timing channel into a
cue or cue part with zero fade timing. Avoid placing timing channel moves within
a cue or cue part that contains a fade time other than zero. Fading a timing
channel and its corresponding parameter channels can create unexpected
luminaire behavior.
Repeat for other parameter channels and timing channels as needed.
