Proportional Levels

Proportional patching is an advanced feature which when applied correctly
can be very powerful. Proportional patching works very similar to a more
familiar concept of proportional submasters. With submasters, channels are
patched to the submaster at varying levels. The submaster controls those
channels from 0 up to the channel max all at the same proportional rate.
For example, imagine a situation where you have two fixtures both aimed
at the same area. Since both fixtures always work together, you've decided
to patch them into the same control channel. Suppose for a moment
though that one of the fixtures has a significantly shorter throw than the
other fixture. The result is that one fixture is brighter than the other.
Proportionally patching can fix this problem. You can patch the brighter
fixture at a lower level to the same control channel as the other fixture.
When done correctly, both fixtures will be the same brightness. This is only
one example of proportional patching, there are many other uses for this
feature.
When you assign a proportional level to a dimmer, it limits the maximum
output of the dimmer to the percentage specified. For example, a dimmer
assigned a proportional level of 50% never exceeds 50% output level, even
when the channel controlling that dimmer is at Full. In this case, a channel
level of Full provides 50% dimmer output. The same control channel at
50% would provide a dimmer output of 25%. Proportional level
assignments are shown in the third column of the patch display labeled
"%".
Follow these example steps to patch channel 2 to dimmer 5 at 50%:

Use the [AND], [MINUS]
and [THRU] keys for multiple
dimmers.
You can also press the
