XYZ Mode
This chapter explains hows to program positions in a 3 dimensional space using X, Y, and Z coordinates.
Once you’ve read it, you should be able to calibrate fixtures for use in a 3 dimensional space, program cues
using XYZ coordinates and transfer a stage show from one stage to another with minimal effort. This
chapter assumes that you have patched the console as covered in the previous chapter.
Programming with XYZ Coordinates
Instead of using pan and tilt values for fixtures, it’s possible to program positions in 3 dimensional space
using XYZ stage coordinates. Why is this useful? Let’s say you wanted to aim 100 fixtures at a specific
point on stage. Normally, you’d have to adjust the pan and tilt positions for those 100 lights individually – a
long and tedious process. In contrast, with the XYZ system, all you have to do is enter the XYZ coordinates
on the parameter wheels and the lights will go there instantly. Likewise, if you need to nudge the lights up a
bit – maybe so they hit the top of a mike stand – you only need to adjust the Z parameter wheel and all the
lights will move there together.
If you’re in a touring situation, then the XYZ system can eliminate the daily task of updating preset
focuses. Instead, just recalibrate the lights and all focus palettes created with XYZ coordinates will now be
adjusted for the new venue.
In order to use XYZ mode when programming, fixtures information must come from either
the built in ROM library or from a ver 3.0 or later library file. See Chapter: Fixture Library at
the back of the manual for more information on adapting old libraries or calibrating
fixtures.
Calibration
The XYZ system must first be calibrated before use. This process is simply a matter of aiming every fixture
at each of four calibration points. Accuracy is quite important, so you may want to iris down the fixtures
when aiming, if possible.
The map below shows the X and Y coordinates mapped onto a stage. Z is the height above the stage.
