A while back I acquired a dirt-cheap secondhand pair of SoundLAB Gyroscan units (G017X) for use on-stage as spotlights in combination with my ENTTEC DMX-IS computer-controlled DMX interface. The idea being that I can set them up for each song, mark a cross on the stage and that’s where the singers stand – cheap computer-controlled spotlights, yay.
There’s a couple of gotchas with this:
First, the Gyroscan DMX interface is inverted – that is to say, hot/cold are the wrong way round on the DMX pinout. While professional establishments tend to have DMX inverters to sort this stuff out I didn’t have any and it seemed to be a simple matter of popping the back off the unit and swapping the cables around. Ten minutes with a soldering iron and we’re in business.
Second, there’s no DMXIS fixture file which will deal with them properly. The Prosound Smart Scan II file comes close but wastes a few (possibly precious) channels which makes it unsuitable if you want everything on one screen. Thus I’ve put a DMXIS fixture ‘macro’ together which if you’re using Windows you can save in C:Program FilesENTTECDMXISDmxLibrarySoundlab and it’ll automatically find it:
This seems to work fine for me and also makes the positioning trackpad work in the bottom left corner of the DMXIS control panel.
The only real comment I have on the Gyroscan units (bear in mind here I’m still an amateur at this) is that they’re a bit slow to cue up a gobo. Other than that they seem fine!
