Triming a S4

Hey,

So a few months ago I had a TD for a dance show through and he showed me a way to basically "reset" the trim on the S4 without having to mess around while the lamp is on. Of course I was tired and now when I am getting ready to do some lamp TLC (students can really mess up the trims and if I have to go through and trim ever lamp live it's going to take a long long time). I was wondering if anyone else knows of the "trick".

Thanks.

If there is a ‘trick’ without turning ONthe light I would be very surprised. The reason you need to adjust the lamp is due to the filaments ‘sagging’ over time and needing to be re-adjusted to the correct focal point within the reflector. The lamp needs to be ON in order to do this.

When ETC hung over 200 lights in the atrium of Town Square in Middleton, I helped Fred Foster bench focus all the units. It is the best way to get flat fields…so if there is a trick…Fred was not using it J

This would be a good idea for a video. Especially if Fred was to demonstrate the process.
