Question about screen type

[Harold Hallikainen]

I wish the LSS-200 were still in production. With a test show, it measures screen luminance and chromaticity. It also measures the SPL from each audio channels. All results are graphed. So, you can watch your luminance fall off as the lamp ages. We discovered a couple interesting issues in a theater using the LSS. We had the LSS measure the SPL of "silence." We found that it increased one day and stayed that way. A rubber mount had failed in the air conditioner causing low frequency vibration in the auditorium. Another interesting issue was now and then there would be increased high frequency rolloff on the left and right channels for a week or two (but not the center), then it would come back. That turned out to be the speakers were covered by masking when a flat movie was shown.

The LSS, like most of the USL test equipment, is something that this industry would be better off with being in production.

Yes, you can save the brightness setting. Go to lamp, adjust to the required setting, then memory list > entry, as so:

You can then link the lamp setting file you created to a "title" (NEC-ese for macro), as so:

Thanks for the instructions. I was able to save the lamp setting to higher brightness. However I cant use the "title" function. Its grayed out. Need a password and im guessing you cant tell me that to put the DCC app in service mode?

I'm very sorry, but no: we have to sign a NDA when we do the NEC training class, and it's against the rules of this forum.

Thanks Leo! I will do that!
