Next step was to wire the bulb up as nearly all Dolby Stereo CP200 that I have seen in the past years at the local ABC 1, Bournemouth, (London) Odeon Leicester Square, Odeon west end, Warner west end, and Empire Leicester Square Empire 1, near all never had an illuminated VU meter so I thought I do it with mine.

Thou I fitted soldered reisotor to the bulbs a surge peak when switching it On must have blown the bulbs, no matter I have some white LED that I will eventually install, when not feeling depressed as not having my Cat, Sooty around anymore has left a huge deep wound, thou I may have new Cat Bear, and my other adopted Cat, Magic, I still find each most days now extremely difficult.

Yes over the short time the bulbs have slowly blown and ones in most CR radios I have have lasted 40 years or more. I think I should have fitted a higher resistor first time around and thou I never actually checked with the multi-meter what voltage reading if it was 12v that is far too high and should have been at least 6v or 5v. I not sure if any bulbs are still working.

Sooty appears in the video and has a scratch at the carpet tiles.

Is there some advantage to using a commercial cinema processor at home?

Or is it just for fun?

Cool setup. Those displays make the RME look big, until I realized they aren't the standard 7" "official" units. What hardware are you using?
Hyperpixel 4" touchscreens in two of these cases:


Two strong magnets in the bottom of each case holds them VERY securely to the RME.



If you want to use a Pi 4, this case should work with the Hyperpixel 4" touchscreen.
