Anyone having sound issues with Gran Tarino? I've ingested it in three different auditoriums and about to try it on a fourth and all of them right when it says "directed by" at the begining of the credits I start getting popping in the speakers like someone is taking a jack and unplugging and plugging it in rapidly with amps turned to 10000. In other words its a pretty loud pop. rice crispies on steriods.

It must be on the hard-drive you received that way. Can you get another? If it was a common problem I'm sure we'd have heard all about it by now.

Further, I can't assist sorry, we're only playing it on 35mm.

Not with 'Gran Torino' but we had a problem with random noise blasts that turned out to be the digital input card in the CP650.We got new drives and even replaced the server before we tracked it down by replacing everything.We could never "make' it happen, never seemed to be at the same spot.
No idea why it happens to you at the credits.Any chance the automation could be causing noise if you bring up lights when the credits start?

Time to get your service tech busy! Could also be blown drivers. Have seen alot of them with deteriorating foam surround on the woofers (E-V)... Digital Cinema's dynamic rang can be hard on older drivers.

But it's only in the credits...and Gran Torino doesn't exactly pump in them during Clint's song.

Have you had anything upgraded in the automation recently or changed anything in the programming?...New dimmers maybe?

My first thought after reading this is try cycling your dimmer through its presets during playback (or even with no sound playing but set on your normal playback input) - maybe the mid setting is causing noise for some reason.

Also - what server/sound processor combination do you have? (some of the Cinedigm installs with DTS-6ADs got the wrong analog audio cable installed)

A phase control dimmer would normally cause hum not popping sounds
It could be relay closure noise from automation dry contacts

- NA10 and Lutron graphic eye system. Are the automation and dimmers. I don’t believe its that because the sound starts about 1-2 minutes after the light cue.

- New speakers all the way around. New building. We just opened 4 months ago.

- TI upgrade, Dolby show player, store, library, upgraded software to latest versions on all.
- No new dimmers installed recently.
The popping sounds exactly how it would sound when you are unplugging a microphone or guitar into an amp full blast. That thud of bass..etc etc.
It has recently gone away yet again with new content and re-ingested old content. Technicolors replacement drive worked for Gran Tarino.
