I'm wondering if you guys have some ideas as to what is happening to some of my houses. On two of the houses, the SRD/DTS is not working and the analog sounds very soft. It is very difficult to hear any sound unless the volume knob is turned almost all the way up. Unfortunately, when I do this, the sound is distorted a little--but if I do not, then there is hardly any sounds at all. Once the feature is over and the processor kicks back into non-sync the music is blaring again since the volume is all the way up. Also, on a couple projectors the digital is not automatically kicking in even though DTS recognizes the timecode and the SRD is registering the soundtrack. I have to manually put it in digital otherwise it stays in SR. Finally, I have one house running in "bypass." I have tested the channels and they all register on my meter, yet when the sound is processed through the Dolby unit, it is either lagged, slurred, or extremely low. Any help would be great.

All the optics have been thoroughly cleaned. I cannot figure out the problem.
 

You might also need Dolby's pulse extender for that CP65 to recognize the automation pulses. I am assuming you are using the dts automation board?

On your analog, it sounds like you need a tech to perform an A-chain.
 

Do you have any green Dolby test film? Run a loop of that and look at the preamp. You should have two sets of green lights.

If not you'll need somebody to come out and give your A-Chain a good going over.

I have one theatre that'll call me up every once in a while and they'll just tell me, "We can't get Dolby Tone in number 'n'. Can you come out and do an A-Chain?"
When I see their number come up on the phone I say to myself, "Oh Sh**!", because when they call I know they really NEED it!
 

When running DTS with DD/CP65, please power down the DA20 when running in DTS. And, when running in DD, please power down the DTS. You need to do this for DTS to DD/CP65 only. The problem is that the logic pluses from both units "butt heads' and the CP65 will not switch correctly.

If the audio has a problem when running in digital (DTS and DD), then you need a service call on your CP65.

Thank you for the advice, I will check it out this evening. As for getting the tech in... it seem next to impossible. For example, one would assume that a downed house would have the tech running to the doorstep--well, almost. One of the lamphouses blew the rectifier due to a loose connection somewhere. One of the operators tried his home phone, cell phone, and pager that very evening to get him in to fix it right away (theatre was running a print of Pearl Harbor). No luck that night but the next morning he figured he would have better luck--alas, no luck whatsoever. It took a call to the GM then the DM then finally the tech's boss until we received a call from the technician himself. He came out and fixed the downed house but neglected to repair the now two houses that are in need of audio repair. I cannot do the work needed on them because I haven't got a clue on what I would be doing to physically repair the unit. As for A-Chain or B-Chain... well, you got me. Thanks for the words though.. I appreciate it.

Just last week I was arriving home from one place and I got a call from another. Place "A" was already half way between home and Place "B". If they had called just 2 hours earlier I would have been able to make it there in 3 hours or so. But NOOOOO.... they had to wait until I got all the way home!

Anybody who is worth his salt should at least be available to take your call during normal theatre hours. An e-mail address is a good backup.
