Has anyone here heard about the release of the CP650? I had seen it mentioned in one off the pamphlets from Dolby, but didn't think twice about it. Now a friend of mine says they are ready for release. Any news or pics? I'm sure this is EX ready. Any help is appreciated!

Raj:

I can't recall any announcement, and I can't find anything in a quick search of the Dolby web site. What did you hear about the features of the new processor?

I think a few Dolby folks "lurk" here, maybe one of them will provide details, if they are available.

You two boys better hide...they might already be sending people to come and get you. Think of the CP650 in "Roswell" terms for now. At least any important details that we'd all like to know about anyways.

Dolby is finished with the CP650, but they are going back in to add bugs and glitches to make us all nostalgiac for the CP500

Actually, I know very little about the CP650. I just hope that it doesn't have a STUPID MENU SYSTEM like the CP500 does. I hate going through what seems like 20 very slow-changing screens just to adjust dolbytone. Also, the format switching on the CP500 seems slow to me, I hope they fix that.

Also, on the CP500 you must cue SK8 which must be set up as Dolby Digital to cue the SA-10 into EX mode. But I run those cues right after the policy trailer before the digital comes on, and it gives me a "Not Ready" and never goes into EX. I must change the auto digital targeting for every EX movie to avoid this. I like how the CP65 will try to go to digital, but instantly fall back to SR. When digital is restored, the EX will come on.

I do like the serial control capabilities of the CP500, so hopefully they retain that (I think that is the plan).

The CP-650 is reported to have room for the EX boards but it will not normally include the them with it. It will have less functions than the 500 but with the addition of some additional new ones. I was not told specifically what though. Hello Lonnie.......Are you out there lurking???

Well I doubt this is where Dolby is heading with their design, but here's my two cents.

Please lose the digital equalization. Nothing beats the good ol' cat64 cards for great sound.

Also, let's get that external digital input configured directly for a DTS input. No more of this "pull these two pins for the subwoofer to work" nonsense. And where's the SDDS input? I'd like to be able to leave the SDDS eq FLAT and perform the equalization within the Dolby processor. This nonsense of the SDDS "taking over" the audio system is a joke. The CP650 NEEDS two completely separate digital inputs, although I would personally like to see three.

While I'm talking about external inputs, the dual non-sync was a fantastic idea. Please leave that.

Can we please get back to tweekers? I agree with Joe that going through a maze of menus is just plain annoying. It's not that it's hard or anything (I've learned how many times to hit what button and in what order, so the CP500 is always seriously lagging behind my commands), but what is the benefit other than being able to store the settings on a disk? Is it a cost issue?

Anyone given any thought to 1/3 octave eqing on the surround channels?

How about 70mm? The last good 70mm machine Dolby put out was the CP200.

The front panel needs more than 8 soft keys. I think 12 should suffice.

Brad,
1/3 EQ's yes yes yes!

Ive noticed that the overall surround response using only full ocatves is very "peaky" for lack of a better term. The overall response is not a smooth curve like the screen channels but instead is one that looks like a NASDAQ stock profile. Although surrounds are for special effects, echoes, and other not so discrete type sounds one can argue that it would be more of a waste to include 1/3 ocatave eq or possibly argue that it is simply not needed. I say if SDDS and Panastereo do it...well then Dolby should as well. Ive always been a bigger fan of parametric EQ's over graphic EQ's and so if dolby insists on using ocatve EQ's for the surrounds with the CP650 then they should just go for parametric EQ's and leave it at that. The new QSC DCM is a perfect example of parmetric EQ usage. What do you think Brad?

From the info in the latest BKSTS is as follows
EX standard in the box
1/3 octave Digital EQ on all channels
SR and A type NR in the digital domain (not good)
laptop interface (finally)
No 70mm capability (bring on the PanaStereo)

I have heard a rumor that Dolby is testing one of these units in Dublin at the new Regal 20.

Joe: and to anyone else that is interested. Dolby has a new version of software for the 500 it is 1.61. It is suppose to change to EX or SK8 when it sees EX. I ran into that doing a service in the small town of Willows. I could not tell if it was working right because MI2 was on that screen, but the boot up window says it was EX. I have not talked to Norm or Lonnie since then, but they should have it.

By the way I hear that Dolby has a tech page similar to the DTS tech page. Does anyone know where to sign up for it?

Kevin: I am using software version 1.61EX. There is no auto EX detection. I asked Russell Allen from Dolby (Hi Russ, sorry if I spelled your name wrong) if they were working on any auto EX detection and he said "no". I asked him this on the very same day he personally installed 1.61 into my CP500's (and 1.61EX into my EX house that has an SA-10 and a CP500).

The only difference between 1.61 and 1.61EX is that 1.61EX kills the EQ on the surrounds in the CP500 so they can be adjusted on the SA-10

DTS has had auto ES detection from the beginning. DTS kicks ass.

I'm scratching my head here trying to figure out how an EX-auto-detection circuit would work. Any ideas? Conceivably, any film with split surrounds would have "decode-able" information that could be played through the center-surround channel, even though it may not have been intended to be reproduced in that way.

I think the EX-auto-detection circuit works by a bit in the AC3 data. That is, you would have to have Dolby Digital in your theater. A signal comming out of the DA20 would set the EX feature in the processor. I can't see any way a "analog-only" installation would be able to detect it.

By the way, does anyone remember the plugs on the back of a CP200 labeled, "TONE DECODE?" The signals (on the pins) went to the optical preamp. What were they for? I thought they might be an idea that Dolby was thinking about (but never implemented) where the format (01, 04, etc.) would be auto-slected. On our preamp pc board, the copper traces that connected those signals were cut, probably to reduce noise.

Yes the CP-650 is official! According to Dolby document S00/13164:

"The CP650 represents Dolby Laboratories' latest generation of cinema processors. With a completely new design, it incorporates the latest technology for decoding digital and analog Dolby optical soundtracks. The processor fits in a 3-U rackspace (5-1/4" high).

All processing occurs in the digital domain. SR and A-Type noise reduction are achieved digitally, as is third-octave equalization for all playback channels. A digital parametric equalizer is also included for the LFE channel.

Setup and alignment can be accomplished via a dual-trace scope or Windows-based PC. All alignment connections and test points are available at the front panel of the unit to simplify setup and testing.

The CP650 has digital inputs for two projectors" <Yippie!> "supporting the Cat. No. 701 Dolby Digital reader, a six-channel analog input for external digital processors, two pairs of nonsync input connectors (RCA Style), a microphone input (balanced XLR connector) for P.A. use and B-Chain alignment, stereo PCM audio capability, and Dolby Digital for consumer applications (DVD and HDTV).

There are balanced outputs" <finally> "for eight auditorium channels: left, center, right, left surround, right surround, back left surround, back right surround, and a subwoofer output. The unit features a hearing-impaired output, and an Ethernet port to accommodate future control and monitor functions."

It apparently comes in two flavors:

CP650: 35mm Dolby Digital Surround EX and Dolby Analog soundtracks.. $11,500.00 List.

CP650-D: For 35 mm Dolby Digital and Dolby analog soundtracks....$10,500.00 List.

The CP650-D can be upgraded with a UEX/650.

Yep.... There's a full-page colour ad for the 650 in the latest edition of Cinema Technology Magazine, available from the BKSTS. Kinda looks like a Sony PlayStation probably will someday.
