Author Topic: Dolby CP500 Output connection Steve R Pike Film Handler Posts: 66 From: Gloucestershire, UK Registered: Apr 2011 posted 06-22-2019 05:39 PM                     Hi. I posted earlier about acquiring our old 35mm system for my home cinema. I've just purchased a Dolby cp500 from eBay and having a look at the output connection to amp/speakers. Having never actually installed any equipment, can any one advise what I need to use to connect the cp500 to an amp/speakers. I see that it says to use a pheonix connector but I'm sorry to say that I don't know what that is! And how it can connect to the speakers. I realise that this question may sound silly, but having never seen or used a cp500 setup I'm just struggling to work it out! Any help or info is greatfully received.

It is a green plastic strip and there are hole/clamps for each wire with a small screw to close the clamp. You will need a small strait blade screw driver to open/close the wire clamp. While you do not have to it works best if the wires are tined.

While it may make them easier to insert it will interfere with the bond created by the connector. https://www.eptac.com/ask/when-to-tin-and-not-tin-wires/  |  IP: Logged Steve R Pike Film Handler Posts: 66 From: Gloucestershire, UK Registered: Apr 2011 posted 06-23-2019 04:32 AM                     Thanks both for your replies. Ordered a couple of connectors so they should be here this week. Sorry, one final question - am I right in thinking that the wires coming out of the processor are connected to an input on an amp and then out to the various speakers? For the home cinema setup I was thinking of using a Denon receiver amp (something like Denon AVR-X250BT) or do you have a suggestion for something else? Apologies for the questions - i can show a 35mm film with my eyes closed but I've never setup the equipment that goes with it  |  IP: Logged Don Furr Jedi Master Film Handler Posts: 509 From: Sun City, Ca USA Registered: Nov 2002 posted 06-23-2019 09:19 AM                     Page 138 of the CP500 manual begins describing the connections you need to use in your project. http://www.film-tech.com/warehouse/manuals/DOLBYCP500.pdf  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 06-23-2019 09:54 AM                     It appears that this Denon AV receiver only offers stereo analog inputs: https://assets.denon.com/assets/images/productimages/AVRX250BT/AVR-X250BT_slider5_eu.png - Carsten  |  IP: Logged Steve R Pike Film Handler Posts: 66 From: Gloucestershire, UK Registered: Apr 2011 posted 06-23-2019 10:40 AM                     Thanks both ... Any suggestions on a suitable AV receiver and what to use to connect the outputs of the cp500 to the AV receiver (RCA?)? I was hoping to use the same AV receiver for the video projector I am going to use for Bluray presentation.

Which you then simply plug into your AV receiver/ home cinema amp. You just need to make sure the amp has separate analogue inputs for L/C/R etc . The other issue you need to be aware of with CP500 is whether or not it’s configured to run in bi amp mode , if it is it will sound awful when you play it through your home cinema amp. It can be set to non bi amp very easily by moving a jumper on the main board, sorry I can’t remem the exact procedure but it’s in the manual.

I've got some of the connectors on their way in the post and found an amp that can take multi channel RCA (Denon AVR 1908) but need to wait until payday to buy it! Hopefully the processor works fine, but will bear that in mind about the bi-amp if the sound is awful.

While it may make them easier to insert it will interfere with the bond created by the connector. I was just about to say that IPC standards forbid tinning of wires in threaded or clamp fasteners: 1) The connection isn't as sound because the fastener can't "bite" into the wire as well. 2) The wire is more likely to break off. 3) Tinning wires, unnecessarily, can encourage the growth of dendrites in some circumstances. (AKA: "tin whiskers.")  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 06-24-2019 10:32 PM                     I always use ferrules on wires for a terminal  |  IP: Logged Gary A. Hoselton Film Handler Posts: 59 From: Portland OR U.S.A. Registered: Nov 2005 posted 06-25-2019 12:13 AM                     In the early 1980’s a congressional committee was touring a kidney dialysis center in Washington DC and, with press cameras rolling, an artificial kidney machine commenced emitting smoke and flames. It was an older machine, and stranded wire to the power switch had been tinned and wrapped around each screw. Over some years the tinned area relaxed, the connections commenced arcing, stuff overheated, and we, the manufacturer, suffered the embarrassment of the demise of our product being seen on dinner-time TV news in the nation’s capitol. We initiated a voluntary recall and quickly corrected those of that model still in use, and received no penalties. Regarding your new CP500, power it up and see that the display is working OK, no black areas large enough that you can't read some of it. Otherwise, a fine sound processor. You may need a software update downloaded, to latest version.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 06-25-2019 07:37 AM                     quote: Gordon McLeod I always use ferrules on wires for a terminal Depends on a whole lot of factors. I usually like using ferrules for stranded wire, but I often find them to be crimped badly or they choose the incorrect size, where they slide right off the wire... Some of those clamp-style connectors nowadays also don't work right with ferrules, because they can't really get a grip on the ferrule.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-25-2019 11:05 AM                     What Sean said!
