Author Topic: recommended Blu-Ray players Sam King Expert Film Handler Posts: 120 From: Los Angeles, CA Registered: Oct 2006 posted 04-24-2011 05:30 PM                     I am thinking this cable (http://www.infinitecables.com/pop-usa/av_s6-25-rca.htm) hooked to the 650's external 6 channel or the DMA8+'s external processor input should work. I would most likely need to Y-cable the RS and RBS to one RS and well as LBS and LS to one LS, as, and PLEASE correct me if I'm wrong, I cannot get external EIGHT channel analog audio into the 650.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 04-26-2011 09:37 AM                     Yes, if the wiring on the DB25 is compatible with the standard Dolby wiring, this cable should work. You should definitly use the S550 7.1/5.1 analog outputs. The Sony has it's own multichannel setup option with delay and level configuration. You can easily make your own cable from 2-3 sets of stereo RCA cables and a D-25 connector - the wiring is shown in the CP650 installation manual, it's the same for all Dolby processors with this 6ch external in connector. I use a set of transformers (3 stereo DI boxes), then enter the Dolby processor, without adding any hum/noise issues. You might need transformers or not, depending on your devices and installation. You might get away with a digital S/P-DIF or stereo connection for a festival, but you never know which sound formats have been encoded before you finally get the discs. And then it maybe too late. The 5.1 analog output from the Sony to the CP650 gives you peace of mind for all possible formats - from mono over stereo and Dolby AC3/dts up to all current BluRay formats. - Carsten  |  IP: Logged Bajsic Bojan Expert Film Handler Posts: 190 From: Ljubljana, Si, Eu Registered: Aug 2008 posted 04-26-2011 01:38 PM                     @carsten: which isolator/di box do you use to convert unbalanced? or do you get balanced out of the DI and just use one leg of the signal? i'm currently using an ART t8 8channel isolator/transformer with varying success, but i really miss a ground loop switch  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 04-27-2011 08:29 AM                     As neither the Sony nor the Dolby has balanced inputs, I use the transformers only for ground isolation. I have very simple stereo transformers, probably not easy to find outside germany, but any passive DI-Box with ground lift or custom cabling should do. It really helps with 6 additional analog channels from a consumer device. I would even suggest to put something like this in front of the EX-6ch analog In as a general measure. There should be 8ch 19" units available with ground lift. This one is 6ch, and even has level adjustment, but I don't know wether it's available outside germany: http://www.thomann.de/de/millenium_adi6_di-box.htm They do ship internationally, though. The Sony has slightly lower levels, especially after surround level calibration. It's still fine for our CP65, we just have to dial up to Dolby level 8-9 or so. But if the DI box offers some gain itself... With the Sony 7.1 output and a suitable speaker/amp layout, maybe an 8ch device would be a better choice. - Carsten  |  IP: Logged Sam King Expert Film Handler Posts: 120 From: Los Angeles, CA Registered: Oct 2006 posted 05-06-2011 12:32 AM                     So I got the cable in, hooked it up to external 6-channel on the DMA8+ and only got humming. ???  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 05-06-2011 04:59 PM                     Are you able to check proper wiring of this cable? Did you connect the BluRay Player yet? Have you verified it is actually using the discrete analog audio outputs? Have you checked any other source into the DMA8+, e.g. iPod? - Carsten  |  IP: Logged Sam King Expert Film Handler Posts: 120 From: Los Angeles, CA Registered: Oct 2006 posted 05-15-2011 10:44 PM                     Tried with my iPod, out of the 6 RCA connections; 1 went to RIGHT, 1 went to LEFT, 1 went to ALL SURROUNDS, and the other 3 went no where. I am so confused...  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 05-16-2011 08:59 AM                     You should check the wiring of this cable with a multimeter (or have someone check it). This is the reason I rarely buy 'non-standard' cables, but always choose to make them myself. The right pinning can be found in the Dolby manual. It's more or less the same for all Dolby processors with DB25 analog connections. The DMA8 will need to be in film or pass-through mode to output the external analog channels. You should also make sure your BluRay Player's audio setup is correct. - Carsten  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 10-26-2011 12:15 PM                        Bump. The Sony BDP-S280 is just "OK." It has compmenent output, a counter on the front panel, and the on-screen display can be disabled. On the other hand, it goes into sleep mode if left in pause or stop for more than a few minutes (and this seems to not be able to be disabled). It is a current (or recently-discontinued) model that is readily available online.  |  IP: Logged Callonnec Laurent Film Handler Posts: 3 From: SAINT DENIS / FRANCE Registered: Mar 2011 posted 10-27-2011 09:36 AM                        Hi, i was working on a similar idea (DB25 to RCA Snake) and i found than some of this cables are for Tascam audio link, so the PIN OUT RCA diagrams won't work (i find a diagram here SNAKE DB25 RCA DIAGRAM. I hope the one you get doesn't fall in this category.  |  IP: Logged William F Green Film Handler Posts: 84 From: Brighton, East Sussex, UK Registered: Jun 2005 posted 10-28-2011 11:31 AM                     Carsten - you mentioned an upgrade board for the DP90 to make it HDCP compliant. Does anybody know if there is an upgrade available for NEC NC800 to make the DVI inputs HDCP compliant? Otherwise we will be looking at an HD Fury to input to the proj. via the Cine IPM I guess. With our LCD proj. we use a Sony BDP S360 which works well - it can be paused literally all day (except on Universal's BD's!)and can be set to not show on-screen messages at all. One useful setting with this Sony is that RGB output levels on HDMI can be set to 0-255 rather than the standard setting and with our LCD projector this is vital as the auto setting gives grey-ish blacks whereas the 0-255 setting gives dark blacks (as dark as the proj is capable of). Would buy more of these if they were not discontinued. Recently bought a Panasonic BDT 110 which I'm not so keen on at this at all. Can't adjust the RGB levels on HDMI so pic looks washed-out on LCD proj. On-screen displays can be set to 'off', BUT unfortunately after 30mins on pause it goes into 'power saver' mode (or something similar) and then proudly displays this fact on-screen when it's 'woken-up' again! Will not be buying any more of these.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 11-01-2011 08:47 PM                     William - you're still on stereo, so I guess a lot of players should basically work for you. I remember that some Philips players allow to set the position of subtitling - could be an interesting feature as well if you do screen DVDs/BDs with subtitling. Most current Sony players should have more or less the same feature set, so I guess you should be fine with other Sonys as well. Only that Sony doesn't offer affordable devices with multichannel analog outputs anymore. You should be able to still get S360. We have an S550 (7.1 discrete audio output) and I would buy it second hand if needed. A lot of these machines are now exchanged for 3D players and should be still in good condition. If you do commercial screenings, a second player is certainly a good investment. - Carsten  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 11-02-2011 11:14 AM                     The CP650 can do 7.1 but only with digital inputs (4xAES) which requires an (expensive) option card. There is no 8 channel analog input.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 11-02-2011 01:53 PM                        Why do a lot of DVD/BR players refuse to stay in Pause mode? It's not hurting anything. I submit this is a holdover from VHS days where if you would leave it in pause for too long, it would damage the tape. Or else it's a holdover from the days when "burn-in" was an issue on TVs.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 11-02-2011 08:18 PM                     Some plasmas and even LCDs are still somewhat prone to burn-in issues, so, a screensaver does make sense. You just need to find a player which can have it deactivated. I suggest downloading the manual, which is possible for every manufacturer, and read the part describing the setup options. There are, however, some BDs around with their own screensaver which usually can not be deactivated. I suggest to buy a HDMI switcher/splitter and 24p capable control monitor/TV along with the BluRay Player so one can start the disc and proceed to the main feature without the audience seeing it. - Carsten  |  IP: Logged
