Author Topic: Dolby analog reader pin-out config Garry Knapp Film Handler Posts: 50 From: Mississauga Ontario Canada Registered: Oct 2016 posted 11-01-2016 03:32 AM                        Working on my Vic5 and looking for any info on the analog reader that came with this one. Seems they vary...this PCB is made by Cinemecannica with a pros D08140. I am primarily concerned with the power pins...  |  IP: Logged Jonathan Wood Expert Film Handler Posts: 206 From: Oxfordshire, United kingdom Registered: Jan 2008 posted 11-01-2016 05:31 PM                     Hi Gary , There were two types of board a horizontal and vertical one , it looks like u have the vertical one but in any case the pin outs are as follows: Signal is Pins 1-6 Pin 1 being the outer one. Pin 1 - L+ Pin 2 - Ground Pin 3 - L- Pin 4 - R+ Pin 5 - Ground Pin 6 - R- Supply Rail is Pins 1 -3, Pin 3 being the outer one. Pin 1 - +ve anything between 12 and 24 volts. Draws around 100mA. Pin 2 - No connection. Pin 3 - -ve do not ground. Be careful not to reverse the DC or you will destroy the board! . I used the above to wire my board up and it all works fine. Good luck.

Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 11-02-2016 06:25 AM                     Um...no. Kinoton used their own LED driver board to power the preamp module. Kinoton had three different varieties of LED driver boards (one that was completely independent and needed its own AC supply of 120 or 230V) and two that used the 24V within the projector to generate what it needed for both preamps and the LEDs. I haven't met one Kinoton projector that was new from the factory or even a retrofit that didn't have the preamp powered from the its own board with a factory provided cable. Perhaps you are thinking of the digital SR*D board? All of those were driven from their respective SR*D processors.  |  IP: Logged Sam D.

It was an impractical idea in any case, but it saved a few $$.  |  IP: Logged Garry Knapp Film Handler Posts: 50 From: Mississauga Ontario Canada Registered: Oct 2016 posted 12-12-2016 05:16 AM                        its working! I managed to get music thru (via non-sync) and audio off the film. Music plays fine but the soundtrack is missing one channel. Hopefully its not a difficult fix... thanks guys  |  IP: Logged Jonathan Wood Expert Film Handler Posts: 206 From: Oxfordshire, United kingdom Registered: Jan 2008 posted 12-14-2016 10:09 AM                     Hi Gary, which channel is missing? Glad you've got it working .  |  IP: Logged Garry Knapp Film Handler Posts: 50 From: Mississauga Ontario Canada Registered: Oct 2016 posted 12-15-2016 05:01 PM                        the right is sort-of missing. i can hear a tiny bit there and its crackly.  |  IP: Logged Garry Knapp Film Handler Posts: 50 From: Mississauga Ontario Canada Registered: Oct 2016 posted 12-19-2016 04:17 AM                        update: RH side is better after playing around with the lateral adj on the reader. still a bit crackly, but it seems to improve the more it gets used.  |  IP: Logged
