TigerScent Posted January 6, 2013 Posted January 6, 2013 (edited) I purchased a Panasonic surround system some time ago, without the controller module ie: DVD player etc, and just ended up with the Subwoofer and 5.1 surround speakers. I need to identify the connections on the plug that goes to the subwoofer and main amp, which supplies output to the speakers, .... SO that the output connections of a surround soundcard can interface with the input plug on the Subwoofer/Amp .... (CN501) If someone with knowhow in this area can let me know what the connections are and mean and what to connect them to and what not to (or what is not necassary) that would be super gr8 !! The connector code on the schematic is: CN501, and I need to get the 5.1 speakers connected, as well as the blue led 'on' light and remote switch 'on' and a mute button. If anyone can help it would be much appreciated. I have had this sitting around for about 2 years new and not connected. I need to connect it to my new PC. I have attached the schematic: Thanks....sch1_2.pdf Edited January 6, 2013 by TigerScent
TigerScent Posted January 6, 2013 Author Posted January 6, 2013 (edited) From what I can see on the schematic: (1,25) "AC1" + (3,23) "AC2" must be + voltage; ...while (9,10,13,16,18) "A GND" x 4 must be - voltage. (all are connected) ...yet --- (6) "D GND" is not part of the 'ground connected hub'. (7,22,24) "FL" must be 'front left' (11) "FR" must be 'front right (12) "SL" must be 'surround left' (14) "SR" must be 'surround right" (15) "C" must be 'centre' (17) "SW" must be 'subwoofer' (20) "mute av centre surround sync" appears to be some kind of 'mute surround' feature leaving only stereo? I have no idea what: (2) "DC DET" is for ? (4) "8Y86V" is for? (5) "HP CNT" is for? (6) "D GND" is for? (8) "HELP" is for? (19) "PC CONT" is for?(one must be for the 'on' led light ie: '8Y86V + D-GND?)...if anyone can help would be appreciated... Edited January 6, 2013 by TigerScent
TigerScent Posted January 8, 2013 Author Posted January 8, 2013 ...no-one have any idea? no knowledge of this kind of thing? Surely Zaph would know !! Zaphhhhh - need your expertise.....
TigerScent Posted January 9, 2013 Author Posted January 9, 2013 I didnt think it would be that difficult : Might have to contact Panasonic
TigerScent Posted January 12, 2013 Author Posted January 12, 2013 ...well, its slowly but surely coming together with verfication from other sources..., thankfully ---
TigerScent Posted January 26, 2013 Author Posted January 26, 2013 Well, things are clear to a point --- but still need some assistance/verification: At least that part is out of the way; ie: pins - 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 : a total of 6 + and 5 - connections = 11 pins accounted for.(in another schematic pin 6 is also connected to GND, giving 6+ & 6- = 12)Now, the next questions are:1. What is the pin 22 & 24 that says 'FL' mean? It appears to have something to do with the 'front left' channels (in service manual schematic is 'FL1' for pin 22, and 'FL2' for pin 24 - page 69)2. pin 6 must be ground hub 'D-GND' (in service manual schematic is connected to GND also -page 69)3. What is pin 20 'Mute AV Centre/Surround Sync' for (for stereo FC only?) (in 2nd schematic is labelled 'FREQ_HOP' - page 69)4. What are pins 1 & 25 'AC1' for? (also called 'SUBAC1 & DVDAC1')5. What are pins 3 & 23 'AC2' for? (also called 'SUBAC2 & DVDAC2')6. What is pin 2 'DC DET' for? (DC detection for fan circuit?) ** Posted: Wed Aug 10, 2005 7:33 am Post subject: HT 900quote: -------------------------------------------------------------------------------I am posting again to let you all know of a workaround. The problem here is that the circuit supplying current to the fan on thw subwoofer unit never turns on. As the fan circuit is monitored via the DCDET line, power output is limited in this state, and any attempt to get more power out of the unit trips the DCDET leading to power supply shutdown and F61 code.I managed to get my unit working again by bypassing Q510 in the main subwoofer board from emmitter to collector with a 220 ohm 1/4w resistor. This switches Q508 which supplies current to the fan.This all started because panasonic were concerned about fan noise and dreamed up this circuit to switch the fan on during louder passages of music! Unfortunately many people reported that their fan never came on.Hope this will be of help to others in the same predicament as me. Pity that this good looking and sounding unit had a design flaw. http://forum.eserviceinfo.com/viewtopic.php?p=11785 unquote -----------------------------------------------------------------------------7. Pin 4: 8Y86V or SYS6V appears to be LED light?? (or possibly 'temp detect'??)8. Pin 5: HP CNT also has 'Mute H' label on other schematic (page 69)9. Pin 8 has 'HELP' on one schematic, and 'SUB+B' for same pin on the other (page 69)10. Pin 21: is labelled 'Sync' ??Attached is a service manual: page 69 has another schematic of pin configuration/labels http://diagramas.diagramasde.com/otros/panasonic_sa-ht520e.pdf More is also explained in the following: blkmain.pdf file Going by the schematic: blkmain.pdfDCDET indicates fan controlSYNC seems to be a power switch?PCONT - seems to be involved with DCDET and fan control - how do they interface ?SUBAC1 & SUBAC2 - seems to involve power supply?FL1 & FL2 - seems to also involve power supply?Can anyone confirm? blkmain_1.pdf
TigerScent Posted March 10, 2013 Author Posted March 10, 2013 I think my cat called 'Fiiirrtz' would know more about this LOL
