Re[3]: JVC service or questions

Sorry, I used my incorrect mail ID.

How can I get schematics/service manual for JVC subwoofer Model # SP-PWM505. This is part of TH-M505 home theater system, but I do not know if it has a separate manual.

I am also trying to find out if the 9 pin DIN is a digital data link or analog
input to the amplifier..

Any help, much appreciated.

Thanks a bunch

  Hello Peevi
  
  JVC doesnt seem to actually do a manual for that model now, as they dont even have an operating instructions one either.
  
  The connection to the speaker will be analogue, however what is wrong that you require the sevice information?
  
  I only ask out of curiosity as l am an engineer, although not conected to JVC as such.

    John, Thank you for a response. Actually, there is nothing wrong. I bought it by itself, thinking I would be able to use as a sub. After seeing its input I thought I could hook up a RCA socket and still make it work like a standalone powered sub woofer. Do you happen to know the pin out for the 9 pin DIN connector? Thanks Peevi

      Peevi I also picked up a JVC PWM303 powered sub for a THM303 system. Mine has an 8 pin mini din. Any luck finding the pinouts for yours. If as John says they are analog it should be easy to hookup a cable to the connector. I am going to risk taking mine apart and see what there is inside. It seems to me that the THM303 receiver had 700 watts of power which would lead me to beleive that the satelite speakers (front, rear and centre) would be powered by the receiver. Any thoughts you have would be helpful.
