So I was given a surround sound entertainment console...
« on: November 16, 2015, 12:57:55 am »
I do some computer work for some people in my locality, free of charge because really, I'm not vetted and I have nothing better to do. One of the people I worked with gave me a Panasonic something-or-other that requires use of a DVD player to hook up other equipment.

It's rather nice, with a beefy, pre-noughties desktop-sized subwoofer, four small speakers for left and right, front and back, and a big one for centre. They feel and look like quality, but then there's how that audio is received by the sub; A 25-pin connector. DB25 you say? Nah, none of that standardized rubbish! Panasonic uses their own proprietary 25-pin connector to pair together the woofer with a DVD player. Then you hook up other equipment to the DVD player. Looks nice and all, but I want to hook this thing up to my television via an S/PDIF optical cable!

Seems like that's kind of a toss. So now I am curious; How could I cheaply and easily fab and secure wires to the port the woofer uses for line in? There's a top row of 15 pins, a bottom row of 13 pins, with a clip in the middle to secure the port onto the woofer and player.

Since some of you are awesome enough to have fabbing equipment, if somebody could sacrifice one of these cables to salvage the connector, a 3D-printed plastic enclosure can be made to hold together the port and two RCA connectors for audio. (Even though it is a 5.1 surround, it still uses only left and right channel for audio. Hmmm...) I'll pay whatever is fair if somebody wants to go the extra mile and make a couple small adapter to standardize these ports with RCA connectors.

For reference, the cable's model number is K1HA25HA0001.

Quick edit; If there is an amp I can use with the ha-ha cable instead of the DVD player I was given to go with it, then I'd be in the clear for the most part and not need to worry about a cable or board to convert it.

Further edit: yeah I know the amp is in the DVD player but I only need the amp; I have enough DVD players in my house in the form of computer optical drives!

Pictures...?

It might not be really proprietary, but just am odd Japanese connector.

What? It's not "offtopic" in any sense.

If you look carefully at the connector for any . Panasonic is not a connector manufacturer, they'll probably use some other Japanese company's connectors - JAE, JST, DDK, Tajimi, and Hirose come to mind... the latter might be worth investigating.

if it's the right pitch, a row of pin headers might work and a lot cheaper than trying to trace an obscure part you will only want in single quantities.

failing that you could just open the case and break out the connections you want off the pcb
