Convert DIN-9pin (6channel) to 3xTRS 3.5mm | Noob help!
 
I'm not sure where I should have posted this, im a noob with this kind of thing. I would greatly appreciate any help, suggestions, ideas or being pointed in the right direction!

I was given a Sanyo DWM-3500, an older 5.1 surround sound system with a powered sub and a main unit. (I know its not good, but its better than what I have and right now I cant spend money.) I would like to connect my computer to it. The problem is that I am missing the main unit which the sub connects to via a DIN-9pin. Im not sure if its proprietary or if it follows a template/standard, but I want to connect it to 3x TRS 3.5 mm outputs from my computer. How can I determine what each of the pins in the DIN-9 are for, and then how can use that information to figure out how to convert the the 6 channels being output from my computer and what the other 3 are for (just guessing thats how it will work).

My computer's output:

Specs:
Powered Subwoofer (ASX-3500)
Continuous minimum sine wave RMS power output
into 6 ohms at 70 Hz with no more than 10 % total harmonic
distortion (with the other amplifiers off) ................. 75 Watts
Satellite Speakers (Front Left & Right, Center, Surround Left & Right)
Continuous minimum sine wave RMS power output per
channel into 8 ohms at 1 kHz with no more than 10 %
total harmonic distortion (with the other amplifiers off)
.................................................. .................................25 Watts
AUDIO INPUT (6-CHANNEL):
DIN 9-pin
SPEAKERS (Output):
FRONT (L/R): 8 Ω
CENTER: 8 Ω
SURROUND (L/R): 8 Ω
Power requirements:
AC 120V, 60 Hz
Power consumption:
150 Watts
Unit used:
6.5" (16 cm) diameter, Cone type

Satellite Speaker
Front left, Front right, Center, Surround left, and Surround right speakers
(SX-TS3000S, magnetic shield)
Unit used:
3.1" (8 cm) diameter, Cone type, Full range
Maximum music power handling capacity:
50 Watts
Nominal impedance:
8 Ω

I dont want to replace the main unit, I want to bypass it. Sanyo customer support is HORRIBLE too . I would greatly appreciate any / all help! Im pretty handy and I follow directions well too.

Does anyone have any suggestions or ideas on what I can do at all?

Open the sub and follow the conductors. Post pics here eventually.

Here is a gallery of the pictures I took..

I couldnt get the camera to focus so I recreated the PCB board in photoshop..

Solder on the back of the board six pairs of wires (one signal+ground for each channel) to six RCA female jacks (three pairs). Drill holes for the jacks in the back of the case. One pair will be: Front Left - Front Right, the second S/L - S/R, the third Sub - Center. The 9 pin connector remains disconnected.
The two dots that you left unmarked are the "Mute/Stand By" - probably if you short them you will mute the amp.

Or if you don't plan to use the 9 pin DIN connector ever, just cut the small white connectors and solder them on the female RCA.
From your computer you have the standard 3.5mm stereo jack- red/white RCA cable - three of them. The "surround back" channels (jack) will not be used.

Thank you so much! I had thought of that, but I had no idea if that would work or if it would mess something up. I plan on never using the DIN connector again, so I will solder the wires directly to the RCA ports. I will look up a tutorial on how to do that since im not familiar with it, ive always been a software guy :P If you happen to know of one lemme know! Once again, thank you!

Were you successful in accomplishing this? I've been trying to do the same thing.

fix sanyo axs-3000 powered sub
 
I took my axs-3000 powered subwoofer to a sound repair shop. Ifound out that the 9-pin cable also has a two pin power supply to turn on the sub in normel operation. I want a pinout on the cable to be able to use a computer to drive this system. I want to make a cable and use three 3.5 mm plugs on a 5.1 sound card on a computer.

I recently was given the sub woofer part of this system but I simply want to use it as a powered sub for my existing system (sony str-dh750). How do I eliminate the 9 pin din all together so that I can simply plug in the sub woofer out connection from my receiver to the sub? I know this is a old thread but I really could use the help especially since I cant see any of the photos previously posted.

Find docs for the amp chip, figure out which pin is the input. Making it turn on will be the tricky part. Might be easier to just use an old stereo receiver as an amp. They don't take up much room if you put them on end on the floor.
