I'm in NO WAY an audio geek. I have almost no knowledge what so ever in this field. I'm an electrician and I also like working with computers, inside and out.

At work someone told me they found a speaker in a house that had been auctioned away, and it was to be thrown out. I looked at it, and it was the subwoofer/amplifier from the Z5500 system, and it looked to good to be trashed.

I took it home, and thought it might be usable, but no. There was no control pod.
Then after some googleing i find you guys!

Now. What to do. My plan was making this into an active subwoofer, that would work together with my Sony 5.1 amp. It's got a preamp phono jack out, for subwoofer connection.
One of you had reverse engineered the pinouts, so it made the job quite easy.

I'm an electrician, so I have testing tools. I started measuring from pins on the connector on the back, to the circuit board inside, and found out where pin 6, 7, 8 and 13 ended up. Then I soldered 4 wires on. I mounted an RCA connector in the back of the subwoofer amp plate, and soldered the 4 wires to ground. The I found out that pin 2, Sub In, was the grey wire in the wire bundle, so I cut that and wired it to the center of the mounted RCA connector.

And it worked! My Sony amp can turn up and down the volume on the subwoofer individually.

Now I'm thinking about modding even more. I'm trying to find out, how I could alter the frequency range. The woofer is playing to much of the sound spectre.(Yes, that probably not how you say it)
Great work dude !
I had to copy your tweak on mine. For a while it works but now i got no sound after a quick but loosing "buzz". Did you success for frequency range ?

Yes that is what I currently have configured(the power to pin 8). AS far as the pots you should be able to find some that have dual wipers and configure it with one pot per set. I have found by putting the POTS on I was able to have much better volume control from the PC and not be blasted away at 5% volume.

I was going to do the hack for the RCA version, after my POD died out of warranty (it's at least 4 years since it went out), mapped out the cables and made a schema opened the POD. But first i contacted Logitech (wow i am shocked) after two emails they decided to send me a new replacment pod for free even after the warranty went out!

I read alot about Logitech support being usless, but it's a long time since i recived such great and fast support from a company.

Just wanted to say that you guys who has a broken POD should try support first, if you hack it just to use it as a subwoofer it doesnt matter anyways

hack away!

Thumbs up Logitech support

I was also going to hack my Z-5500 until I (luckily) read "HorusIX" post about contacting Logitech support. I didn't even consider that that was an option for me because of my system being over 2 years old and out of warrenty.

I contacted the english support yesterday and the said that they would be happy to send me a new pod even tho my z5500 was out of warrenty!
WOW! I did not expect that!

Thumbs up for Logitech support!!!

Is there a pin out of the DB15 cable for Pre R636 systems? I have an R540 system with a dead control pod and was hoping to go headless to an A/V receiver.

Thanks,

Question POD R108 to R514 system mod?

I recieved a new replacement pod from Logitech last week to my Z-5500 system, BUT they sent me a POD with a PID version that didnt work with my system.
My original POD i version R514. I guess I need a POD with PID# from R200 to R636??
( According to this cable it seems that way: Logitech Z-5500 (pre 636 PIDs) 3 jack Control Pod Bypass Cable w/ vol ctrl | eBay )

The replacement POD they sent me was PID# R108 and didnt work. Nothing happend when I pressed ON power, no light in the display and no light on the ON/OFF button.

After randomly pressing the buttons on the new POD, the display went on, but only the light, no symbols.

SO, My question to you all who have been successfully hacking your pods is:
Can I in some way get the R108 POD to work with my R514 Z-5500 system?
...or is the only solution to by a replacement cable as in the ebay link above?

/Q

You probably have to replace D18.
Good luck
