One controller pod...being split for two speaker sets?

I just recently had an issue with my 5500 set making a relative noise description that HOMEDOH was describing except mine was coming from the left rear. i called logitech and they said they would replace the whole unit but just for me to send them back the control pod and remote. i had to make sure he wasn't kidding... i send them the pod and remote and they send me a whole new set of everything..? whoa sweet ....but my question was having those extra speakers and a sub that still works..well except for the left rear buttt.... my question was is it possible to some how make one pod communicate with two 5500 speaker sets? i was looking at the connection for the pod and its nothing more than a kvm i was wondering if a kvm splitter would possible work. Assuming the splitter most likely has some diodes in it, it would be difficult for the power to get sent back from the amp threw the splitter and to the pod..another issue would be having both power signals coming from both subs to the splitter to the pod would most likely fry something. but because it would be a parallel circut it may not..? not 100% sure if any one knows please let me know

Re: one controller pod...being split for two speaker...

This whole post is completely incorrect. You must go to radio shack, buy 2 female, and 1 male 15 pin D-sub connectors. Than solder 15 wires (the largest guage you can fit) than split those wires in to 2 wires, making a Y connector. Than using an ohms meter to trace wires, tape and number each wire. than on the 30 wire ( 15 split into 2) solder wire 1 onto pin one of both female plugs, continue to do this to all 30 wires. once you get done let a glue gon get really hot and squirt glue into wires soldered onto plugs to help them hold on. The reason this works is because there is 18+ volts being sent and recieved amoung the amp and pod. You must have both systems plugged in, this will still allow the same amount of volts to be sent and recieved. This is time consuming, but it works Great! you will have 1000 watts of sub!! The volume doest get worse, there is no power issues. Im not sure if this is a logitech "tech" or what, but this blog is false. You must make your own Y splitter cable or special order them.


P.S. This isnt hard, do your research, know how it all works, and make sure you know how to solder!! Im 15 years old and figured this out.

Re: one controller pod...being split for two speaker...

Technically it's not a KVM connector.

A KVM switch uses a DB15 serial connector.  Just like a monitor uses a DB15 for it's VGA connection.

The pinout for the control center's DB15 connectori is not likely to be the same as either one of those two types of devices.

Unfortunately, there is no way to make one pod work with two sets of speakers. The reason for this is that the voltage supplied to the control center comes from the sub-woofer.  You can imagine having two sources of power connected to one, single control center...

The control center would not know which sub-woofer and power system to regulate.  You would end up with issues revolving around power distribution, volume levels being variable - or worse.  More than likely, you would either overload the control center or it would simply not be able to keep up with the demand for both systems simultaneously.

I myself just had my set of Z-5500's RMA'd to Logitech under the exact same circumstances.  I just received my new set today.  Retail box and everything.

He was NOT kidding you.  I had to make him repeat himself just like you did.  LOL.

But I sent the control center, remote and purchase receipt with them.

5 days later, I found out DHL almost had my package here.  (Although I was lucky.  The turn-around time on the RMA is subject to supply and demand.  I was quoted 6-8 weeks at one point due to their lot being completely empty.  They are manufactured and shipped from China according to the rep I spoke with...)

My advice to you is to get right on the RMA process.  Get your incident number from the Logitech rep who sets up your RMA.  Get those two pieces sent in as soon as you can.  Do what I did.

To do this, call the following number.

General Technical Assistance/RMA: 646-454-3200

Package the remote, control center into a box snuggly.  WRITE YOUR INCIDENT NUMBER given to you by the Logitech rep on the receipt.  Include the receipt in the box.  Take it to the post office and send it by USPS Priority mail.  Get "Delivery Confirmation" on it.  All told it came to just under $10 for me.

Send it to the following address:

Logitech Incorporated
6505 Kaiser Drive
Fremont, CA 94555
ATTN: Incident Number# <put your incident number here>

You will also be instructed to send a copy of your receipt by way of fax.  WRITE YOUR INCIDENT NUMBER AND PERSONAL INFORMATION ON IT BEFORE FAXING.  (Or at least on a cover letter.)  They're supposed to send you an email to let you know that they received the fax...but I never received one.  Good thing I included a second copy with the control center and remote...because that's the one they used for processing.

FAX: 702-269-3439

I have pics of the shipping order that came on the box, too.  If you would like to see this proof, let me know.  I'll be more than happy to post plenty of pics that show my old set (sans the control center of course...) and the new set.

But don't delay like I did.  Mine was two days away from expiration of the warranty before I sent in the parts.  LOL.

Any more questions?  Let me know.  :)

Try pulling the power from the unit for a few minutes, the reconnect. Make sure you've got the surround settings correct. If that doesn't do it, you've likely popped the amp or the amp's power supply in the sub box.

verify if the computer has a digital output that matches your speakers (5.1 or 7.1). Also, verify that the cable leading from the PC to the main speaker box is OK. Also, the speakers may come with an installation CD, so you'll need to install the accompanying control application.

Someone stole my sound touch control pod for my z-5500 surround sound speakers,where can I get a areplacement?

Logitech does not sell these seperately.. not in my country anyhow. You should also be aware, that there is several (at least two) revisions of these controllers, so you cant just just use any controller.. Check eBay.. and try to get one that has the same sticker on the back of the stand as yours. EG, mine is R750. Good luck!

Woofer popping

Sounds like a loose connection or a blown speaker. I would try just playing around with the wires to see if you can make it pop, if so, the wire you were messing with is the most likely culprit. Also, verify the sub cone has no damage or cracks. I am betting it i a bad connection or a loose wire.
