@Meteoris Hi. I have a Z5500 (bought a year ago). The control pod failed and got it warrantied so I'm now using the Z5500's with a bypass cable. For some reason though the front left channel is about 20dB (about 90%) quieter than the other channels. I tried two different bypass cables and its' the same result. What could this be? A blown opamp?

@arshamskrenes YUP!

Thanks. Problem is there are 2 versions. Pods with pid #'s 635 and down pods with pid #'s 636 and up. I have no idea why Logitech would do this but the lower numbered pods won't work with the higher ones and the higher numbered pods won't work with the lower ones. Crazy!

[Meteoris]

@WhippJunior Not necessarily... my Z5500 has basic functions in those wires... there's nothing digital over the wire so it should be just fine working with any other pod. Basically, the POD that I have does some heavy DSP on it's own, passes by the signal back to the amps and commands them to mute or not when it's the case and that's all. If all PODS do this... then it's the same with all...

[WhippJunior]

Great Post! Quick question. Is there any way to make an older pod work with a newer version speaker and vice versa?

[Meteoris]

@WhippJunior I don't see why it would not be possible :-) The problem is understanding the wire functions which are very specific. But I would assume that the same function is performed by both pods... so yes... I would say that it's definitely possible!

@WhippJunior You are right, they do have different pinouts for different pids. I also have a post 636 system which is "headless" (no control pod). After reading the posts, I found a z-5500 bypass cable on ebay and got my speakers work again! If yours is the RCA version (probably pre 636 PIDs?), the pinouts might be different, you might also find a bypass cable for your system on ebay. Hope this helps!

@Meteoris Hi! I wonder: What PID does your device have and if you could possibly take your time and make a spreadsheet of the things you wired. I have the same inside components like your and i have not found any good threads about this model. Just pm me if you have some spare time to do the spreadsheet.

Hello and thanks for sharing.

All TDA are hot (not too much, but hot) without any sound coming out, do you think I have to change them all? Control POD seems to be fine. TDA chips are very hard to deseoldering (non lead solder), any advice to desoldering this??
