I have a Logitech Z 2300 system as well but have lost the volume control pod.

Is there a schematic of the pin-out used at the connection plug into the sub-woofer? Short of opening the sub-woofer box and tracing each connection to the appropriate end point.

The chances that it's the POT itself that failed are EXTREMELY low.

No, lost, as in not physically in my hand. I don't have it anymore.
So is there a schematic of the pinouts available?
There is a master volume control pot, so left and right channels - so 4 pins?
There is an amplifier subwoofer volume control pot as well so possibly another 4 pins?
There is the stanby on/off switch so possibly 2 more pins?
Probably two pins for the LED and two pins for the phone jack cutoff.
Any mapping would be great.

regarding replacement of the logitech z 2300 volume control pod / wired remote (soundtouch):


I have the information regarding the wiring diagram and a slightly simplified schematic generated by tracing the copper traces on the volume control PCB.

Unfortunately, it is not my work. Someone else performed the work and even built a replacement control board. Logitech says the wiring diagrams are "not a public document" (Z-2300 wired remote pinout - Logitech Forums there is a post by a logitech representative towards the bottom of this page).

Logitech will also not sell replacements.

I found out this information watching the youtube video YouTube - Replacement Control Pod for Logitech Z-2300

the user who posted the video, derivativeofjohn, will not release his wiring diagram publicly, due to the above logitech post. I am not sure if I am free to release it either, even giving him appropriate credit. (His website is JDS Labs)

You can contact him directly via YouTube private message. The video was posted in October of this year (2009) and he got back to me within a day or two. He asked me not to release the information due to Logitech's post, and since he runs an online electronics website, that could incite legal action from Logitech.

Depends on if they copyrighted the schematic or not. Reverse engineering the schematic is a whole lot of sketchy area legally, at least that I know of.

They should have them in stock and available for when ours fails.

In my case there is a crackling in the right speaker when I adjust the volume. And if I don't fine tune it just right, the right speaker doesn't have any output at all.

So frustrating

ok, first off there are no legal anything with this and if you think there is, your stupid.

There are 10 wires needed to make your very own controller and im going tell you what they do.

There was a guy that called it a VGA cable, well a VGA cable is a Sub D-15 so sure if you want to call it that great. the guy in the you tube vid used a Sub D-15 cable and it works just fine because that cable is st straight through.. pin 1 goes to pin 1 and pin 2 goes to pin 2 ect...

If you use a "VGA" (please NOTE THE GENDER BEFORE you cut) Cable cut

in half, the RED and BLACK and your StdBy and PGnd ( pin 5 & pin 15 )

connecting these will turn on your Logitech Z02300!

If you brake apart your pod controler this is what you will find inside.



| NAME | Color | What it is... | PIN| |


WA1 & WA2 |Black (big)| Are common or Ground.. Also Audio Ground | CASE |

StdBy | yellow | Turns on the Amp | #5 |

Vreg | Green | Voltage output ( connects to LED ) | #4 |

PGnd | Red | Power Ground |#15 |

LL | Blue | Left Line Input ( Audio + ) |#12 |

Sgnd | Black | Signal Ground ( Audio - ) Also Common Ground | #3 |

RL | Orange | Right Line Input ( Audio + ) | #6 |

Sline | Brown |Controls the Subs Gain via head phone return line | #1 |

LHP | White | Left Head Phone |#13 |

Rhp | Purple | Right Head Phone |#11 |





Ill Post More info if you guys want.

Line inputs are capacitor coupled

I found a DB-15 F connector and built my proto right off of it.

This is one i made just to make sure that It works.. and of corse it does...


illll try to make a schematic in paint and post it later.

Parts needed are as followed:

1 - 2kΩ Resistor
1 - 2.6MΩ Resistor
1 - 22MΩ Resistor
2 - 240Ω Resistor
2 - 5kΩ potentiometer
2 - .01µf (104k) Capacitors
1 - 3 volt LED (color of your choice =D )
1 - DB-15F connector
1 - Switching device (pin 5&15)
1 - stereo Audio connector (3.5mm - 1/8" or Stereo RCA.)

At Radioshack This will cost you around $18.27. They have everything you will need...

Note: If using as a SUB ONLY 6&3 get tied together and get capacitor coupled over ground instead of using the balanced method. This will Give you one input )

p.s. before you connect any audio sorce, Test your audio input for voltage...
My blue iPod Nano is now sounddddllleesssss!
