Unhappy Help replacing/building a control unit

Hi ya,

I just moved home and lost my creative inspire 4.1 4400 sound control unit. I looked online to find it and didn't find any, also did some search and came to know that Creative doesn't provide these spares. Please help me build it or an alternative, till then my PC sound is as good as dead.

Thanks,
Siddu

I guess it is difficult to tell what circuitry was inside that sound controller unit unless one owns and dissects it.

If there is only a potentiometer then it's the best to open the cabinet carefully taking precaution and understand the sections and post some pictures here so that the experts can guide you.

A control unit for sure can be made imho once you know which chips are used in that.

All the best.

Hi Csom,

Thanks for getting back to me and luckily I have a friend who has got the same sound system and I borrowed his control unit to take some pics. Please help me build one like this.

It appears to be a dual potentiometer with single-pole switch, and an LED and resistor (probably to limit current through the LED). You need to trace out the circuit, buy the bits and build a copy.

Is there a way to just connect some wires together and get the device to turn on and running? Am happy to control the volume from the PC.

Here is an idea on how to do that. Also it would be convenient if we could know what chip was used in the power amp section.

IMPORTANT: This might be a DC volume control. So please read the attachment minutely.

All the very best

Probably, yes. Ignore the wires which go to the resistor, LED and switch - all they do is light the LED. Connect the input (top of pot) to output (pot slider). Connect the input ground to output ground.

Hello, this may have been solved long ago, but just in case I have found someone that has done something similar to what you are attempting here

Diya's life and journey through India...: A Quick Fix For Creative Inspire 4.1 4400 Speaker Volume Control Unit

Maybe you can help me. I do have the volume control unit, but it is cut on the miniDIN connector side.

So I have the original potentiometer on one side, and a bunch of cables on the other side: yelow, red, green, black, white.

Click the image to open in full size.


I assume I can buy a 6 pin male miniDIN connector and solder the cables to it, but... in which order? what colors where?


Thank you for your help.
