Samson airline micro camera is a great product; well designed, with a great sound quality, and a great battery life. I'm really satisfied with it, but there is one point I miss : since the link is one-channel, why is there a stereo jack on the receiver ? And on the dock ?
This is not really practical to me as I plus headphones to the receiver, and I want to hear the mono sound on the two ears.
I don't want to open the receiver for now and put my soldering iron onto it; but the dock is large and easy to open.
The goal of this instructable is to have a two-channels audio output from the dock, to hear in "stereo" with a headset.
Before: mono (channel left only)
After: double mono (channel left redirected to channel left and channel right)
Step 1: Step 1: Opening the Dock
Opening the dock is easy:
- remove the back rubber
- unscrew the 4 screws on the back
carefully separate the two plastics components
Step 2: Step 2: Unsolder - Solder
Opening the dock, we see how it's wired: direct.
- Left input -> left output
- right input -> right output
What we want is:
- left input -> left output and right output
- right input -> None
In my case, the wiring colors are:
- left: brown
- right: purple
- ground: red
There is two things to do here :
- remove the right channel cable
- join left and right outputs (I done it with a little bit of solder)
Step 3: Step 4: Close and Enjoy
This is all !
You can close the box, put screws again and enjoy "stereo" sound.
