The Xbox Live Headset Amp was designed by me, nmcclana. I've always had difficulty hearing my friends on Xbox Live (maybe I'm deaf? Or maybe it's the crappy compression), so I made this project.
You can get the kit from Gadget Gangster. But, if you'd like to gather the parts yourself, you'll need the following.
- Resistor - 3.3k and a 10k Potentiometer
- A 2.5mm and 3.5mm Audio Jack
- Gadget Gangster project board (Boss Board)
- LM386 DIP
- 3xAA battery pack
- 220 uF cap
- hookup wire

Step 1: Wiring
Use a bit of excess wire to bridge the connections noted below - there should be 7 total connections. Also add the Audio amp as shown below. Pin 1 is between J24 - J25
Step 2: Jumpers & Resistor
Add jumpers as noted in the image below. Add the resistor from D18 - D22. It should be 3.3k (Red - Red - Red).
Step 3: Connectors
Now add the 2.5mm jack as on the photo. The 3.5mm jack fits right on the board in the box labeled [Pk]. The output cap goes at M22 - N22.
The potentiometer controls the volume. it goes at C22 - C24 - G23
Step 4: Finish Up
Last thing is to add power. Take the battery box, thread the wires through the board as shown on the photo and connect the power - the black wire goes to N2, and the red cable goes to O4.
You're all done! To use, flip the switch on the battery box, connect your headset to the 2.5 mm jack, and your controller to the 3.5mm jack. You'll need a 2.5mm dubbing cable, or use regular 3.5mm dubbing cable and a cell phone headset adapter.
Enjoy, and let me know how it goes! You can comment or order the kit on Gadget Gangster
