Hi,
I'd like to DIY a simple device that uses one 9v battery to mix 4 iPads (4 inputs) that goes to 4 outputs that can drive 4 earbud-type earphones.
This is so 4 people could plug into this device and listen to one another.
Been looking at the headphone distribution amp schematics but they're usually either many inputs to single output (mixer) to one input to many outputs (distribution).
I'm a relative noob in electronics but can solder and have done audio kits before :)
Can someone please help?
Thanks!
