Hi,
I'm trying to mix three headphone level signals with a passive mixer and then use a small headphone amplifier to output to one pair of regular headphones (32 ohm impedance).
The passsive mixer is easy to build with resistors and and requires no power but for what I need, the headphone amp needs to be really small and powered by a single lipo cell.
I was looking at this https://www.ebay.com/itm/254884876406 but there's no US vendors of that product and I'm short on time for this project. Could you please recommend a similar single lipo cell powered, tiny headphone amplifier board that's readily available to ship from the US?
Thanks to everyone in advance!
