4-channel LM386-based headphone amp. i made this about 10 years ago and
while it's a little noisy its usage is flexible, fits nicely in 1 rack space,
and it runs off your trusty MOTM power supply. i will include schematics/project notes.
2 stereo unbal. sources:
- source 1 feeds headphone outputs a,b,c,d (simultaneously)
- source 2 feeds headphone outputs c,d (simultaneously)
i.e.
- outs A&B are fed only from stereo source 1
- outs C&D are switchable source 1 or 2
why i did this i don't know. it works, anyway.
