Yes. It does require a FROM and another TO device.
RECAP does not record audio to itself.
RECAP S (the original RECAP): Stereo output. Left Channel: other party; Right Channel: your voice
pin out of output: tip: other party; ring: your voice; sleeve: ground
RECAP C (aka RECAP 2): Mono output. Both your voice & other party in same channel
pin out of output: ring: ground; sleeve: both your & other party's voice
RECAP C has not been tested to record to a PC. I recommend RECAP S for that use.
