This little device allows amateur radio operators to easily record mic and rig audio to separate channels of a 2-channel (stereo) audio recorder. Connect rig input via a 3.5mm TRS AUX cable which will be attenuated and provided to the recorder via another AUX cable on one stereo audio channel. Plug in a lavaliere mic to the mic input to record you talking. And plug in headphones to get binaural audio from the rig to your ears.
