Short video on using the audio input on our orgone generators / radionics devices. In the video I use the pfc 2400 hd and demonstrate connecting to an iPhone with a 3.5 mm to lightning port cable ... Basically you get a cable, attach the 3.5 mm side to the audio input on the back of the orgone generator, attach the other side to your phone. Find anything you want to feed through the machine to be transferred to you ( a lot of room for experimenting) I demonstrate with a YouTube video with affirmations... feel free to share how you use the audio input
