Raytraced image of two jack plugs, one mono, the other stereo. Numbers on details added, and image cropped afterwards in a graphics software package.
Numbers indicate:
Sleeve - usually ground
Ring - Right-hand channel for stereo signals, negative phase for balanced mono signals, power supply for power-requiring mono signal sources
Tip - Left-hand channel for stereo signals, positive phase for balanced mono signals, signal line for unbalanced mono signals
Isolating rings
