The TRS Connector

While there is some risk in degrees of accuracy, Wikipedia can explain TRS connectors better than me. Hint: Larger guitar cables have this in common with the usually-smaller headphone cables. Another hint: While the black rings often tell you whether a given cable is mono (one black ring), stereo (two black rings), stereo + video (three rings), or stereo + power (three rings), the rings are merely insulation to separate the important metal contacts that actually do the dirty work. Just hope that the work a TRS connector cable does is not so dirty as it is crystal clear quality.
