The K&K Sound special pickup sets, like the Bass Master Pro, Bass Master Rockabilly, Golden Trinity Mic Combos, etc., all use the two channel capability of this design to minimize the number of wires you need to get everything set up. So "Channel 1" and "Channel 2" are really just a similar concept to "Left" and "Right." But the two signals can be much more different - two different pickups, a pickup and a microphone, etc. While mostly we think of stereo as an paired version of the same signal (Left and Right "versions" of a music recording), in reality they are two distinct signals that happen to form a stereo image. You may have recognized that the design of the TRS plug is the same as the one on your stereo headphones for your iPod, smartphone, or other personal listening device - the stereo headphone jack works exactly the same way (although usually on a smaller, 1/8" or 3mm jack/plug). With bass pickup sets and certain preamps, we use this "stereo" capability to our advantage. The TIP carries hot channel 1, the RING carries hot channel 2, and the SLEEVE gets the ground signal from both channels (combining their grounds still keeps the two channels separate.)Īnd now you can probably figure out where the "TRS" name comes from ( Tip/ Ring/ Sleeve). This, again separated by the isolating rings (i), allows a second channel to be carried by the same cable. It adds a RING (3) to the TIP (1) and SLEEVE (2). The stereo cable builds upon this design. Simple, effective, and readily available, as they have been used on a kajillion guitars, basses, and other musical instruments around the world for decades. The TIP (1) carries the "hot" or positive audio signal the SLEEVE (2) is the ground or negative audio signal.
It has two conductors (1 and 2), separated by an isolating ring (i) so that they don't contact each other. The cable at the bottom of the graphic is a " standard" 1/4" instrument cable. They carry monophonic (single-channel) signals, such as a single pickup on a musical instrument.Ī TRS - aka "Stereo" - cable adds an extra connection, which allows the single cable to carry TWO channels of audio. Most standard 1/4" cables (guitar cables) have two conductors, like the one at the bottom of the photo to the right. The Difference Between Mono and Stereo Cables
