DESCRIPTION
One truth about working with audio is you always need the cable or adapter you
don't
have in
your toolbox. That's why we love these terminal-block audio connectors so much. No soldering
required! Use stranded or solid core wire and a small screw driver to create custom wiring jigs.
This is the 3.5mm (1/8") 4-Pole (TRRS) Audio Jack Terminal Block. TRRS stands for Tip, Ring,
Ring, Sleeve. It has four total pins - three signal and a ground as opposed to a more common
stereo jack's three. This type of connector is most often used in smartphones & cellphones to
provide stereo audio and one mic channel.
Note that the green block labels it as GND-blank-Right-Left which is the most commonly used
order. However, it would be more technically correct to just label it Sleeve-Ring-Ring-Tip: goes
in the same order as the four contacts on the plug.
We also have a (matching) 4-Pole Audio Plug Terminal Block.
