TRS, TRRS Jack plugs

New page

== TRS, TRRS Jack ==
TRS and TRRS are two types of jack plugs with 3 and 4 poles.

=== TRS Jack ===
A TRS Jack is a standard Jack plug used for a stereo headset. Typically it is 3.5 mm diameter, but also (tiny) 2.5 mm and (large) 6 mm exist.

TRS stands for Tip-Ring-Sleeve and denotes the three poles with sleeve being the inner pole next to the plastic/rubber cover of the plug.

The poles usage are standardised, all headsets and cables use same configuration.

=== TRRS Jack ===
A TRRS Jack is a jack plug with 4 poles, named from Tip-Ring-Ring-Sleeve, similar to the 3 poles TRS.

Depending on the type of device the extra pole may provide a composite video signal together with stereo sound.

Today (2011) many smart phones have a TV-out function that allow to display the phones display on a TV or video monitor using the Jack plug otherwise intended for headsets. The signal used is a composite video signal (SD resolution 15625 Hz line frequency). Note this is not a VGA like signal.

Unfortunately there is no clear standard pole configuration for this plug. There exists several configurations.
