What Is “TRS?”
A typical momentary Foot Switch will connect to an instrument such as the SKX PRO by means of a plug
similar to the one shown below.
TRS is an acronym for Tip-Ring-Sleeve, and refers to the fact that a connecting plug can have more than
one connector. This means that more than one Foot Switch can be connected to the SK instrument,
thereby allowing you to control more than one function using the same Foot Switch jack. If you wish to
do this, you will need a Stereo Adapter which has a Stereo plug and two (2) Mono jacks.
NOTE: This type of adapter is also called a “splitter.”
Insert the Stereo plug into the FOOT SW jack on the SK instrument and connect a Foot Switch to each of
the Mono input jacks. In most cases, the Left (L) input jack will access the Tip function while the Right
® will access the Ring function.
You can also use a TRS cable to connect a dual-switch (example shown below) to one of the FOOT SW
jacks.
If you do this, one of the switches will be assigned to Tip mode and the other to Ring mode. However,
if you use a dual-switch which allows you to select either Latching or Momentary operation, be sure to
select Momentary to use the switch with the SKX PRO.
NOTE: The plug-in receptacles on some commercially available adaptors may be marked “TIP” or “A” and
“RING” or “B” for easier identification. Follow these markings when setting up your Foot Switches.
