1/4" TS Phone Plugs and Jacks
“TS” stands for Tip-Sleeve, the two connections avail-
able on a mono 1/4" phone jack or plug. They are used
for unbalanced signals. It is okay to connect an unbal-
anced 1/4" phone plug into the 1/4" TRS phone jack on
the MR8.

Sleeve = Shield
Tip = Hot (+)
RCA Plugs and Jacks
RCA-type plugs (also known as phono plugs) and
jacks are often used in home stereo and video equip-
ment and in many other applications. They are unbal-
anced and electrically equivalent to a 1/4" TS phone
plug.
