Society).
XLR Balanced Wiring
Pin 1 = Shield
Pin 2 = Hot (+)
Pin 3 = Cold (–)
1/4" TRS Phone Plugs and Jacks
"TRS" stands for Tip-Ring-Sleeve, the three
connection points available on a stereo 1/4" or
balanced phone jack or plug. TRS jacks and plugs are

1/4" TS Phone Plugs and Jacks
"TS" stands for Tip-Sleeve, the two connection
points available on a mono 1/4" phone jack or plug.
They are used for unbalanced signals.
1/4" TS Unbalanced Wiring:
Sleeve = Shield
Tip = Hot (+)
1/4" TRS Insert Plugs and Jacks
When patching the T•231 into a channel's
insert jack, you may need to use a special 1/4" TRS
connector that uses the tip to send the signal to the
T•231, and the ring to return the signal to the channel.
The sleeve is the common ground (earth) for both
signals. These are both unbalanced signals.
