Appendix B: Connections
XLR Connectors
Channels 1 and 2 use 3-pin female XLR
connectors on the MIC inputs. They are wired as
follows, according to standards specified by the AES
(Audio Engineering Society).
XLR Balanced Wiring
Pin 1 = Shield
Pin 2 = Hot (+)
Pin 3 = Cold (–)
1/" TRS Phone Plugs and Jacks
“TRS” stands for Tip-Ring-Sleeve, the three
connections available on a stereo 1/4" or balanced
phone jack or plug. TRS jacks and plugs are used for
balanced signals and stereo headphones:
Balanced Mono
1/4" TRS Balanced Mono wiring:
Sleeve = Shield
Tip = Hot (+)
Ring = Cold (–)
Stereo Headphones
1/4" TRS Stereo Unbalanced Wiring:
Sleeve = Shield
Tip = Left
Ring = Right
1/" TS Phone Plugs and Jacks
“TS” stands for Tip-Sleeve, the two connections
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 (+)
RCA Plugs and Jacks
RCA-type plugs (also known as phono plugs)
and jacks are often used in home stereo and video
equipment and in many other applications. They are
unbalanced and electrically equivalent to a 1/4" TS
phone plug.
RCA Unbalanced Wiring:
Sleeve = Shield
Tip = Hot
1/" TRS Insert Plugs and Jacks
When patching an external device into a
channel’s insert jack, or the main insert jacks, you
may need to use a special 1/4" TRS connector
called an “Insert plug.” These use the
tip to send the
signal to the external device, and the ring to return
the signal to the mixer. The sleeve is the common
ground (earth) for both signals. These are both
unbalanced signals.
