Appendix B: Connections

Balanced XLR Input Connector
The 402VLZ4 mixer has two female XLR
inputs. Be sure the cables are wired per AES
(Audio Engineering Society) standards:
Balanced XLR Input Connector
Pin 1 – Shield (Ground)
Pin 2 – Positive (+ or hot)
Pin 3 – Negative ( – or cold)
Balanced XLR Input Connector
Balanced 1/4" TRS Connector
TRS stands for Tip-Ring-Sleeve, the three
connections available on a stereo 1/4" cable.
This allows for a direct connection to the
channel input jacks. Be sure the cables are
wired per AES (Audio Engineering Society)
standards:
Balanced 1/4" TRS Connector
Sleeve – Shield (Ground)
Tip – Positive (+ or hot)
Ring – Negative ( – or cold)

Balanced 1/4" TRS Connector
TRS jacks and plugs are used in several
different applications:
• Balanced mono circuits. When wired
as a balanced connector, a 1⁄4" TRS
jack or plug is connected tip to signal
high (hot), ring to signal low (cold),
and sleeve to ground (earth).
• Stereo headphones, and rarely,
stereo microphones and stereo
line connections.
When wired for stereo, a 1⁄4" TRS jack
or plug is connected tip to left, ring
to right and sleeve to ground (earth).
VLZ4 mixers do not directly accept
1-plug-type stereo microphones. They
must be separated into a left cord and
a right cord, which are plugged into
the two mic preamps.

You can cook up your own adapter for a
stereo microphone. "Y" two cables out
of a female 1⁄4" TRS jack to two male
XLR plugs, one for the right signal and
one for the left.
Unbalanced 1/4" TS Connector
TS stands for Tip-Sleeve, the two
connections available on a mono 1/4" cable.
This allows for a direct connection to the
channel input jacks. Be sure the cables are
wired per AES (Audio Engineering Society)
standards:
Unbalanced 1/4" TS Connector
Sleeve – Shield (Ground)
Tip – Positive (+ or hot)
Unbalanced 1/4" TS Connector
TS jacks and plugs are used in many dif-
ferent applications, always unbalanced. The
tip is connected to the audio signal and the
sleeve to ground (earth). Some examples:
• Unbalanced microphones
• Electric guitars and electronic
instruments
• Unbalanced line-level connections
Unbalanced RCA Connector
RCA-type plugs (also known as phono
plugs) and jacks are often used in home
stereo and video equipment and in many
other applications. RCA plugs are
unbalanced. Connect the signal to the center
post and the ground (earth) or shield to the
surrounding "basket." Be sure the cables are
wired per AES (Audio Engineering Society)
standards:
Unbalanced RCA Connector
Sleeve – Shield (Ground)
Tip – Positive (+ or hot)
