Be sure the cables are wired per AES (Audio
Engineering Society) standards:
Balanced XLR Output Connector
Pin 1 – Shield (Ground)
Pin 2 – Positive (+ or hot)
Pin 3 – Negative (– or cold)
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)
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 micro phones. 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.

Balanced 1/4" TRS Connector
• Unbalanced send/return circuits. When wired
as a send/return “Y” connector, a 1⁄4" TRS jack
or plug is connected tip to signal send (output
from mixer), ring to signal return (input back
into mixer), and sleeve to ground (earth).
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
conection 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)
TS jacks and plugs are used in many different
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)
