1/4" 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.

Loudspeaker Cable
Use loudspeaker
cables with a minimum
conductor size for the
length you need as
listed in these tables.
This will minimize power
losses to less than 0.5
dB. The cable lengths
listed are “up to”
lengths. For in-between
lengths, use the next
larger conductor
gauge. Using larger
than the recommended
conductor size is
always permissible.
Using smaller than
recommended conductor size will result in higher power
losses.
The recommended conductor gauges are listed for
AWG (American Wire Gauge) and Metric WG (Metric
Wire Gauge). Note that smaller AWG numbers = larger
conductors and smaller Metric WG numbers = smaller
conductors. The Metric WG is equal to ten times the
nominal conductor diameter in millimeters.
Longer Lengths
For cable lengths over 200 feet / 60 m at 8 ohms, and over
100 feet / 30 m at 4 ohms, the conductor sizes needed
for less than 0.5 dB power losses are rarely practical for
physical and cost reasons.
As a practical compromise for these situations the
recommended conductor gauge is 10 AWG or 25 metric.
6. CONNECTIONS
Use a high-quality 3-conductor shielded cable to connect
the signal between the signal source (mixing console,
equalizer, etc.) and the balanced inputs to the amplifi er.
If you are using unbalanced inputs, use a high-quality
2-conductor shielded cable. Here are some common audio
connectors and their internal wiring:
XLR Connectors
XLR connectors are commonly wired as follows (according
to standards specifi ed by the Audio Engineering 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 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.
