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):

      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.
