Appendix B: Connections - Tapco 6912 Owner's Manual

Care and Maintenance
Your TAPCO loudspeakers will provide many years
of reliable service if you follow these simple guidelines:
• Avoid exposing the loudspeakers to moisture. If
they are set up outdoors, be sure they are under
cover if you expect rain.
• Avoid exposure to extreme cold (below
freezing temperatures). If you must operate the
loudspeakers in a cold environment, warm up the

Appendix B: Connections

Use heavy gauge, stranded wire for connecting
a speaker to the output of a power amplifier. Do not
use a guitar cord to make this connection. They
aren't designed to handle the high currents produced
by a power amplifier and can overheat.
As the distance between the amplifier and
speakers increases, the thickness of the wire should
also increase. Speaker wire has resistance, and when
electricity passes through a resistor, power is lost. The
thicker the wire, the less resistance it offers, and the
more power actually gets to the speaker.

through them for about 15 minutes prior to high-

• Use a damp cloth with a mild soap solution to
clean the cabinets. Avoid getting moisture into
any of the openings of the cabinet, particularly
where the drivers are located.
NL4-Type Plugs and Jacks
This connector is compatible with the popular
Neutrik® Speakon® 4-pole plugs. These connectors
are designed to handle the higher currents produced
by amplifiers, and have a locking feature to prevent
accidental disconnections. Simply line up the tabs
on the plug with the jack on the Series 69 connector
panel, push it in, and rotate it 1/4 turn to the right to
lock it in place.
