INSTALLATION CONSIDERATIONS
RECOMMENDED AMPLIFIER POWER
For satisfactory performance, we recommend using a surround amplifier with
a power rating of 20-150 watts for the Pro770FX. We recommend an amplifier
power rating of to 20-200 watts for the Pro870FX. Most loudspeakers are not
damaged by large amplifiers, but rather by small amplifiers. If your system is
playing loud music, a small amplifier will run out of power very quickly and can
create damaging “clipping” distortions. A more powerful amplifier will play at the
same volume without distorting. See OPERATION on page 9 for more information
about amplifier clipping distortion.
LOUDSPEAKER WIRE
Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver
or amplifier. For most applications, we recommend using 16-gauge wire. For wiring
runs longer than 80 feet, we recommend 14-gauge wire. Every StageFront Pro
loudspeaker features gold-plated, five-way binding posts that will accommodate up
to 12-gauge wire directly. Larger sizes can be accommodated via pin connectors.
NOTE: THESE FIVE-WAY BINDING POSTS CAN BE CONNECTED IN SEVERAL DIFFERENT WAYS (E.G.,
BANANA PLUGS, SPADE TERMINALS, AND DIRECT WIRING).
When running wire inside walls or ceilings, use special jacketed cable (CL-2 or CL-3)
to protect the wire and to meet local electrical and fire codes. In some areas, conduit
is also required. For a trouble-free installation, low-voltage wire such as loudspeaker
wire must be run in accordance with the National Electrical Code and any applicable
provisions of the local building code. If you are unsure of the correct installation
techniques, wire jacket, or type of conduit to use, consult a professional audio/video
installer, building contractor, or the local building and inspection department.
TECH TIP
Wire size is expressed by its AWG (American
Wire Gauge) number – the lower the number,
the larger the wire. For example, 12 AWG is
physically larger than 14 AWG.
