Before Mounting - Pioneer S-21W Manual De Instrucciones

• These speaker terminals carry
HAZARDOUS LIVE voltage. To prevent the
risk of electric shock when connecting or
disconnecting the speaker cords,
disconnect the power cord before touching
any uninsulated parts.
• After connecting the plugs, pull lightly on
the cords to make sure that the ends of the
cords are securely connected to the
terminals. Poor connections can create
noise and interruptions in the sound.
• If the cords' wires happen to be pushed out
of the terminals, allowing the wires to come
into contact with each other, it places an
excessive additional load on the receiver.
This may cause the amp to stop
functioning, and may even damage the
receiver.
• When using a set of speakers connected to
an receiver, you won't be able to obtain the
normal stereo effect if the polarity (+, –) of
one of the speakers (left or right) is
reversed.
Operation
• Set the receiver's cross-over frequency
at 200 Hz.

and surround speaker
system
Attaching the brackets
• When attaching the speakers to brackets,
always use the furnished brackets for wall
mounting.
• Make sure to tighten the supplied screw as
securely as possible when attaching the
bracket to the back of the speaker.
• Do not attach brackets to center speaker or
subwoofer.
• Use the M5 metric thread screw. Do not
use inch thread screw.

Before mounting

• Remember that the speaker system is
heavy and that its weight could cause the
wood screws to work loose, or the wall
material to fail to support it, resulting in the
speaker falling. Make sure that the wall on
which you intend to mount the speakers is
strong enough to support them. Do not
mount on plywood or soft surface walls.
• Mounting screws are not supplied. Use
screws suitable for the wall material and
support the weight of the speaker. If you are
unsure of the qualities and strength of the
walls, consult a professional for advice.
