Installation Precautions; Cabinet Maintenance - Pioneer SP-BS21-LR Operating Manual

Using the SP-C21 as a Center Speaker
The loudspeaker may be positioned above or below the TV. For best results align the front of the loud-
speaker with the front of the TV. Due to the well-controlled vertical directivity, it is not normally necessary to
vertically aim the loudspeaker towards the listener. If, however, the loudspeaker is placed under the TV and
very close to the floor, then tilting upwards may be beneficial.
Follow the instruction for your receiver and set the center channel to NORMAL in Pro logic modes, or
SMALL in Dolby and DTS modes. This will ensure that any bass signals encoded in the center channel
are redirected to the front speakers or sub-woofer where they will be optimally reproduced. If you have a
choice, set the crossover frequency to 100Hz.
It is recommended to use a sound level meter to setup the center channel level from the receiver. Adjust
the receiver center volume until the center channel sound level is equal to that from the front left and right
loudspeakers. In the absence of a meter, initially set the level of each channel to be identical. All models in
the range have sufficiently close sensitivities such that this is a good starting point. Now play a wide selec-
tion of movies and listen carefully to the clarity of dialog, particularly in the presence of other effects such
as explosions. Adjust the level until the dialog is clearly but naturally presented.
For best results the loudspeakers should be positioned at or above ear level.

INSTALLATION PRECAUTIONS

• Do not install this speaker system near a stove or other heating appliance, or put it in a place exposed to
the sun. Such locations may cause the cabinet to change color and the speaker system to break down.
• Remember that the SP-FS51-LR, SP-BS21-LR, and SP-C21 are quite heavy, so it is dangerous to install
them in high places such as on walls or pillars or in other unstable locations unless suitably secured in
place.
Pioneer will not be responsible for any accidents or damage that may result from
improper installation.
The SP-C21 is magnetically shielded. However, if the speaker system is installed too close to the screen of
a television set, color distortion may occur.
If this happens, turn off the power switch of the television set, and turn it on after 15 to 30 minutes. If the
problem persists, place the speaker system away from the television set.

CABINET MAINTENANCE

• Use a polishing cloth or dry cloth to wipe off dust and dirt.
• When the cabinet is very dirty, clean with a soft cloth dipped in some neutral cleanser diluted five or six
times with water, and then wipe again with a dry cloth. Do not use furniture wax or cleaners.
• Never use thinner, benzine, insecticide sprays and other chemicals on or near the cabinets, since these
will corrode the surfaces.
