OWNER’S MANUAL THANK YOUVERY MUCH FORPURCHASING
THIS BMB SPEAKERS SYSTEM. BEFORE USE,
PLEASE READ FOLLOWING INSTRUCTIONS
THROUGH CAREFULLY AND FAMILIARIZE
YOURSELF WITHTHE OPERATIONOF THE
SYSTEM.
BEFORE USE
Operating Precautions
The maximum input power of these speakers is 450 W (at peak). Higher levels of input power may cause damage to
the speaker system and so take every precaution to keep the power down to the specification.
Even if an amplifier with a maximum output power of less than 450 W is employed, do not use the speakers with the
volume turned up too high or the sound distorted. This may damage the speakers.
Make sure that the amplifier’s power switch is at the OFF position when connecting the speakers to the amplifier.
Make sure that the amplifier’s volume control is turned down to its lowest setting when the amplifier’s power switch
is set to the ON position.
CONNECTIONS
INSTALLATION
Make sure that you set the power switch on the amplifier to the OFF position when connecting the speakers to the
amplifier.
Align the (–) and (+) polarities of the speakers with the (–) and (+) polarities of the left (L) and right (R) channels of
amplifier, and connect the speakers to the speaker terminals on the amplifier.
* If the polarities of the left and right speakers are not aligned properly, the quality of the reproduced sound, the
ambience and the feeling of direction will all be markedly impaired.
* When making the connections, take every precaution to prevent the speaker cords’ central cores from being
shorted.
Installing the Speakers
Avoid installing the speakers in a location exposed to direct sunlight and high levels of humidity.
Avoid also locations in the vicinity of stoves and other sources of heat.
With a speaker system, the sound which is heard varies greatly according to the installation location. Bear in mind
the following points in order to derive the most enjoyment from music.
) Install the speaker at the upper position than your ears level when you listen to the sound under normal listening
conditions.
) The best distance between the speakers is approx. 2 to 5 m.
) The bass sounds fuller if the speakers are installed on a solid and stable stand of shelf, or if they are placed
against a wall.
The bass sound will lose its impact if objects which do not reflect the bass well enough are placed in front of the
speakers.
If you plan to hang your speakers from the ceiling, contact a professional installer.
Caution:
If you want to suspend the CSN-455E from the ceiling, use adequate mounting hardware that can bear the load. In
addition, be sure to secure the mounting hardware onto a place of high-tensile strength using screws appropriate to the
ceiling materials.
MAINTENANCE OF CABINET
When the cabinets are dirty, clean off the dirt with a soft cloth. If the dirt is engrained, moisten a soft cloth in cold or
lukewarm water, wring it out, and then wipe off the dirt. Never use thinners or alcohol since these substances can
impair the finish of the cabinet. Also, avoid using insecticide and other sprays near the speakers.
Making Allowable Connections between Speakers and Your Amplifier (Ex. 4 Speakers)
Configure and wire the speakers so that the combined impedance falls within 6 to 32 Ω.
Note:
The specification allows the combined impedance ranging 4 to 32 Ω, however, 4 Ω configuration is not recommended; avoid it whenever
possible.
