BEFORE USE
Operating Precautions
● The maximum input power of these speakers is 1200 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 1200 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
● 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. (Please refer to the below drawing.)
SPEAKER SYSTEM
OWNER’S MANUAL
CSD-2000(SE)
*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.
INSTALLATION
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.
a) Install the speaker at the upper position than your ears level when you listen to the sound under normal listening
conditions.
b) The best distance between the speakers is approx. 2 to 5 m.
c) 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 CSD-2000(SE) 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.
