BEFORE USE
* Please read this operating guide through before using
your speaker system so you will Know haw to make the
most of its performance. After you have finished reading
the operating guide, store the guide in a safe place. You
will then know where it is, should you wish to refer to it if
something is unclear while the speaker system is being
used
® The nominal impedance of this speaker system is 6 ohms.
Connect the speaker system to a stereo amplifier with a
load itripedance ranging from 4 to 16 ohms (a model with
"A 16 2" displayed on the speaker output terminals)
* in order to prevent damage to the speaker system
resulting from input overload, please observe the follow
ing precautions:
« Bo not supply power to the speaker system in excess of
the maximum permissible input
* When connecting or disconnecting pin-plugs, be sure
amplifier power is OFF.
* When using a graphic equalizer to emphasize loud sounds
over a high frequency range, do not use excessive
amplifier volume
* Do not try to force a low-powered amplifier to produce
loud volumes of sound (the amplifier's harmonic distor
tion will be increased, and you may damage the tweeter)
* Do not touch the speaker cones' reverberating surfaces
as they may be damaged by external force
@ When using a persorial computer with audio capability,
high frequency signals tend to be overly strong. There-
fore, attenuate high frequencies or use at flow volume
levets.
INSTALLATION
@ These speaker systems are magnetically shielded. How-
ever, depending on the installation location, color
distortion may occur if the speakers are installed ex
tremely close to the screen of a television set or monitor
fn this event separate the speakers farther from the
television screen,
@ This speaker systern includes speakers meant for installa
tion on the right, and thase for the left side. On the
back of the speakers can be found an L {left} or R
{right} indicating the side on which the speaker is to be
used, Viewed fram the listening position, place the L
speaker on the left, and the R speaker on the right side
(there may be cases where room conditions may result
in better results from reversing the installation positions).
# The ideal listening position is at or stightly beyond the
apex of an imaginary equilateral triangle with the
speaker system forming the base line.

e This speaker systern is designed as a book-shelf type.
When it is installed directly on the floor, reflected sound
from the floor surface may be increased, increasing the
bass and possibly making the sound unpleasant to
listen to. In this case, mount the speaker system on a
stand or concrete block to raise it ahove floor level. In
general, best results will be obtained if the speaker
system is installed so that the tweeters are on approxi-
mately the same level as the listener's ears.
INSTALLATION PRECAUTIONS
* Do not install this speaker system near a stove or other
heating appliance, and do not put it in a place exposed to
the sun. Locations like these may cause the cabinet to
change color and the speaker system to break down.
© Remember that this speaker system is quite heavy, so it is
dangerous to install it ina high place like on a wall or pillar
or in other unstable locations
