-Avoid locations that are exposed
to
constant vibration
-
Use
the
required tools to install the device.
-
Inspect the device periodically.
Connections
•
Before connecting the device
to
other
devices,
turn off
the power for all devices. Before turn ing the
power
on or
off for all devices, set al
l
volume levels to minimum.
•
Use only speaker cables.
Use
of other types
of
cables
may result in
fire
Handling caution
•
Do
not
insert
your fingers or hands in any gaps or
openings on
the
device.
•
Do
not
rest
your
weight on the device or place heavy
objects on it, and avoid
use
excessive force on the
buttons, switches or connectors.
•
Do
not
use the
speakers for a long period of time at
a
hig
h
or uncomfortable volume
level.
since th is can
cause
permanent
hearing
loss.
If you
experience
any
hearing
loss or ringing in the ears, consult a physic ian.
•
Do not operate the device if the sound is distorting.
Prolonged
use in
this condition could cause overheating
and result in
fire
•
When choosing a power amp lifier for
use
with
this
device, make sure that the output power of the amplifier
is lower than
the
power capacity of
this
device.
If
the output power is higher than
the
power
capacity,
malfunction
or
l
ire
may occur.
•
Do not input excessively loud signals that may result in
clipping in
the
amplifier or cause the following:
-
Feedback,
when using a microphone
-
Continuous and extremely loud sound from a musical
instrumen
t, etc.
-
Continuous and extremely loud distorted sound
-
Noise caused by plugging/unplugging
the
cable while
the amplifier is turned on
Even if
the output
power
of
the
amplifier is lower than
the power capacity of this device (program). damage to
the device, malfunction
or

To
avoid the possibi lity of malfunction/damage to
the
product,
damage
to
data,
or damage to

follow
the
notices
below.
Handling and Maintenance
•
Do
not expose the
device
to excessive dust or
vib
ration,
or
extreme
cold or heat (such as in direct sunl ight
,
near
a heater, or
in
a car
during
the
day),
in order to prevent
the
possibility
of panel disfiguration. unstable operat ion.
or damage
to
the internal components
•
Do not
place
vinyl, plastic or rubber objects on the
device, since this might discolor the panel
•
When cleaning the device, use
a
dry and soft cloth.
Do not
use
paint
thinners, solvents, cleaning fluids, or
chemical-impregnated wiping cloths.
•
Condensation can occur
in
the
device
due to
rapid
,
drastic changes in ambient temperature-when the
device
is moved from one
location
to another,
or
air
conditioning is turned on or
off,
for
example. Using
the device while condensation is present can cause
damage.
If
there
is
reason to believe that condensation
might have occurred, leave the device for
several
hours
until
the condensation has completely
dried
out.
•
When
turning
on
the
AC power
in
your audio system,
always turn on the
power
amplifier
LAST,
to avoid
speaker
damage.
When turning
the
power off,
the
power amplifier should be turned
off
FIRST for
the
same
reason
•
Be sure to observe
the
power amp lifier's
rated
load
impedance
,
particularly
when connecting speakers in
parallel. Connecting an impedance load outside the
amplifier's
rated
range can damage the power
amplif
ier.
•
Protective Circuit
Al
l
full
-range
loudspeakers are fitted with a self-resetting
poly
switch that
protects
the
high-frequency
driver from
damage caused by excessive power. If a loudspeaker
cabinet loses high-frequency output,
immediately
remove power
from the power amplifier
and
wait for
two
to three minutes.
This
should be long
enough
to allow
the
poly
switch to
reset.
Reapply
power
and check
the
performance
of
the high-frequency
driver
before
continuing,
with
the power reduced to a
level
that
does
not cause the poly switch
to
interrupt
the
signal
•
Air
blowing
out of the bass reflex
ports
is normal, and
often
occurs when the speaker is handling program
material
with heavy bass content.
Connectors

Parallel connection of speakers
The
signals of
the phone
jack and speakON connector are
connected
in
paralle
l.
The
first CBR receives
the signal
from an
amplifier (such as a power
amplifier,
a powered
mixer,
etc.) with
the
phone jack or the
speakON connector, and routes the signal
to
the second CBR.
When
connecti
ng CBRs in parallel,
be
sure
to
check
the
load impedance the amplifier can
drive.
The
nominal
impedance of one
CBR is eight ohms and the
total
impedance of two
parallel
connected
CBRs
is
four
ohms. In this
case
,
the
amplifier
must
be
ab le to drive
less than four
ohm
load impedance.
