• When the unit is shipped from the factory, a seal is  
stuck on the pullback point (screw hole). Make sure to  
peel off the seal when using the pullback point.  
• The CBR10 does not have a pullback point.

For optimum safety, the installation should be checked thoroughly at regular intervals. Some fittings may deteriorate over  
extended periods of time due to wear and/or corrosion.  
When choosing the installation location, suspension wire and mounting hardware, make sure all are strong enough to  
support the weight of the speaker.  
Make sure to take measures to prevent the speaker from falling down in the event of a installation failure.  
When installing the safety wire to the wall, install it higher than the wire’s attachment point on the speaker, with as little  
slack as possible. If the wire is too long, and the speaker happens to fall, the wire may snap as a result of too much strain.  
• Insert the screw or eye bolt through the  
washer to attach them.

Always follow the basic precautions listed below to  
avoid the possibility of serious injury or even death  
from electrical shock, short-circuiting, damages, fire or  
other hazards.These precautions include, but are not  
limited to, the following:  
Max. 45°  
– Continuous and extremely loud sound from a musical  
instrument, etc.  
Use these M8 size screw holes for installing  
separately sold brackets or commercially  
available eye bolts.

Do not open  
Even if the output power of the amplifier is lower than  
the power capacity of this device (program), damage to  
the device, malfunction or fire may occur.  
• This device contains no user-serviceable parts. Do not  
open the device or attempt to disassemble the internal  
parts or modify them in any way. If it should appear  
to be malfunctioning, discontinue use immediately  
and have it inspected by qualified Yamaha service  
personnel.

CAUTION  
To avoid the possibility of malfunction/damage to the  
product, damage to data, or damage to other property,  
follow the notices below.  
Always follow the basic precautions listed below  
to avoid the possibility of physical injury to you or  
others, or damage to the device or other property.

Handling and Maintenance  
• Do not expose the device to excessive dust or vibration,  
or extreme cold or heat (such as in direct sunlight, near  
a heater, or in a car during the day), in order to prevent  
the possibility of panel disfiguration, unstable operation,  
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.  
Location  
• Do not place the device in an unstable position or fail  
to secure it properly in a potentially dangerous position  
where it may fall even if the position is horizontal. The  
device may accidentally fall over, resulting in damage  
and/or injury.  
• Do not use the speaker’s handles for suspended  
installation. Doing so can result in damage or injury.  
• Do not hold the bottom of the device when transporting  
or moving it. In doing so, you may pinch your hands  
under the device, and result in injury.  
CAUTION  
Wiring  
In order to prevent the unit from falling down, attach the safety wire as shown in the  
illustration.  
Make sure to wire the plugs as shown below.

may result in malfunction.  
Troubleshooting  
General Specifications  
1+ :  
1– :  
• Before moving the device, remove all connected cables.  
• Always consult qualified Yamaha service personnel if  
the device installation requires construction work, and  
make sure to observe the following precautions.  
– Choose mounting hardware and an installation  
location that can support the weight of the device.  
– Avoid locations that are exposed to constant vibration.  
– Use the required tools to install the device.  
– Inspect the device periodically.

Connections  
The signals of the phone jack and speakON connector are connected in parallel. 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 connecting 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 able to drive  
less than four ohm load impedance.

• Before connecting the device to other devices, turn off  
the power for all devices. Before turning the power on or  
off for all devices, set all volume levels to minimum.

may result in fire.

microphone picks up sound.  
All 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.  
The sound is amplified too much.  
Lower the volume of input device and locate the  
microphone more closely to the sound source.

• 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 high or uncomfortable volume level, since this can  
cause permanent hearing loss. If you experience any  
hearing loss or ringing in the ears, consult a physician.  
• Do not operate the device if the sound is distorting.  
Prolonged use in this condition could cause overheating  
and result in fire.
