NOTICE

To avoid the possibility of malfunction/damage to the product, damage to data, or damage to other property, follow the notices below.

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.

• Be sure to observe the power amplifier’s rated load impedance, particularly when connecting speakers in parallel. Connecting an impedance load outside the amplifier’s rated range can damage the power amplifier.

• Protective Circuit

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.

Connectors

• Use only Neutrik speakON plugs (NL4) for connecting speakON connectors.

Parallel connection of speakers

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.

Installation Examples

CAUTION

• Before doing any installation or construction work, consult with your Yamaha dealer.

• 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.

Yamaha cannot be held responsible for damage or injury caused by insufficient strength of the support structure or improper installation.

Pullback point (only for CBR15 and CBR12)

• 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.

Troubleshooting

Symptom

No sound.

Howling sound is produced

(feedback).

The amplifier shuts down.

High frequency range is attenuated.

Possible causes

The protection circuit is operating in the HF unit.

Possible solution

The cable is not connected properly. • Connect the cable all the way in so that it is firmly in place.

• If the speakON connector is used, connect to “1+” and “1-” and turn the plug to be locked.

A microphone is directed toward the speaker.

Aim the speaker away from the area where the microphone picks up sound.

The sound is amplified too much.

Lower the volume of input device and locate the microphone more closely to the sound source.

The total impedance of the speakers is less than the minimum load impedance of the amplifier.

Example: More than two speakers

(eight ohms) are connected to a power amplifier, the load impedance of which is six ohms.

Check the minimum load impedance of the power amplifier, and lower the number of speakers connected in parallel not to be less than the impedance.

Refer to “Protection circuit” in the NOTICE.

If any specific problem should persist, however, please contact your Yamaha dealer.

Installation using eye bolts

Attach commercially-available eye bolts (M8 x 15 mm) to the screw holes located at the bottom (two locations) and on the upper rear (one location, only for CBR15 and CBR12). Keep in mind that you will need two points at the bottom to suspend the unit.

CAUTION

Make sure to use eye bolts according to the standards and safety regulations in your area.
