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.

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.

Installation Examples

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.

Upper rear of the unit

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.
