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

Handling and maintenance
- Do not expose the product to excessive dust or vibration, or extreme cold or heat, in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the internal components.
- Do not touch the speaker driver unit, since it might cause malfunction.
- Be sure to observe the amplifier’s rated load impedance (see page 108), particularly when connecting speakers in parallel. Connecting an impedance load outside the amplifier’s rated range can damage the amplifier.
- When cleaning the product, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths, since this might cause alteration or discoloration.
- Air blowing out of the bass reflex ports (hole or holes at the front) is normal and often occurs when the speaker is handling program material with heavy bass content.
- Do not place the speaker face down.
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.

Controls and Connectors

Rear

[INPUT/PARALLEL] connectorsThese are speakON connectors (Neutrik NL4) for connection to a power amplifier or a powered mixer using a speaker cable. Use only Neutrik NL4 plugs for connecting speakON connectors.

CAUTIONUse only speaker cables for connecting speakers to the speaker jacks. Use of other types of cables may result in fire.

NOTEFor the CHR12M, [INPUT/PARALLEL] connectors are included on both sides.

Bottom/sideTiltable pole socket (CHR15)CHR15 has two pole sockets on the bottom. You can choose the angle of the speaker so that it is positioned horizontal to the floor or tilting down toward the floor by 7 degrees. These sockets adapt to commercially available speaker stands and speaker poles of 35 mm diameterPole socket (CHR12M, CHR10)CHR12M has a pole socket on the side and CHR10 has one on the bottom.

Connection

WiringMake sure to wire the plugs as shown below.

Neutrik speakON plug (NL4)Parallel connection of speakers[INPUT/PARALLEL] connectors are connected inside in parallel. The first CHR receives the signal from an amplifier (such as a power amplifier, a powered mixer, etc.) by one of the [INPUT/PARALLEL] connectors, and routes the signal to the second CHR from the rest of [INPUT/PARALLEL] connectors.When connecting CHRs in parallel, be sure to check the load impedance the amplifier can drive. The nominal impedance of one CHR is eight ohms and the total impedance of two parallel connected CHRs is four ohms. In this case, the amplifier must be able to drive less than four ohm load impedance

Invalid connectionDo not connect the input from the amplifier to both the [INPUT/PARALLEL] connectors simultaneously. This creates a dangerous short circuit

Installation Examples

CAUTION

Before doing any installation or construction work, consult with your Yamaha dealer.
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 precautionary measures using wires to prevent the speaker from falling down in the event of an installation failure.
When installing the 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.
Make sure to use eye bolts according to the standards and safety regulations in your area

NOTEWires can be attached to the screw holes for eye bolts and to the screw holes for the U-bracket (CHR10 only) located at the center of the handle. The illustration below is an example of using the Unbracket.

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

Suspended Installation Using Eye Bolts (CHR15 and CHR10 only)Attach commercially available long eye bolts (30–50 mm in length) to the screw holes located at the top (two locations) and on the lower rear (one location). The screw diameter is M10. Keep in mind that you will need two points at the top to suspend the unit.

Pullback point
Securing the eye boltsRemove the flat-head screws tightened at the time of factory shipment, and then insert the eye bolts through the washers when attaching them

NOTEThe screw holes for eye bolts go through the cabinet wall. When not using eye bolts, tighten the flat-head screws in order to prevent air leaks

Suspension angleThe strength of an eye bolt differs depending on the suspension angle. Make sure to use eye bolts within a range of 0 to 45 degrees from a right angle (as shown).Correct: Within 45° from a right angleIncorrect: Do not suspend the eye bolts as shown in the illustrations below.Installation Using a Dedicated U-bracket (CHR10 only)

CHR10 can be neatly installed on a ceiling or a wall, either horizontally or vertically, with the separately sold Yamaha UB-DXRDHR10 U-bracket. For instructions on installing the U-bracket, refer to the corresponding manual for the UB-DXRDHR10.

NOTEThe UB-DXRDHR10 can be used together with separately sold optional brackets, such as the Yamaha BBS251 Baton Bracke

Also, the CHR10 features a rotatable horn (90 degrees). When shipped from the factory, the directivity of CHR10 in a vertical orientation is the setting which makes the sound expand in a horizontal direction, and inhibits or narrows the sound in a vertical direction. We recommend changing the directivity by rotating the horn when you want to install the CHR10 horizontally and broaden the directivity.

Installation Examples

Rotatable Horn (CHR10 only)

Using a No. 2 Phillips head screwdriver, remove all fixing screws on the grille, and remove the grille from the speaker
Using a No. 2 Phillips head screwdriver, remove all screws installed on the horn and pull the horn out from the speakerNOTEMake sure not to push the screws too strongly with the Phillips head screwdriver. This may cause the nuts inside the cabinet to fall off

Rotate the horn 90 degrees, and re-install the horn to the speaker, reversing the steps above.Troubleshooting

Symptom	Possible causes	Possible solution
No sound.	The cable is not connected properly.	• Connect the cable all the way in so that it is firmly in place.• Connect to “1+” and “1–” and turn the plug to be locked.
Howling sound is produced (feedback).	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 amplifier shuts down.	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.
High frequency range is attenuated.	The protection circuit is operating in the HF unit.	Refer to “Protective Circuit” in the NOTICE (page 3).

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