* Please keep this manual in a safe place for future reference.

 

• 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.
- Make sure to use the specified hardware. 
- Inspect the device periodically.

• When transporting or moving the device, always use two or 

more people. Attempting to lift the device by yourself may 
damage your back, result in other injury, or cause damage to 
the device itself.

• Before moving the device, remove all connected cables.
• Do not expose the device to excessive dust or vibrations, or 

extreme cold or heat (such as in direct sunlight, near a 
heater, or in a car during the day) to prevent the possibility of 
panel disfiguration or damage to the internal components.

• Do not place the device in an unstable position where it 

might accidentally fall over.

• 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.

• Use only speaker cables for connecting speakers to the 

speaker jacks. Use of other types of cables may result in fire.

• When choosing a power amplifier to use with your speakers, 

make sure that its power output matches the speakers’ 
power capacity (refer to the Specifications on page 14). 
Even if the amplifier’s power output is lower than the 
speakers’ power capacity, the speakers may be damaged 
when clipping of a high input signal occurs. The following 
may cause damage to speakers:

- Feedback caused when using a microphone.
- Continuous high sound pressure level produced by electronic 

instruments.

- Continuous high-power output of distorted signals.
- Popping noises caused by turning on equipment, or by 

connecting or disconnecting system components while the 
amplifier is turned on.

• 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.

• Do not operate this device at high volume levels or at a level 

that is uncomfortable, since it is capable of producing sound 
levels that could cause permanent hearing loss. If you 
experience any discomfort or ringing in the ears, or suspect 
an hearing loss, you should consult an audiologist.

* Illustrations herein are for explanatory purposes only, and 

may not match actual appearance during operation.

or registered trademarks of their respective companies.
