IS1112(W) Owner’s Manual
• 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.
• Make sure to connect and neatly tie up the speaker cable so that the cable
is not exposed to being tripped over, stepped on or inadvertently pulled.
Also avoid pinching the cable (for example, between a heavy object and
the floor). Improper handling can result in damage to the device, personal
injury or fire as well as electrical shock hazard.
• Do not apply excessive input.
To prevent possible damage to the speakers or even fire, make sure to
immediately lower the input level in the following cases.
-
Feedback caused when using a microphone.
-
Continuous high sound level produced by electronic instruments.
-
Popping noises caused by turning on other equipment, or by connecting or
disconnecting system components while the amplifier is turned on.
-
Continuous high-power output of distorted signals.*
*The device may be damaged even when the output level of the power amplifier
is lower than the specified permissible input level, if distorted signals are
continuously output at high power.
• 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 for a long period of time 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.
• Do not stand on the device or put your feet on it, and do not hang it from
the ceiling or any high place. Improper handling can result in damage to
the device or even personal injury.
• If any unusual smell or smoke appears to be emitted from the device or
caused by it, or if there is a sudden loss of sound during use, or if the
device is dropped or damaged, discontinue using it immediately and have
it inspected by qualified Yamaha service personnel.
The rubber feet included in this package can be attached to the speaker to prevent it
from sliding when it is used on a slippery surface or if the speaker cabinet moves by
vibration at a high volume. See “Dimensions” (page 29).
Yamaha cannot be held responsible for damage caused by improper use or modifications to the device.
