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.
