Yamaha R112C Manual De Usuario

• If you notice any abnormality, such as smoke, odor, or noise, 

turn the power amp off immediately. Remove the power cord 
from the AC outlet. Consult your dealer for repair. Using the 
unit in this condition is a fire and electrical shock hazard.

• When choosing a location for your speakers, avoid the fol-

lowing:
 - Direct sunlight, high temperatures (such as near heaters), 

or excessively low temperatures.

- High humidity.
- Areas subject to excessive dust accumulation and vibra-

tion.

- Non-level or unstable surfaces.

• To prevent short circuits or breakage of cables, always dis-

connect cables prior to moving system equipment.

• When using two or more speaker systems, be sure match the 

polarity (+/–) of the speaker system connectors to those at the 
amplifier. If the polarities do not match, the sounds produced 
by the speakers will interfere with each other, making it im-
possible to achieve a well-balanced sound field.

• This unit is heavy. Use two or more people to carry it.

• To avoid damage to your speakers and other parts of your sys-

tem, when you turn on your system, ALWAYS turn the pow-
er amp on last! This will avoid loud, damaging pops that will 
annoy your audience, and blow your speakers. When you 
power down, the amplifier should ALWAYS be turned off 
first to avoid the same problems.

• Always turn the power switches of system components OFF 

prior to connecting or disconnecting cables. Failure to do so 
may result in damage to speakers as well as to connected 
equipment.

•  Do not output distorted sounds for long periods of time, as 

this will cause the speaker to heat up, leading to a fire hazard.
