●Avoid using your amplifier and speaker in the following locations
to prevent possible damage:
•In direct sunlight or next to heating equipment.
•Extremely cold or hot locations.
• Locations exposed to high humidity or excessive dust.
• Locations subject to strong shocks or vibration.
●Avoid installing this unit where foreign object may fall onto this
unit and/or this unit may be exposed to liquid dripping or
splashing. On the top of this unit, do not place:
•Other components, as they may cause damage and/or
discoloration on the surface of this unit.
•Burning objects (i.e. candles), as they may cause fire,
damage to this unit, and/or personal injury.
• Containers with liquid in them, as they may fall and liquid may
cause electrical shock to the user and/or damage to this unit.
●If one of the following occurs, disconnect the cable from the
INPUT jack as soon as possible then contact the dealer from
whom you purchased the device for repair.
• The speaker cable or plug has become damaged.
•Sound is not produced or an abnormal smell or smoke is
present.
•A foreign substance gets into the device or liquid is spilled
onto the device.
• The device is wet or damp (rain, etc.).
•An abnormality or damage is found on the device.
●Before making any connections, make sure that the power on
the amplifier and any external devices is switched OFF.
●To protect the speaker from possible damage, always set the
OUTPUT knob to “0” before switching the power ON/OFF.
●When connecting the speaker jack to a speaker, use only a
cable designed specifically for connecting a speaker to the
amplifier. The use of any other cable can result in fire.
●Even if the device’s main power switch is switched OFF, power
is not cut off from the device. Place the device close to an easily
accessible electric outlet so it can be plugged in or unplugged
with ease.
●Your Yamaha amplifier is a precision musical instrument. Handle
it with care and avoid dropping or bumping it.
●Do not apply excessive force to the switches and controls.
●To prevent damage and possibly electrical shock, never open
the case and tamper with the internal circuitry.
●Do not block the ventilation ducts. The device is designed with
ducts on the front and back to prevent temperatures from rising
inside the device. Blocking the ducts will cause heat to buildup
inside the device, which may result in fire.
●Never place the device on an unstable surface, table, or sloped
surface. Also, never stack the device excessively. Doing so may
cause the device to fall or overturn, causing injury.
*If the device is to be stacked, we recommend that the casters be removed
from the amplifier/speaker to prevent overturning.
●During thunderstorms, switch off the power as soon as possible
and unplug the device from the electric outlet. If there are
lightning strikes, do not touch the power cable if it is still
connected to the electric outlet. Doing so can result in electric
shock.
●For safety, always remove the power plug from the AC wall
outlet if there is any danger of lightning striking in your area.
●Do not use the amplifier for any other purpose than powering a
speaker system.
Precautions
●Keep the amplifier away from neon signs or fluorescent lighting
to prevent noise pickup.
●Never use benzene, thinner or other volatile liquids for cleaning,
as these chemicals may cause damage or discoloration to the
finish. Always use a dry, soft cloth to wipe off dust and dirt.
To protect your speakers
The following may cause damage to speakers:
•Feedback caused when using a microphone.
•Continuous high sound pressure level produced by elec-
tronic instruments.
•Continuous high-power output distorted signals.
•Popping noises caused by turning on equipment, or by
connecting or disconnecting system-components while the
amplifier is turned on.
Operating Cautions!
To use in a safe manner, please obey the following
● About the XLR jack’s polarity
The pin order of the XLR type connector is as follows:
1: Shield (GND), 2: Hot (+), 3: Cold (-)
This conforms to the IEC60268 standard.
● About Cellular Phone Interference
Cellular phones used in close proximity to the device may
cause noise. If this is the case, move the phone a little away
from the device.
CAUTION!
Attaching and removing the casters
(BBT500-115 only)
When attaching the supplied casters, make sure that the
caster’s shaft is inserted all the way into the receptacle on the
bottom of the cabinet. Also, make sure that all four casters are
attached to ensure stability.
Using the cabinet with loose or poorly attached casters will
result in a condition that is unstable and hazardous, and cause
the cabinet to fall over, etc.
Insert the shaft until
it is no longer visible.
