• Do not operate the device if the sound is
distorting. Prolonged use in this condition
could cause overheating and result in fire.
• Do not input excessively loud signals that
may result in clipping in the amplifier or
cause the following:
- Feedback, when using a microphone
- Continuous and extremely loud sound from
a musical instrument, etc.
- Continuous and excessively loud distorted
sound
- Noise caused by plugging/unplugging the
cable while the amplifier is turned on
Even if the output power of the amplifier
is lower than the power capacity of this
device (program), damage to the device,
malfunction or fire may occur.
• When choosing a power amplifier for use
with this device, make sure that the output
power of the amplifier is lower than the power
capacity of this device (see Owner's Manual,
Digital Version). If the output power is higher
than the power capacity, malfunction or fire
may occur.
Yamaha cannot be held responsible for
damage caused by improper use or
modifications to the device.
NOTICE
To avoid the possibility of malfunction/damage
to the product, or damage to other property,
follow the notices below.
Handling and maintenance
Do not expose the product to excessive dust
or vibration, or extreme cold or heat (such as in
direct sunlight, near a heater, or in a car during
the day), in order to prevent the possibility
of panel disfiguration, unstable operation, or
damage to the internal components.
When placing the speaker face down, always
place it on a flat surface.
When connecting at high impedance using
the optional speaker transformer, make sure
the audio signal is passed through an 80Hz or
above high-pass filter before being input to the
speakers.
Be sure to observe the amplifier's rated load
impedance (see Owner's Manual, Digital
Version), particularly when connecting
speakers in parallel. Connecting an impedance
load outside the amplifier's rated range can
damage the amplifier.
Protection Circuit
This speaker system has an internal protection
circuit that shuts off the speaker unit when an
PA-8 2/2
excessive input signal is applied. If the speaker
unit emits no sound, reduce the volume level of
the amplifier immediately. (The sound will return
automatically in several seconds.)
Air blowing out of the bass reflex ports is
normal, and often occurs when the speaker
is handling program material with heavy bass
content.
Do not place vinyl, plastic or rubber objects on
the product, since this might discolor the panel.
When cleaning the product, use a dry and
soft cloth. Do not use paint thinners, solvents,
cleaning fluids, or chemical-impregnated
wiping cloths.
