Precautions
AVOID EXCESSIVE HEAT, HUMIDITY, DUST
AND VIBRA TION
When choosing a location for your speakers, avoid the
following:
• Direct sunlight, high temperatures (such as near heaters), or excessively low temperatures.
• High humidity.
• Areas subject to excessive dust accumulation and
vibration.
• Non-level or unstable surfaces.
HOW TO POWER UP YOUR SOUND SYSTEM
To avoid damage to your speakers and other parts of
your system, when you turn on your system, ALWAYS
turn the power 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.
To protect your speakers
When choosing a power amplifier to use with your
speakers, make sure that its power output matches the
speakers’ power capacity (refer to the “Specifications” on page 5). Even if the amplifier’s power output is lower than the speakers’ PGM (program) power
capacity, the speak ers may be damaged when clipping
of a high input signal occurs.
The following may cause damage to speakers:
• Feedback caused when using a microphone.
• Continuous high sound pressure level produced by
electronic 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.
MAKE SURE THE POWER IS OFF BEFORE
MAKING OR REMOVING CONNECTIONS
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.
DISCONNECT CABLES BEFORE MOVING THE SYSTEM
To prevent short circuits or breakage of cables, always
disconnect cables prior to moving system equipment.
MATCH CONNECTOR POLARITY
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 impossible to achieve a
well-balanced sound field.
KEEP THIS OWNER’S MANUAL IN A SAFE
PLACE FOR FUTURE REFERENCE
This product, when used in combination
with amplification and/or additional
loudspeakers, may be capable of producing sound levels that could cause permanent hearing loss.
DO NOT operate at high volume le vels or
at a level that is uncomfortable. If you
experience any discomfort or ringing in
the ears, or suspect an hearing loss, you
should consult an audiologist.
SPEAKER HANDLES
The handles on your speakers are for transportation.
The F12M/F25/F28 models are not designed for suspension or hanging. Only the F12/F15 models are
designed for suspension. Please consult a qualified
engineer for proper hanging techniques.
