Before you start

•The nominal impedance of this speaker system is 8 Ω. Connect the speaker system to an amplifier capable of driving an impedance of at least 8 Ω.

This product incorporates auto-resetting overload protection technology to help avoid damage to the speakers. However, please observe the following precautions:

•Do not supply amplification power to the speaker system in excess of the maximum permissible input, which could damage the speaker and cause a hazard from overheating.

•If using a graphic equalizer to boost sounds in the high-frequency range, do not use excessive amplifier volume.

•Do not try to force a low-powered amplifier to produce high sound levels as the amplifier’s harmonic distortion will be increased, and you may damage the speaker.

Caution: installation

•When installing the speakers, make sure that the wall/ceiling is strong enough to support the speakers.

•Improper installation of the speakers could cause them to fall and cause damage or injuries to persons nearby.

•Switch off and unplug your AV equipment and consult the instructions when connecting up components. Make sure you use the correct connecting cables.

•Keep magnetic objects such as screwdrivers or steel parts away from the tweeter and woofer speakers. Since the speakers use strong magnets, the objects may be attracted, causing injury or damaging the diaphragm.

•Do not install the speakers where they will be in direct sunlight, and avoid positioning them near heaters and air conditioners. This may cause warping and discoloration of the speaker and damage to the speakers.

•This speaker system is designed for home use only. To avoid electric shock hazard, do not place them outside, or in an overly humid area.

Caution: in use

•If the speakers stop emitting sound after receiving too large an input signal, turn down the volume control on the amplifier and wait a few seconds. The protection feature will be reset automatically.
