CAUTIONS: READ THIS BEFORE OPERATING YOUR UNIT CONNECTIONS TO THE AMPLIFIER In order to maintain the speaker cabinet’s finish, prevent it from coming into contact with water vapor, alcohol, ben- zene, insecticide, etc. Do not place plastic coverings on top of the speakers as the color could come off and stick to the finish. To clean, wipe with a dry, soft cloth. To prevent the enclosure from warping or discoloring, do not place the speakers in places where they will be exposed to direct sunlight or excessive humidity. Do not place the speaker where they are liable to be knocked over or exposed to falling objects. Furthermore, stable placement will also ensure good sound. Placing the speakers on the same stand or shelf as the turntable can cause howling. These speakers feature a magnetically shielded design, but there is still a chance that placing them too close to a TV set might impair the picture colors. Should this happen, place the speaker away from the TV set. Never touch the speaker units with your hands or expose them to excessive shock. If they are dented or bent, the sound will be distorted as well. When an amplifier with a rated output power higher than the recommended power of the speaker system is used, care should be taken never to exceed the speaker's maximum power input. Connections to the amplifier speaker terminals depend on the particular amplifier you are using. Please check the amplifiers owners manual before making speaker connec- tions. To avoid any damage to the speaker system or amplifier, make sure to turn off the power of the amplifier when mak- ing speaker connections. * Before making connections, make sure that the amplifier is switched off. HB CONNECTIONS * Using speaker cable supplied, connect the center speaker output terminal of the amplifier and the input terminal of the back panel of this unit. * Connect the (+) terminals on both amplifier and speaker.
