User manual YAMAHA NS-45E

[. . . ] When using an amplifier with a rated output power higher than the nominal input power of the speakers, care should be taken never to exceed the speakers' maximum input. Do not attempt to clean the cabinets with chemical solvents as this might damage the finish. To prevent the cabinets from warping or discoloring, do not place the speakers where they will be exposed to direct sunlight or excessive humidity. [. . . ] Use the stands included with the speakers to increase stability: Be sure to use the stands regardless of where the speakers are positioned. Attaching the stands included with the speakers reinforces the base of the speaker not to fall over. Please be cautioned that even though the stands are connected, this does not guarantee that the speakers will not fall over. For safe and proper use of the speaker: Position the speaker in a location that is solid, level, smooth, and low (with respect to the floor). Do not push or apply pressure to the side of the speaker when moving, or lean objects against the side of the speaker. Do not sit on or set objects on top of the speaker. REMOVING THE FRONT COVER The front cover is fixed to the cabinet at six points, and can be removed if desired. To remove the cover, hold both sides and slowly pull straight away from the speaker. To reattach, line up the six pegs on the inside surface of the cover with the six corresponding holes on the speaker and push gently.

Speaker cord (4m) x 2 Stand x 8 Screw x 16 Leg x 8 * Specifications subject to change without notice due to product improvements. * Care should be taken not to exceed the input power values noted above. Note When the cover is removed, take care not to touch the speaker units with your hands or to exert excessive force with tools. CONNECTION TO YOUR AMPLIFIER BEFORE MAKING CONNECTIONS, MAKE SURE THAT THE AMPLIFIER IS SWITCHED OFF. s CONNECTIONS Connect the screw-type input terminals at the rear of the speakers to the speaker output terminals of your amplifier with the provided speaker cords. One side of the speaker cord is red and the other side is black. Connect the (+) terminals on both the amplifier and the speakers using this red side. Connect the (­) terminals on both components using the black side of the cord. Connect one speaker to the left (marked L) terminals of your amplifier, and another speaker to the right (marked R) terminals, making sure not to reverse the polarity (+, ­). If one speaker is connected with reversed polarity, the sound will be unnatural and lack bass. [. . . ] 2 Put another screw through the outside hole on the stand, and screw it into the inside hole on the base of the speaker. 4 Attach a leg to the bottom of the end portion of the stand. 5 Attach the other stands to the other corners of the base of the speaker in the same way and confirm that all 4 stands have been firmly attached.
