V415010 NS-E55 NS-E55 m PRECAUTIONS SETTING UP THE SPEAKERS This model is designed to be used as an effect speaker system. Read these precautions carefully before using your speakers. c Any time you note distortion, reduce the volume control on your amplifier to a lower setting. Never allow your amplifier to be driven into “clipping”. Otherwise the speakers may be damaged. c 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. c Do not attempt to clean the speakers with chemical solvents as this might damage the finish. To clean, wipe with a dry, soft cloth. c To prevent the enclosure from warping or discoloring, do not place the speakers where they will be exposed to direct sunlight or excessive humidity. c Do not place the speakers where they are liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance. c Placing the speakers on the same shelf or rack as the turntable can result in feedback. c As these speakers contain strong magnets, avoid placing watches, magnetic tapes, etc. near them. Also, placing the speakers near a TV set may impair picture color. If this happens, move the TV set away from the speakers. c Secure placement or installation is the owner’s responsibility. YAMAHA shall not be liable for any accident caused by improper placement or installation of the speakers. n Mounting the speakers on a wall The speakers can be mounted on a wall by using the holes provided on the speakers’ back panels. Pads Holes Make sure that the screws are caught by a narrow part of the holes securely. Put the screws into a wall according to the figure shown below. 40 mm Fasten screws into a firm wall or wall support as shown in the figure below, and hang the holes on the protruding screws. Diam. 4 – 5 mm Min. 12mm 2mm Tapping screw (Available at a hardware store) Wall or wall support WARNING c Each speaker weights 2.2 kg (4 lbs. 13 oz.). Do not mount them on thin plywood or soft wall surface material, as the screws may come out of the flimsy surface, causing the speakers to fall down and be damaged, or result in personal injury. c Do not fasten the speakers to wall with nails, adhesives, or other unsound hardware. Long term use and vibrations may cause them to fall down. c To avoid accidents resulting from tripping over loose speaker cords, fix them to the wall. SPECIFICATIONS CONNECTION TO YOUR AMPLIFIER SPECIFICATIONS CONNECTION TO YOUR AMPLIFIER n CONNECTIONS c 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. c One side of the speaker cord has a gray line. Connect the (+) terminals on both the amplifier and the speakers using the side of the cord with the gray line. Connect the (–) terminals on both components using the side without a gray line. c 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. Procedures: . Loosen the terminal knob. . Insert the bare speaker wire end properly into the terminal hole. [Remove approx. 10 mm (3/8”) insulation from the speaker cord.] . Tighten the knob. . Test the security of the connection by pulling lightly the cord at the terminal.
