OWNER’S MANUAL NS-M515 Speaker System English GR Thank you for selecting this YAMAHA NS-M515 speaker system. PRECAUTIONS Read this before using the speaker. ● To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference. ● Install the speaker in a cool, dry, clean place – away from windows, heat sources, sources of excessive vibration, dust, moisture and cold. Avoid sources of humming (transformers, motors). To prevent fire or electrical shock, do not expose the speaker to rain or water. PLACING THE SPEAKERS Place the speakers on a sturdy, vibration-free surface, on a well-built stand. ■ Using as 2ch stereo speakers Better stereo images will be obtained when the speakers are slightly angled in towards the listeners. ● To prevent the enclosure from warping or discoloring, do not place the speaker where it will be exposed to direct sunlight or excessive humidity. ● Do not place the following objects on the speaker: Glass, china, etc. If glass etc. falls by vibrations and breaks, it may cause personal injury. A burning candle etc. If the candle falls by vibrations, it may cause fire and personal injury. A vessel with water in it If the vessel falls by vibrations and water spills, it may cause damage to the speaker, and/or you may get an electric shock. ● Do not place the speaker where foreign objects such as water drips might fall. It might cause a fire, damage to the speaker, and/or personal injury. ● Do not place the speaker where it is liable to be knocked over or struck by falling objects. Stable placement will also ensure better sound performance. ● Placing the speaker on the same shelf or rack as the turntable can result in feedback. ● Never put a hand or a foreign object into the port located on the rear of the speaker as this might cause personal injury and/or damage to the speaker. ● When moving the speaker, do not hold the port as it might cause personal injury and/or damage to the speaker. ■ Using as main speakers in a multi channel system Position the speakers on both sides of the TV. The positioning of speakers is important, because it controls the whole sound quality of a multi channel system. Set up the speakers on the basis of your listening position by following the owner’s manual supplied with your amplifier. ■ Using as front effect or effect speakers Mount the speakers on a wall or place the speakers on a shelf. Determine the best position by following the owner’s manual supplied with your amplifier. NS-M515 (front effect) Center ● 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 speaker may be damaged. Subwoofer ● When using an amplifier with a rated output power higher than the nominal input power of the speaker, care should be taken never to exceed the speaker’s maximum input. ● Do not attempt to clean the speaker with chemical solvents as this might damage the finish. Use a clean, dry cloth. ● Do not attempt to modify or fix the speaker. Contact qualified YAMAHA service personnel when any service is needed. The cabinet should never be opened for any reasons. ● 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 speaker. NS-M515 ENG(02.08.21)a 1 NS-M515 (main) NS-M515 (rear effect) Note This speaker features a magnetically shielded design, but there is still a chance that placing it too close to a TV set might impair picture color. Should this happen, move the speaker away from the TV set. 02.8.21, 8:40 PM E-1  ■ To mount the speaker on a wall by using the attached mounting bracket Fasten screws into a firm wall or wall support as shown in the figure, and hang the holes of the mounting bracket on the protruding screws. * Make sure that the screws are securely caught by the narrow parts of the holes. You can also use the screw holes on the rear of the speaker for installing the speaker using a commericially available speaker bracket (if you do not use the attached mounting bracket). Screw holes Diameter: 4 mm Hole depth: 12 mm 60 mm Tapping screw (3.5–4 mm) (Available at the hardware store) Min. 20 mm 3 mm 40 mm Wall/ wall support WARNING ● This speaker weighs 5.0 kg (11 lbs.). Do not mount it on thin plywood or a wall with soft surface material. If mounted, the screws may come out of the flimsy surface and the speaker may fall. This damages the speaker or causes personal injury. ● Do not install the speaker to a wall with nails, adhesives, or any other unstable hardware. Longterm use and vibrations may cause it to fall. ● To avoid accidents resulting from tripping over loose speaker cable, fix it to the wall.
