MOUNTING THE SPEAKER TO A CEILING KMS-3000/KMS-2500 OWNER’S MANUAL Karaoke Speaker System You can also use the screw holes on the top of the speaker for installing the speaker on the ceiling by using commercially available mounting brackets. To fix the speaker to a mounting bracket, use the screws inserted to the screw holes of the speaker as the factory default status. If you use the commercially available screws, use the screws that matches to the following specifications: Screw type.............................................. M8 Screw length.......... 35 mm (1-3/8") or more English Thank you for selecting the Yamaha Karaoke 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. •• 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. •• 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. 100 mm (3-7/8") •• 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. •• As this unit is heavy, whenever it is moved, two people are required to transport it safely. •• Placing the speaker too close to a CRT-type TV may impair the picture color or cause a buzzing noise. In this case, move the speaker away from the TV. This is not an issue with LCD and plasma TVs. •• When choosing a power amplifier for use with this device, make sure that the output power of the amplifier is lower than the power capacity of this device. Malfunction or fire may occur. •• Even if the output power of the amplifier is lower than the power capacity of this device (program), use of excessive input signals resulting clipping may cause damage to the device. Malfunction or fire may occur especially when the following sounds or noises are generated: –– feedback, when using a microphone –– continuous and extreme volume sound from a musical instrument –– extreme continuous distorted sound –– noise caused by plugging/unplugging the cable while the amplifier is turned on •• 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. 100 mm (3-7/8") Top panel Caution •• The required length of a screw differs depending on the mounting bracket to be used. Select a screw which is suitable for use with the mounting bracket and can be fully inserted into the hole on the speaker. •• As this product is heavy, do not attach them to thin plywoods or soft wall surface materials, as the screws may tear free from flimsy surfaces, causing the speaker to fall and be damaged, or result in personal injury. •• Do not fasten the speaker to the ceiling with nails, adhesives, or other unsound hardware. Long-term use and vibrations may cause them to pull free. •• To avoid accidents resulting from tripping over loose speaker cables, fix these to the wall along with the speaker. 70 mm (2-7/8") KMS-3000 KMS-2500 REMOVING THE SPEAKER GRILLE 1. Remove the side of the fabric speaker grille. 2. Put your hands inside from the sides of the fabric speaker grille and remove the fabric front speaker grille by pushing up the other side. CONNECTING TO YOUR AMPLIFIER Caution‌ BEFORE MAKING CONNECTIONS, MAKE SURE THAT THE AMPLIFIER IS SWITCHED OFF. Connect the cables as shown below. ■ How to connect the speaker cables 1 10 mm KMS-3000/ KMS-2500 (R) 4 2 ■ When connecting the speaker cable KMS-3000/ KMS-2500 (L) Tighten Loosen Rear panel 3 1. Remove 10 mm (3/8") of insulation, and twist the conductors. 2. 3. 4. 5. Loosen the terminal knob. 4. Remove the metal speaker grille. •• Make sure you connect the speakers with the correct polarity—positive (+) terminals to positive (+) terminals, and negative (-) terminals to negative (-) terminals. If you get them crossed over, the sound will be unnatural and lack bass. •• Refer to the owner’s manual that came with your amplifier. ■ When using a banana plug Banana plug Insert the bare wire. Tighten the knob and secure the cable. 2 Note Be careful not to scratch yourself with the edge of the speaker grille. 1 Test the firmness of the connection by pulling lightly. Note Do not insert the insulation into the hole. Sound may not be produced. 3. Remove the 4 screws that hold the metal speaker grille. Notes •• Do not let the bare speaker wires touch each other as this could damage the speaker or the amplifier.
