Attempting to lift the device by yourself may damage your back, result in other injury, or cause damage to the device itself. •• If you are not a qualified service technician, do not attempt to install the device. Always consult qualified Yamaha service personnel if the device installation requires construction work, and make sure to observe the following precautions. –– Choose mounting hardware and an installation location that can support the weight of the device. –– Avoid locations that are exposed to constant vibration. –– Use the required tools to install the device. –– Inspect the device periodically. Warning Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following: Do not open •• This device contains no user-serviceable parts. If you are not a qualified service technician, do not open the device or attempt to disassemble the internal parts or modify them in any way. If it should appear to be malfunctioning, discontinue use immediately. Inspection must be performed only by qualified Yamaha service personnel. Fire warning Connections •• Do not put burning items, such as candles, on the device. A burning item may fall over and cause a fire. •• Before connecting the device to other devices, turn off the power for all devices. Before turning the power on or off for all devices, set all volume levels to minimum. •• Use only speaker cables for connecting speakers to the speaker jacks. Use of other types of cables may result in fire. Caution Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the device or other property. These precautions include, but are not limited to, the following: Handling caution •• Do not insert your fingers or hands in any gaps or openings on the device (ports). •• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any gaps or openings on the device (ports) If this happens, turn off the power of external devices immediately and unplug the power cord from the AC outlet. Then have the device inspected by qualified Yamaha service personnel. •• Do not rest your weight on the device or place heavy objects on it, and avoid use excessive force on the buttons, switches or connectors. •• Do not use the speakers for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician. •• Do not operate the device if the sound is distorting. Prolonged use in this condition could cause overheating and result in fire. •• 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. If the output power is higher than the power capacity, malfunction or fire may occur. •• Do not input excessively loud signals that may result in clipping in the amplifier or cause the following: –– Feedback, when using a microphone Location •• Do not place the device in an unstable position where it might accidentally fall over. •• Do not block the vents. This device has a port at the bottom to prevent the internal temperature from becoming too high. In particular, do not place the device on its side or upside down. Inadequate ventilation can result in overheating, possibly causing damage to the device(s), or even fire. •• When installing the device: –– Do not cover it with any cloth. –– Do not install it on a carpet or rug. –– Make sure the top surface faces up; do not install on its sides or upside down. –– Do not use the device in a confined, poorly-ventilated location. Inadequate ventilation can result in overheating, possibly causing damage to the device(s), or even fire. •• Do not press the rear panel of the device against the wall. Doing so may cause the plug to come in contact with the wall and detach from the speaker cable, resulting in short circuiting, malfunction, or even fire. •• Do not place the device in a location where it may come into contact with corrosive gases or salt air. Doing so may result in malfunction. •• Avoid being near the device during a disaster, such as an –– Continuous and extremely loud sound from a musical instrument, etc. –– Continuous and extremely loud distorted sound –– Noise caused by plugging/unplugging the cable while the amplifier is turned on Even if the output power of the amplifier is lower than the power capacity of this device (program), damage to the device, malfunction or fire may occur. Notice To avoid the possibility of malfunction/ damage to the product, damage to data, or damage to other property, follow the notices below. Handling and maintenance •• Do not expose the device to excessive dust or vibration, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day), in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the internal components. •• Do not place vinyl, plastic or rubber objects on the device, since this might discolor the panel. •• When cleaning the device, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemicalimpregnated wiping cloths. •• During extreme changes in temperature or humidity, condensation may occur and water may collect on the surface of the device. If water is left, the wooden parts may absorb the water and be damaged. Make sure to wipe any water off immediately with a soft cloth. •• Be sure to observe the amplifier’s rated load impedance, particularly when connecting speakers in parallel. Connecting an impedance load outside the amplifier's rated range can damage the amplifier. •• Protective Circuit (poly switch) All full-range loudspeakers are fitted with a self-resetting poly switch that protects the high-frequency driver from damage caused by excessive power. If a loudspeaker cabinet loses high-frequency output, immediately remove power from the unit and wait for two to three minutes. This should be long enough to allow the poly switch to reset. Reapply power and check the performance of the high-frequency driver before continuing, with the power reduced to a level that does not cause the poly switch to interrupt the signal. •• Air blowing out of the bass reflex ports is normal, and often occurs when the speaker is handling program material with heavy bass content. 3-way 4-speaker bass reflex / Non magnetic shielding Type HF Components KMS-2600 MF1 MF2 LF 2.5 cm (1") horn type ×1 10 cm (4") cone type ×1 12 cm (5") cone type ×1 12 cm (5") cone type ×1 30 cm (12") cone type ×1 45 Hz to 30 kHz NOISE Power rating*1 PGM (IEC 100h) MAX Sensitivity (1W, 1m) Connector 47 Hz to 30 kHz 2 kHz, 3 kHz Crossover frequency Weight Finish 18.6 kg (41 lbs) 14.7 kg (32.4 lbs) Black PVC *1: IEC shaped Pink noise with 6 dB crest factor •• The contents of this manual apply to the latest specifications as of the printing 8Ω Nominal impedance Frequency range (-10dB) 25 cm (10") cone type ×1 Dimensions (W × H × D) KMS-2600 576 × 342 × 353 mm (22 11/16" × 13 1/2" × 13 7/8") 275 W 175 W 550 W 350 W 1100 W 700 W 90 dB SPL 89 dB SPL Screw / Banana date.
