manual abstract
This is especially true on amplifiers having an output power rating higher than that of the speaker system. Even if the amplifier to be used has an output power rating lower than that of the speaker system, the amplifier output may become distorted. This "clipping" distortion creates an excessive input level which can damage the speaker system. This type of distortion also occurs if the input signal to the amplifier is too large. Bass and treble controls also raise the level of the input signal to the speaker system so care should be taken to adjust the volume to a proper level. The volume level of the amplifier should be reduced if the following signals are to be applied to the speaker system: interstation noise of the FM radio band; output from a tape deck during rewind or fast forward; acoustic feedback from a microphone or musical instrument; electrical noise from the connection or disconnection of a phono cartridge, or phono / RCA cables. Speaker components protection This unit incorporates protection circuitry that automatically reduces the tweeter level when a safe overall input level has been exceeded. When the protection circuit is activated, the sound from the tweeter and midrange will be interrupted. If the sound is interrupted, do not operate the system continuously. The woofer is not affected by the protection circuit, therefore; sound will be heard from the woofer. Proceed as follows: 1. Reduce the volume setting of the amplifier. 2. Check whether or not there is any abnormal condition of the equipment used as the sound source, or of the connections. 3. If there is no abnormal condition, the protection circuitry will be automatically reset in a few minutes. After the protection circuit is reset... Do not increase the amplifier's level too high. Maintenance Although the enclosure and the speaker units of this speaker system are made of carefully selected materials and have been produced using the finest manufacturing techniques, sudden changes in surrounding temperature and/or humidity should be avoided. Keep this unit away from sources of heat, high humidity and direct sunlight. • The speaker system should not be placed near a TV. The speaker magnet may cause a disturbance in the TV picture. If the enclosure becomes dirty, use a soft, dry cloth to wipe it clean. If the dirt is excessive, soak a soft cloth in a weak solution of soap and water, wring it thoroughly before use. A soft dry cloth should then be used to wipe it dry. • Never use alcohol, paint thinner, benzine or other volatile chemicals to clean this unit because they may damage the finish, causing it to lose its luster. Also never use a wet or chemically-impregnated cloth. Specifications Note: Specifications are subject to change without notice. Weight and dimensions are approximate.
