If equipment is damaged inany way or unexpected trouble occurs during playback, unplug thesystem from its outlet and call a serviceman for help.Protection circuitrySB-FS50 / SB-PC50These units incorporate protection circuitry to protect them from dam-age caused by excessive input or abnormal signals; when excessinput is detected, input is automatically interrupted.If sound is interrupted...1.Reduce the volume of the receiver (or amplifier).2.Check the sound source and connections for any problems.If there is no problem, the protection circuitry will reset in a fewminutes.After the protection circuit is reset...Take care not to increase the receiver’s volume too high.Excessive inputYou can damage your speakers and shorten their usefullife if you play sound at high levels over extended periods.Reduce the volume in the following cases to avoid damage :•When playing distorted sound.•When the speakers are receiving howling from a microphone orrecord player, noise from FM broadcasts, or continuous signals froman oscillator, test disc, or electronic instrument.•When adjusting the sound quality.•When turning the amplifier on or off.Other notesIf irregular coloring occurs on your television :These speakers are designed to be used close to a television, but thepicture may be affected with some televisions and set-up combina-tions.If this occurs, turn the television off for about 30 minutes.The television’s demagnetizing function should correct the problem.If it persists, move the speakers further away from the television.You cannot remove the speaker net.Keep magnetized items away.Magnetized cards, bank cards, commuter passes, etc., can be dam-aged if allowed too near speaker magnets. Clocks may also be af-fected.Avoid locations such as described below :•In direct sunlight•Near heating appliances or other sources of heat•Where the humidity is highMaintenanceClean these units with a soft, clean, dry cloth.Clean regularly to maintain the polished surface.•Never use alcohol, paint thinner, or benzine to clean these units.•Before using chemically treated cloth, read the instructions that camewith the cloth carefully.SpecificationsSB-FS50Type 2 way 3 speaker system Closed typeSpeaker (s) Woofer: 8 cm cone type x 2Tweeter: 2.5 cm semi-dome type x 1Impedance 6 ΩInput power 200 W (Music), 100 W (DIN)Sound pressure level 81 dB/W (1.0 m)Crossover frequency 3 kHzFrequency range 140 Hz – 50 kHz (at –16 dB)180 Hz – 45 kHz (at –10 dB)Dimensions (W x H x D) 240 x 1108 x 211 mmMass 5.5 kgSB-PC50Type 3 way 5 speaker system Bass-reflex typeSpeaker (s) Woofer: 5 cm cone type x 4Tweeter: 2.5 cm semi-dome type x 1Impedance 6 ΩInput power 200 W (Music), 100 W (DIN)Sound pressure level 82 dB/W (1.0 m)Crossover frequency 3.5 kHz, 4.5 kHzFrequency range 130 Hz – 50 kHz (at –16 dB)150 Hz – 45 kHz (at –10 dB)Dimensions (W x H x D) 430 x 64 x 100 mmMass 1.8 kgSB-WA55SPEAKER SECTIONType 1 way 1 speaker system Bass-reflex typeSpeaker (s) Woofer: 17 cm cone type x 1Impedance 6 ΩInput power 200 W (Music), 100 W (DIN)Sound pressure level 80 dB/W (1.0 m)Frequency range (with amp) 32 – 300 Hz (at –16 dB)38 – 240 Hz (at –10 dB)AMPLIFIER SECTIONOutput power 100 W (6 Ω) (THD 0.9%)Input sensitivity / Input Impedance 300 mV/33 kΩ (RCA jack)Phase switching NORMAL/REVERSELow pass filter 50 – 200 Hz VariableGENERALPower supply AC 230 – 240 V, 50 HzPower consumption 168 WDimensions (W x H x D) 162 x 457 x 420 mmMass 10.8 kgSpecifications are subject to change without notice.Mass and dimensions are approximate.
