If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center for help. Amplifier SYMPTOM Firmly plug in the power cord. No sound. Incorrect output cord connections. Connect the cords properly. If the problem persists, the cords may be defective. Appropriate input selector button is not pressed. Press the appropriate input selector button corresponding to the input source. The sound suddenly goes off. The protection circuit has activated because of short circuit etc. Turning the unit off and then on will reset the protection circuit. Only one side speaker outputs the sound. Incorrect setting of the BALANCE control Adjust it to the appropriate position. Incorrect cord connection. Connect the cord properly. If the problem persists, the cables may be defective. Incorrect cord connections. Firmly connect the audio plugs. If the problem persists, the cord may be defective. No connection from the turntable to the GND terminal. Make the GND connection between the turntable and this unit. The volume level is low while playing a record. The record is being played on a turntable with an MC cartridge. The player should be connected to the receiver through the MC head amplifier. The volume level cannot be increased, or sound is distorted. The power to the component connected to the REC OUT terminals of this unit is off. Turn the power to the component on. FM stereo reception is noisy. Because of the characteristics of FM stereo broadcasts, this is limited to cases where the transmitter is too far or the antenna input is poor. Check the antenna connections. Try using a multiple element FM antenna. There is distortion and clear reception cannot be obtained even with a good FM antenna. There is multipath interference. Adjust antenna placement to eliminate multipath interference. A desired station cannot be tuned in with Auto tuning. The station is too weak. Use Manual tuning mode. Use high quality directional FM antenna. A desired station cannot be tuned in with Auto tuning. Weak signal or loose antenna connections. Use Manual tuning mode. There are continuous crackling and hissing noises. Noises will result from ligtning, fluorescent lamps, motors, thermostats and other electrical equipment. Use an outdoor antenna and a ground wire. This will help somewhat but it is difficult to eliminate all noises. There are buzzing and whining noises (especially in the evening). A television set is being used nearby. Relocate this unit away from the TV. The remote control transmitter does not work. Direct sunlight or lighting (of an inverter type of flourescent lamp etc.) is striking the remote control sensor of the main unit. Change position of the main unit. The batteries of this remote control transmitter are too weak. Replace the batteries with new ones. The power to this unit is off. Turn the power to this unit on. FM AM Remote control transmitter Others REMEDY Power cord is not plugged in or is not completely inserted. Sound “hums”. 18 CAUSE The unit fails to turn on when the POWER switch is pressed. The sound is degraded when monitoring is performed by using the headphones connected to the compact disc player or cassette deck which are connected with this unit. Tighten the AM loop antenna connections and rotate it for best reception.  SPECIFICATIONS AUDIO SECTION Minimum RMS Output Power per Channel 8 ohms, 20 Hz to 20 kHz, 0.04% THD <RX-485> .....................................65W+65W <RX-385> [U.S.A. and Canada models].......45W+45W [Australia, U.K., Europe and General models]..........................40W+40W 6 ohms, 20 Hz to 20 kHz, 0.06% THD <RX-485> .....................................70W+70W <RX-385> [U.S.A. and Canada models].......48W+48W Dynamic Power per Channel (by IHF Dynamic Headroom measuring method) <RX-485> 8/6/4/2 ohms ....................95/115/135/150W <RX-385> [U.S.A., Canada and General models] 8/6/4/2 ohms ..........................69/78/90/98W [Australia, Europe and U.K. models] 8/6/4/2 ohms ..........................68/75/85/95W DIN Standard Output Power per Channel 4 ohms, 1 kHz, 0.7% THD [Europe model only] <RX-485> ..............................................85W <RX-385> ..............................................55W IEC Power <RX-485> 8 ohms, 1 kHz, 0.04% THD [Europe model only]..............................75W <RX-385> 8 ohms, 1 kHz, 0.04% THD [Europe model only]..............................50W Damping Factor 8 ohms, 20 Hz to 20 kHz ............................80 Input Sensitivity/Impedance PHONO MM ......................2.5 mV/47 k-ohms CD/TAPE/AUX ..................150 mV/47 k-ohms Maximum Input Signal (1 kHz, 0.01% THD) PHONO MM .........................................80 mV Headphone Jack Rated Output/Impedance 8 ohms, 20 Hz to 20 kHz, 0.04% THD Output Level <RX-485> ............................................0.46V <RX-385> ............................................0.45V Impedance <RX-485> ......................................390 ohms <RX-385> ......................................330 ohms Frequency Response (20 Hz to 20 kHz) CD/TAPE/AUX..................................0±0.5 dB RIAA Equalization Deviation PHONO MM .....................................0±0.5 dB Total Harmonic Distortion (20 Hz to 20 kHz) PHONO MM to REC OUT (1V) ............0.02% CD/TAPE/AUX to SP OUT <RX-485> (32.5W/8 ohms) ....................................0.02% <RX-385> (22.5W/8 ohms) ....................................0.02% Signal-to-Noise Ratio (IHF-A Network) PHONO MM (5 mV Input Shorted)........82 dB CD/TAPE/AUX (Input Shorted) ...........105 dB Residual Noise (IHF-A Network)............100 µV Channel Separation (Vol. –30 dB) PHONO MM (Input Shorted 1 kHz) .......60 dB CD/TAPE/AUX (Input 5.1 k-ohms Terminated 1 kHz)....60 dB Tone Control Characteristics BASS: Boost/cut .................±10 dB (50 Hz) (Turnover frequency) ...........................................(350 Hz) TREBLE: Boost/cut............±10 dB (20 kHz) (Turnover frequency) ......................................(3.5 kHz) Continuous Loudness Control ...............................................– 30 dB (1 kHz) (Level related equalization) FM SECTION Tuning Range [U.S.A., Canada and General models] ........................................87.5 to 107.9 MHz [Australia, Europe, U.K. and General models] ...........................87.5 to 108.0 MHz 50 dB Quieting Sensitivity (IHF, 75 ohms) [Except Europe model] Mono...............................1.55 µV (15.1 dBf) Stereo ................................21 µV (37.7 dBf) Usable Sensitivity (75 ohms) (30 dB S/N Quieting, 1 kHz, 100% mod.)
