Forthese reasons, we advise all YAMAHA product owners that any service required should be performed byan authorized YAMAHA Retailer or the appointed service representative.IMPORTANT:The presentation or sale of this manual to any individual or firm does not constitute authorization, certifica-tion or recognition of any applicable technical capabilities, or establish a principle-agent relationship ofany form.The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering,and service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore,inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear toexist, please contact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity your body may haveaccumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to thisbuss).IMPORTANT:Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power tothe unit.RDX-E600RX-E600、NX-E400及DVD-E600構成。RX-E600及NX-E400用。DVD-E600下記参照。DVD-E600 100924 04.09RadioFans.CN 收音机爱 好者资料库RX-E600/NX-E4002RX-E600/NX-E400I TO SERVICE PERSONNEL1. Critical Components InformationComponents having special characteristics are marked sand must be replaced with parts having specifications equalto those originally installed.2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits.GMeter impedance should be equivalent to 1500 ohmshunted by 0.15F.WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLEWARNING: CHEMICAL CONTENT NOTICE!The solder used in the manufacturing process except soldering of the P.C.B. assy contains LEAD. In addition, otherelectrical/electronic and /or plastic (where applicable) components may also contain traces of chemicals found by theCalifornia Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductiveharm.DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-SON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or exposeeyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands beforehandling food.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.“CAUTION”“F232: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 3.15A,125V FUSE.”CAUTIONF232: REPLACE WITH SAME TYPE 3.15A, 125V FUSE.ATTENTIONF232: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 3.15A, 125V.About Lead Free Solder / 無鉛The P.C.B.s installed in this unit are soldered using thefollowing solder.本機搭載基板付使用下記通。Among some types of lead free solder currently available,it is recommended to use one of the following types forthe repair work. Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth)Caution:1. As the melting point temperature of the lead free solderis about 30C to 40C (50F to 70F) higher than that ofthe lead solder, be sure to use a soldering iron suitableto each solder.2. If lead solder must be used, be sure to remove leadfree solder from each terminal section of the parts tobe replaced and from the area around it completelybefore soldering, or make sure that the lead free solderand lead solder melt together fully.無鉛種類、修理時下記無鉛使用推奨。Sn+Ag+Cu （錫+銀+銅）Sn+Cu （錫+銅）Sn+Zn+Bi （錫+亜鉛+）注意： 無鉛融点温度通常鉛入比3040程度高、合使用。 鉛入使得場合、交換部品端子部周辺部無鉛取除、無鉛鉛入十分溶状態付。MAIN P.C.BOPERATION P.C.BSIDE A / A面-SIDE B / B面Lead Free Solder / 無鉛Lead Free Solder / 無鉛Side ASide BSMT REFLOW ProcessMI FLOW ProcessSolder DipRadioFans.CN 收音机爱 好者资料库RX-E600/NX-E400RX-E600/NX-E4003B, G, E modelsU, C, R, K, A, L, J modelsI FRONT PANELSI REAR PANELSR modelU, C modelsA modelK modelG, E modelsB modelRX-E600/NX-E4004RX-E600/NX-E400I AUDIO SECTION / 部Minimum RMS Output Power Per Channel / 定格出力20Hz to 20kHz, 0.1% THD, 6 ohms . . . . . . . . . . 40W + 40W1kHz, 0.1% THD, 6 ohms . . . . . . . . . . . . . . . . . . 55W + 55WMaximum Power Per Channel / 実用最大出力 (EIAJ)1kHz, 10% THD, 6 ohms (R, J models) . . . . . . . 65W + 65WDynamic Power Per Channel / (IHF)6 ohms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 60W + 60W4 ohms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 75W + 75W2 ohms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100W + 100WDIN Standard Output Power Per Channel / DIN1kHz, 0.7% THD, 4 ohms (G, E models) . . . . . . 60W + 60WDynamic Headroom / (6 ohms)U, C, models . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.76dBIEC Power Per Channel / IEC1kHz, 0.1% THD, 6 ohms (G, E models) . . . . . . 55W + 55WPower Band Width / 幅0.1% THD, 30W/6 ohms . . . . . . . . . . . . . . . . 10Hz to 50kHzDamping Factor / 20Hz to 20kHz, 6 ohms . . . . . . . . . . . . . . . . . . . .60 or moreInput Sensitivity/Impedance （入力感度/入力）DVD, etc . . . . . . . . . . . . . . . . . . . . . . . . . . 150mV/47k-ohmsMaximum Input Signal Level / 最大許容入力 (1kHz, 0.5% THD)DVD, etc . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.0VOutput Level/Impedance （出力電圧/出力）REC OUT (MD, TAPE) . . . . . . . . . . . . . . . 150mV/1.2k-ohmsSUB WOOFER (50Hz) . . . . . . . . . . . . . . . . . 2.0V/680-ohmsHeadphone Jack Rated Output/Impedance （出力/出力）DVD, etc 1kHz, 150mV, 8 ohms . . . . . . . . . 0.43V/330 ohmsFrequency Response / 周波数特性 (20Hz to 20kHz)DVD, etc . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 00.5dBTotal Harmonic Distortion / 全高調波歪率 (20Hz to 20kHz)DVD, etc to SP OUT (20W/6 ohms) . . . . . . . . . . . . . . 0.04%Signal-to-Noise Ratio / 信号対雑音比 (IHF-A-Network)DVD, etc, Input Shorted (150mV) . . . . . . . . . . . . . . . . . 93dB(250mV) . . . . . . . . . . . . . . . . . 98dBResidual Noise / 残留 (IHF-A-Network)SP OUT . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100VChannel Separation / (Vol. 30dB)DVD, etc, Input 5.1k-ohms Shorted, 1kHz/10kHz 60dB/45dBTone Control Characteristics / 特性BASS: Boost/cut . . . . . . . . . . . . . . . . . . . . 10dB (50Hz)Turnover Frequency . . . . . . . . . . . . . . . . . 350HzTREBLE : Boost/cut . . . . . . . . . . . . . . . . . . . 10dB (20kHz)Turnover Frequency . . . . . . . . . . . . . . . . . 3.5kHzFilter Characteristics / 特性SUB WOOFER (L.P.F.) . . . . . . . . . . . . . fc = 100Hz, 6dB/oct.I SPECIFICATIONS / 参考仕様I AM SECTION / AM部Tuning Range / 受信周波数範囲U, C models . . . . . . . . . . . . . . . . . . . . . . . . .530 to 1710kHzR, L models . . . . . . . . . . . . . . . 530 to 1710/531 to 1611kHzA, B, G, E, J models . . . . . . . . . . . . . . . . . . .531 to 1611kHzUsable Sensitivity / 実用感度 . . . . . . . . . . . . . . . . . . 300V/mAntenna / 入力 . . . . . . . . . . . . . . . . . . .
