YST-SW011IMPORTANT NOTICEThis manual has been provided for the use of authorized YAMAHARetailers and their service personnel.It has been assumed that basic service procedures inherent to the industry,and more specifically YAMAHA Products, are already known andunderstood by the users, and have therefore not been restated.WARNING:Failure to follow appropriate service and safetyprocedures when servicing this product may result inpersonal injury, destruction of expensive components,and failure of the product to perform as specified. Forthese reasons, we advise all YAMAHA product ownersthat any service required should be performed by anauthorized YAMAHA Retailer or the appointed servicerepresentative.IMPORTANT:The presentation or sale of this manual to any individualor firm does not constitute authorization, certification orrecognition of any applicable technical capabilities, orestablish a principle-agent relationship of any form.The data provided is believed to be accurate and applicable to the unit(s)indicated on the cover. The research, engineering, and service departmentsof YAMAHA are continually striving to improve YAMAHA products.Modifications are, therefore, inevitable and specifications are subject tochange without notice or obligation to retrofit. Should any discrepancyappear to exist, 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 inthe unit (heavy gauge black wires connect to this buss).IMPORTANT:Turn the unit OFF during disassembly and partreplacement. Recheck all work before you apply powerto the unit.I CONTENTSTO SERVICE PERSONNEL . 2SPECIFICATIONS / 参考仕様 . 3INTERNAL VIEW . 4REAR PANELS . 56DISASSEMBLY PROCEDURES / 分解手順 . 78BLOCK DIAGRAM. 8PRINTED CIRCUIT BOARD . 9SCHEMATIC DIAGRAM . 10PARTS LIST. 1117 05.02100944P.O.Box 1, Hamamatsu, JapanSERVICE MANUALSUBWOOFER SYSTEMYST-SW011RadioFans.CN 收音机爱 好者资料库YST-SW0112YST-SW011WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLEI 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 ohmsshunted by 0.15F.“CAUTION”“F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 1.6A, 125V FUSE.”CAUTIONF1: REPLACE WITH SAME TYPE 1.6A, 125V FUSE.ATTENTIONF1: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 1.6A, 125V.WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and /or plastic(where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency(and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.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.About Lead Free Solder / 無鉛Side ASide BSMT REFLOW ProcessMI FLOW ProcessSolder Dip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。Among some types of lead free solder currently available,it is recommended to use one of the following types for therepair 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 solder isabout 30C to 40C (50F to 70F) higher than that of the leadsolder, be sure to use a soldering iron suitable to each solder.2. If lead solder must be used, be sure to remove lead free solderfrom each terminal section of the parts to be replaced andfrom the area around it completely before soldering, or makesure that the lead free solder and lead solder melt togetherfully.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。MAIN P.C.B.SIDE A / A 面-SIDE B / B 面Lead Free Solder / 無鉛RadioFans.CN 收音机爱 好者资料库YST-SW0113YST-SW011I SPECIFICATIONS / 参考仕様Type / 型式.Advanced Yamaha Active Servo TechnologyOutput Power / 出力 (100 Hz, 5 ohms, 10% T.H.D.). 50 WInput Sensitivity / 入力感度 (50 Hz, 50W / 5 ohms)INPUT (PJ). 50 mVDynamic Power / (5 ohms). 100 WInput Impedance / 入力INPUT (PJ) . 12 k-ohmsFrequency Response / 再生周波数帯域.30 Hz to 200 HzDriver / (Magnetic Shielding Type). 8 (20 cm) coneInput Section / 入力部INPUT .
