SERVICE MANUALAV RECEIVER/AV AMPLIFIERRX-Z1/DSP-AZ1100798IMPORTANT NOTICEThis manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already known and understoodby the users, and have therefore not been restated.WARNING:Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction ofexpensive components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product ownersthat any service required should be performed by an 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, certification or recognition of anyapplicable technical capabilities, or establish 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 departments ofYAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to changewithout notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by groundingyourself to the ground buss in the unit (heavy gauge black wires connect to this buss).IMPORTANT:Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.P.O.Box 1, Hamamatsu, JapanI CONTENTSTO SERVICE PERSONNEL . 1IMPEDANCE SELECTOR . 1FRONT PANELS. 2REAR PANELS . 24REMOTE CONTROL. 5SPECIFICATIONS. 69INTERNAL VIEW . 10DISASSEMBLY PROCEDURES / 分解手順 . 1113SELF DIAGNOSIS FUNCTION (DIAG) /自己診断機能（）. 1442AMP ADJUSTMENT / 調整. 43DISPLAY DATA . 4445IC DATA . 4665BLOCK DIAGRAM. 6669PRINTED CIRCUIT BOARD . 7099PIN CONNECTION DIAGRAM . 100101SCHEMATIC DIAGRAM . 102111PARTS LIST. 112173REMOTE CONTROL. 174177UPDATING FIRMWARE /更新方法. 178184RX-Z1/DSP-AZ1DSP-AX1UG、併記。 . 4P.C.B.

In addition, other electrical/electronic and/or plastic (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (andpossibly 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.I 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 ohm shuntedby 0.15F.I IMPEDANCE SELECTORIMPEDANCE SELECTORWARNING:Do not change the IMPEDANCE SELECTOR switch setting while the power to this unit is on,
