The NX-210P and NX-C210 loudspeakers are not field serviceable and must be replaced as complete units. IMPORTANT NOTICE This 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 understood by 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 of expensive components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product owners that 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 any applicable 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 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 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 grounding yourself 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.

Components having special characteristics are marked Z and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only). When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohm shunted by 0.15F. AC LEAKAGE TESTER OR EQUIVALENT EQUIPMENT UNDER TEST INSULATING TABLE WALL OUTLET 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 REASON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. 1 I SW-P201 REAR PANELS GLeakage current must not exceed 0.5mA. GBe sure to test for leakage with the AC plug in both polarities.

Removal of Front Grille The front grille is fixed to the cabinet with dowels at 6 locations. * As a screwdriver (for slotted head screw) is used for removal, use special care not to cause damage to the cabinet. a. Using the screwdriver inserted in the gap between the front grille and the cabinet (bottom side first), push up the front grille. b. Remove the front grille by lifting it up. When installing the Front Grille, apply quick-drying bond to the dowels and then fit them into dowel holes for secure installation. (The Front Grille will come off easily if its dowels are fitted into dowel holes only.) 2. Removal of Rear Panel Remove 14 screws ( q ) in Fig. 2. *Arrow marks are printed to identify the screws to be re- moved. q Fig. 2 Fig. 1 *When assembling the Rear Panel, check to ensure that the packing is not damaged so as to prevent air leakage from occurring. 4 NS-P210 NS-P210 ISW-P201 BLOCK DIAGRAM IC1A IC1B IC2A AUTO POWER SW1 AUTO POWER ON/OFF CIRCUIT VR1 VOLUME L.P.F. 6dB/oct H.P.F. 12dB/oct L.P.F. 12dB/oct 3 61 5 76 8 7 IC2B IC4 IC5 A.N.I.C LIMITER RY1 RY2 4 2 2 IC7, 8 Q12 D15, 16, 18 Q4Q7 D10, 11, 19, 20 1 10 D13 D4 D14 D2 D1 Q10 D5 B +B 9 8 3 2 0.1 PROTECTION H/L OFF VCC PWR R65 C51 TIMER IC6 MUSIC SENSOR IC3 8 4 6 3 7 Q11 +15 +B B 15 VCC REGULATOR REGULATOR Q1, Q2 Q3 POWER SUPPLY D3 Q8, D8 Q9, D9 F1 POWER SW L R + + INPUT 1 SPEAKER L R INPUT 2 L R + + OUTPUT + POWER AMP 5 ABCDE 1 2 3 4 5 6 7 NS-P210 I SW-P201 PRINTED CIRCUIT BOARD (Component side) WH BL RE TO : AMP (B) WH RE TO : SPEAKER AMP P.
