It has been assumedthat basic service procedures inherent to the industry, and more specifically Yamaha Products, are already known and under-stood 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 per-sonal injury, destruction of expensive components and failure of the product to perform as specified. Forthese reasons, we advise all Yamaha product owners that all service required should be performed by anauthorized Yamaha Retailer or the appointed service representative.IMPORTANT :This presentation or sale of this manual to any individual or firm does not constitute authorization certifi-cation, recognition of any applicable technical capabilities, or establish a principal-agent relationship ofany form.The data provided is belived to be accurate and applicable to the unit(s) indicated on the cover. The research engineering, andservice departments of Yamaha are continually striving to improve Yamaha products. Modifications are, therefore, inevitableand changes in specification 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 bus in the unit (heavy gauge black wires connect tothis bus.)IMPORTANT :Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply powerto the unit.WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (Whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possiblyother 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 WHATSO EVER!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 before handlingfood.印部品、安全維持重要部品。交換場合、安全必指定部品使用。RadioFans.CN 收音机爱 好者资料库P1000S/P2500S/P3500S3SPECIFICATIONSP3500SP2500SPower Output Level (Rated Power)Power Bandwidth8 /STEREO4 /STEREO8 /BRIDGE 390 W x 2 590 W x 21180 W x 1 350 W x 2 450 W x 2 900 W x 11000 W x 22000 W x 1 275 W x 2 390 W x 2 780 W x 1 250 W x 2 310 W x 2 620 W x 1 650 W x 21300 W x 11 kHzTHD + N = 1%8 /STEREO4 /STEREO8 /BRIDGE 2 /STEREO4 /BRIDGEHalf Power 10 Hz 40 kHz (THD + N = 0.5 %)Total Harmonic Distortion (THD + N)4 8 /STEREO8 /BRIDGE0.1 %20 Hz 20 kHz, Half PowerFrequency ResponseRL = 8 , Po = 1 W0 dB, +0.5 dB, 1 dB f = 20 Hz 50 kHzIntermodulation distortion (IMD)4 8 /STEREO8 /BRIDGE32.1 dB30 k/balanced, 15 k/unbalancedPOWER switch (Push on/Push off)Two 31-step Volume control knobs (one per ch)MODE switch (STEREO/PARALLEL/BRIDGE)Two FILTER switches (SUBWOOFER/LOW CUT/OFF)Two fc knobs (25 to 150 Hz)YS Processing switch (ON/OFF)XLR-3-31 jacks (one per ch)1/4-inch balanced TRS phone jacks (one per ch)Speakon jacks (one per ch)5-way binding posts1/4-inch phone jacks (one per ch)x 1 (Green)x 1 (Red)x 1 (Red) (heatsink temp 85 C)x 2 (Red)x 2 (Green)x 1 (Yellow)POWER switch ON muting, DC detectionTemp. detection (heat sink temp 90C), VI limiter (RL 1 )Comp: THD 0.5 %Single variable-speed fan120 V, 60 Hz230 V, 50 Hz240 V, 50 Hz480 x 88 x 456 mmSecurity cover (with a hex wrench), Owners Manual102 dB100 dB60 Hz:7 kHz, 4:1, Half PowerChannel SeparationResidual Noise Vol. min.SN RatioDamping FactorSensitivity (Vol. max.)
