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.WARNINGComponents having special characteristics are marked and must be replaced with parts having specification equal to thoseoriginally installed.RadioFans.CN 收音机爱 好者资料库AG-Stomp3SPECIFICATIONSDigital Section Full Digital Signal Processing Mic Simulator: 8 Types Feedback Reduction: 5-band Digital Effects Limiter Digital Chorus, Digital Delay Hall Reverb, Room Reverb, Plate Reverb External Controller Function (EXP Pedal/MIDI): 8 Controllers/Parameters Tuner Function (Chromatic, Auto)MIDI FunctionsReceive: Program Change (Program Change Table can be cre-ated), Control Change, Bulk InTransmit: Program Change, Control Change, Bulk Out, MergeOutGuitar Power Supply9V power can be supplied via a TRS phone cable to a guitarsbuilt-in pre-amplifier, etc. that consumes less than 10mA ofpower, and uses a monaural output.Controller/SwitchTop PanelPush Switch x17UP, DOWN, MANUAL, UTILITY, STORE, LIMITER, FEEDBACK REDUCTION 1-5, CHORUS, DELAY, HALL, ROOM,PLATE, SHIFTKnob x15MIC TYPE, BLEND, VOLUME, BASS, MIDDLE, TREBLE,PRESENCE, LIMITER LEVEL, FEEDBACK REDUCTIONFREQ, FEEDBACK REDUCTION DEPTH, CHORUSSPEED/DELAY TIME, CHORUS DEPTH/DELAY FEEDBACK, CHORUS LEVEL/DELAY LEVEL, REVERB LEVEL,OUTPUTFootswitch x41, 2, 3 BANKRear PanelSTAND-BY ON/OFF, MUTE, +9V SUPPLY ON/OFFDisplay7 Segment LED (3 digit) x1Push Switch LED x17Footswitch LED x4ConnectionsINPUT: Standard Stereo Phone JackOUTPUT L/MONO, R: Standard Stereo Phone Jack (TRS Balanced)PHONES: Standard Stereo Phone JackEXP.
