Electric Acoustic GuitarOwner’s ManualPRECAUTIONSl Always set the guitar’s VOLUME control and the volume control on theamplifier to their minimum levels when connecting or disconnecting thecable.l The built-in preamplifier is automatically turned ON when a guitarcable is connected to the output jack. When not using the instrument,or when playing it without amplification, be sure to remove the guitarcable from the output jack so that the preamplifier power is turned OFF.Also, if the instrument is not going to be used for an extended period oftime, or when battery power is depleted, we recommend that the bat-teries be removed in order to avoid power consumption or leakage.l Even when the guitar cable is disconnected from the output jack, pow-er is turned ON when the TUNER switch is ON ( ). Always turn theTUNER switch OFF ( ) after using the tuner.This Yamaha electric-acoustic guitar incorporates a new pickup andelectronics system designed to capture and deliver a real acousticsound like that of an acoustic guitar recorded with a microphone.In order to make the most of the advanced features and performanceprovided by your guitar, please read this manual carefully before us-ing the instrument.BATTERY REPLACEMENTSPECIFICATIONSl System: System-62 l Pickup: Piezo-electric pickup (mounted inthe saddle section) l Preamplifier Controls: Vol., 3-Band EQ (HIGH,MID, LOW), TYPE (1/2/3), FOCUS/WIDE, RESONANCE, BLEND,A.F.R., TUNER l Output Jack: Combination end pin/power switchl Output Impedance: 1kΩ l Batteries: Size AA alkaline battery (LR6)x2 l Battery Life: Approx. 20 hours (Without tuner and using alkalinebatteries. May differ due to operating conditions.) l Tuner: Chromatictype (12 semi-tones), Calibration (A= 438 to 445Hz), Accuracy range+/– 3 cents l Accessories: Neck adjustment hex-wrench x1, Size AAalkaline battery x2, Sound hole cover x1USING THE TUNERq Press the TUNER switch ( ) to activate the tuner. (The lampslight.)w Tune the guitar string until the note name of the desired pitch appears in thedisplay.e The string is in tune when only the lamp lights in the center of thedisplay.Pitch is low g g g In Tune f f f Pitch is highUSING A.F.R. (Auto Feedback Reduction)If you experience problem feedback while performing, follow the A.F.R. set-ting instructions below to effectively control the feedback.q When feedback occurs, press the A.F.R switch after all sound other than thefeedback has muted.* The system may have a difficult time detecting the problem frequency if two or moresounds are present at the same time.w The system automatically detects the frequency causing the feedback andapplies a –12dB notch filter. The number of notch filter bands currently ap-plied is shown in the display.* The system can apply a maximum of 5 notch filter bands.* If the detected frequency is the same or very close to a frequency that is alreadybeing suppressed with a notch filter, the notch filter gain will be decreased an ad-ditional 6dB (–12dB g –18dB and –18dB g –24dB, two stages).* If all five notch filters are in use and another frequency is detected after the A.F.R.button is pressed, “ ” appears in the display and the new frequency cannot be set.* The system will not apply a notch filter if it cannot properly detect the problem fre-quency.e Hold the A.F.R switch until “ ” appears in the display to cancel all notchfilters. Or, switch off the power (unplug cable from output jack) to cancel allnotch filters.q VOL Control: Controls the volume.* Always set the volume to its minimum level when connecting or disconnecting thecable.w 3-Band Equalizer: Adjusts the LOW, MID, and HIGH frequency levels.e TUNER Switch: Switches the tuner ON ( )/OFF ( ).r Display: Displays tuner information and settings, and A. F. R. functions.t TYPE Switch: Selects the pickup’s mic simulation type (1: large dia-phragm condenser mic/ 2: small diaphragm condenser mic/ 3: ribbon mic).y FOCUS/WIDE Switch: Selects the setting for the simulated mic.FOCUS: This setting delivers a clear tone appropriate for use when play-ing with a band.WIDE: This setting delivers broad tone appropriate for solo use.u RESONANCE Control: Rotating to the right delivers more body tone,rotating to the left produces less. The knob’s central detent position is thestandard setting.i BLEND Control: Controls the mix level of signals received from the pick-up and the simulated mic. Rotate fully to the left for 100% pickup signaland fully to the right for 100% simulated mic signal.o A.F.R Switch: When feedback occurs, this function automatically detectsthe problem frequency and applies a filter to eliminate the feedback.Sound Hole Cover (supplied): Inserting the sound hole cover into thesound hole effectively reduces feedback.Battery HolderControl SectionOutput Jack(with power switch function)Pickup SectionNOMENCLATURE/CONTROL INSTRUCTIONSAs battery power becomes depleted, the triangular icons blink alternately( ) in the display, replace the batteries as soon as pos-sible.Release LeverBattery HolderAlkalinebattery x2q Press the release lever on the batterycase in the direction indicated by the ar-row in the illustration in order to unlockit, and then slide out the battery holder.w Remove the old batteries from the batteryholder, and insert the two new size AA al-kaline batteries. Make sure that the poleson the batteries are properly positioned asshown in the diagram inside of the holder.* Use alkaline batteries only.* Always change both batteries at the sametime. Do not mix new and old batteries, ordifferent type batteries (batteries made by dif-ferent manufacturers or batteries by the same manufacturer but of different types).Not doing so can result in fire, etc.* Never dismantle the batteries and never dispose batteries in fire.* Never touch any fluid that may leak from the battery. If the fluid should come in con-tact with the eyes, mouth, or skin, wash immediately with water and consult a doctor.e Slide the battery holder back into the battery case and press firmly so thatthe battery holder locks in place.r Press the TUNER switch again to switch the tuner OFF ( ). (Thelamps are off.)* It may take a few seconds before the tuner can detect pitches after being switchedON.* The note name and displays may have difficulty keeping up with irregularpitch changes. Gradually change the pitch and check when tuning.* The tuner may have a difficult time detecting notes rich with overtones or with veryshort sustain.* Sound output is muted when the tuner is in use.l Calibration (changing the reference pitch)The tuner’s reference pitch can be adjusted within a range of A = 438 to445Hz (set to 440Hz when the power is switched ON).q After switching the tuner ON, press the A.F.R switch. The last digit of thecurrent reference pitch is shown in the display.w Pres the A.F.R switch after the reference pitch is displayed to change thereference pitch in 1Hz increments.
