Fishman Prefix Plus 钢琴电子系统用户指南说明书
This fine instrument is equipped with a FISHMAN PREFIX PLUS™ACOUSTIC GUITAR SYSTEM.Please read these instructions care-fully.If you have any questions or problems, please call our CUS-TOMER SERVICE LINE at (978) 988-9665.The PREFIX PLUS™ is an instrument-mounted pickup / preamp sys-tem that offers total control of your amplified guitar sound.THE PICKUPThe PREFIX PLUS™ ACOUSTIC GUITAR SYSTEM includes the FISH-MAN ACOUSTIC MATRIX pickup;made with a unique co- polymer sensing material available exclusively from Fishman.This technology is not available from any other manufacturer.The sensing material exhibits a sensitivity and dynamic range that far surpasses all other known sensing materials.The ACOUSTIC MATRIX transducer is a fully EMI shielded, multi-layer sandwich of co-polymer strips that run the length of the pickup.This design allows the pickup to sense the motion of the entire saddle length, providing superb string to string balance, as well as sensitivity to both the strings and top of the instrument. THE PREAMPThe PREFIX PLUS™ preamp module incorporates a unique "flip-top" battery compartment for easy access. A variable NOTCH filter, shelv-ing BASS & TREBLE , semi-parametric CONTOUR, and BRILLIANCE controls are included for precise tone shaping and fighting feedback. There is also a PHASE reversal switch and a low battery indicator. The PREFIX PLUS™ can be plugged into any instrument-level audio input with excellent results.2PREAMP FUNCTIONSBATTERY COMPARTMENTPull the small tab at the top of the PREFIX PLUS™ toward you.The body of the preamp will swing out, revealing the BATTERY COMPARTMENT.Insert a fresh 9V alkaline battery.cable from the endpin jack when the unit is not being used.NOTE:Plug an instrument cable into the endpin jack before you plug into the sound equipment.Doing so will prevent loudspeaker damage.BATTERY LOW INDICATORWhen plugging into the endpin jack, the LOW BATTERY light will flash momentarily, indi-cating that the power is on.When the LOW BATTERY light stays on, it is time to change the battery.CONTROLSNOTCH FILTERThis is a fixed level, variable-frequency filter for eliminating feedback or unwanted reso-nance.The affected frequency is variable from 40 to 500 Hz.The NOTCH FILTER is effectively off in the full counter-clockwise position.3VOLUME CONTROLControls the overall gain of the PREFIX PLUS™.Goes from very quiet to very loud. BASS CONTROLThis is a boost/cut shelving tone control.The center detent yields a flat response. CONTOURThis is a Wide-range semi-parametric filter.It is used to selectively shape the instru-ment's tone.The CONTOUR Level slider controls the amount of boost or cut applied to the selected Contour FREQUENCY.The center detent yields a flat response.The Contour FREQUENCY slider determines the frequency band that is boosted or cut by the CONTOUR LEVEL control.The frequency is variable from 250 to 10 kHz. TREBLE CONTROLThis is a boost/cut shelving tone control.The center detent yields a flat response. BRILLIANCE CONTROLThis is a resonant style boost/cut filter.When boosted, the BRILLIANCE control can add presence to your sound or brighten up dead strings.PHASE SWITCHThe PHASE switch compensates for acoustic phase differences that often occur between instrument and speaker.It can be used as a tone filter at low volume levels or a feedback filter at high levels.The PHASE switch can correct any electrical phase difference between the PREFIX™ system and an outboard instrument microphone.Flip the PHASE switch several times and use your ear to find the optimum setting.The best position for the PHASE switch may change, depending on the sound system and/or venue acoustics. 4SUGGESTED EQ SETTINGSMID CUTYou can scoop out harsh midrange by setting the FREQUENCY slider slightly above center with the CONTOUR Level cut to taste below the center detent. You can alsocut midrange byboosting theBASS and TRE-BLE sliders torealize an"implied" mid-cut at 800 Hz.5FINGERSTYLEThis setting will add fullness to the bass and definition to the treble. 6CUT THROUGHFor cutting through a live band mix at high volumes.7WHAT IS PHASE?Phase is the relationship between two signals or soundwaves originating from the same instrument.For our purposes, phase relationships are expressed as being either "in phase" or "out of phase".In phase tends to enhance, while out of phase tends to sup-press the natural characteristics and acoustic tendencies of an instrument.A simple way to determine the quality of phase (in or out) of two sounds is to com-pare phase switch settings at low volumes.is when the wave-yourOUT OF PHASEOut of phase is when theinating from the same instru-upper peak of one waveoccurs at the same moment intime as the lower peak of theother.Out of phase is likelooking at yourself in a livevideo monitor;the image yousee is similar, but the per-spective is shifted.When you move to the right, the image appears to move to your left.Continued ...8WHAT IS THE PHASE SWITCH FOR?The phase switch is useful for two reasons:1.Due to the interactive and changing nature of phase, acoustic amplification depends on maintaining optimum phase relationships between amplified instruments, sound systems and venues.2.Since an industry standard for polarity has not been established for all sound equipment, the phase switch can compensate for any unintentional differences that might occur between instrument and sound system. APPLICATIONSIn any situation where the instrument faces a loudspeaker, there will be an inter-active phase relationship between the two.This usually occurs with stage amps, side fill and floor monitors at close distances.• LOW VOLUME AMPLIFICATIONAt low volumes, when an instrument and speaker are at similar levels and are in phase, the sound is full and solid, with the lower frequencies emphasized. When a mic'ed instrument and speaker are out of phase at low levels, the bass frequencies cancel out to some extent.The resulting sound is somewhat unnat-ural and unbalanced compared to in phase.• HIGH VOLUME LEVELSAt high volume levels, when an instrument and speaker are in phase, the sound pressure from the speaker will excite the instrument's sound chamber, creating a feedback loop at the instrument's lowest octave.This "cavity resonance" feed-back can be dealt with by putting the instrument and speaker out of phase or by adding equalization.ING THE PHASE SWITCH TO REDUCE FEEDBACK.Inverting the PHASE switch will put the instrument and speaker out of phase with each other, cancelling the low frequency feedback.If you move from your position on stage more than a few feet, you may have to invert the PHASE switch again to maintain an out of phase relationship between the mic'ed instrument and speaker.Continued ...9Here's why:A typical guitar has a cavity resonance of about 100 Hz.This is the frequency that generally feeds back when the guitar and speaker are in phase.100 Hz has a wavelength of about 11 feet.Phase inverts 180° for every 1/2 a frequency's wavelength.In this case, 1/2 the wavelength is about 5 1/2 feet.If you set your PHASE switch to eliminate cavity resonance (out of phase) and then move 5 1/2 feet towards or away from the speaker, you will effectively put the mic'ed guitar/speaker relationship at 100 Hz back in phase;in the line of fire for low frequency feedback.The PHASE switch on the ONBOARD BLENDER™ in effect electronically "moves" your instrument's position relative to the speaker by inverting the phase 180° every time you flip it.ING THE NOTCH FILTER TO REDUCE FEEDBACKNotching out instrument cavity resonance will eliminate the low frequency feed-back problem completely.The advantages to using notching equalization are:• The physical distance from the speaker will no longer be a factor for potential low frequency feedback.• The mic'ed instrument/speaker can remain in phase, maintaining a more nat-ural and balanced response.10SPECIFICATIONSNominal Input Level:-20 dBVInput Overload:(20 Hz - 20 kHz)-2 dBVInput Impedance:20 M OhmsOutput Impedance:Less than 3.5 k OhmsNominal Output Level:-12 dBVTHD:Less than .04 %, -20 dBV inputSignal to Noise Ratio:77 dB(A weighted referred to nominal-20 dBV input)Current Drain:Less than 3.5 mAPower Supply:9V Alkaline battery(estimated 160 hours continuous use with lowbattery indicator at 6.5V)Notch Filter Range:40Hz - 500 Hz (-15 dB)Bass Control Range:± 12 dB at 60 Hz± 3 dB at 350 HzTreble Control Range:± 12 dB at 10 kHz± 3 dB at 2.4 kHzContour Control Range:± 12dB(adjustable from 250 Hz to 10 kHz) Q = 0.5 Brilliance Control Range:± 9 dB at 10 kHzAll specifications subject to change without notice.11。

Enjoy the best of both worlds — a new-generation digital harpsichord with authentic sound and touch, excellent playability, and soul-stirring expression.■ Beautiful designAble to fit beautifully into a small space, the exquisite compact design is modeled on a small rectangularharpsichord known as the virginal. Picture board can be installed on the inside of the keyboard lid, and the side panels can be replaced with reproduction stained glass. Customization is available to match anyinterior so you can create the look you desire.■ Sensitive keyboard touchA newly developed special keyboard authentically reproduces the plucking sensation of a harpsichordkey when pressed. All of the characteristics of the harpsichord key action have been captured, includingthe length and form of the black keys, the depth of the key press, and even the distinctive noise thatcomes when a key is released.■ Rich timbreKnown as “Cembalo” in German and Italian and “Clavecin” in French, the harpsichord comes in various shapes and sizes. Two different types, Frenchand Flemish, of harpsichord sounds are built into the C-30. You can togglebetween them with the touch of a switch. For each sound, four buttons areavailable: 8-foot I (back), 8-foot II (front), 4-foot (octave higher), and lute (buffmute). You play them individually or layer them.In pursuit of the perfect harpsichord, Roland has equipped the C-30 with“Dynamic Harpsichord” sounds, which can be played with dynamics (velocitysensitivity) and a damper pedal. In addition, the sounds of the early fortepianoand a compact pipe organ have been included.Example of a French harpsichordMade 1765 by F .
