User manual FENDER PREFIX PRO BLEND

[. . . ] You may plug the PREFIXTM PRO BLEND into any instrument-level audio input. THE PICKUP The included Acoustic MatrixTM pickup is made with a proprietary co-polymer sensing material, available exclusively from Fishman. Unlike so called "piezo-film" pickups, our unique copolymer formula is not available from any other manufacturer. Sound-wise, the Acoustic MatrixTM exhibits a sensitivity and dynamic range that far surpasses all other known pickups. [. . . ] 5. Clip / Battery Low LED This light has three distinct functions: 1. Power Up Indicator The Clip/Batt Low LED will flash momentarily when you first turn on the preamp. Some people ask us why this light doesn't stay on, like a conventional pilot light. We feel a steadily lit LED devours too many precious hours of battery life. We prefer instead to conserve the battery with a quick flash of the LED to indicate that the preamp is powered up. Clip Indicator If the LED flashes while you are playing, you are driving the preamp into distortion. This indicator may also flash as you approach the end of the battery's useful life. Low Battery Warning When the Clip/Low Batt LED lights steadily, it is time to change the battery. 6. 7. Double check the PHASE switch position until you find the clearest, feedback free response. Play your guitar as loud as you want. . Volume Affects both microphone and pickup levels. Set this as high as possible (without distorting your amp or mixer) for the cleanest signal. 3 4 P REFIX TM P RO B LEND F ISHMAN P REFIX TM S ERIES Notch and Phase These controls work hand in hand to eliminate low frequency feedback. When you set them properly, you can play your instrument as loud as you like, without feedback. For best results, tune the Notch filter first. SUGGESTED EQ SETTINGS Notch Use the Notch to scoop out the lowest range of feedback, which usually starts at the open low E string and continues up to about the forth fret G# on the same string. This "cavity resonance" feedback can usually be eliminated by setting the Notch control between 12:00 and 2:00 on the dial. You may need to initially coax out low frequency feedback by raising your volume, flipping the phase switch and moving closer to your speakers. Note that in the fully counter-clockwise position, the Notch is effectively off. ANTI-FEEDBACK Refer to page 3. Phase Switch Use the phase switch to control the upper range of low frequency feedback, sometimes call "top resonance". This feedback usually starts at the fifth fret A on the low E string and continues up to about the twelfth fret E on the same string. Flip the Phase switch back and forth until you find the position that subdues this range of feedback. Note: If, after setting the phase switch, you move your position a few feet, be prepared to flip the switch again to keep feedback at bay. Bass A boost/cut shelving tone control. In the center position the bass control does not affect the circuit. Contour EQ With this you can boost or cut a wide range of frequencies from gutsy low midrange (250 Hz) to squeaky-clean highs (10 kHz).
