User manual FISHMAN PREFIX PREMIUM BLEND

[. . . ] Adjust the Notch control until this feedback is eliminated (usually between one and two o'clock on the dial). Increase the volume some more and play (on the low E string) the fifth fret A and above. Flip the phase switch to the position that eliminates feedback in this region. Slowly increase the Volume again, until you start to hear a high squeal. [. . . ] The Premium Blend's preamp module incorporates a unique flip-top battery compartment for easy access. Traditional shelving-style bass & treble, plus a semi-parametric "Contour" EQ are included so you can shape your guitar's tone exactly to taste. With the flick of a switch, you can choose between stereo or mono signal paths for the system's pickup and microphone. To complete the package, we include a phase switch and an adjustable notch filter, both essential for fighting feedback. Endpin Jack When you plug into the endpin jack, the Prefix Premium BlendTM switches on. To conserve the battery, remove the instrument cable from the endpin jack when the system is not being used. It is a good idea to turn down your amp or mixer input before you plug into the endpin jack. Battery Low LED Plug into the endpin jack and the Low Battery light will flash momentarily, indicating that the power is on. When the Low Battery light stays on, it is time to change the battery. THE PICKUP The system's under-saddle pickup is the industry standard Fishman Acoustic MatrixTM. It is made with our proprietary co-polymer sensing material which reproduces your acoustic guitar sound with a sensitivity and dynamic range that surpasses all other pickups. At the heart of the pickup is a multi-layer stack of co-polymer strips that sense motion across the entire length of the saddle for unparalleled performance. The Acoustic Matrix's "unitary" co-polymer design provides a natural and balanced response, with sensitivity to both the strings and the soundboard. The transducer is fully enclosed in a shielded foil wrap for quiet performance and total EMI noise rejection. CONTROLS Tuner Depress the tuner button to turn the circuit on and off. This digital chromatic tuner accommodates all standard and alternate tunings. For your convenience, the tuner button also acts as a mute switch for the guitar when you are plugged in. The tuner circuit devours battery power, so turn it off when you finish tuning. It will automatically shut down after about 30 seconds at idle to conserve battery power. The "in tune" indicator will flash several times before tuner shuts down. Note that the tuner is calibrated to A = 440. THE MICROPHONE This quality electret-condenser microphone will provide very high level sound reproduction before feedback when used in conjunction with the unit's Phase, Notch and Contour EQ (see pages 7-8). [. . . ] Midbass feedback generally occurs when you play bass notes above the fourth fret G# on the low E string. Bass A Boost here will add depth and weight to the sound the instrument. The Frequency slider lets you tune in on the specific range of sounds that you can boost/cut with the Contour (level) slider. The Contour control affects only the pickup and microphone signals at the tip output. With the Contour EQ you can boost or cut a wide range of frequencies, from gutsy low midrange (250 Hz) to brilliant high treble (10 kHz). [. . . ]
