Quick Start - Fishman PREFIX STEREO BLENDER User Manual

At the heart of the pickup is a multi-layer stack of co-polymer strips. These strips sense motion
across the entire length of the saddle for unparalleled performance. Compared ceramic pickups
with individual elements, the Acoustic Matrix' "unitary" co-polymer design provides a more 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.

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). Conveniently shock-mounted to the underside of the preamp chassis, the microphone is strate-
gically isolated inside the instrument. For stage use, the Microphone's interior location affords
you unprecedented freedom of movement as well as minimal bleed through from other instru-
ments.

We recommend that you preset the system EQ to locate and eliminate microphone
feedback before you mix in the under-saddle pickup.
1. Set all controls as follows:
• Notch and Volume fully counter-clockwise
• All EQ sliders at center position
• Blend slider at full left position (A = microphone)
2. Slowly increase the volume and play the notes from the open low E, up to the
fourth fret G sharp until the instrument starts to rumble or howl with feedback on
one or more of these notes. Adjust the Notch control until this feedback is elimi-
nated (usually between one and two o'clock on the dial).
3. 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.
