ACOUSTIC GUITAR SYSTEM. Please read these instructions care-

The PREFIX PLUS™ is an instrument-mounted pickup / preamp sys-
tem that offers total control of your amplified guitar sound.

THE PICKUP

The 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 PREAMP

The 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.
