U SER’ S G UIDE
WARNING!
WE STRONGLY RECOMMEND THAT YOU FAMILIARIZE YOURSELF WITH THE
PREAMP CONTROLS BEFORE YOU ATTEMPT TO PERFORM WITH THE ONBOARD
BLENDER. FAILURE TO DO SO COULD RESULT IN WAVES OF EAR-SPLITTING
FEEDBACK AT HIGH LEVELS. (see Quick Start on page 3.)
Congratulations! With your new Fishman Prefix™ProBlend we are pleased to offer a total
onboard amplification system in a very small and unobtrusive package. This is a simple yet
sophisticated system, so please take a few minutes to familiarize yourself with the control lay-
out and go over the Quick Start instructions on the next page. If you have any questions
please contact our Customer Service Department at 978.988.9665 or tech@fishman.com
The Prefix™ProBlend is an acoustic guitar system that combines the sounds from a Fishman
Acoustic Matrix™ pickup and a miniature electret condenser microphone. The microphone,
shock-mounted on the underside of the preamp chassis, captures the elusive natural ambi-
ence and resonance of the guitar's sound chamber. The Acoustic Matrix™ pickup delivers a
clear, articulate sound with emphasis on string definition and attack. When combined, the two
signals produce a powerful and cohesive acoustic guitar tone that is much greater than the
sound of either microphone or pickup alone.
Downsized to fit even the thinnest of guitars, the second generation Prefix™ProBlend preamp
occupies 1/3 less surface area on the side of a guitar than our standard Prefix™ series. The
preamp module incorporates a space saving "flip-top" battery compartment for easy access.
Levels are set by the master VOLUME and BLEND controls. BASS & TREBLE controls, a
semi-parametric CONTOUR control, a NOTCH filter and PHASE switch are included for pre-
cise tone shaping and feedback control. You may plug the PREFIX™ PRO BLEND into any
instrument-level audio input.
THE PICKUP
The included Acoustic Matrix™ pickup is made with a proprietary co-polymer sensing mater-
ial, available exclusively from Fishman. Unlike so called "piezo-film" pickups, our unique co-
polymer formula is not available from any other manufacturer. Sound-wise, the Acoustic
Matrix™ exhibits a sensitivity and dynamic range that far surpasses all other known pickups.
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 the soundboard of the instrument.
THE MICROPHONE
The microphone, in conjunction with PHASE, NOTCH and CONTOUR controls (see page 6),
will provide very high level sound reproduction before feedback. Conveniently shock-mounted
to the back of the preamp case, the microphone is acoustically isolated inside the instrument,
providing freedom of movement as well as minimal leakage from other instruments on stage.
