The spring (made of tempered beryllium copper) provides the proper
tension for a snug fit in wing slots ranging from .060 inch to .090 inch (1.2
mm to 2.3 mm).
NOTE: For best performance, the wing slot opening should be exactly
.070" (1.8mm).
3. Once the transducer is properly installed in the bridge, attach the output
jack to the tailpiece with the black plastic tie wrap.
FINE T UNING
Once the V-100 is properly mounted, plug the instrument into an amplifier and
play at a low volume. Carefully shift the position of the pickup and listen for
the best location.
NOTE: If installation is to be permanent, a small drop of adhesive on the side
(lower face) of the transducer can be used.
PLUGGING I N
Due to the nature of passive pickups, the type of cable you use and the input
you plug into will affect the quality of your sound.
Instrument Cable
Cable lengths over 10 feet (before preamp) will cause audible high frequency
loss. Use a high quality, low capacitance shielded cable. This will ensure
minimal tone coloration and hum. Using fully shielded metal plugs will also
help eliminate hum.
Kinds of Audio Inputs
Because of the lack of standardization for high impedance audio inputs, special
attention should be paid to what you are plugging into:
The V-200 Professional will sound best when plugged directly into an input
with a 10 MΩ impedance; the full frequency response of the instrument is
reproduced.
The V-200 Professional can also be plugged into inputs as low as 1 MΩ with
adequate results; the bass frequencies will be slightly rolled off.
INSTALLATION
1. Measure the opening of the
wing slot on the bridge with a
vernier caliper. The opening
should be between .060-.090"
(1.5-2.3mm) for proper fit.
If the wing slot measures less
than .060" (1.5 mm), employ a
qualified repairman to enlarge
the wing slot.
If the wing slot measures more than .090 inch (2.3 mm) as is the case in
violas, a small wooden shim may be required. If so, use an adhesive to
bond the shim to the "leg" face.
2. Slide the V-100 Transducer into the wing slot of the bridge (See Fig.1).
Make certain that the sensing element is in contact with the wing face and
that the spring is in contact with the corresponding "leg" face of the bridge.

Preamps
We strongly recommend using a 10 MΩ, impedance matching, buffered
preamp in conjunction with the pickup.
A matching preamp will:
1. Realize the full frequency response potential of the pickup.
2. Permit long cable runs (after the preamp) without signal deterioration.
3. Allow precise volume and tone shaping with dedicated EQ.
4. Ensure compatibility with virtually any instrument level audio input
available.
Fishman Transducers manufactures a complete line of compatible preamps,
all with 10 MΩ inputs:
POWERJACK - Miniature Endpin Preamp
MODEL GII - Outboard Acoustic Instrument Preamp
PRO-EQ II - 4 Band Acoustic Instrument Preamp
PRO-EQ PLATINUM - Outboard Acoustic Instrument Preamp / EQ / D.I.
POCKET BLENDER - 2 Channel Pickup / Mic Preamp
Musical Instrument Amplifiers
Most musical instrument amplifiers (at least 1 MΩ input impedance) will yield
useable results. Acoustic instrument amplifiers have a 10 MΩ Piezo input,
ideally matching the pickup.
Direct Boxes
You can plug the V-200 Professional into an "active" direct box (1 MΩ to 10
MΩ input) with very good results. Using a passive direct box will sound weak
and thin.
PA / Recording Consoles
Professional PA and recording consoles have a much lower input impedance
than what is acceptable for the V-200 Professional ; you will need an
impedance matching preamp. Plugging a passive piezo pickup into a mixer
without an impedance matching preamp will sound harsh and thin.
