A variety of microphones can be used with
the Pocket Blender. However, the Crown
GLM-200 is our microphone of choice for the
system. It is a mini-electret condenser
microphone with a hyper-cardioid response
pattern. It's high SPL rating (130 dB), small
size and crystal clear "rising" frequency
response make it ideal for close mic'ing
acoustic stringed instruments. We offer the
GLM-200 optimized specifically for use with
the Blender System.
The Pocket Blender provides 9-Volts of
Phantom power to the GLM-200 via the tip
terminal at the input jack.
A small zener diode is included with the
GLM-200 microphone. It is pre-wired to both
the Bass and Violin jack assemblies
(BMA,BP-100-M, V-200-M). It is included
separately with all other kits. It must be
installed for the microphone to be covered
under warranty. The zener diode prevents
static electricity from damaging the
microphone.
The GLM-200's small size allows it to be conveniently mounted in or outside the sound chamber of most stringed instruments. The
microphone, with a (TRS) stereo jack included, can be attached to the instrument using one of the following mounting systems:
GMA - Guitar Microphone Assembly
The Microphone is mounted in the sound hole with a clip that
attaches to the X-brace under the instrument's soundboard.
The jack is run through the instrument's endpin hole.
Soldering and some assembly is required.
BMA - Bass Microphone Assembly
The mount attaches to a bridge foot with an adhesive backed
nylon clip. The jack (pre wired to Tip) mounts between
the A & D strings. Also available with a pre-wired pickup
(BP-100M).
V-200M Pickup and Mini-Mic
The mount is integrated into a Carpenter-style jack that
attaches above the instrument's chin rest.
M-200M Mandolin Pickup and Mini-Mic
The mount is integrated into a Carpenter-style jack that
attaches to the mandolin's lower bout.

1. Remove shielding cap to expose preamp circuit board.
2. Connect red microphone wire to ring pad on circuit board.
3. Connect white and shield microphone wires to "G" pad adjacent to ring pad.
4. Connect supplied zener diode in place between red wire and sleeve. Note that banded side of the zener diode
must be closest to red microphone wire.

The advantages to wiring the microphone and pickup to separate mono connectors are:
a. Microphone is interchangeable with other instruments.
b. Less cross talk between passive pickups and the microphone.
Typically, classical guitarists and double bassists find this arrangement convenient for sharing the microphone with
several different instruments. Classical guitarists can install the microphone without drilling holes in the instrument. In
this configuration, the microphone can also be removed without disturbing the pickup.
1. Connect red microphone wire to tip terminal on a ¼" mono plug.
2. Connect white microphone wire and shield to sleeve terminal the same plug.
3. Solder supplied zener diode in place between red wire and sleeve.
Note:
The banded side of the diode must be closest to the red wire. For use with the Pocket Blender, plug the mic into the
RING jack of a stereo "Y" cable (available from Fishman).
Warning: Installation by a qualified repairperson is strongly recommended. Fishman Transducers Inc. will not be responsible
for any damages due to improper installation.

To get up and running you'll need these components:
• Pocket Blender
• 9-Volt alkaline battery
• Pickup and mini-microphone connected to a stereo jack (See Page 3)
• Stereo instrument cable
• XLR cable or 1/4" instrument cable
1. Install a fresh 9-Volt alkaline battery.
2. Connect the stereo cable between the instrument and the input of the Pocket Blender.
3. Set the Mute, Lo and Hi switches to the out position. Set the phantom power switch on the rear panel to the in
position. Set both channel volume controls fully counter clockwise. Set the Master level to 3:00. Set all the bass
and treble controls to 12:00.
4. Run a cable from one of the outputs on the rear panel of the Pocket Blender to your amp or PA.
5. Adjust the trim controls - See Page 7
6. With the Pocket Blender's Master Level at 3:00, adjust both the microphone and transducer volume controls to
approximately the same level.
7. Set the phase switches - See Page 6
