A variety of microphones can be used with the Acoustic BLENDER. However, the Crown
GLM-200 is Fishman’s microphone of choice for the BLENDER System. It is a mini-elec-
tret condenser microphone with a hyper-cardioid response pattern. Its high SPL rating
(130 dB), small size and crystal clear "rising" frequency response make it ideal for
close-mic'ing acoustic stringed instruments. Fishman offers the GLM-200 optimized
specifically for use with the BLENDER System.
The BLENDER provides 4.5 Volts of Phantom Power to the GLM-200 via the MICRO-
PHONE channel. Phantom Power is sent through either the Ring of the STEREO IN
jack (for stereo cable use) or the Tip of the AUX/MIC IN jack (for mono cable use).
A small zener diode is included with all GLM-200 Crown microphones. It is pre-wired
to both the Bass and Violin Microphone Assemblies. It is included separately with all
other kits. It will prevent harmful electric spikes from damaging the microphone.
NOTE: The zener diode MUST be wired to the output of the GLM-200.
(Microphones
installed without the zener diode are not covered under warranty.) However, it is not
needed when a SMART SWITCH is installed.
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 instru -
ment 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 MIC ASSEMBLY
The microphone is held in a isolation collar to reduce low frequency microphon-
ics which are common with bowed instruments. 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-100-M).
V-200-M PICKUP AND MINI-MIC
The microphone is held in an isolation collar to reduce low frequency microphonics
which are common with bowed instruments. The mount is integrated into a Carpenter-
style jack that attaches above the instrument’s chin rest.
UNIVERSAL MICROPHONE ASSEMBLY
For mandolin, banjo, dulcimer, harp. A small alligator clip at one end holds the microphone. At the
other end, a set of firm gripping rubber-covered jaws attach to the instrument's housing.
