“When we use the new HD FlexMic for our worship services, here is what we
notice: (1) there is a phenomenal clarity in the sound (almost like there was
no microphone there at all), (2) the intelligibility is incredible, and (3) it has
mic has a much further reach both on and off-axis.”

Franklin Denham, Minister of Music, Highland Baptist Church, Meridian MS

• Available in Cardioid or Hypercardioid

• Available with Fully Flexible Gooseneck in
Short or Medium Lengths

• Available with Rigid Center Gooseneck with flex at
both ends, in Short, Medium or Long Lengths

• Optional PMM1 Podium Mount Accessory

The new Earthworks High Denition FM Series offers spectacular
results and will outperform any other podium microphone at any
price. The FMHD microphones will allow you to hear more detail
with greater clarity than previously possible. Just plug one into the
XLR connector on a podium and you will nd the audible results
absolutely incredible. The new FMHD podium microphones are the
perfect choice for those who demand only the very best and are
ideal for use in civic centers, boardrooms, educational facilities,
theatres, churches and houses of congress.

Earthworks patented technologies provide high intelligibility and
uniform off-axis response to ensure that the orator is always heard
and well understood at the front, at the sides, below or above the
microphone. This smooth off-axis response also provides more
gain before feedback and a over 30dB rejection of sounds behind
the microphone. With 139dB SPL max acoustic input, it is virtually
impossible to overload the microphone and there is no microphone
handling, noise in addition to incredible RFI rejection.

The Earthworks FMHD Series models offer you a variety of choices
with fully exible goosenecks or goosenecks with rigid centers that
have ex at both ends. All models are available in either cardioid
or hypercardioid polar patterns. The optional PMM1 podium mount
will work with any FlexMic™ Series model. If you haven’t heard an
Earthworks High Denition FlexMic™, you are in for an real surprise!

Architectural & Engineering

The microphone shall be a back-electret con­denser type with a wide-range uniform fre­quency response of 20 Hz to 40 kHz. The mi­crophone shall have an output level of 10 mV/
Pa. The microphone shall be of a single capsule,
single membrane design. The microphone shall
have an impulse response with the rise time no
longer than 25 microseconds, and total settling
time, including the rise time, no longer than 120
microseconds. The microphone shall have po­lar characteristics uniform in all planes to form
either a cardioid or hypercardioid of revolution.
Response at any angular position up to 90° away

from the major axis within frequency range from

500 Hz to 16 kHz shall deviate by no more than
±3 dB from the ideal cardioid or hypercardioid
pattern as described by the following equation:
SPL(a)=20*Log(1/2+cos(a)/2) (dB), where a is
the angle in radians between the measurement

source position axis and the major axis. The

microphone shall accept sound pressure levels
up to 139 dB producing no more than 3% THD.
Overall length above the XLR connector shall be

12.5 in. (31.8cm) long for FM360HD and 18.3 in.
(46.5cm) long for the FM500HD. The maximum
head diameter shall be 1.0 in. (25 mm). The
microphone shall be terminated with a profes­sional gold-plated 3 pin XLR connector. The mi-

crophone shall include an external windscreen.

The microphone shall require 24-48V phantom
power. The microphone shall be made of metal

with black nish. The microphone shall have its
entire exible portion encased in black vinyl.
