CMA-9 Condenser Microphone
The
CMA
‐
9
is
a
professional
condenser
microphone
used
for
stage,
studio
and
broadcast
applications.
The
CMA
‐
9
guarantees
a
clear,
accurate
response
and
flexibility
to
handle
close
or
distance
miking
for
a
wide
variety
of
acoustic
instruments.
With
a
frequency
response
from
25Hz
to
20kHz
the
DMA
‐
9
condenser
mic
is
an
excellent
choice
for
cymbals,
hi
‐
hat,
drum
overhead
and
ambient
room
miking.
The
microphone
adopts
a
25mm
pure
gold
large
diaphragm
capsule,
which
has
a
cardioid
polar
pattern.
The
CMA
‐
9
comes
with
a
strong
shock
mount
system
(SHM1)
that
minimizes
transmission
of
mechanical
noise
and
vibration
For
higher
sound
pressure
levels
the
pre
‐
attenuation
of
‐
10dB
can
be
applied.
With
the
build
in
Low

filter
(bass

you
can
reduce
picking
up
frequencies
from
150Hz.
The

includes
the
brass
housing,
