ADJUSTMENT OF SELECTOR
SWITCHES
SPECIFICATIONS
The
tone selector switch,
the
directivity selector switch
and the pad
selector switch
are
located
inside
the
microphone under
the
rear
cover.

TONE SELECTOR SWITCH
The
tone selector
switch
adjusts
the
low frequency
response.
V
position
reduces the response
in
the low frequency
range. When
some room acoustics
happen
to
emphasize
low
frequencies,
resulting
in "boomy"
sound pickup, or when
a
microphone is
plac-
ed in
close proximity to the
source,
causing a
"proximity"
ef
fect
(a
boosting
of the
bass
response),
set
the
selector
switch to
V. This
position
is
preferable
for
closemiking
of
voice,
and
in
situations
where
air conditioner
noise or
cthar
sources
of 'c,.i'f.e:;e1a',

DIBECTIVITY SELECTOR SWITCH
The desired
directivity can
be
obtain
by
setting
the
directivity
selec'
tor
switch.
When
the
power
is
turned on, the directivity indicator
will
be
il-
Iuminated and the
directivity in
use
can
be checked.
C :
Omni.directional
Sounds from
the all directions
are picked
up
with
equal
level
Q :
Uni.directional
Sounds
f
rom
the

ront
are emphasized.
8 :
Bi-directional
Sounds from the
front
and
the
rear
are emphasized.
PAD SELECTOR SWITCH
The pad
selector switch
reduces the
output
level
of the microphone
to
prevent any overload of the
impedance
translator
resulting from
the pickup
of
extremely high
level
sound sources. Normally
set
the
selector
switch to
0,
and
when
the recording
of
high sound
level is
necessary, set
this
to
10.
