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

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',
are
en
co u nt ered

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.

: Bi-directional
Sounds from
the
front and the

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.
