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.

When changing the settings, be sure to turn off the amplif ier to pre-
vent microphone output noise that could damage the speaker or
create a disturbance.
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 .
Generally keep tne se ecior st'i tcn lc l',,1 {or a m-s a sollrce.

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 f 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.
