Model MBS

000A
Desktop
Paging Microphone
DESCRIPTION
The Bogen Model MBS
1
000A is a dual-impedance, uni-directional,
dynamic desktop microphone with a rubberized finish for all industri-
al and commercial public address and paging applications. The
MBS
1
000A has a bottom-mounted slide switch for low- or high-
impedance selection.The wide band frequency response is smooth and
peak free, thereby providing a natural, highly-intelligible sound.
The microphone output provides a normally open switch closure pair
that can be used to operate external equipment. When the micro-
phone is activated using either the push-to-talk or lift-to-talk functions,
the provided contact closes. The push-to-talk actuator bar includes a
locking feature to allow the mic to remain active for extended periods.
The lift-to-talk feature can be enabled or disabled using a bottom-
mounted selector switch.
Four molded, non-skid, non-marring, and permanently resilient "feet"
are located under the cast base.

IMPEDANCE
The Bogen Model MBS
1
000A is a dual-impedance microphone. The
high-impedance position is 50,000 ohms unbalanced and the low-
impedance is 500 ohms balanced. The low-impedance position is rec-
ommended for long cable length requirements. Cable lengths of
1
00
feet or more can be used in this position without loss of level or dete-
rioration of high frequency response.
