Model MBS1000A  
Desktop  
Paging Microphone  
DESCRIPTION  
The Bogen Model MBS1000A 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  
MBS1000A 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 MBS1000A 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 100  
feet or more can be used in this position without loss of level or dete-  
rioration of high frequency response.
