MOBILE MIC. with amplifier
Conveniently small hand-held mobile microphone has a built-in
solid-state amplifier, offers fixed station operating convenience in motion! A rear
control with calibrated thumb wheel allows speech gain to be set for optimum modulation
under prevailing background noise conditions. Amplifier is powered from internal penlight
cells and is capable of more than 15db gain. Microphone has coil cord fitted with
4-conductor plug.
NC-100 MOBILE NOISE CANCELLING MIC.
SBE noise cancelling microphone makes mobile operation far
more pleasant, avoids needless repeats by substantially reducing extraneous noise pickup
that is ever present in cars, trucks, other vehicles driving on highways. Special acoustic
design uses noise input from an extra sound port in the top of the unit to provide a
modified cardioid sound pickup pattern. Noise rejection is lodb or more to the front. 20
db or greater to either side. Microphone operates with all SBE transceivers having
4-conductor male microphone input. |
