GS1
WALL / CEILING MOUNT MICROPHONE
OVERVIEW
The GS1 is an innovative flush-mount wall microphone that can also be used as a
ceiling microphone when drop ceiling tiles are not available. Designed for distance
miking, the GS1 features include a fully integrated preamp, an extremely high
sensitivity rating of 38 millivolts, and complete immunity from RF interference
caused by cell phones and GSM devices.
The GS1 capsule is housed within a patented cradle that enables the microphone to
be aimed up to an angle of 45 degrees towards the sound source. Its small footprint
and flush-mount configuration allow the microphone to be unobtrusive without
sacrificing sound quality.
The GS1 terminates in a terminal block connector and is easy to install into a
standard single-gang box. A 2.75-by-4.5-inch mounting plate is included. The GS1
comes in stock satin nickel finish and is also available in white.
