UNIVERSITY SOUND MM-2 SUBMERGENCE PROOF SHIPBOARD SPEAKER
The Electro Voice MM2 series air
speakers (MM2, MM2F, MM2TC) are designed for use on ships and
emergency vehicles for intercom and voice paging applications.
Since they have 25 watt rating, they are not for use as a siren
speaker for 100W or 200W electronic sirens. The MM2 series has a
submergence proof design (U.S. Navy spec), not damaged by water,
live steam or mist (not for use as an underwater speaker). The MM2 series
includes three models: the MM2, MM2F, and MM2TC. The MM2 comes
with a serrated mounting bracket allowing unit to swivel through a
90 degree vertical arc when mounted on walls, ceilings, vehicle
roofs, etc. The MM2F has a mounting flange allowing unit to be
mounted in a 6.625" circular cutout. The MM2TC has an integrated
transformer housing allowing installation of optional 25V/70V
transformer (part no. 5030) for remote locations requiring long
cable runs. The MM2 series is ideal for wet above water locations
including docks, bridges, boiler rooms, railroads, fire trucks,
and ships. These units are fully protected against damage by high
humidity, salt water, and many other environmental conditions. The
fungicide-treated, plastic-impregnated diaphragm is easily
accessible for cleaning. The MM-2 series are usable as warning
speakers, yet have sufficiently wide range response for excellent
voice reproduction in paging applications.
