J. W. Davis DM-1A
FEATURES
DESCRIPTION
The DM-1A is specifically engineered for
paging, dispatching and radio applications.
The balanced, dynamic microphone element
provides a unidirectional, cardioid pattern with
noise cancellation that permits clear voice
reproduction in noisy environments and affords
maximum gain before feedback. Low imped-
ance allows a longer cable run from the micro-
phone to the amplifier without encountering
interference. Push-to-talk and hands-free,
lock-on switches provide operational adaptabil-
ity. A flexible 9.8'
four-conductor, shielded
cable is attached.
