The most affordable model in our family, the
DM-141A
receives “off-air” or CATV
signals, processes these signals and provides two buffered composite baseband video outputs.
Additionally the DM-141A provides balanced stereo audio outputs which may be monitored
via the front panel speaker. Ideal for uses where quality video and stereo audio reception is
required. The DM-141A is used in headends, studios and remotes for monitoring and
retransmission applications.
DM-145
Like the DM-141A, the next model in the Videotek demodulator series, the
DM-145
,
is perfect for broadcast and cable applications and adds the capability of providing both
stereo audio and SAP (Second Audio Program) outputs. Second language programming,
emergency alert, or radio simulcasting are a few of the applications that require full time
SAP audio.
DM-145GCR
Like the DM-145, the next model in the Videotek demodulator series, the
DM-145GCR
, is
perfect for broadcast applications where the added capability of Ghost Cancellation
Reference (GCR) correction to the Video output is needed. Correcting for ghosts from +3 to -
42 µsec.
