Since the DR 2 can receive lower frequency UHF digital signals, the unit works with external block down converters (BDC). The DR 2 can be supplied with BDCs that can receive a wide range of frequencies from 1.99 GHz to 7.1 GHz, depending on customer requirements.
"The architecture of the DR 2 offers communication between the external BDCs and the main receive unit, enabling the system to operate in different modes, such as wideband, tuned 1 or tuned 2, providing our customers with far more flexibility than similar systems on the market," says RF Extreme President Stephen Shpock.
The DR 2 is equipped with four RF inputs that communicate directly to the external BDCs, which form a maximum ratio combination that offers up to four input diversity receive signals. In using the external BDC, the Newscaster DR 2's receive antennas can be remotely mounted at a distance from the main unit. It is outfitted with an integrated COFDM demodulator, an MPEG2 HD/SD decoder, internal power supply, an integrated spectrum analyzer and an on-screen display.
