Drake DAD860A Digital to Analog Decoder provides digital demodulation and decoding, for ATSC 8VSB broadcast or in-the-clear QAM television signals. The DAD860A delivers a standard NTSC composite analog video and stereo audio output. It may also be utilized to provide the alternate digital channels now available from many broadcasters. The DAD860A modules may be intermixed with analog modulators from the Drake VMM mini-rack series, all powered by a single PSM121. This allows an analog demodulator to be replaced by a DAD860A while reusing existing analog modulators.
