The R.L. Drake model MQM1000 is a professional quality, digital headend transcoder
that accepts one or two MPEG2 digital inputs via two Asynchronous Serial Input (ASI)
connectors. These signals must be ATSC compatible streams if multiplexing is to be
performed and usually will have originated from a local TV broadcast station and may
have been transported over fiber links to the MQM1000. After multiplexing and null
packet management, the MQM1000 QAM modulates and up converts onto any
desired CATV or off-air output channel between 54 and 1002 MHz. The MQM1000
can also operate as a non-multiplexing QAM modulator when a single ASI input is
selected.
Features
• Front panel display and buttons allow easy setup and monitoring of operating
mode and parameters.

er are built in.
• Output is agile on CATV or broadcast channels from 54 to 1002 MHz.
• Dual ASI Inputs.
