★DescriptionDT-DQAM-M3204B is a new compact (1RU only) chassis
and cost-effective QAM modulator with multiplexing function, which
is designed by Hangzhou Prevail according to the DVB related
standards. DT-DQAM-M3204B has 4 ASI input (Max. bit rate of
each channel up to 108Mbps), one of RF output and RF testing
output. The DT-DQAM-M3204B has very convenient and friendly
management interface, the user can complete all operation via local
keyboard and LCD display on device, or access through the Ethernet
port on device.★Feature⊙Up to 4 ASI inputs⊙Up to 108Mbps bit rate
