Overview

DMB-24E Plus Series 8/12/16/20/24 Channels professional Trans-modulator, 4 Tuners ports per module, Up to 6 Modules in Back panel, demodulate to 4 separate multiplexing and Up-converter modulating adjacent carrier out.It also supports 2*independent HDMI/SDI input and output. The Tuners support DVB-S/S2/T/T2/C/ ISDB-T /ATSC-T optional input, Output RF standard support DVB-T/DVB-C/ATSC/ ISDB-T/DTMB option from UI, only need reboot the device after switch the output RF standard, IP Output 1*MPTS channels simultaneously.
This is an ideal solution for environments where you have a large number of air Channel, and widely used in IPTV System, Hotel, entertainment facilities, education broadcasting systems at schools and government buildings or any kinds of Source signals convert to Cable TV broadcast System, largely cost down the source gathering of Digital TV Broadcasting system and IPTV/OTT system which based on IP construction. Being the ideal multi-channel professional receiver used for FTA (free to air) IP signal source capture from digital tuner.
