Headend system by Anttron suitable for hotels, nursing homes etc
- 4 Satellite Input
The TRM84 is composed of a 3RACK with a DTVRR12 and DTVDM4F module. The combination of these modules
allows the conversation of satellite signals using DVBS or DVBS2 modulation in DVBT or DVBC signals.
The DTVRR12 module has 4 inputs and integrates a 4x8 multiswitch. The 8 tuners (A,B,C,D,E,F,G,H) can select the
satellite signal from inputs 1,2,3 and 4. After demodulation the received programs are available as a transport stream
and are then fed into the DTVDM4F modulator.
The DTVDM4F is a 4 channel fl exible modulator. The modulation can be DVBT or DVBC. The output of the 4 channels
can be freely selected in the VHF and UHF range. The level of each output channel can be adjusted indepedently
