3.2.5 – Dual power supplies

The MLF-101 is powered from one or two external power supplies of +12VDC/2.5A. In case we connect two external 

power supplies then they will work in redundancy mode. Thus, in case of failure of one of the two external power 

supplies the device will continue working without stopping.

3.2.6 – Multi-stream SAT reception

The MLF-101 is able to receive and analyze any kind of multi-stream satellite signal.

3.2.2 - “Pool” technology

The MLF-101 supports “pool” technology, meaning that the user is able to select any TV or Radio program from any 

input and assign it to any of the 4 outputs providing great flexibility.

3.2.3 - DVB-T or DVB-C compliant

The user is able to software select the modulation standard, between DVB-T and DVB-C, of the MLF-101 without 

the need of any firmware upgrade.

3.2.4 – Custom NIT/SDT

Using the MLF-101 the user is able to create custom NIT and SDT tables according to his needs.
