Make sure the unit's power switch is turned off before removing the cord from an
outlet.
zx w Disconnect the mains cord when the unit is not in use for long periods of time or
during storms.
zx w Do not connect the unit to a multiple-outlet to avoid plug overheating.
Disassembling
zx w This unit contains parts that cannot be repaired by the user. Do not disassemble
or try to repair it as this will void all warranties. Please contact the manufacturer if
you experience any problems with your unit.
Water/humidity
zx w Do not keep the unit in a humid place or near water.
zx w Do not plug/unplug the unit with wet hands.
WARNING
The following safety precautions must be observed to prevent fire

Fire
zx w Never place a candle or another source of fire on the unit as it may fall and start
a fire.
zx w If the mains cord or the power connector is damaged or destroyed, or if there is a
sudden loss of picture during operation, or if you notice a strange smell or there is
smoke, immediately switch the unit off, disconnect the mains cord and contact the
manufacturer’s technical support department.
Installation / Storage
zx w This unit contains high precision pieces of electronics. To ensure optimal perform-
ance and avoid damage, do not store it in any location where it may collect dirt,
duct, lint, etc. Do not expose it to extreme heat or cold (e.g. in direct sunlight, near
a heater or in the car during the day). Place the unit in a secure place to avoid falls.

2. INTRO
Congratulations on purchasing the MLF-301. You now own a high quality, professional
DTV headend. To get the most out of your purchase, please take the time to carefully
read through this manual.
3. INSTRUCTIONS
3.1 - Description
The MLF-301 is a very powerful, all-in-one device, able to receive up to 4 independent
satellite (DVB-S/S2/S2) signals and convert them in 4 x DVB-T/C RF output channels
or in IPTV streaming using UDP/RTP protocols multicast/unicast. The MLF-301 is ca-
pable of receiving any kind of multi-stream signals too. It supports “pool” technology,
meaning that the user is able to select any program from any of the 4 inputs and as-
sign it to any of the 4 RF or IP outputs providing great flexibility.
The embedded web server of the MLF-301 provides a very friendly user interface as
well as the ability of remote or local control of the device via Ethernet.
Its small size and its powerful features render the MLF-301 the ideal solution in cases
we want to distribute FTA (Free-To-Air) TV programs coming from satellite (DVB-
S/S2/S2X) sources to a CATV installation using the DVB-T/C or IP technology.
3.2 - Features
zx w 4 x independent multi-standard inputs DVB-S/S2/S2X
zx w Multi-stream support
zx w 4 x RF output DVB-T/C (software selectable)
zx w Gbit IP streaming (up to 64 x SPTS / 4 x MPTS)
zx w “Pool” technology
zx w MER value > 42dB
zx w Dual power supplies offering redundancy mode
zx w PID Filtering
zx w Custom NIT/SDT
zx w Local or remote control via webserver
zx w Very friendly user interface
zx w Wall or rack mount options
zx w SNMP v2
zx w Ultra-compact size
zx w 5year warranty
3.2.1 - Auto-reset functions and watchdog
During the normal operation of the MLF-301, the main CPU monitors all the internal
parts in order to ensure that the device works normally. In case of an internal error or
module failure, the MLF-301 immediately initiates the recovery procedure by resetting
the appropriate module or the device. Finally, watchdog timers ensure that the device
will be reset in case of CPU failure.

3.2.2 – Multi-stream SAT reception
The MLF-301 is able to receive and analyze any kind of multi-stream satellite signal.
3.2.3 - “Pool” technology
The MLF-301 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.
3.2.4 - 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-301 without the need of any firmware upgrade.
3.2.5 - IP streaming
The MLF-301 is able to make IP streaming of all programs coming from the 4x RF in-
puts using UDP or RTP protocol in multicast/unicast IP addresses. The max. output bi-
trate can be up to 480 Mpbs.
3.2.6 – Custom NIT/SDT
Using the MLF-301 the user is able to create custom NIT and SDT tables according to
his needs.
3.2.7 – Dual power supplies
The MLF-301 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 con-
tinue working without stoping.
