BMS-1732K
We strongly recommend the installation by technical skilled people.
All needed connection to the LNB’s SAT-A...D as well as the cascading outputs are printed to the
rear and front-panel so that a mismatching usually cannot be done. Please assure the grounding of
every component (BMS, Coax cables as well as Antennas/dishes) to avoid voltage differences
between every device. The grounding should also be fit to earth potential to secure them against
lightning influences.
The BMS supports cascading to a following unit to double or even multiply the needed output
numbers. (32 -> 64 -> 96...) A cascading of more than 7 units is not recommended because of the
attenuations of each. The cascade units should disable the power
Before you connect the both power supplies to the power source by the power cords, please
connect all coax-cables and the max. 4 LNB’s or the optical – electrical fibre receiver to it.
Please take care about not making any Coax- shortages and check the cables before power
connecting. The device runs with only one PSU connected. The 2nd PSU is in standby just in case the
first one will fail –and will take over the power-loss job. So it is recommended not to connect them
both to the same power-line and fuse system:
AC 220V 50Hz supplying please!
Both have one small fuses –just in case something happens... control these.
Remark: The LNB-powering can be switched OFF (default is = ON) by the front panel switch.
Connected optical receiver -> electrical changer installed before the unit in between LNB’s and the
SAT Inputs of the BMS-1732K -like our BFR-41 or similar- do not need the LNB powering ON –so
you can switch it to OFF.
Active Terrestrial Input and distribution to every output:
The unit comes with an additional terrestrial Input F-Connector serving DVB-T/T2 frequencies to
pass through to the output receiver ports. The terrestrial output depends of course from the
amount of energy you provide into its Input. These needs to be carefully balanced and eventually
before the switch input: Attenuated or amplify to raise best conditions for the pathway of the
combined Terrestrial and satellite frequency range. As example for an active T-Version: 5dB
difference which means the terrestrial output signal is 78% less (remember: 3dB = 50%) at the
Multiswitch output by optimal Input values. So the signal quality -as a distribution component- to
all the end user wall-outlets is much better by the active internal T-Amplifier- but need to be balanced
to not overload it.

Shown is a good quality output level of 80 dBµV directly from a BLANKOM 32 -> 32 -Multiswitch
cascaded output. The first 2 showing ASTRA Satellite high band while the 3rd shows Eutelsat
Hotbird 13°E on DiSEqC SAT Pos. 2 with a better adjusted LNB at the dish(es). So your signal quality
depends on: Dish direction and angles, LNB focus and angle and also its LNB-quality and the cable
length and quality.
