BMS series cascadable Headend Multiswitch with redundant dual power supply, in a 19″ rack mountable enclosure.


BLANKOM BMS-0512C is a high-performance 1x Satellite Multiswitch for digital TV broadcasting headend systems with a high end performance.

Designed for the modern 19’’ rack mounting installations. This professional Multiswitch can be cascaded and is useful to grow with your demands. If more Receiver outputs are needed – simply add a second device in your 19’’ Rack. (Up to 8 cascading devices in one chain are possible)

The LNB power can be set to ON or OFF to be almost flexible for the combination  with non-powered devices like optical LNB or similar optical transmitter – receiver couples like the BLANKOM BFT-44 (4x fibre transmitter) to BFR-44 /4x (Fibre receiver).

LED’s are showing the actual status as well as Gain adjustments for the 4 SAT levels are securing a flexible installation even with multiple LNB supporting.


Multiswitch optimized for use in DVB and IPTV headends.

Can feed headend equipment with SAT-IF signals of different satellites or can directly feed satellite receivers of housholds with IF+RF signals combined.
