19'' Rackmount Multiswitch and a Matrix for the Digital TV Headend
High-performance 1x , 2x, 4x Sat-position Gateway devices for digital TV broadcasting headend systems
BMS-0512C: 1 SAT-Position - 12 Receiver out - cascadable
BLANKOM BMS-0512C is a high-performance 1x Sat-Position Gateway device for digital TV broadcasting headend systems with ahigh 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 7 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 fibre optic 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. Gain adjustments for all 4 SAT-IF Inputs (+ terrestrial) can be equalized. Designed to work and power even multiple LNB's connected (Single, Dual) in a mix to reach DVB-T-Station SAT receptions from multiple positions demanded like in France.

BMS-0932K: 2 SAT-Positions - 32 Receiver out - Cascadable
This cost effective 19 inch 3U headend multiswitch family (9/17) is designed to overcome the problems of traditional multiswitch mounting in 19 inch environments:
- Double industrial power supplies with high isolation have been used for fail-safe operation
- There is an active terrestrial input to supply also the DVB-T signal form
- Cascading (tap attenuation 0.5dB) with up to 8 of these multiswitches allows flexible adaptation to larger building cabling (SAT/Terr)
- Manual switching of the LNB supply voltage (cascades)
- Low input signal strengths are compensated by high amplification at the receiver outputs
- High RF isolation due to high quality direct F-connections on the boards
- Low current consumption due to new generations of SMD components
- LED indicators for each connected receiver port
- Uninterrupted air circulation through 2 separate fans
- Overvoltage protection up to 100V at the receiver outputs
and further arguments:
Main Features:
- Dual redundant internal high isolated industrial Power supplies
- Low power consumption, air circulation due to 2 separate fans
- Active TERR input (passive input available), LNB Voltage On/Off switch
- Quad & Quattro LNB compatible (internal 22KHz Oscillator),DiSEqC support
- 950-2150MHz and 47-870MHz lossless sharp filter for each subscriber outputs
- Low signal resistant due to high gain through the receiver outputs
- +4dB equalizer range for each RF output compensating slope
- Tap loss 0,5dB , High isolation
- Active TERR input (passive input available), LNB Voltage On/Off switch
- Optimized RF design for the usage of DVB IPTV and Digital Headends
- Up to 8 consecutive cascading’s possible

BMM-1716: The high compact BLANKOM Satellite – L-Band-Switch Matrix
- Professional RF design for DVB IPTV and Digital Headend’s
- Dual redundant power supplies
- Web-Interface: Remote adjustment by an Internet Browser
- LNB supply 13-18V, 13V-18V+22KHz and up to 3,5A in total, special versions w/o Network-Interface and with only 1 PSU available upon request
- Low power consumption
- Terrestrial passway included
This stunning cost effective SAT-MATRIX is equipped with a Web-Interface which can be operated by a normal browser via an Ethernet IP connection
– also remotely to flexible adjust and select every SAT-Input-port (incl. terrestrial pathway) to any of the 16 output ports to be routed or multiplied.
With the inbuilt RF-level monitoring circuit the user always gets the qualitative information about the signal and displayed in the web-interface.
In parallel the LNC powering is monitored and shown. This Matrix comes with dual redundant power supplies for securing highest reliability.
This high performance matrix operates fully autonomous and has been designed for modern 1RU 19’’ rack installations.
This SAT/T(2) matrix is an ideal equipment for a flexible SAT/T distribution as a Headend-Input selection from max 4 SAT-positions.
Even useful by using several units for the pre-selection of more than 4 SAT positions (incl. DVB-T/T2)
to active or passive distribution equipment like splitter/taps or cascadable Multiswitch devices,
it allows a flexible combination also for an almost complex SAT/T network serving multiple Signal-Input combinations.>
