The SIGNAL PRO MS-5xx series of multiswitches makes it possible to distribute signals from one satellite, terrestrial TV DVB-T2 and FM/DAB+ radio. SIGNAL PRO MS series multiswitches have been designed for operation in detached houses and small residential and office buildings. The multiswitches are designed for indoor operation.MS SIGNAL PRO multiswitches are series of professional pass-through/terminal multiswitches. They can be used to build a cascade of up to 4 devices (without a multiswitch bus amplifier). MS SIGNAL PRO multiswitches can be used as terminal multiswitches - then it is enough to terminate the loopthrough outputs with 75 Ohm terminating resistors with DC blocking R66205. High output signal levels (88 dBµV for the radio/DVB-T2 path and 100 dBµV for the SAT path) guarantee stable system operation. Thanks to their robust construction, high quality components and stable operating parameters, SIGNAL PRO multiswitches guarantee excellent signal quality throughout the installation.The zinc and aluminium alloy connector strips provide: effective class A shielding protection against interference excellent heat dissipation rigidity of the entire productKey features:5 inputs (4×SAT, 1×TERR)8 independent subscriber outputsshielding class A - cast housingPass-through design (cascadable)very good impedance matching (IRL > 21 dB)LED signalling on subscriber outputs - easy diagnostics of the installationexternal power supply DC 20 V 2.5 A with F connector included4-year warrantyWhen cascading SIGNAL PRO multiswitches, it is possible to power the whole set from one DC 20 V/2.5 A power supply, which is included in each multiswitch. This type of power supply allows for stable and safe operation of up to 4 multiswitches at the same time, which simplifies installation, reduces the number of components needed and reduces the cost of the RTV-SAT system. Importantly, this power supply also provides the voltage needed for the operation of the QUATRO type converter, so there is no need for additional power sources.Multiswitches of the SIGNAL PRO series have been equipped with LED indicators assigned to individual subscriber outputs. This allows the installer to quickly and conveniently check the correctness of the signal in each output point of the multiswitch. This solution significantly facilitates the commissioning and subsequent diagnostics of the installation, allowing for immediate localisation of any problems in signal distribution. The presence of a connected receiver (tuner, meter) is signalled by the illumination of the LED assigned to the relevant multiswitch output. If the diode is not lit for an active subscriber connection, this usually indicates a problem with the cable (short circuit, interruption), the outlet or the receiver itself.Frequency characteristics of SIGNAL PRO multiswitches in DVB-T2/Radio path (47...860 MHz):blue colour - input return loss - high impedance matching, guaranteeing minimal signal reflections.

Through the use of cast connector strips, the unit effectively eliminates the effects of electromagnetic interference (EMI) and unwanted signals from the environment. This design ensures undisturbed transmission of satellite and terrestrial signals, even in harsh installation conditions especially in environments exposed to high radio signals, such as near GSM, Wi-Fi or LTE transmitters.Zinc and aluminium alloy castingsThe zinc-aluminium alloy casting is characterised by high resistance to mechanical damage and corrosion resistance, which is important in installations exposed to variable environmental conditions (e.g. in technical shafts, cellars, attics). In addition, this ZnAl alloy metal housing acts as a heat sink to effectively dissipate heat, which increases the life of the components and minimises the risk of the unit overheating. LEDs indicating the occupancy of the outputs===The LEDs on the top cover inform the installer of the occupancy of the individual outputs. In addition to their informative function, they are sometimes helpful in diagnosing the source of a problem in the installation. The LED lights up when a receiver, meter, etc. is connected to a particular output. If the diode is not lit for an active subscriber connection, this generally indicates a problem with the cable (short circuit, interruption), the socket or the receiver itselfHIGH SIGNAL OUTPUT LEVEL DVB-T2/DVB-S2Maximum signal power level at multiswitch output of: 88 dBµV for radio
