Tax included
The MR-512 multiswitch is a professional radial device designed for modern antenna installations in small and medium-sized buildings. It allows for efficient distribution of satellite signals from one position (e.g., HotBird or Astra) and DVB-T2 terrestrial TV signals to 12 independent reception points. It is an ideal solution for single-family homes, residences, and offices where the highest signal quality without interference is required.
A key advantage of this model is its design based on star topology, which means that each receiver is connected directly to the central device. This solution guarantees maximum signal separation and facilitates system maintenance. The device's die-cast housing ensures the highest standard of shielding (Class A), which effectively eliminates the influence of external electromagnetic interference, such as LTE or 5G network signals, which often cause 'pixelation' on TV screens.
The device has built-in cable characteristic pre-correction, which automatically compensates for signal losses resulting from the length of coaxial cables inside the building. Thanks to the active terrestrial TV path, the DVB-T2 signal is amplified, which allows for avoiding the use of additional mast amplifiers. The multiswitch is powered directly from the 230V mains, which ensures operational stability and eliminates the clutter associated with external power supplies. By choosing a TERRA brand product, you are opting for European quality and reliability confirmed by years of experience in the telecommunications industry.

Specification
Signal inputs
4x SAT (950 MHz ... 2400 MHz), 1x Terrestrial TV (47 MHz ... 862 MHz) - active path
Subscriber outputs
12 F-type outputs supporting the full frequency range 47 MHz ... 2400 MHz
Control signals
Polarization and band switching using 14 V / 18 V and 0 Hz / 22 kHz signals
SAT gain
Adjustable in the range from -2 dB to 8 dB (includes cable pre-correction)
TV gain
Adjustable in the range from -3 dB to 5 dB (active path)
Input separation
Isolation between SAT/SAT inputs is a minimum of 30 dB
Output separation
Isolation between SAT outputs is 30 dB, for DVB-T it is 35 dB
Maximum SAT output level
96 dBµV (ensures clear reception even in extensive installations)
Maximum TV output level
In the range from 84 dBµV to 88 dBµV
Preamplifier power supply
Built-in function for transmitting 12 V DC voltage to the terrestrial antenna
Device power supply
Built-in 230 V AC (alternating current) power supply
Housing construction
Metal casting ensuring Class A shielding and optimal heat dissipation
Installation topology
Radial (star) - ideal for single-family homes and offices
Compliance with standards
Full compliance with CE standards and DVB-S2 and DVB-T2 digital transmission standards
Software and control
The device operates in Plug&Play mode, which means there is no need to install external software. Signal distribution management takes place in real-time via advanced multiswitch logic circuits. The system automatically recognizes and executes DiSEqC commands and control voltage changes sent from users' satellite tuners. As a result, switching between polarizations (vertical/horizontal) and bands (low/high) occurs instantly and flawlessly, ensuring maximum user comfort without system delays.
