TERRA class A Multiswitch MSR916 9-in, 16-out Multiswitch with Active Terrestrial Path
Terra MSR916 multiswitch has 2 x 4 LNB inputs from two quatro lnb's and 1 x terrestrial input feeding 16 completely independent outputs. The device has been designed for distributing 2 satellite signals and terrestrial signals to a number of users (SMATV systems). It is compatible with all satellite platforms.
Distinguishing features
- radial topology
- built-in cable loss correction
- groups of outputs with different output levels
- isolation between outputs better than 25dB
- powering of optional terrestrial TV preamplifier
- built-in power supply
- LNB powered through H lines
An important advantage of MSR-9XX multiswitches is diversification of signal levels at different outputs. It allows to compensate the differences in attenuation of various lengths of cables that have to be used in the installation - we can get similar levels in all outlets. Additionally, the multiswitches compensate cable characteristics (provide higher levels for higher frequencies).
The device is powered with 220-240 VAC power network. All precautions for working with dangerous voltages should be observed!
The following voltages occur at inputs of the multiswitch:
- 18 V DC at H,lo and H,Hi
- 14 V DC at V,lo and V,Hi
- 12 V DC at terrestrial signal input, suitable for powering an antenna preamplifier.
