Multiswitch Terra MSR-532 (5-in, 32-out, terrestrial TV amplifier)
Producer: Terra
FULL DESCRIPTION
This kind of multiswitches is dedicated for small (4-24 outlets) and medium (25-72 outlets) SMATV systems with distribution of the first SAT intermediate frequency and terrestrial TV signals. It has RF pre-correction and cable length compensation (groups of inputs with different output levels). For installations with above 24 outlets there are needed additional multiswitches. Signals from Quatro LNB and terrestrial TV antennas should be first split/tapped through TERRA splitters or taps. The multiswitches of MSR series have to work inside buildings.
Work safety
The device is powered with 230VAC power network. All precautions for working with dangerous voltages should be observed!
Multiswitch operation
The following voltages occur at the inputs of the multiswitch:
  • 18VDC at H, Lo and H, Hi inputs
  • 14VDC at V, Lo and V, Hi Inputs
  • 12VDC at the input of terrestrial TV. This voltage enables to power a preamplifier. In case no amplifier is used, the voltage can be switched off.
