MSR 524 multiswitch has 4 inputs for a quatro lnb and 1 terrestrial input. The multiswitch provides 24 completely independent outputs carrying satellite and terrestrial signals. The multiswitch is for internal use only.
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.
