17in/17out+20 compact cascadable multiswitch for distribution terrestrial and satellite signals from 4 satellite positions (16 polarities) to 20 users.
The multiswitch is DC supplied from connected satellite receivers, 2.1 socket for external power is connected to all satellite trunk lines. DC power is present at the TERR line, avoid short circuit!
Using a rotary trimmer it is possible to switch terrestrial band fromactive to passive mode.
The loss at user outputs in satellite band is adjustable by another rotary trimmer in the range 5-20dB. The attenuation at the outputs can be set by means of the trimmer together for each five outputs.
The multiswitch requires DC power from an external + 12V DC power supply. For the entire cascade of multiswitches only one power supply is sufficient. Do not use a higher voltage source as the power consumption of the multiswitch increases unnecessarily. We recommend the use of the EMP Centauri source PA12 2A, which is characterized by sufficient durability and low noise level.
