Default Re: Hotel Panel Radios

Attached are photos of the system I built to enable me to lisen to British radio here in the south west of France.

The system comprises a quattro LNB on the dish feeding a 16 outlet distribution amplifier. This feeds five satellite receivers (only four in the picture;one is faulty). These feed a home built five-channel power amplifier.

The signals are fed at 100 volts using telephone twisted pair to speaker units (the one shown is in my bedroom along with my work boots). The receivers run continually but the power amp is switched on by a DC phantom across the speaker feeds. When a station is selected, a DC path to earth is formed which operates a relay to power the amplifiers. The satellite dish also feeds televisions in various rooms.
