[cma-l] Radio Link Transmission systems

[Mike Davison]

We switch our studio(s) off when fully automated and have the switching 
mixer, network switch, RAID master programme and music NAS computer, 
logging computer, main auto play-out computer, satellite receiver, audio 
processing, limiting and stereo encoder, and the link transmitter on a 
large UPS. Presenters are encouraged to always let the computer handle 
the IRN bulletin during their live programmes so the satellite audio 
never has to go through any desk directly and in fact all the station's 
desk-feeding computers have the IRN audio piped to them to allow 
recording of any special item manually in a separate studio. The 
switching mixer has four feeds, studios(2), main play-out computer and 
standby play-out computer. I suppose every station has its own methods 
and this is ours at Tempo FM.
