Through our Eulomogo Transmitter(1251AM) and Cobar Translator (972AM), 2DU reaches an audience of up to 65,000 in the area shown in our broadcast 'footprint' (right).

Dubbo city is our largest population centre, with our signal also serving many surrounding towns, including Narromine, Gilgandra, Wellington, Coonamble, Cobar, Peak Hill, Coonabarabran, Dunedoo, Warren, Trangie, Mendooran, Nyngan, Yeoval and Gulargambone.

At the studio various studio signals from microphones, computers, turntables, tape recorders, cartridge machines, CD players, the satellite receiver and landlines from outside broadcasts and network programs, are mixed together using a mixing console.

The various knobs and switches control this mixing and the final result is known as the program.
