Satellites have proven to be a reliable method of communication for distribution of CD-quality digital audio. The Integrated Digital Audio Distribution Network, of which the ABR200 is a key component, sets a new world wide  standard for digital audio distribution. The unique capabilities of the ComStream digital audio system allow a
network to start out small (offering a single monaural or stereo channel) and grow to a larger multichannel system without replacement of receiver hardware. Fast, easy selection of audio channels can be made either at the receiver or at the studio uplink.
