The Digital Audio Uplink, along with the Comtech Tiernan Video family of SCPC audio receivers, builds a network that gives you the most reliable and cost-effective audio distribution you can buy. These products were the first to utilize the industry standardISO/MPEG Layer II audio compression, saving you 35 to 65% in recurring satellite transmission costs when compared to alternative networks.

ComtechTV digital audio networks are in use in more than 50 countries, sending audio information to customers of these diverse businesses:• National radio networks, including multiple

channels for different languages• Automated commercial radio distribution• Interactive audio information, or “audiotext”• In-store audio for retailers with regional ads

The uplink includes the Codecs, modems, andredundancy switches in a prewired audio rack. Built into each audio uplink rack is an ABR202receiver that can monitor the audio, data, and relay closure signals being transmitted on any channel. The Audio Network Management System and RF Terminal are available as options.

Each digital audio channel includes audio, anRS-485 network control channel, up to 16 input cue signal controls, and asynchronous RS-232 userdata. All inputs are multiplexed and compressed intoa single digital data stream for transmission.

The multichannel rack includes an audio patch panel so that you can monitor all critical points within the audio path for each channel, reroute signals, and patch between channels. Or monitor audio right from the rack using the built-in audio amplifier with speakers and headphone jacks.A two-channel VU metering system provides accurate, individual signal-level monitoring.
