The DTX is a phone-in system for radio and television broadcasters which incorporates digital sound processing techniques to provide exceptionally high sound quality.
The DTX offers the complete solution to telephone interfacing for broadcast applications, and is configurable to meet many different needs.
In its simplest form, the DTX consists of one digital hybrid with four external lines and an announcer's desk interface, while its maximum size is four expanded digital hybrids, 24 external lines and four studio interfaces.
The system includes simple self-explanatory panels, with most of the functions being implied by the layout of controls and their colours.
For the more complex shows, the comprehensive DTX7004 panel allows the announcer to answer the calls, vet them and if appropriate, route them to the electronic call stacker. At all times the announcer can communicate with the callers using the audio mixers integrated talkback system, without the need to revert to a telephone handset.
Particularly relevent to Competition phone-in programmes, all switching and operational controls are double buffered to the external world allowing the presenter to rotate/switch through calls without the need to close faders making the end programme appear slicker and faster to the users.
The DTX can be directly connected to the telephone network, or in larger systems can be interfaced to the customers PABX.
