There is provision for push button selection of up to 99 TV channels, withelectronic tuning.

The 1U 19" unit provides a high quality video output, balanced linelevel dual channel analogue outputs, balanced line level mono FM outputs and anAES/EBU output.

An LCD display shows the channel selected from memory, the actual channelnumber tuned to, the channel frequency, the audio mode (i.e. stereo, mono FMetc.), and the bit error rate.

A facility is provided to adjust the bit error rate threshold at which theaudio mode reverts to mono FM.

If the stereo signal is present it is decoded and fed to the main outputs.The mono analogue signal can be selected manually if required. When the stereosignal is not present the mono analogue audio channel is routed to the output.If dual language programmes are transmitted as dual channels, either channel canbe selected or both received simultaneously.
