The C8082 Module is performing two main tasks:
- Automatic or manual Switch Over or Fail Over in case of input level loss.
- Ducking of a main stereo or surround sound signal by a line level microphone or by a pre recorded announcement / advert input.
It offers different types of Fail/Switch over (5.1 to Stereo, 2xStereo) and similar associations for Ducking (5.1 to C, L&R or L&C&R; and 2xStereo ducking).
The inputs of the C8082 are equipped with level detectors for either detecting a loss of the input or an active source for Ducking. The Fail / Duck detection part performs the logical action depending on the various input statuses and user defined operating modes.
The C8082 provides 4 audio buses for 5.1 or multiple Stereo processing. In the switch over modus, the DSP monitors a certain number of sources, and when detecting an absence of or low input level on one of the targeted sources, the C8082 performs automatically a fail over switching.
6 channel outputs feed the processed signals back to the C8000 frame bus. Each of these 6 outputs has the Junger Brickwall limiter with look ahead function inserted. This limiter not only provides smooth non distortion output in case of an overload but also defines the maximum output level. The algorithms are adaptive to the material so only one parameter, the Limiter Program, is needed to set up this part. For 5.1 or stereo processing the limiters control circuits are automatically linked together for proper multi channel operation.
The C8082 Switch/fail over is particularly useful when using Junger Audio’s integrated Dolby 5.1 processing chain, and receiving Dolby E encoded signals. As a matter of fact Dolby E signals (which are data only) if wrongly encoded by the sending source, won’t provide any proper audio once decoded, and to prevent silence at the output the C8082 automatically switches to the PCM audio of the given contents.
C8082 is part of the C8000 series and as such is entirely monitored and operated via Web interface.
Applications cover mainly broadcast operations especially where Dolby coded signals are used, requiring “guaranteed” output, regardless the type of decoding/encoding processes needed.
About C8000 series
The C8000 is an ensemble of Frames, I/O interfaces and DSPs designed to tailor the different processing requirements of broadcasters according to their exact needs. Pick up the type and amount of input and output interfaces to get your signals into the C8000 frames, select the DSP you need (Loudness control, Shuffling, Delay, various Dynamics processing’s, etc.) and solve your problems easily and adequately. Operation of C8000 series is performed via Web Interface, but also remote controls (hardware and software) offered by Junger Audio or third parties (VSM).
