Version XJU-d05

The d05 digital signal processor was specially designed for digital dynamics processing of audio signals before broadcasting. The output level can be limited transparently without affecting the pre-emphasis usually applied to FM transmission systems.

• increased signal density and loudness without side effects
• complex program-controlled level algorithms
• 4 program types: Universal, Classic, Pop, Speech
• digital pre-emphasis filter (50 µs, 75 µs, or J.17)
• digital audio compressor/limiter
• audio-signal limiting without pre-emphasis affection
• optimized modulation using Adaptive Spectral Processing
• stereo or dual modes
• controlled from NEXUS

Signal processing inside – NEXUS provides multiple alternatives for that: XJU processor board. The XJU board is available as version with no front panel; these board can be installed behind front panels of other 8-DU boards to save space.

Version XJU-mpx01

The digital limiter mpx01 ensures the audio-signal compliance to existing FM-transmission standards. The module board integrates a peak limiter and a modulation-energy limiter. The control processes are calculated based on the input audio signal. A new algorithm specially developed by Jünger Audio is employed for limiting the mpx power on the basis of the stereo signal. The output level of the mpx01 can be transparently limited with regard to the standard pre-emphasis applied to FM transmission systems. Thanks to the peak limiter and the Adaptive Spectral Processing, the unit provides for increased loudness for a multitude of pre-emphasis settings.

• peak/modulation-energy limiter
• program-dependent control algorithms
• digital audio-limiter for FM transmission
• audio-signal limiting without pre-emphasis affection
• optimized modulation using Adaptive Spectral Processing
• controlled from NEXUS

Version XJU-d01/2 (on request)

The d02 digital dynamics processor is a high-quality compressor/limiter/expander for dynamic processing of analog and digital audio signals in studio applications. The d02 is easy to operate and requires only a few user settings for achieving optimum results; all other parameters needed for accomplishing an inaudible dynamic processing are set and constantly optimized on the basis of the program signal. The processing results in a higher program density and loudness while the program stays free from coloring, pumping, breathing, distortion, or modulation effects.

• digital compressor/limiter/expander
• stereo or dual modes
• controlled from NEXUS
