Junger Audio d07 - Digital Transmission Processor - Manual (Page 7)

A 1 –Function description
FUNCTIONAL DESCRIPTION
The mature technology of the digital transmission processor d07
has now been supplemented by the Level Magic™. The d07 is
originally designed for optimised levelling of program signals for
FM broadcast and TV transmission and reliable protection of
transmission paths against overload at the output of studios, OB
vans as well as satellite up-links. The device operates fully
digitally and, beside AES/EBU interface, it makes use of high end
24bit A/D converters so that digital dynamic processing is
possible for analog as well as digital signals.
Besides the previous levelling by means of an AGC, Compressor
and Peak-Limiter referring to the peak- level for achieving the
maximum loudness and energy of the signal, it’s now possible to
use the more signal wave adaptive new technology of the Level
Magic™ with two reference levels: An Operating-Level for signal
processing by the AGC and the Transient processor and the peak-
Level for the Brickwall-Limiter.
In both operating methods you can factor the adaptive pre-
emphasis, the maximum value for the peak frequency deviation
and the MPX-Limiter into levelling of the signal (see application
notes).
The dynamic range processor principles developed by Junger
Audio enable level managing devices like compressors, AGC
and limiters to be produced with exceptionally high audio quality,
without coloration, pumping, breathing, distortion or modulation
effects sometimes associated with this type of processor.
In short, almost inaudible processing - with ease of use. The
outstanding quality of the processing is based on the Multi-Loop
dynamic range control principle in combination with adaptive
controlled processing algorithms developed by Junger Audio.
The unit is easy to operate and requires only a limited number of
settings to be made by the user to achieve optimum results. All
other parameters necessary for inaudible processing are
continuously automatically controlled in response to changes in
the programme signal.
