Stereo Mastering Dynamics Processor U796M2 - 3-Slot / Triple-Wide Version
V700 Mastering Modules
Stereo Mastering Prozessor Home | V700 Mastering Home
The Stereo Mastering Dynamics Processor is available in different versions, which have different control ranges and configurations of particular functions. In
addition, the color of the faceplate and the control knobs can be determined by the customer. Therefore, the appearacne can be different from the the graphics
below. The feature set is identical with all these versions. The modules are available in balanced, grounded (eletronically balanced), and balanced, floating
(transformer balanced) versions. Both versions can be selected for inputs and outputs independently.
The U796 Mastering Dynamics Processor is available in 3 versions, U796M1, U796M2 and the 3-slot version of the U796M2. This page refers to the standard, 2
slot versions U796M2. The 3-slot version is almost identical; however, some additional functions are exisiting. The 2-slot version is here . The U796M is here .

Control Elements Notes and
Pecularities
1 Limiter Threshold
sets the threshold of the limiter section between - 6 and
+ 18 dB
The Limiter
is an
independent
section. The
limiter input
is driven
from the
compressor
output. It is
located
directly pre
the output
drivers of
the dynamics
processor.
2 Limiter Release
modifies the limiter release time from 50 ms to 2.5 sec
3 Limiter Attack
Attack time variation from 20 µsec to 6 ms. With the
minimum attack time the second half wave of a 20 kHz
signal is regulated down to threshold. The longer
settings are only important when using the limiter as
additional compressor section.
4 Limiter Ratio
If an external limiter, like the Mastering Peak Limiter with
Delay U795 is used, the limiter section of the U796 can
be used as additional, independent compressor stage.
The ratio control is only meaningful, if the limiter is used
as compressor.
With Limiter
Operation
the Ratio
contol has
to be set all
to the right!
5 Output Gain
The output gain control only affects the output level but
not the limiter and/or compressor settings. It has a
control range of +/- 10 dB. Output gain is usually
switched on and off together with the limiter.
5a The GAIN Switch activates the Output Gain Control,
independent of the Limiter. If GAIN is not pressed, it will
be activated if the Limiter is switched on (6)
6 The LIM Switch activates the Limiter
7 Compressor Threshold Control
Controls the threshold level of the compressor section in
the range from -32 dBr to + 15 dBr (0 dBr = + 6 dBu ~ +
4 dBV)
8 Crest Switch
The Crest Switch changes the operation mode of the
ac/dc converter from peak (PK) to RMS in 6 steps. Peak
causes a fast and hard regulation with high density,
while RMS results in a soft, loudness related regulation.
The other positions select carefully choosen values
between the two extremes.
The position
of the Crest
switch
determines
the basic
character of
the
compressor.
9 Knee Control
changes the transition from the unregulated range below
threshold to the regulated range above threshold from
hard (0 dB) to soft (20 dB). With the 20 dB setting the
law that is determined by the ratio setting is reached 20
The lower
the ratio
setting is,
the lower is
