Peak Limiter Release Time:
When the signal falls below the Limiter Threshold, the gain reduction is returned to zero. The release time
determines the speed at which the signal is returned to its original level.

Tab. 3.3: Basic settings of the Peak Limiter section
Use the Threshold parameter of the Peak Limiter to set a level that will protect downstream devices from
overload. If the LIM warning on the advanced level meter lights up frequently or continuously, reduce the
Threshold slowly toward the 0 dB position.
Because fast level changes are more noticeable than slow changes, long release times are used where
unobtrusive signal processing is required. In some situations such as live operation in which the ULTRA-
DYNE PRO is used for the final processing of the main mixer output signal, the principal goal is to protect
devices such as speakers and power amplifiers from short-term overloads. In those cases a short release time
is more appropriate to ensure that the Limiter only intervenes when it is needed and the level returns to normal
as soon as possible. Long release times are better suited when the Limiter should remain inaudible, for
instance in broadcasting, quiet club environments or when a signal is transferred to tape.
3.7 Tube simulation
The BEHRINGER ULTRA-DYNE PRO features a newly-developed Tube Emulation which generates harmonics
for additional warmth and punch in your material. This Simulation is intended more as a subtle sound enhance-
ment and not primarily as an effects processor. Four different tube types commonly used in preamplifier and
power amplifier circuits are available. The intensity of the effect can be controlled with the TUBE Process
parameter.
3.7.1 Application
The ULTRA-DYNE PRO Tube Simulation is a subtle audio processing option to add polish to your compressed
and limited signal. Increasing the Tube Process parameter gives the signal a lively, warm character.
In many cases, highly compressed audio signals suffer a loss of presence and sparkle. The Tube Emulation of
the ULTRA-DYNE PRO counteracts this effect and adds life to the material. It can add punch to percussion
instruments, for example. The clarity of instrument sounds which are rich in harmonics by nature can also be
enhanced. Overall, the input material gains fullness and brilliance. A better separation in the low-frequency
range contributes to the clear acoustic location of individual instruments. Thanks to the Tube Simulation,
vocals gain in presence and volume without becoming obtrusive, facilitating their integration in the mix. The
natural quality of synthetic sounds is enhanced; especially guitar sounds from MIDI expanders gain in realism
when processed by the ULTRA-DYNE PRO. This contributes actively to the quality and subtlety of the mix.
The design of the Tube Simulation is strongly oriented toward musical applications.
