ULTRA-DYNE PRO DSP9024
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.

3.8 The Exciter function

An additional special feature of the ULTRA-DYNE PRO is its integrated Exciter function. This permits the
addition of supplementary harmonics to your program material. The intensity of the effect can be set with the
Exciter Process parameter in the <TUBE> and <IN/OUT> menus. The Ratio of odd to even harmonics can be
set with the Odd/Even parameter.
The ExciterDrive parameter can be found in the band menus of the upper three bands. Use this parameter to
determine the share of each of the three upper bands to be processed by the Exciter. The result is a multiband
Exciter tailored precisely to your tastes, offering the most perfect audio enhancement possible.

3.8.1 Audio enhancement during the copying process

Even under the most favorable conditions, program material loses some of its presence, life and clarity with
each copy operation. These losses are especially conspicuous when copying cassettes with the noise reduc-
tion enabled.
The use of the ULTRA-DYNE PRO Exciter can help minimize or compensate for these copying losses. When
copying a high-quality, low-noise source, it's even possible to produce copies that sound better than the
original with careful application of the ULTRA-DYNE PRO.

3.8.2 Audio enhancement of instruments

The bandwidth of most electronic instruments is limited by their sampling rate. The ULTRA-DYNE PRO can
help synthesizers, samplers and drum machines sound more natural and transparent.
It can also be used to highlight subtleties in the sounds of acoustic instruments such as guitars without
altering the character of the instrument. The punch of percussion instruments such as toms, bass drums, etc.
can be enhanced for more power and impact.
