SONIC ULTRAMIZER SU9920
3. PRACTICAL APPLICATION
The SU9920 belongs to the group of psychoacoustic enhancers
which also includes exciters. These devices can enhance the
quality of audio signals.
In contrast to an exciter, the SONIC ULTRAMIZER does not
add any new harmonics to the signal, but rather improves the
signal quality by processing the harmonics in the original
material. Through this action the sound is changed more naturally
than it is through harmonic enhancement with an exciter.
The concept behind the SONIC ULTRAMIZER is based on the
fact that through signal modification (as is caused for example,
by equalizers and frequency filters), the original signal is
distorted. Through this the time-based sequence of the
fundamental tone and the harmonics, whose correlation is
extremely important for naturally sounding signal reproduction
via loudspeakers, is shifted. Restoring the original time-based
relationships between the fundamental tone and the harmonics
thus ideally leads to optimal reproduction of the original signal
and hence a sound which is free from unpleasant distortion.
With the SU9920 you can reproduce the original relationships
between the fundamental tone and the harmonics and
additionally boost the high and low-frequency portions
independently of each other. Through this the transparency of
the starting signal is greatly increased and a precise reproduction
of all signals over the entire frequency spectrum is obtained.
3.1 Application examples
Similarly to a compressor or a graphic equalizer, the SU9920 is
integrated into the signal path, i.e. connected in series to mix
outputs or integrated into the insert path of a mixing console.
Avoid parallel use in the Aux path, as with an effects unit, since
this mixes the original signal with the processed effect signal,
thereby considerably worsening the sound characteristics.
The best way to use the SONIC ULTRAMIZER is in a signal
chain, e.g. from keyboard to SU9920 to amplifier, as the following
application examples show.
3.1.1 Live sound
The SU9920 is ideally suited to use with live sound systems in
clubs, discos, live concerts and public performances. Here the
unit not only can considerably improve the signal quality, but
also can compensate for the inadequacies of small or weak PA
systems.
For this application the unit should be installed between the
mixing console mix output and the amplifier input. If a graphic
equalizer is also used, it should be positioned after the SU9920.
Because this application involves stereo processing, channels
1 and 2 must have the same settings. Otherwise, the original
stereo image will be distorted.

3.1.2 Studio application
In a studio environment the SONIC ULTRAMIZER is ideal for
mastering to enhance the sound of recordings. The SU9920
can lend your music the professional polish of high-quality
productions in just a few steps. Even if you primarily work with a
digital audio workstation, you can perform the final mastering
with the SU9920 and an external recorder.
For this application connect the SU9920 so that it comes before
the mastering recorder. Channels 1 and 2 must have the same
settings since this application involves stereo processing.
Otherwise, the original stereo image will be distorted.
