(7) FUSE HOLDER / IEC POWER SOCKET: The mains connection is made via
an IEC male socket. It complies with relevant safety regulations. A suitable
power cord is included. Replace the fuse with a fuse of the same type.
(8) OUTPUTS 1: Balanced XLR sockets and ¼" jacks - these are used to connect
amplifiers as well as further signal processors and recording devices.
The jacks and XLR sockets can be used in parallel when two outputs
are required.
(9) INPUTS 1: Balanced XLR sockets and ¼" jacks - these are used to connect
line-level signal sources (e.g. a mixing console). To avoid interference only
the jacks or the XLR sockets should be used.
SERIAL NUMBER: The serial number can be found on the back right side of
the unit. It is needed for online registration.

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.
