6 SONIC ULTRAMIZER SU9920 User Manual 2.2 Rear panel (8) (7) (9) Fig. 2.2: Control elements on the rear panel (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. 3.1.1 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. B1220 PRO B1220 PRO 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.
