[. . . ] SU9920 User Manual Version 1. 0 April 2007 SONIC ULTRAMIZER SONIC ULTRAMIZER SU9920 IMPORTANT SAFETY INSTRUCTIONS 14) Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. CAUTION: To reduce the risk of electric shock, do not remove the top cover (or the rear section). WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain and moisture. The apparatus shall not be exposed to dripping or splashing liquids and no objects filled with liquids, such as vases, shall be placed on the apparatus. [. . . ] LOW CONTOUR: This control adjusts the portion of lowfrequency signals to be processed by the SU9920. IN/OUT: With this switch signal processing is activated and deactivated. The POWER switch should be in the "Off" position when you connect the unit to the power feed (mains). 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. 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. Figure 3. 1: Use of the SU9920 with live sound systems 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. PRACTICAL APPLICATION 7 SONIC ULTRAMIZER SU9920 Figure 3. 3: The SU9920 in use with guitar amplifiers 3. 2 Basic operation Due to the small number of control elements on the SU9920 it is easy to learn to use it. Perform the following steps: Figure 3. 2: The SU9920 in Studio mode 1) Connect the unit according to the application as described in section 3. 1. 2) Switch on all devices (amplifier and loudspeaker last) and ensure that the IN/OUT switch on the SU9920 is illuminated, i. e.
