SONIC ULTRAMIZER SU9920 User Manual
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:
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
(5)
on the SU9920 is illuminated, i.e. that the unit is working
and all controls are set to ‘MIN’.
◊
First make the following settings for one channel (channel 1 or 2)
according to the input assignment. For stereo applications choose
the same settings for the second channel as those made for the
first channel.
3) Set the signal level on the device feeding the SONIC ULTRAMIZER such that
the CLIP LED
(1)
on the SU9920 either does not light up at all or for a short
period of time only.
4) Turn the PROCESS control
(3)
until the desired enhancement effect in the
high-frequency range is achieved or the 0 dBU LED in the level display
(2)
lights up continuously.
5) Turn the LOW CONTOUR control
(4)
until the desired enhancement effect
in the low-frequency range is achieved or the 0 dBu LED in the level display
(2)
lights up continuously.
6) To compare the original and processed signals, repeatedly press the
IN/OUT button.
7) Repeat steps 4) to 6) until you are satisfied with the result.
4. Installation
4.1 Rack mounting
The BEHRINGER SONIC ULTRAMIZER SU9920 requires 1U for installation in
a 19-inch rack. Please make sure that you leave around 10 cm for the rear
connections. For installation of the unit in a rack please use M6 machine
screws and nuts.
4.2 Audio connections
There are various ways to integrate the SU9920 into your setup. Depending on
the application you will need different connecting cables, and these will be
discussed in the following section.
4.2.1 Cabling with jack cables
To operate the SU9920 in series with other equipment, you will need standard
commercial ¼" jack cables, often referred to as instrument cables or patch cables.
These cables have a ¼" TS jack plug at each end. Connect the inputs of the
equipment with the corresponding outputs of each of the other devices.

If your other equipment has balanced inputs, use a balanced switched cable
with two stereo jack plugs at the balanced outputs of the SU9920. These cables
provide a high level of security against interference signals such as noise
interference from power cables, and they should be used for all long cable routes.
