SONIC ULTRAMIZER SU9920
Figure 3.2: The SU9920 in Studio mode
3.1.3 Stage operation with instrument amplifiers
Besides being ideal for use with stereo signals, the SONIC
ULTRAMIZER is also suitable for use with one or two individual
signals, e.g. guitars. With electric guitars it can be used in
combination with a combo amp or a separate modelling
processor-amplifier combination to give the guitar sound more
presence, fullness and punch. A similar combination with a
keyboard and an external amplifier is possible. Because the
two channels of the SU9920 work independently, even two
different mono signals can be processed.
Connect the SU9920 with the effects loop connections on your
combo amplifier if it provides for connection in insert mode, i.e.
exclusively reproduces the output signal of the SU9920 via the
loudspeaker.
If you are using a modelling processor you must connect the
processor output to the SU9920 input and route the SU9920
signal to the amplifier.

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
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
on the SU9920
either does not light up at all or for a short period of time
only.
4) Turn the PROCESS control
until the desired
enhancement effect in the high-frequency range is achieved
or the 0dBU LED in the level display
lights up
continuously.
5) Turn the LOW CONTOUR control
until the desired
enhancement effect in the low-frequency range is achieved
or the 0dBu LED in the level display
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.
