SONIC ULTRAMIZER SU9920
2. CONTROL ELEMENTS AND CONNECTIONS
CLIP:
This LED is constantly lit when the input level is too
high. If it lights up for a short period of time it is warning
you of an impending overdrive. There is a safety headroom
of 3dBu before the signal becomes distorted. The LED
should not light up.
LEDs:
The four LEDs display the output level in 10dBu
steps. Regular illumination of the 0dBu LED indicates an
optimal output level.
PROCESS:
With this control the portion of high-frequency
signals to be processed by the SU9920 is specified. The
MAX setting corresponds to a level boost of +12dbU at
5kHz.
LOW CONTOUR:
This control adjusts the portion of low-
frequency signals to be processed by the SU9920. The
MAX setting corresponds to a level boost of +12dbU at
50kHz.
IN/OUT:
With this switch signal processing is activated
and deactivated. The LED lights up in the active operating
mode.
POWER:
Use the POWER switch to put the unit into
operation. The POWER switch should be in the "Off"
position when you connect the unit to the power feed
(mains).
To disconnect the unit from the mains, pull out the power plug.
When switching on the unit ensure that the power plug is easily
accessible. To mount the unit in a rack ensure that the unit can
easily be disconnected from the mains by means of a plug or an
all-pole mains switch on the back side.
Please note: Switching the POWER switch off does
not disconnect the unit completely from the mains. For
this reason you should unplug the power cord if the
unit is not going to be used for prolonged periods of
time.
2. CONTROL ELEMENTS AND CONNECTIONS

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.
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.
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.
