(1)
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 3 dBu before the signal becomes distorted.
The LED should not light up.
(2)
LEDs: The four LEDs display the output level in 10 dBu steps.
Regular illumination of the 0 dBu LED indicates an optimal output level.
(3)
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 +12 dbU at 5 kHz.
(4)
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
+12 dbU at 50 kHz.
(5)
IN/OUT: With this switch signal processing is activated and deactivated.
The LED lights up in the active operating mode.
(6)
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.
