These keys allow to mute the output signal of the corresponding output channels. Pressing a key
once switches the mute-function ON; the key’s red LED lights. Pressing the button again switches
the mute-function OFF; the key’s LED is dimmed again.
These LEDs indicate the peak level of the corresponding outputs. The Dx38 should be operated in a
range, so that the clip-LEDs are not lit. Otherwise, this could lead to internal clipping. The COMP/
LIMIT-LEDs light, when the compressor / limiter of the corresponding channel is activated; e. g.:
when the audio signal level exceeded the previously set threshold and therefore the output level is
compressed or limited.
These controls are used to set the output levels of channels 1 to 4, allowing to match the Dx38 to
the input levels of the devices chained in sequence. Correctly setting these controls results in an
improved S/N ratio. In most cases, good results are achieved when setting the controls to "-6". The
digital output gain control should be used when higher output levels are needed. Use the controls
OUT 1 - 4 to attenuate the output levels. It is not recommended to use the digital output gain
control for massive attenuation, since this would decline the dynamic range of the D/ A-converters.

Clicking on the DSP button opens the Setup & Control window, which provides access to all DSP
and speaker parameters.
DSP
The DSP pages provide overview and access to all DSP parameters of the sound system processor. Within this window
you can use the Flow Diagram Selector to link to different function groups.
FLOW DIAGRAM SELECTOR
The Flow Diagram Selector can be accessed from any DSP page offering navigation means within the DSP signal
processing functions. The Flow Diagram Selector lets you select different function blocks, where the actually selected
block is displayed in a yellow engaged field.
A short description of each DSP page is provided in the following table. Please refer to the corresponding chapters for
a more detailed explanation.
Element Description
FLOW DIAGRAM The signal flow display provides an overview of an amplifier’s DSP settings. This
area also includes all controls for the preset location/file management,
configuration settings and RACE file import.
MASTER EQ The MASTER EQ page provides access to the two 5-band parametric equalizers of
the sound system processor inputs.
