The config page of the channels input section holds control elements necesarry
to set the channels input levels :
1
2
If the channels source selection is a Mic source, then these three elements are
provided on the left side of the page.
[1]
48V
Switches phantom power (48V) to the microphone on and off.
[2]
Highpass filter
Activates a highpass filter on the analog side of the microphone input, before
the A/D converter. This can be useful to filter out rumbling noise on speach
signals. The cutoff frequency of this filter is fixed at 75Hz and it has a slope
of 12dB/oct.

Mic gain
This fader sets the microphone gain.The gain range is 86dB and the absolute
numbers on the fader-scale are depending on the
Max Level
of the analog
I/O.
Max Level
is defined in the Settings page.
On channels with Line inputs as source, other control elements are displayed
in place of the Mic control elements.
Max Level
The
Max Level
setting defines the systems reference line level for 0dBFS.
This is a global setting found on the Settings-page. But it can also be set on
a channel by channel basis. This setting needs to correspond with the actual
level calibration of the analogue input- and output interfaces. As a standard,
the Micro Core is shipped with all analogue levels calibrated to +9dBu. This
means that the highest possible analog signal that leaves the mixer is +9dBu.
And it also means, that signals which are higher than +9dBu will clip the A/D
converters.
Then, in the second section of this page, the control elements of the digital
