An  asterisk (*)  beneath  the  preset  name  means  that  the  preset  has  been
modified  using  the  audio  settings.  When  a  new  preset  is  loaded,  all  the
changes made in the AUDIO Menu will be reverted.

4.4.1. Gain Menu

Inside the Gain menu, the Main input gain may be modified. Press OK to start editing
the Main Gain. The cursor will blink to show that the value is being edited. Use the
Circular key to modify the value.

The gain can be adjusted b3dB and -6dB. The current values is displayed
on the right side of the display (in dB).

When changing the Main Gain settings, the actual sensitivity of the system
is being changed too. When setting the value to +3dB, the input sensitivity
will be reduced by 3dB (from n8dBu to +5dBu).

4.4.2. Limiter Menu

In the Limiter Menu, it is possible to modify the Threshold setting of the internal DSP
peak  limiter.  Press  OK  to  start editing  the THRESH value  (left  bar).  The  cursor  will
blink to show that the value is being edited. Use the Circular key to modify the value,
and press OK to finish editing.

The level bars TH, GR and OUT provide additional information when an input signal
is connected to the device.

TH  (Threshold):  Shows  the  actual  value  of  the  limiter  threshold  (cursor).
Additionally,  the  bar  will  display  the  input  level.  The  level  of  the  threshold  in
dB is also displayed next to the bar in figures.

GR (Gain Reduction): This bar shows when the limiter is active (the threshold
value  is  being exceeded by  the  input  level).  The  gain  reduction  level  will
display as an inverted VU bar (see Fig. 13, right).
