Gain
Control
When
the
gain
control
is
at
its
maximum
position,
the
maximum
input
voltage
before
clipping
is
5Vrms
(+/-
7V
peak).
This
value
increases
proportionally
by
turning
back
the
gain
control.
In
the
12
o’clock
position,
the
input
signal
is
reduced
by
6dB.
Therefore
the
maximum
input
voltage
before
clipping
increases
to
10Vrms
(+/-
14V
peak)
accordingly.
The
Gain
Control
is
located
in
the
upper
middle
of
the
DSP
Control
Panel:
2.2.1.4.

Caution:
The mains POWERCON connectors are not suitable for powering up or down the system and
so should not be plugged or unplugged while under voltage! Always connect the POWERCON plug
FIRST, THEN connect the Schuko plug (or other Standard 3 Pin Power Plug) to the AC power
socket
.
Follow these steps in a reverse order to power
down the system!
R
CAUTION!
Caution:
+/-
15Vpeak (~+22dBu) at the input shouldn’t to be exceeded under any circumstances!
