1 Operating Elements and
Connections
1.1 Front panel
1 LED PHANTOM POWER; lights up when the
phantom power supply for the microphone
inputs is switched on
2 LC display
3 Buttons PRESET 1 – 6 for retrieving the con-
figurations previously saved
To call up the system setting menu, keep but-
ton 5 pressed for several seconds. The func-
tions of the system setting buttons are
described in chapter 5.3.
4 Status LEDs for the input/output channels
CH 1 – CH 8
LIMITER – limiter or compressor active
CLIP – input overloaded (after EQ)
SIGNAL – signal for output signal available
FBK – feedback suppression active
MIC – input for microphone
LINE – input for line signal source
5 USB jack, type B, to connect a computer for
remote control and for configuration of the
DRM-880LAN
1.2 Rear panel
6 POWER switch
7 Mains jack for connection to a socket (230 V~/
50 Hz) via the mains cable supplied
8 Support for the mains fuse;
always replace a blown fuse by a fuse of the
same type
9 RJ45 jack TCP/IP to connect a computer for
remote-controlled operation of the DRM-
880LAN via Ethernet; the two LEDs above
the jack indicate that the connection is being
established or that data is being transferred
10 RJ45 jack RS485 IN to connect a computer
for remote-controlled operation or to connect
the remote-control panel DRM-880WP (fig. 3)
11 RJ45 jack RS485 OUT to connect an addi-
tional unit to be remote-controlled by the
computer that is connected to jack RS485 IN
(10)
12 Switching outputs S1 – S4 as screw termi-
nals*
13 Switching inputs S1 – S4 as screw terminals*
to retrieve the extra configurations previously
saved
14 Balanced audio signal outputs CH 1 – CH 8
as screw terminals*
15 Balanced audio signal inputs CH 1 – CH 8 as
screw terminals*
* For easier connection, the entire terminal block may
be removed from the unit.
