4.1 Signal sources
Connect line-level signal sources, e . g . the
output of a preamplifier or of a mixer, to the
screw terminals INPUTS CH 1– CH 8 (15) . The
connections are provided for balanced sig-
nals . To connect unbalanced signal sources,
connect the contacts "−" and
Alternatively, connect microphones to
these terminal screws . Use the computer to
configure the respective input as a micro-
phone or line input (
☞
This procedure can also be used to pro-
vide all microphone inputs with a phantom
power supply of 48 V (
this case, only microphones with balanced sig-
nal outputs can be connected . Microphones
with unbalanced outputs may be damaged
by the phantom power supply .
4.2 Amplifiers or other units
Connect the amplifiers, monitoring systems
or other units for further signal process-
ing to the screw terminals LINE OUTPUTS
CH 1– CH 8 (14) .
4.3 External switching signals
Use the four switching inputs to retrieve spe-
cial configurations (extra programs) . Connect
the units that are to be used as switching
units to the screw terminals INPUT PORT (13)
"S1" to "S4" and the corresponding ground
terminals
.
A switching voltage of +5 V is required .
The logic type and the priority between the
four inputs can be configured via the com-
puter (
☞
chapters 6 .15 .2, 6 .15 .3) .
4.4 Units to be controlled
Four switching outputs with a switching volt-
age of +5 V are available for controlling other
units . Connect the switching inputs of these
units to the screw terminals OUTPUT PORT
(12) "S1" to "S4" and the corresponding
ground terminals
.
4.5 Control panel DRM-882WP
The wall-mount control panel DRM-882WP
(separately available as an optional accessory)
can be used to operate the DRM-882LAN
by remote control . Connect the terminals
"485+" and "485−" located on the rear
side of the control panel to the appropriate
contacts of the jack RS-485 IN (10); the pin
configuration is shown in figure 2 . To supply
power to the control panel, connect the ter-
minals "+ 5 V" and "DGND" to a regulated,
unearthed DC voltage source of 5 V (observe
the correct polarity!) .
Note: In order to enable the control panel to estab-
lish a data connection to the DRM-882LAN, only
switch on the power supply for the control panel
when the DRM-882LAN has already been switched
on .
For mounting the control panel, remove the
cover frame . Behind the cover frame, two
mounting holes are located that can be used
to mount the panel on the wall with screws .

4.5.1
To set the control panel DRM-882WP to the
DRM-882LAN:
1) Disconnect the control panel from the
power supply .
2) Keep the buttons UP and DOWN (18)
.
pressed and connect the power supply .
3) When the LEDs next to the buttons UP
and DOWN light up, release the buttons .

4) Keep the button PRESET 3 (16) pressed
until the LED next to the button lights up
(as an alternative, press buttons PRESET 3

and PRESET 4) .
5) Disconnect the control panel from the
power supply and then connect it again .
4.6 Control panel DRM-882WPX
The control panel DRM-882WPX is provided
with a flush-mount housing . Use the terminal
strip on the rear side to connect the control
panel: If required, loosen the two screws of
the front plate and remove the control panel
from the housing .
Fig. 7 Connections of the DRM-882WPX
Connect the RS-485 connections to the corre-
sponding contacts of the jack RS-485 IN (10);
the pin configuration is shown in fig . 2 . The
centre pair of terminals A+/ B− is designed
for connection of another control panel . To
supply power to the control panel, connect
the control panel to a regulated, unearthed
DC voltage source of 12 V (observe the correct
polarity!) .
Note: In order to enable the control panel to estab-
lish a data connection to the DRM-882LAN, only
switch on the power supply for the control panel
when the DRM-882LAN has already been switched
on .
4.6.1
The control panel DRM-882WPX provides two
operating modes (
the operating mode, to set the automatic dis-
play deactivation (standby) and to address
the DMR-882LAN to be operated by remote
control, call up the menu SYSTEM SETUP:
1) Keep the buttons SET (24), ESC (25) and
the rotary knob (23) pressed for approx .
5 seconds . The menu SYSTEM SETUP is
displayed .
2) Make the desired settings according to the
menu structure shown in fig . 8 .
To select the individual menu items, rotate
the knob; to call them up, press the button
SET; to set them, rotate the knob . To con-
firm a changed setting and to exit the cor-
responding menu item, press the button
SET . To exit a menu item without making
any changes, press the button ESC .
