2 Safety Notes

The units (matrix router DRM-882LAN and
control panels DRM-882WP/-882WPX) cor-
respond to all relevant directives of the EU
and are therefore marked with
WARNING The DRM-882LAN uses dan-
gerous mains voltage . Leave
servicing to skilled personnel
only and do not insert any-
thing into the air vents! In-
expert handling of the unit
may result in electric shock .
• The units are suitable for indoor use only .
Protect them against dripping water, splash
water and high air humidity . The admissible
ambient temperature range is 0 – 40 °C .
• Do not place any vessel filled with liquid
on the DRM-882LAN, e . g . a drinking glass .
• The heat generated inside the DRM-882LAN
must be dissipated by air circulation; never
cover the air vents of the housing .
• Do not operate the units and immedi-
ately disconnect the DRM-882LAN from
the power supply
1 . if a unit or the mains cable is visibly dam-
aged,
2 . if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
3 . if malfunctions occur .
In any case the units must be repaired by
skilled personnel .
• Never pull the mains cable to disconnect
the mains plug from the socket; always
seize the plug .
• For cleaning only use a dry, soft cloth; never
use water or chemicals .
No guarantee claims for the units and no
•
liability for any resulting personal or ma-
terial damage will be accepted if the units
are used for other purposes than originally
intended, if they are not correctly connect-
ed or operated, or if they are not repaired
in an expert way .
If the units are to be put out of oper-
ation definitively, take them to a local
recycling plant for a disposal which
is not harmful to the environment .

3 Applications

The DRM-882LAN is a digital audio matrix
router with eight analog inputs . The signals
of the inputs can be mixed to eight analog
outputs as desired . The DRM-882LAN can be
used in a wide range of applications, e . g . as a
link between different signal sources and the
amplifiers of a PA system, for multi-zone PA
applications or in rooms with varying PA sit-
uations . Various DSP functions such as equal-
izers, noise gates, delays, feedback suppres-
sion, compressors and limiters are available . A
ducking function and an automixer function
are provided to improve speech intelligibility .
In the control of multi-way speaker systems,
the DRM-882LAN can assume the tasks of
the crossover networks .
Ten configurations may be saved on the
.
unit and be retrieved when required: six via
the buttons on the unit, four by external con-
trol via the switching inputs . In addition, four
all-purpose switching outputs are available .
The software supplied with the unit
allows the user to comfortably set up the
DRM-882LAN via a computer and to operate
it by remote control . The computer is con-
nected via the USB interface, Ethernet or a
RS-485 data bus . With the RS-485 data bus,
up to 64 units can be controlled; and with
Ethernet even considerably more .
The following adjustments can be made for
each input channel:
– gain with 0 dB bypass option
– microphone / line switchover
– signal type balanced / unbalanced
– option to link a channel with its adjacent
channel (stereo mode)
– feedback suppression (frequency shift feed-
back eliminator)
– noise gate
– high pass filter or low pass filter
– parametric equalizer with 3 filters
(for each filter, 3 filter types are available)
– phase reversal
– muting
The following adjustments can be made for
each output channel:
– assignment to one input signal or to the
mixed signal of multiple inputs
– high pass filter and low pass filter with
8 filter characteristics of different slopes,
e . g . for creating crossover networks
– parametric equalizer with 5 filters
(for each filter, 3 filter types are available)
– delay [max . 381 ms], to be entered as time
(ms) or distance (m)
– compressor
– gain [−127 ... +18 dB]
with 0 dB bypass option
– peak limiter [−30 ... +18 dBu]
– phase reversal
– muting
3.1 Control panels
The wall-mount control panels DRM-882WP
and DRM-882WPX are separately available as
optional accessories .
The control panel DRM-882WP can be used
to retrieve the first four configurations saved
in the router and to change the overall vol-
ume . The control panel can be locked by a
key switch .
The control panel DRM-882WPX provides
two operating modes with the following op-
tions:
Master mode
– retrieval of the first six configurations saved
in the router
– change of the overall volume
– change of the volume at the inputs and
outputs
– muting of inputs and outputs
– change of input assignment to outputs and
change of the signal mix ratio
– lock option for the control panel
– automatic deactivation of the display
Zone mode
– change of input assignment to an output
defined by the installer and change of the
signal mixing ratio for this output
– change of volume and muting of the out-
puts
– lock option for the control panel
– automatic deactivation of the display
4 Setting up and
Connecting the Unit
The DRM-882LAN is designed for rack mount-
ing (482 mm / 19") but it can also be used as
a tabletop unit . For rack installation, 1 RS is
required (RS = rack space = 44 .45 mm) .
Prior to connecting or changing existing con-
nections, switch off the DRM-882LAN and the
units to be connected .
