7.3 Device list (Star Network)
In the "Star Network Mode", the configuration window for the inputs
☞
( chapter 7 .6) and on the left of it the list of DRM-884 devices "De-
vice List" will immediately appear . "Searching ..." will appear while
the network is searched for matching devices . Then all devices found
will be listed with their names, IP addresses and MAC addresses . The
number of the devices found ("Count") will be shown at the bottom .
Click to repeat the search .
To configure a device, click the device on the list to select it . The list
will disappear and the current configuration of the device selected will
be loaded . A green field "Status" at the top will indicate connection
to a device . To configure another device, click the icon
on the left to show the list again .

7.4 Matching the network settings

Communication between a computer and DRM-884 is only possible
when both devices are in the same subnet . DRM-884 is preset in
such a way that it will be automatically configured by a DHCP server
in the network, e . g . in a router . If a DHCP server is not available,
DRM-884 can also be configured manually and a fixed IP address can
be assigned to it .
To change the network settings, enter the current IP address of
DRM-884 via a web browser . If you do not know the address, use the
function "Device Scan" (chapter 7 .2) to find the address . The log-in
window will appear:
Fig. 18 Log-in window for network settings
The default log-in details are:
ID = admin, Password = system
It is recommended to change the password later to prevent unauthor-
ized access . The following menu will appear:

It is possible to go to other configuration pages . They are listed on
the left .

7.5 Configuring signal processing

After starting the program in the "Star Network Mode" or after
double-clicking the block of DRM-884 in the view of the device con-
stellation in the "Daisy Chain Mode" (fig . 15), the settings of a DRM-
884 connected will be loaded to the computer and shown in the
view "Input DSP Channel" . To change the view, click the buttons at
the top . A change of settings on the screen will directly affect signal
processing of DRM-884 .
ATTENTION Combined with the control program, the signal pro-

7.5.1 Signal path

Figure 3 on page 2 shows a block diagram of the path a signal takes
through DRM-884 . Starting at the inputs, the signals IN 1 – 8 pass the
adjustable microphone preamplifier first, then the analog-to-digital
converter . The signals of the inputs IN 9 – 12 are already converted in
the extension module . Then the inputs IN 1 – 12 pass the following
stations:
➾ gain (GAIN)
➾ controlled gain reduction of the priority circuit (Ducker)
➾ dynamic expander (EXPANDER/GATE)
➾ signal delay (DELAY)
➾ dynamic compressor (COMPRESSOR)
➾ high-pass filter and low-pass filter (HPF + LPF)
➾ 5-band equalizer (EQ)
➾ phase reversal option (POLARITY)
➾ automatic mixer
Via the matrix, any processed input signals can be assigned to each
output channel . As an alternative, the signals can be routed via the
cessor is an effective tool for making slightest but
also major changes to the transmission properties of
the PA system .
Therefore, any change of parameter should be
carefully considered and be made with the required
expertise . In the worst case, extreme changes of the
settings may damage the speakers .
