1. To prevent the risk of fire and shock hazard, do not expose any appliance or module high humidity or water.
2. Make sure that no alien objects enter the appliances or get in contact with the modules –especially no metal
parts –since this would very likely cause dangerous electric shock and/or malfunctioning. There are no
user-serviceable parts located inside the appliances or on the modules. Opening appliance enclosures
and/or rack shelf systems can lead to dangerous shock hazard. Do not open or try to reach inside the
enclosures of appliances. Leave installation, servicing, maintenance, and any other works on the appliances
or the rack shelf system to qualified service personnel only.
3. When exposing appliances/modules to extreme temperature changes, i. e. when moving them from the
outside into a warm room, condensation may occur. If so, it is necessary to wait before use until the devices
gained room temperature.
4. Under no circumstance place any liquid-containing cans, glasses, mugs, etc. on top of an enclosure. In case
any liquids or foreign obstacles entered the enclosure of an appliance, immediately unplug the device from
the mains supply and have it serviced.
5. Make sure that appliances/modules are always provided with sufficient ventilation. Do not expose devices to
direct sunlight or any other heat-radiating source.
6. Do not expose appliances/modules to extreme dust or humidity. Operating the system under environmental
conditions like these can lead to severe damage through fire or cause bodily harm to the operator.
7. Make sure that the stated mains voltage is in accordance to the specifications of your mains supplier.
Mismatching will cause severe damage to all appliances/modules.
8. Make sure that mains cords and/or any other cabling are not damaged or being jammed by the turning
frame or any other movable parts of the rack shelf. Damaged cables can lead to fire hazard and/or can be
the cause for electric shock.
9. The mains cord of the rack shelf installation is supplied with a 3-pole plug to minimize the risk of electric
shock. It should only be connected to a grounded wall outlet. Under no circumstances insulate the ground
contact. When using an extension cord, always use a 3-pole grounded cable. When using multi-outlets for
distributing, make sure that the wall outlet's capacity is not exceeded, since this could lead to fire hazard
and/or can be the cause for electric shock.
10. The DPM 4000 contains a lithium-type battery to provide the internal clock with power. The lifetime of this
battery-type spans approximately 10 years. When the battery's voltage drops below a certain minimum, an
according message appears on the paging station display. In this case, the battery has to be exchanged by
an EVI Audio GmbH authorized service technician. Under no circumstances try to exchange the battery
yourself!
CAUTION! There is a severe risk of explosion when incorrectly exchanging the battery. Only replace
with the same type of battery or one especially recommended by the manufacturer. For
environmental awareness: Take care of used batteries following the manufacturer's advice.
11. Obeying the VDE-regulation DIN VDE 0800 is necessary when installing and operating 100V-loudspeaker
systems. Especially with 100V-loudspeaker systems that are part of an emergency alert installation,
protection measures have to be in accordance with safety class 3 regulations.
CAUTION! During operation, speaker group connectors (POWER OUTPUT) may carry shock hazard
output voltages (>34V peak value). Thus, the installation of the connected loudspeaker
groups has to in accordance to security standards and regulations as stated above.

3. System Description
This chapter provides an overview of the general configuration of the PROMATRIX system and its most important
functions. The following block diagram shows a typical PROMATRIX system installation including the DPM 4000
central unit, paging stations, audio equipment, amplifiers, power supply unit, relay board assemblies, loudspeaker
lines, and control board assemblies for external signals.
figure 3.1 PROMATRIX System
3.1 General Overview
The digital PROMATRIX manager DPM 4000 represents the central unit of the system. It is used to control and
monitor all connected components via several serial interfaces. The chapter Single Device Descriptions contains
all necessary information about the DPM 4000 and its available modules.
The kind and amount of connected audio sound sources, amplifiers, and relay board assemblies are extremely
variable. This allows configuring the system to basically match any requirement. The system is capable of
managing up to 16 paging stations and up to 100 output lines. More than 150 control inputs and outputs are
available for controlling and monitoring purposes providing the possibility to generate and manage logic levels
and analog levels as well. For detailed information, please refer to the chapter DCS 400 Control System.
Configuration and documentation of a PROMATRIX system installation is established through the use of the
PROMATRIX Designer software –a comfortable graphical user interface that runs on a PC under Windows
95/98/NT. This allows changing the system’s setup at any time to meet new requirements, without the need to
alter the actual installation. The PC has to be connected to the system only when loading or changing its
configuration. During normal operation, PC-interaction is not necessary. Anyway, in most cases the permanent
connection of a computer bears benefits, like displaying detailed status reports or the printing of protocols. It also
offers the possibility for remote diagnosis and remote maintenance via modem.

SYSTEM DESCRIPTION
3-2PROMATRIX System User Handbook 1.1
3.2 Audio Routing
The DPM 4000 employs a digital audio matrix providing 4 inputs and 4 outputs. Additional matrix junctions for the
integrated gong and alarm signal generators, the vocal recording/playback unit, and the lock-on of the pilot tone
and its evaluation are incorporated. All input signals and internally generated signals can be freely mixed inside
the matrix and outputted through the 4 amplifier channels. Routing speaker lines to these amplifier channels is
achieved via the relay-matrix, which offers up to four separate audio buses simultaneously, while the DPM 4000
takes over the management of all these signals according to their priority.
Next to connecting paging stations, the audio inputs also serve for the connection of other audio sound sources,
like microphones, mixers, CD-players, cassette decks and DAT-recorders, tuners, etc. Several different input
modules are available to optimally adjust and match signal levels and connections.
3.3 Volume And Tone Controls / Delays
The PROMATRIX system provides individual volume controls for each input, output, and paging station. Even the
internal audio sources, like gong/alarm tone generators, voice message playback, and pilot tone generator
employ individual level controls, each. Additionally, it is possible to set an attenuation that unanimously affects the
inputs. This value determines the degree, by which the input signal is attenuated during the reproduction of
messages or other signals with a higher priority setting. This allows to smoothly fade-out and fade-in background
music during the transmission of important messages.
Besides, each of the four inputs embodies three fully parametric digital filters allowing for optimal tone control.
The filters provide different filter types like Hi-/Lo pass filters, shelving filters, and peak-dip-filters providing the
possibility for adjusting the sound within the entire audio transmission range. Factory-preset filter settings for the
DPC 4000 Series paging stations are already provided.
Setting volume levels and filter parameters is accomplished via PC during the configuration procedure. Further, it
is possible to alter any volume setting during the later operation of the system via special-function keys on the
paging stations or through external controls that are connected to analog or digital control inputs.
All four outputs employ digital delays allowing signal delays of up to 330 ms per channel. Natural delays, resulting
from loudspeaker positioning which causes time differences in the traveling of sonic events or environmental
circumstances related to architectural characteristics of the location, can be equalized without additional effort.
3.4 Signal Generators / Voice Message Memory
The DPM 4000 provides a variety of tone generators for the generation of gong, alarm, and text signals. Signal
generation is realized through DSP-algorithms, which are extremely flexible in use, so that they can be adjusted
to match nearly any possible application. Factory presets include 6 different gong signals, 18 different alarm
signals, plus sine cycle at any frequency. Other than in comparable equipment, the PROMATRIX signal
generating DSP-algorithms do not take up any extra storage of the voice message memory.
In addition, a voice message recording/playback module providing CD-quality sound is optionally available. With a
total recording time of approximately 6 minutes, 25 different messages are being managed. The DPM 4000
provides the possibility to install up to four optional FLASH-memory modules, depending on individual desires or
requirements.

SYSTEM DESCRIPTION
PROMATRIX System User Handbook 1.1 3-3
3.5 Paging Stations
The DPC 4000 Series paging consoles are mainly meant for transmitting voice messages and calls but also to
manually control the PROMATRIX system. Available paging station functions are: line/group selection, voice
messages, program assignment, launching gong and alarm signals, and reproduction of voice message memory
announcements. Additionally, special commands include volume control, monitor selection, preset switching,
lighting control, function status indication, etc. Thus, it is possible to configure the paging consoles to serve as
operation panels for general control purposes.
If a voice call is being launched into a speaker line that is already busy with other audio transmissions, the caller
gets a busy-sign, i. e. the BUSY-LED blinks. In case the calling terminal has a higher priority it will interrupt any
messages from other paging stations or audio signals with lower priority levels. Interruption does not take place
uncontrolled anymore. Before actually interrupting a transmission, the blinking LED indicates that a line or group
is busy when selecting a destination, leaving the choice to the operator, whether he/she immediately wants to
interrupt or wait upon the conclusion of the momentary reproduced program.
3.6 Control Inputs And Outputs
By using the control inputs, it is possible to link the PROMATRIX system to fire alert systems, burglary alert
systems, or to a central operating desk. It is also possible to connect external switches, breakers, rotary controls
or rotary encoders, respectively to query control outputs of external units (power supplies, power amplifiers, …).
The control outputs allow switching external devices ON or OFF, trigger signals and events, switch monitor
sources, remote control doors, gates or shutters, generate analog signals for the control of multimedia systems,
etc.
A total of 130 control inputs for logic levels, 128 control inputs for analog levels, 16 inputs for rotary encoders, 127
logic-control outputs, and 128 analog-control outputs are usable.
3.7 Clock / Calendar
The PROMATRIX manager DPM 4000 has an integrated quartz-controlled real-time clock which can be set for
radio-controlled DCF 77 operation using the optional antenna (DCF 77 tuner NRS 90193). The system clock
automatically recognizes leap years and, if in DCF 77 mode, automatically switches between daylight saving time
and standard time.
The system clock provides the possibility to control up to 40 external slave clocks. For this purpose, the DPM
4000 employs a special, short-circuit-proof output for pole changing impulses. Slave clocks are automatically re-
synchronized whenever a time difference to the system clock is detected; like for instance in cases of power
outage or when time values were entered manually.
It is possible to activate pre-set functions like break-gong signals, background music, remotely controlled gates,
switch lights ON/OFF, etc. when using system clock and calendar function together All the functions mentioned
before can be programmed for specific days; but also hourly, daily, weekly, monthly, and yearly activation is
possible. Up to 500 time-controlled events can be programmed.
3.8 Monitoring
The PROMATRIX manager DPM 4000 embodies a monitor amplifier with headphones/speaker output. The
integrated logic-switching circuit provides the opportunity to listen to the signals of any internal input and output.
Assigning external sound sources to the monitor bus is possible as well. This additionally allows monitoring
amplifier outputs or pre-listen to the contents of external voice message memories and other audio devices.
The remote control’s wiring already includes all the cabling necessary for the pre-/post-listen feature when using
remote-controlled amplifiers.
When using the DCS 420 PROMATRIX MONITOR MANAGER, easy programming and operating is available.

SYSTEM DESCRIPTION
3-4PROMATRIX System User Handbook 1.1
3.9 Macros
Macro is defined as the combination of several commands, functions, and their parameters in an internal
consecutive sequence. For example a gong signal with specific volume and priority settings has to be transmitted
in different calling zones, while simultaneously activating a control output. In that case the macro consists of the
functions “gong” and "control" with the parameters gong-type, volume setting, priority number, calling zone
numbers, and the type and id-number of the control output.
It is possible to initiate a macro via the special function keys on the paging consoles or to trigger it via control
input. It is also possible to combine a macro with the internal clock or calendar.
The PROMATRIX system provides a number of pre-programmed macros, where only individual parameters still
have to be entered. Additionally, it is possible to combine several macros in a sequence. Using pre-defined
macros and sequences lets you create new, user-specified and application-related macros, which basically are
capable of managing any control function imaginable. A total of up to 250 user-macros can be programmed.
3.10 Interfaces
Besides its control inputs and control outputs, the PROMATRIX system provides additional interface ports. The
connection of paging consoles to the PROMATRIX manager DPM 4000 is performed via serial RS-485 ports. This
allows connecting up to four terminals at a single port. Power amplifiers and the DCS 400 controller are
connected to another independent RS-485 port, which allows direct management of up to 64 power amplifiers and
8 DCS 401.
Connecting a PC is established via serial RS-232 port on the rear panel of the DPM 4000. It is not necessary for
the PC to be permanently connected to the DPM 4000.
An additional RS 485-interface offers the possibility to operate several DPM 4000 in a network.
3.11 Safety Standards
The PROMATRIX system complies with all applicable requirements of the IEC 849 standard –electro acoustics
emergency alert PA-systems. The digital PROMATRIX manager DPM 4000 guards and monitors its entire
internal functions. All connected paging stations and power amplifiers, including the wiring, are monitored via
polling and pilot tone functions. Using the remote control units in the power amplifiers, it is also possible to
monitor the loudspeaker lines. Of course, the PROMATRIX system is also prepared for operation with emergency
power supply. In case of a power outage, the DPM 4000 takes over the entire power management; i. e. all internal
and external power consuming components are switched to stand-by mode. Only when necessary, they are
turned on again. This minimizes the total power consumption efficiently and guarantees maximum operational
reliability when the system is operated from a battery power source.
Fault messages are being displayed in plain text on the paging console displays and a floating contact is provided
for collective fault messages. An automatic protocol facility of the system's individual state of operation is
optionally possible. This protocol is stored in the DPM 4000's internal memory. If necessary, it can be displayed
on the screen of a connected computer or printed out via a printer.

5.1.3 Rear View
figure 5.3 DPM 4000 rear view
The following module ports and connections are located on the rear panel of the DPM 4000:
1. DC INPUT 24V ==
The DPM 4000's power supply source has to be connected here; a 24 VDC power supply or a PROMATRIX
system battery module using insulated AMP flat-connector plugs 6.3 x 0.8 mm. The DPM 4000 is protected
against polarization mismatch and all positive and negative conductors within the device are fuse-protected.
The fuses are located inside the enclosure on the printed board assembly 80430. The connection cables have
to be 1,5 mm2in diameter at least. With this diameter the cable length of a single path should not exceed 4.0
m (max. drop in voltage <1V).
CAUTION: Using the DPM 4000 is only permissible with batteries that are not grounded or provide a
grounded negative pole. Operation with grounded positive pole is not admissible.
2. SIGNAL INTERFACE
Signal Pins Description
+24V == 124 V== voltage output for the supply of external components. The maximum current
handling capacity is 400 mA.
GROUND 2Ground connector of the 24 V== voltage output.
READY 3, 4, 5 Floating output for the indication of the system's operation mode. In the normal ready
mode the READY relay is activated. When internal errors occur or external devices
show faulty behavior, the READY-relay drops. The relay is connected to the FAULT
LED indicator on the front panel of the DPM 4000 providing indication of the
operational status directly on the appliance.
INP1 6, 7 Floating input for monitoring / remote controlling the battery power supply, usually
connected to a battery module or battery charging unit. Since this input can be freely
programmed, using it for any other 24 V control signal is possible as well.
INP2 8, 9 Floating input for monitoring / remotely controlling the power supply, usually
connected to the 24 V== system power supply. Since this input can be freely
programmed, using it for any other 24 V control signal is possible as well.
DCF77 10, 11 Socket for connecting an external DCF 77 antenna. This input provides the supply
voltage and simultaneously serves as input for the decoded DCF 77 signal. Only
connecting the NRS 90193 DCF 77 receiver is admissible while polarity is not a
critical factor. However, according to CE regulations, shielded cabling has to be used.
Connect the shield to the connector's pin 10 and the signal line to pin 11.

3. RS-232 PC INTERFACE
This 9-pole PC-interface is meant for connecting a computer (female, pin 2 = TXD, pin 3 = RXD, pin 1 =
ground). It is used to transfer data between the PC and the DPM 4000 during system configuration as well as
for control, monitoring, and remote diagnosis purposes. The PC is connected to the DPM 4000 utilizing a
standard 1:1 D-sub extension cord with male connectors on one end and female connectors on the other.
As an alternative to the RS-232 port, an optical IrDA interface is provided on the front panel of the appliance
offering the possibility for wireless data transmission.

4.REMOTE CONTROL socket
This 8-pole RJ-45-type socket is meant for connecting DCS 401 control modules or DPA 4000 power
amplifiers with remote interface. The connector provides a RS-485 interface for communicating with control
modules and power amplifiers (pins 4 / 5), a balanced audio input for the insertion of external monitor signals
(pins 7 / 8), and a 24 V== supply voltage output for the supply of external modules (pin 1 = +24 V, 1 A max.,
pin 2 = GND). A programmable electronic fuse (adjustable to 330 mA, 660 mA, 990 mA) protects the voltage
output against short-circuit and overload. External devices are connected through common RJ-45 extension
cords. For additional information, please refer to the corresponding chapters of the individual device.
figure 5.5 pin-assignment of the REMOTE CONTROL socket
The RS-485 bus may not exceed a maximum length of 1,000m and must follow a line-structure (short stub
cables are permissible). Cabling has to be carried out using twisted pair cables (38.400 Bd, 8N1)

5. MONITOR OUTPUT socket
The audio signal of the integrated monitor amplifier is outputted via this connector. In standard configuration,
this output is set for the connection of headphones. It is also possible to directly connect a loudspeaker with
minimum load impedance of 8 Ohms. To achieve higher output capacity it is possible to set the internal
monitor amplifier to bridged operation. Thus some internal jumpers have to be re-set as shown in the figure
below.

5.1.5 2-Channel Paging Station Module (NRS 90215)
This 2-channel audio input module is meant for the
connection of DPC 4000 Series paging consoles. Each of
the two input channels provide RJ-45 sockets allowing
the connection of up to 4 paging stations plus paging
station extensions per input. The microphone terminals
are interconnected via 6-conductor parallel cables. The
module can be installed in slot 1 and slot 2.
Next to the electronically balanced audio input, each input
connector provides a serial RS-485 interface port and the
power supply connection for the paging stations (see
also: pin-assignment of the RJ-45 connector). The paging
stations' power supply employs an electronic,
programmable fuse, through which the maximum output
current can be matched to meet actual system
accommodations. This prevents the entire installation
from malfunction, in case of short-circuit occurring in a
single paging station only.
Input channels can be switched separately onto the
monitor bus and you can monitor the audio signal via
headphones or loudspeaker, either which is connected to
the monitor output. If necessary, retrofitting the audio
inputs with transformers is possible.

figure 5.7 2-channel paging station module
Note: When connecting several paging consoles to a single input, please keep in mind that line
interruption or short-circuit can cause malfunction of several or even all paging stations of that
specific line. In emergency alert installation, connecting security-related consoles to individual
inputs is therefore of major importance.
