4.4. Input/output contacts
The amplifier has nine configurable input / output
contacts.
To use these, the functionality of each contact
must be defined through the P.A. Manager
software (see section 6.2.3).
Contacts configured as input:
To activate a contact configured as input, this
contact must be connected to ground.
By way of example, these inputs are used to
detect and notify the system of alarms, or to
activate local pre-recorded messages…
Contacts configured as output
They are open collector outputs. These outputs
can be used to activate the selection of zones of
an MC-12/24L, activate the priority of an external
device, light a LED…
4.5. Battery power supply input
This supply allows the equipment to be used in
safety installations, connecting a 24 V DC
battery.
The ON/OFF switch does not cut off the supply
from the battery.
It is possible to monitor the presence of the 24 V
DC battery input.
The battery power fuse is situated inside the unit,
in the contact input/output circuit. To gain access
to the fuse, in the event of repair, it is necessary
to remove the cover of the unit. A spare battery
fuse is supplied with each amplifier. The value of
this fuse varies according to the amplifier model.

4.6. Ground to chassis
connection
In all Public Address installations it is very
important that there is one single point of
connection between the signal ground connection
and the mains supply ground contact.
If the Public Address installation is composed of
several equipment units, their chassis will
probably be joined, either by means of the
ground terminal of the mains connection, or
because they are mounted in a rack cabinet.
If the ground connections are also joined by the
signal circuits, it is advisable to remove the
jumper between the ground connection and the
chassis from all the units except one.

4.7. FAIL relay
Solid state relay. It switches when:
a) The power supply of the amplifier fails.
b) The maximum temperature set by the P.A.
Manager software is exceeded.
c) The connection in both Ethernet inputs (ETH A
and B) is lost.
d) A high impedance / open line fault is detected
in the loudspeaker line.
e) An internal communication or firmware error
is detected in the amplifier.
4.8. Loudspeaker line outputs
The loudspeaker line output is effected by means
of a transformer that has low impedance (4-8-16
ohms) and high impedance (50-70-100 V)
outputs.
The connection must be made between terminal
"0" and the terminal corresponding to the
selected impedance or voltage.
When working with the 50, 70 and 100 V lines, it
should be remembered that:
The loudspeakers must be equipped with a
line transformer.
The total connected power will be the sum of
the power absorbed by the loudspeakers and
this must be between 50% below and 20%
above the rated power of the amplifier.
The power absorbed by a loudspeaker with a
transformer is indicated on a 100 V line. If
the amplifier is connected to the 70 V line, it
will absorb half the indicated power, and if it
is connected to the 50 V line, it will absorb a
quarter of this power.

PRIORITY analog input is played.
b) When an announcement that comes from the
EMERGENCY analog input is played.
c) When an announcement configured as
PRIORITY and originating from one of the ETH
inputs is played.
d) When a pre-recorded message from the
Coldfire Flash memory of the amplifier is played.
e) When a pre-recorded message from the Flash
memory of the MP3 circuit of the amplifier is
played.
4.10. USB input for pre-
recorded messages in MP3 format
This connector allows to access to the amplifier
MP3 Flash memory.
This memory can store files in MP3 format to be
used as pre-recorded messages (see section
5.1).
4.11. Emergency (EMG) volume
Regulates the level of the signal applied to the
emergency input.
4.12. PRE OUT volume
Regulates the level of the PRE OUT output.
4.13. Emergency input (EMERGENCY IN)
Unbalanced local analog input through an RJ45 connector. Its sensitivity is 0 dBu (775mV).
It has absolute priority over any other signal from the amplifier (ETH inputs, PRIORITY and PROGRAM
inputs, and pre-recorded messages activated through the input/output contacts strip).
There are three types of emergency announcement:
Live voice emergency message: The audio channel of the emergency input is opened when pin
number 6 (speech preference) is connected to pin number 8 (GND) of the connector. Its activation has
priority over any other signal from the amplifier, including the other types of emergency
announcement.
Pre-recorded Evacuation message: This is pre-recorded message number 1 in the MP3 Flash
memory of the amplifier. It is activated when pin number 4 is connected to pin number 8 (GND) of the
connector. Its activation has priority over the activation of the pre-warning message and all other
signals from the amplifier.
Pre-recorded Pre-warning message: This is pre-recorded message number 2 in the MP3 Flash
memory of the amplifier. It is activated when pin number 5 is connected to pin number 8 (GND) of the
connector. Its activation has priority over all signals from the amplifier that are not emergency
signals.
Activation of any of the three types of emergency announcement activates the paging security auxiliary
relay (see section 4.9).
The emergency input has a single volume adjustment situated on the back of the unit (see Figure 2, no.
11) and this affects the volume of live voice messages.

Cat 5 STP cable must be used for the connections.
The Emergency input has Emergency Surveillance (critical path) and Activation Contacts
Surveillance:
Emergency Surveillance (critical path): The device connected to the emergency input must
generate a high frequency signal (17720 Hz, 18000 Hz, 19250 Hz or 20000 Hz). The system performs
a constant check of the high frequency signal, generating an alarm in the event of short circuit,
interruption of continuity or disconnection of this input. The alarm generated is sent through the IP
network towards the control PC or the equipment units prepared to receive these alarms
(DVA-102ETH, FC-600ETH, DC-600ETH). The emergency surveillance function must be configured by
means of the P.A. Manager software (see section 6.7).
Activation Contacts
Surveillance: If the connections
shown in Figure 5 are made, the
system monitors the priority
contact and the two contacts for
activation of pre-recorded
messages from the emergency
input. In the event of short circuit
or disconnection, an alarm is
generated.

4.14. Priority input (PRIORITY IN)
Unbalanced analog input with an RJ45 connector and a sensitivity of 0 dBu (775 mV).
It has a priority contact which is activated by connecting pin no. 6 to pin no. 8 of the connector. When
this contact is activated, any signal of a lower priority level is cut off and priority is given to the PRIORITY
IN input, while the paging security auxiliary relay is activated at the same time.
This input is particularly suitable for receiving local announcements (e.g. a microphone with a speech
preference button…).
Cat 5 STP cable must be used for its connection.

4.26. ETHERNET A connector
RJ45 type connector. Used for connection to the
IP network. Cat 5 STP cable must be used for its
connection.
4.27. ETHERNET B connector
RJ45 type connector. Used, in a redundant
network, as a secondary connection to the IP
network. Cat 5 STP cable must be used for its
connection.
If the connection to ETH A fails, the amplifier
automatically switches to this B connection, so
that the PA system continues to operate.
4.28. IP ADDRESS DIP switches
The IP address of the amplifier is configured
through these 4 DIP switches. This address
identifies the amplifier in the network, and so
each unit must have a unique IP address.
An IP address is represented by means of a 32-
bit binary number. The IP addresses are
expressed as decimal notation numbers: the 32
bits of the address are divided into four octets
(an octet is a group of 8 bits). In the amplifier,
each octet is represented by A0 to A7 for the first
octet, B0 to B7 for the second octet, C0 to C7 for
the third octet, and D0 to D7 for the fourth octet.
In an octet, each bit can have the value 0 (DIP
switch OFF) or 1 (DIP switch ON). In order to
obtain the decimal value of the octet, the decimal
values of each bit that is in the ON position must
be added up (from left to right: 1, 2, 4, 8, 16,
32, 64 and 128).
Figure 14 shows an example in which the IP
address 192.168.100.128 is configured.
Table I shows all the DIP switch combinations
from 0 to 255.

5. LOCAL PRE-RECORDED MESSAGES
The amplifier has two internal memories in which files can be stored for subsequent use as local pre-
recorded messages: MP3 Circuit Memory and Coldfire Flash Memory.

The messages contained in the MP3 memory are immediately available when the amplifier is switched on,
thereby complying with the standard EN60849.
5.1.2. Transfer of messages to the MP3 memory of the amplifier
The files must be copied to the MP3 memory with a specific name format. Otherwise the messages
cannot be played.
The MP3 files must have the CRC protection activated (the majority of recording programs support this
option). This ensures constant surveillance of the integrity of messages 1 and 2 in the MP3 memory (files
0001… and 0002…). If there were to be any problem in these files, the amplifier sends an alarm message
through the IP connection towards the different units in the installation that have the capacity to receive
it (FC-600ETH, DC-600ETH, DVA-102ETH, UMX-02/0, control computer…).
To transfer the MP3 files to the amplifier, connect the computer that contains the messages to the
amplifier by means of the USB connector on the rear panel of the amplifier. Use the PC browser to copy
the files to the MP3 memory of the amplifier, which will be shown as an additional disk unit. The files
must be copied into the root directory of the unit, and folders should not be used.
