Heat development
The table in chapter Specification can be used to determine the requirements for power
supply and supply lines. The power drawn from the mains is converted into output power to
feed the loudspeaker systems and heat. The difference between power consumption and
power output is called power dissipation (Ploss). The heat that is generated by losses might
stay in the rack shelf and has to be dissipated by appropriate measures. The table can be used
to calculate the thermal ratio inside of a rack shelf/cabinet or for dimensioning the perhaps
required ventilation measures. The Ploss column lists the power dissipation for various
operating conditions.

Connection
Audio inputs
The power amplifier has four audio input channels. With the help of integrated pilot tone
monitoring, a missing or faulty input signal can be detected reliably. Please refer to section
Circuit diagram, page 32 for details about the internal audio routing of the device.
RJ-45
The pin assignment of the LINE 1-4 IN / THRU audio input sockets allows connecting the
power amplifier to the RJ-45 audio output socket of a controller using standard RJ-45 patch
cables. The two RJ-45 sockets are switched in parallel which allows looping through the audio
signal.
Figure 6.1: Pin assignment of LINE IN 1-4 socket
Notice!
Do not use Ethernet crossover cables to connect audio inputs. Only use high quality straight
through Ethernet cables with shielding.
Notice!
Do not plug a CAN terminating resistor into the LINE IN 1-4 socket.

Euroblock
The L1 or L2 audio inputs allow to connect local audio sources, e.g. in stand-alone mode. The
audio signal L1 is mixed with input signal LINE IN 4 (provided via RJ-45) and amplified by
amplifier output channel 1. Audio signal L2 is mixed with input signal LINE IN 4 and amplified
by amplifier output channel 2.
Notice!
If local audio sources should be used while full system supervision is required, a pilot tone
must be available at LINE IN 4. Please refer to section Circuit diagram, page 32 and the
documentation of IRIS-Net.
The audio inputs are electronically balanced. You must always use a balanced audio signal at
the input of the device where this is possible. The scope of delivery for the device includes a
3-pin connector. Conductor cross-sections of 0.14 mm² (AWG26) to 1.5 mm² (AWG16) can be
used.
Recommended connecting cable: balanced cable with shielded flexible 2 x 0.14 mm².
Balanced cabling
The following illustration shows the balanced cabling of an audio input (or output) on the
device.
Figure 6.2: Balanced cabling
Unbalanced cabling
If the connecting cable(s) is/are very short and no interference signals are to be expected in
the environment of the device, then an unbalanced signal can also be connected. In this case,
it is imperative that a bridge in the connector between the shield and the inverting pin is
switched (see diagram below), otherwise the level can drop by 6 dB. However, for reasons of
immunity to external interference sources such as dimmers, mains supplies, HF control lines
etc., balanced cabling is always preferable.

Operation manual 18-Jun-2015 | 04 | F01U306898

Figure 6.3: Unbalanced cabling
Audio output
The audio outputs on the device are galvanically insulated and are constantly monitored for
ground fault. For each output channel there are 6 pins, two pins for 0V, two pins for 70V and
two pins for 100V speaker lines. The delivery for the device includes 6-pole connectors.
Conductor cross-sections of 0.14 mm² (AWG26) to 1.5 mm² (AWG16) can be used.
Recommended connecting cable: flexible CU strand, LiY, 0.75 mm².
For ease of installation, the connector can be removed. With regard to the maximum number
of speakers that can be connected, speakers can be connected until the point at which the
total power consumption of the speaker network corresponds to the nominal power value of
the output stage, where the rated load resistance of the output stage outputs is not to be
exceeded. The nominal power values and the rated load resistances of the outputs can be
found in the section entitled Technical data.
Notice!
Conductor cross-section
The maximum voltage drop must be less than 10% to avoid alarm signal attenuation and
ensure a sufficient signal level of the pilot tone for (optional) EOL modules.
Notice!
Do not use 70V and 100V outputs simultaneously.
Danger!
It is possible that during operation shock hazard voltages (> 140 V peak value) may be present
at the outputs. Therefore, the connected loudspeaker zones have to be installed in accordance
with applicable safety regulations. When installing and operating 100 V loudspeaker networks,
compliance with the VDE regulation DIN VDE 0800 is mandatory. Especially, when 100 V
loudspeaker networks in alarm system applications are concerned, all safety precautions have
to be in accordance with the safety class 3 standard.

18-Jun-2015 | 04 | F01U306898 Operation manual

Supply voltage
The device is normally operated via the AC mains input (120–240 V). In addition, a battery
input is available for emergency power operation (24 V DC).
Notice!
If the AC and DC power inputs are used, it is recommended to connect AC power first, then
switch on the device, then connect the DC power source.
Notice!
A power-on delay can be programmed for the PVA-2P500 via IRIS-Net. Upon switching on the
power supply the device does not start until the set delay time has elapsed. If several devices
are operated on the same automatic circuit breaker (or battery), cascaded switch-on can be
accomplish by programming individually different power-on delays for the devices. This also
prevents the magnetic trip of an automatic circuit breaker from acting and thus disconnecting
the devices from the mains supply, when various devices are switched on at the same time.
AC input and power switch
The power supply to the device is provided via the mains input using the supplied IEC cable
only. During installation, always disconnect the device from all supply voltages. Connect the
device only to a suitable power supply that meets the requirements specified on the type
plate. The associated fuse is located on the inside of the amplifier and is not accessible from
outside of the device.
The power switch at the rear separates the device from the power supply when the switch is
in the off position (0). The device starts booting up when the switch is in the on position (|). A
soft-start circuit limits in-rush current peaks occurring during this process. The speakers are
switched on via the output relays after a time delay. This effectively suppresses any audible in-
rush noises.
DC input
6.3
PAVIRO Amplifier Connection | en 19
Operation manual 18-Jun-2015 | 04 | F01U306898

The device automatically switches to DC input in the event of failure of the mains supply
voltage. For this input, connect a 24-volt DC source to the DC INPUT input. The scope of
delivery for the device includes a 2-pin connector. Conductor cross-sections of 2 mm² to
6 mm² can be used.
Recommended connecting cable: flexible CU strand, LiY, 4 mm².
The DC input is protected against incorrect polarity and overload. The associated fuse is
located on the inside of the device and is not accessible from outside of the device. The
threshold of the internal audio peak limiters are lowered by 3 dB if DC is connected only.
Notice!
The DC input cannot be switched off. The power switch can only be used to switch off the
mains power supply.
CAN BUS
This section contains information about the connection of the device to the CAN BUS and the
correct setting of the CAN address.
Connection
The device has two RJ-45 jacks for the CAN BUS. The jacks are connected in parallel, and act
as an input and for daisy chaining the network. The CAN bus allows different data rates to be
used, where the data rate is indirectly proportional to the bus length. If the network is small,
data rates of up to 500 kbit/s are possible. In larger networks, the data rate must be
decreased (down to the minimum data rate of 10 kbit/s), please refer to section Configuring
the CAN baud rate.
Notice!
The data rate is preset to 10 kbit/s in the factory.
The following table explains the relationship between data rates and bus lengths/network
size. Bus lengths of over 1,000 m must be implemented only with CAN repeaters.
