do not listen at high volume levels for long periods.
21. Replacement parts – When replacement parts are required, be sure the service
technician has used replacement parts specified by the manufacturer or having the same
characteristics as the original part. Unauthorized substitutions may result in fire, electric
shock or other hazards.
22. Safety check – Upon completion of any service or repairs to this apparatus, ask the
service technician to perform safety checks to determine that the apparatus is in proper
operating condition.
Danger!
Overloading – Do not overload outlets and extension cords as this can result in a risk of fire or
electric shock.
23. Power sources – This apparatus should be operated only from the type of power source
indicated on the marking label. If you are not sure of the type of power supply you plan to
use, consult your appliance dealer or local power company. For apparatuses intended to
operate from battery power, or other sources, refer to the operating instructions.
24. Power lines – An outdoor system should not be located in the vicinity of overhead power
lines or other electric light or power circuits, or where it can fall into such power lines or
circuits. When installing an outdoor system, extreme care should be taken to keep from
touching such power lines or circuits, as contact with them might be fatal. U.S.A. models
only – refer to the National Electrical Code Article 820 regarding installation of CATV
systems.

Danger!
Object and Liquid entry – Never push objects of any kind into this apparatus through
openings as they may touch dangerous voltage points or short-out parts that could result in a
fire or electric shock. Never spill liquid of any kind on the apparatus.
25. Coax grounding – If an outside cable system is connected to the apparatus, be sure the
cable system is grounded. U.S.A. models only: Section 810 of the National Electrical
Code, ANSI/NFPA No.70-1981, provides information with respect to proper grounding of
the mount and supporting structure, grounding of the coax to a discharge apparatus, size
of grounding conductors, location of discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
26. Protective grounding – An apparatus with class I construction shall be connected to a
power outlet socket with a protective grounding connection.
Protective earthing – An apparatus with class I construction shall be connected to a
mains socket outlet with a protective earthing connection.
Note for power connections
– For permanently connected equipment, a readily operable mains plug or all-pole mains
switch shall be external to the equipment and in accordance with all applicable
installation rules.
– For pluggable equipment, the socket-outlet shall be installed near the equipment and
shall be easily accessible.
This label may appear on the bottom of the apparatus due to space limitations.
Caution!
To reduce the risk of electrical shock, DO NOT open covers. Refer servicing to qualified
service personnel only.

Short information
The PVA-2P500 class-D amplifier is a 2 ✕ 500 W professional audio amplifier for evacuation
purposes. It can be operated from both the mains and a DC supply. The output voltage is
galvanically insulated and is constantly monitored for ground fault. An energy-saving mode and
temperature-controlled fans reduce energy consumption and noise levels. The control and
monitoring functions are performed via CAN bus. This amplifier is designed for operation in an
emergency evacuation system. It can be used as system amplifier or in stand-alone mode. The
amplifiers are usually controlled via a controller and configured using IRIS-Net.
The power amplifier has the following features:
– Floating 100 V or 70 V power outputs
– High efficient amplifier blocks in class-D technology
– Outputs idling and short circuit-protected
– Mains operation 120–240 V (50/60 Hz) and/or 24 V DC emergency backup
– Electronically balanced inputs
– Temperature monitoring function
– Pilot tone and ground fault monitoring function via PVA-4CR12 controller or PVA-4R24
router
– Processor control of all functions
– Monitoring of the processor system via watchdog circuit
– Non-volatile FLASH memory for configuration data
– Internal monitoring function
– Integrated audio relays
– Line monitoring function
The power amplifier is processor-controlled and equipped with extensive monitoring
functions. Line monitoring for the CAN bus and for audio transmission allows line
interruptions and short-circuits to be detected and indicated to the user.
