PAVIRO Amplifier

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).
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.
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.
