250 Watt / 70V Telecom Paging Amplifier
Model PA-250
For more info, see DOD 501.
The PA-250 is a 250 Watt 70V Telecom Paging Amplifier that is capable of
driving up to two hundred fifty (250) 70V speakers and/or paging horns
(each speaker set to "1 Watt tap"). The small 1U rack size chassis is
possible because the PA-250 uses new amplifier technology that is 3 times
more efficient than old designs competitors use. High efficiency means
much less heat dissipation, smaller size, higher reliability, and lower cost.
The PA-250 provides more paging power at less cost than competitors.
There are many advantages of using a 70V distributed audio paging
system, such as being able to put more speakers on a wire run, having
longer speaker wire runs, using smaller gauge wire, and being able to set
the volume of each speaker independently.
The PA-250 connects to any type of analog telecom interface, such as
Paging Port, Trunk Input, Analog Station, FXO (Loop Start), and FXS (Ring
Trip).
15 Watt Paging Amplifier with Background Music and Loud Ringing
The PA-15 interfaces with virtually any telephone system to provide 15 Watts of paging power - enough to drive
fifteen 8-Ohm paging horns or speakers. This small and light weight chassis design is possible by utilizing new
amplifier technology that is 300% less inefficient than old designs competitors use. High efficiency means much
less heat disipation, smaller size, higher reliability, and lower cost.
The PA-15 provides 36V talk battery for interfacing with an FXO or unused analog line input/trunk port. With
the flip of a switch, the unit can connect to a FXS or PABX/Centrex station ring trip port or connect to a 600
Ohm paging port. When interfacing with systems that do not provide a paging contact closure, the built-in voice
activation (VOX) is in control.
For more information on the PA-15, see DOD 486.
30 Watt Paging Amplifier with Background Music and Loud Ringing
The PA-30 can directly drive up to thirty (30) 8 Ohm paging speakers or fifty (50) 70V or 25V paging speakers.
This small and light weight chassis design is possible by utilizing new amplifier technology that is 300% less
inefficient than old designs competitors use. High efficiency means much less heat disipation, smaller size, higher
reliability, and lower cost.
The PA-30 provides loud ringing and paging to electronic key systems, 1A2 Key systems, PABX's as well as No-
KSU phones and multi-line phones. The PA-30 eliminates the installation of multiple bells, relays and paging
cards. The unit comes complete with a power supply, and integrated 30 Watt amplifier.
For more information on the PA-30, see DOD 489.
60 Watt Compact Two Zone Amplifier to Drive 60 Paging Speakers
The PA-60 can directly drive up to sixty (60) 8 Ohm paging speakers or one hundred (100) 70V or 25V paging
speakers. Both channels can be fed the same input so the PA-60 can be used as a single large amplifier, or
each channel can be fed different inputs so the PA-60 can be used as a two zone amplifier.
Since each input has its own gain adjustment, one zone can be turned up louder for warehouse paging horn
speakers, and the other zone can be turned down for office ceiling speakers. Two zones can also be helpful
for installations in which one group of speakers is connected to a source that provides background music using
the Viking PI-1A Paging Interface unit, and the other zone provides only paging.
For more information on the PA-60, see DOD 493.

250 Watt / 70V SIP / Multicast Paging Amplifier
The Viking model PA-250-IP SIP/Multicast Paging Amplifier provides up to
250 Watts of loud paging for SIP based VoIP phone systems (hardware or
hosted/cloud based service provider). The PA-250-IP can be used for
standard SIP endpoint paging or multicast paging.
The PA-250-IP can drive up to two hundred fifty (250) 70V speakers and/or
paging horns (each speaker set to "1 Watt tap"). The small 1U rack size
chassis is possible because the PA-250-IP uses new amplifier technology
that is 3 times more efficient than old designs competitors use. The high
efficiency of the PA-250-IP means much less heat dissipation, smaller size,
higher reliability, and lower cost.
The unit easily connects with a single CAT5/6 cable from your network
switch. The night ring feature is programmable for time of day and day of
week to enable loud ringing for after hour incoming calls.
