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.

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-IP features individual level controls with LED indicators for each input, automatic peak limiting, multiple amplifier protection modes, an adjustable Automatic Level Control, and Bass & Treble Controls.

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.

A 600 Ohm output to allow more paging amplification to be added if needed. The PA-250-IP has inputs for Background Music and Aux Input. The Aux Input allows the addition of another audio source such as a clock-controlled tone generator (Viking model CTG-1A or CTG-2A), or emergency notification system (Viking model DNA-510).
