Product Details

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 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.

The PA-250-IP has the power to drive up to two hundred fifty (250) 70V speakers and/or paging horns. 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. High efficiency means much less heat dissipation, smaller size, higher reliability, and lower cost. The PA-250-IP provides more paging power at less cost than competitors’ offerings.

70V distributed audio paging systems have many other cost savings advantages such as being able to put more speakers on a wire run, having longer speaker wire runs, use of smaller gauge wire, and being able to set the volume of each speaker independently.

Other inputs include Background Music and Aux Input. A 600 Ohm output allows additional paging amplification to be added for an even larger system. 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 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), to name a few.


Applications

  • Amplified SIP endpoint or multicast IP paging for: schools, hospitals, retail stores, office spaces, etc.
  • Provide multicast background music and sound masking
  • Paging systems requiring 8 to 250 speakers
  • Installations that can utilize the below advantages of a 70V distributed audio system:
    – Allows for longer wire runs using smaller gauge speaker wire to save costs
    – Many more speakers can be connected on the same wire run to save costs
    – Each speaker’s volume can be individually set using its own power taps
