Snom PA1+ SIP Public Announcement System – 6.5W HD Audio Paging Amplifier with Relay Control for Offices & PA UpgradesNeed crystal-clear announcements that cut through noise in offices, warehouses, or public spaces—without ripping out your existing speakers or wiring? The Snom PA1+ makes it simple. It connects your SIP phone system straight to your public address setup, delivering HD-quality audio for paging, background music, or emergency alerts from any compatible phone. Facilities managers and IT teams love how it upgrades old analog systems to modern SIP in minutes while adding smart controls like door access or lighting triggers. The Telecom Spot Take The Snom PA1+ stands out as a smart, future-proof upgrade. Its 6.5-watt Class D amplifier handles single-speaker setups perfectly for smaller rooms, while the 600-ohm line output lets you tap into bigger multi-speaker systems with an external amp. Four programmable I/O pins give you real-world control—open doors, flip lights, or trigger alarms right from a SIP call or DTMF tone. Gigabit PoE keeps cabling clean, the wall-mount design fits anywhere, and HD audio ensures every message lands loud and clear. It’s the practical choice when you want reliable paging that scales with your business and integrates seamlessly with most SIP platforms. Applications where we use the Snom PA1+: Large PA systems driven by external amplifier(s) Small PA systems driven by internal PA1+ amplifier (eg. door answering system), and internal relay to open door(s) Phone ringer amplifier with ability to drive strobe light as visual indicator Multi-cast relay up to 4 SIP identities to four multi-cast IP addresses Key Features Built-in 6.5W Class D amplifier powers 8–32 ohm speakers directly so you get instant, high-volume announcements in meeting rooms, hallways, or retail floors without extra hardware. 600-ohm line output connects to existing or expanded PA systems and external amplifiers for larger facilities that need more reach. 4 programmable I/O pins let you remotely control doors, lights, strobe lights, or other devices via SIP calls or DTMF tones—perfect for automated access or visual alerts. Dual Gigabit Ethernet ports with PoE (IEEE 802.3af, Class 3) simplify installation and let you daisy-chain cameras or other network gear without extra switches. HD audio support delivers crisp, professional sound for announcements and background music so every word is easy to understand. SIP and multicast paging with auto-answer means anyone on your phone system can page instantly—no special training required. Wall-mount ready with included brackets and a compact design that fits neatly in any environment while keeping everything secure and out of the way.
