Description
Need 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

FAQ
How loud is the built-in amplifier?
The integrated 6.5-watt Class D amplifier is designed to fill medium-sized rooms with clear HD audio when paired with standard 8–32 ohm speakers.
Can I use it with my existing multi-speaker PA system?
Yes—the 600-ohm line output works perfectly as a preamp for larger setups that use an external high-power amplifier.
Does it support background music?
Absolutely. You can stream background music alongside announcements thanks to the HD audio codecs and flexible SIP/multicast capabilities.
How do I control external devices like doors?
The four programmable I/O pins can be triggered remotely via SIP calls or DTMF tones to open electric door latches, activate lights, or run other simple controls.
Is Power over Ethernet supported?
Yes—PoE IEEE 802.3af Class 3 keeps installation clean. If your switch doesn’t provide PoE, a 5V DC adapter is available separately.
Can I mount it on the wall?
Yes, the included brackets and drilling template make secure wall mounting quick and straightforward in any indoor location.
