PA1plus broadcast over IP system

Transform Your IP Network into a Professional Public Address Solution

The Snom PA1+ is a professional-grade, SIP-based broadcast and public address system engineered to extend the power of your IP telephony infrastructure into a comprehensive overhead paging and notification platform. As an advanced evolution of Snom's proven PA1 technology, this versatile device functions as a SIP bridge that seamlessly integrates with your existing IP PBX and speaker infrastructure, enabling crystal-clear HD audio announcements, background music distribution, and even automated door or gate control—all over your standard network.

It is specifically designed for offices, retail spaces, medical facilities, warehouses, schools, and any environment requiring reliable, scalable broadcast communication.

Core Technology: High-Performance Amplification and Flexible Audio Output

At the heart of the PA1+ is a powerful integrated 6.5-watt Class D high-performance amplifier capable of driving 600-ohm speakers directly to fill large rooms with exceptional HD audio clarity. For larger-scale applications requiring multiple speakers or higher wattage, the PA1+ provides a line-level 600-ohm interface to connect external commercial amplifiers, allowing it to serve as an auto-answering SIP preamp for comprehensive facility-wide PA systems.

The device supports a full suite of professional audio codecs including G.711, G.722, G.723.1, G.726, and G.729, ensuring pristine voice quality and broad compatibility across VoIP platforms.

Versatile Applications: Beyond Simple Paging

The PA1+ is designed for remarkable versatility far beyond basic announcements. It can be controlled from any Snom SIP phone or central source via simple call, key combination, or DTMF tones, enabling instant paging to specific zones or entire facilities.

The device features four freely configurable relay contacts that can be remotely activated via SIP or DTMF, allowing seamless integration with door opening systems, garage gates, loading dock barriers, strobe lights for visual alerting, and other external devices. It also supports multi-cast relay for up to four SIP identities, enabling sophisticated zone-based paging configurations .

Installation, Connectivity, and Enterprise-Grade Management

Engineered for effortless deployment, the PA1+ offers flexible power options including Power over Ethernet (PoE) IEEE 802.3af Class 3, eliminating the need for separate power cabling in PoE-enabled networks. Dual Gigabit Ethernet ports with an integrated switch allow daisy-chaining of additional network devices such as LAN cameras, simplifying security system expansion.

Configuration is accomplished through an intuitive menu-driven web interface, with support for automatic provisioning via HTTP/HTTPS/TFTP and Snom's Secure Redirection and Provisioning Service (SRAPS) for centralized, hands-free management across multiple units.

Rugged Design and Comprehensive Security

Built for professional environments, the PA1+ features a robust housing designed for wall mounting, with clear LED status indicators for call and power status visible from a distance . A dedicated IP/Reset button allows for easy network identification during installation.

Security is paramount, with support for TLS, SRTP, SIPS, and SHA-2 encryption standards, ensuring all communications and control signals remain protected against unauthorized access. The device operates on a reliable Linux-based system and supports both IPv4 and IPv6 network environments.

Target Applications: The Complete IP Broadcast Solution for Any Organization

The Snom PA1+ Broadcast over IP System is the definitive solution for any organization seeking to leverage their existing IP network for professional-grade public address and paging. It is ideally suited for office buildings requiring zoned announcements, retail stores broadcasting promotions, medical facilities needing overhead paging, schools and universities for daily announcements and emergency notifications, warehouses for operational communication, and manufacturing plants integrating alerts with security systems.

Its combination of 6.5-watt integrated amplification, flexible external PA support, configurable relay controls, PoE convenience, enterprise security, and seamless SIP integration makes it an exceptionally versatile and cost-effective broadcast platform for modern business communication.
