TOA Electronics IP-A1PA12 12W IP Power Amplifier

The TOA Electronics IP-A1PA12 is a compact IP power amplifier built to amplify audio received over a network for paging and public address systems. With a 12 W amplifier and high impedance speaker line outputs, it supports clear distribution to 100V, 70V, and 25V line speakers. It is designed for IP audio deployments that need reliable zone amplification in commercial facilities.

This amplifier supports SIP, ONVIF, and multicast streaming, plus local broadcasting from a LINE or MIC input with selectable phantom power. It also provides internal message playback with storage for up to 20 audio files and triggering via control inputs or remote API (HTTP/HTTPS) commands. PoE+ powering simplifies installation while keeping network audio and amplification in one compact endpoint.

The IP-A1PA12 helps standardize IP paging across buildings while maintaining flexible routing and priority control between broadcast modes. It includes an external amplifier input capability so connected speakers can be switched between the built-in amplifier and an external PA amplifier when required. It is well suited for schools, offices, healthcare, hospitality, and other sites that need network-based announcements and zone audio control.
