TOA Electronics IP-A1MP Microphone Panel with Call Switch for IP-A1 Series

The TOA IP-A1MP is a compact microphone panel designed for use with IP-A1 series devices in paging, intercom, and IP audio applications. It combines an omni-directional microphone, call activation, and status indication to support clear two-way communication. Use it to add a reliable wall-mounted talkback and monitoring point in commercial and institutional AV systems.

This microphone panel features an electronically-balanced microphone output with adjustable volume for clean signal delivery to compatible IP-A1 series equipment. A momentary push switch initiates calls while a green indicator confirms control input activity when phantom power is supplied. With control input and control output connections, it integrates easily into external control workflows.

Built for professional installs, the IP-A1MP supports surface or flush mounting using a standard electrical box for clean, consistent deployment. Its durable steel construction and included installation plate help deliver dependable performance in everyday facility communication. It is ideal for security desks, help points, conference support locations, and audio monitoring positions when paired with IP-A1 series devices.
