TOA Electronics IP-A1RM IP Remote Microphone for IP-A1 Series Paging

The TOA IP-A1RM is an IP remote microphone designed to make live audio broadcasts to IP-A1 series receiving devices over a network. It supports flexible IP paging for commercial facilities that need clear announcements to one zone or multiple zones. Use it as the operator microphone endpoint for network-based public address and paging workflows.

The built-in compressor effect helps deliver clear microphone announcements without distortion, and the angle adjustable gooseneck microphone supports comfortable desk operation. It supports both individual and group broadcast using SIP broadcasting for unicast audio streaming and multicast audio streaming for group paging. Ten selection keys can be assigned to initiate broadcasts or trigger controls such as internal audio file playback and HTTP/HTTPS command set transmission.

For daily reliability, the IP-A1RM includes a GUI calendar scheduler with up to 2,000 settings plus event actions triggered by control inputs. It also provides a system mute function to mute broadcasts made by IP-A1 series devices on the same network when required. PoE powering and integrated monitoring features make it a practical IP paging microphone for schools, offices, healthcare, and other multi-zone environments.
