Toa Electronics IP-A1RM IP Remote Microphone

The IP-A1RM is an IP remote microphone which is designed to make audio broadcasts to IP-A1 series receiving devices via network. It achieves clear microphone announcements without distortion thanks to its built-in compressor effect. It allows both individual and group broadcast so that single or multiple IP-A1 series receiving device(s) can receive the audio as flexible PA operation. Key button operation controls a variety of functions such as internal audio file playback, HTTP command set transmission and physical control outputs to control external devices.
