Product Description
Toa IP-A1PA12 Compact 12 Watt Amplifier
Overview
The IP-A1PA12 is a compact 12 W amplifier which is designed to amplify audio signals received through network. It is equipped with 25 V, 70 V and 100 V speaker line outputs to drive wide range of high impedance speakers. With an external amplifier input capability, speaker(s) can be driven by internal amplifier or external amplifier by switching over. It allows integrations with IP camera systems by using ONVIF protocol, paging from IP phone systems by using SIP protocol and group broadcast by multicast streaming. Max. 20 audio files can be registered and they can be played back by control inputs or remote API (HTTP) commands.
Features
