Audio Network Interface
Overview
General Description
The Shure ANI4IN Audio Network Interface converts 4 analog audio channels into independent digital audio channels on a
Dante network. Microphone, auxiliary, and line-level devices are supported, with adjustable gain and +48V phantom power for
each channel. In networked conferencing systems, the Audio Network Interface provides a simple way to connect analog
equipment onto the audio network, such as wireless microphones. The web application controls signal routing and channel set
tings from any computer connected to the same network.
