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

    Setting up the Audio Network Shure networked conferencing systems are comprised of Microflex Advance microphones and network interfaces, which operate entirely on a Dante™ network. Additional hardware, including network switches, computers, loudspeakers, and audio processors are described in the hardware component index.
  • Page 6 This diagram shows the entire signal path through a networked conference system. Signals from the near end and far end are exchanged through an audio processor connected to a phone system, or through a computer connected to the internet. Analog microphones connect to the network through the Shure ANI4IN, while loudspeakers connect through the Shure ANI4OUT.
  • Page 7 Expanded Control for Analog Devices Analog devices that are connected to the network through a Shure network interface (ANI4IN/ANI4OUT) benefit from additional remote control: Volume levels, equalization, and signal routing are managed through the web application. For example, adjusting loudspeaker volume or muting a wired microphone, which would normally be done from the hardware, can now be controlled remotely over the network.

    ANI4IN Audio Network Interface Shure Incorporated Levels and Metering Adjusting Input Levels Input Levels Before you begin, verify that levels from the analog devices with adjustable output levels are operating at nominal levels. The analog gain adjusts the level of the audio signal before it is converted from analog to digital. It is adjustable in 3 dB increments, with up to 51 dB total gain.

Analog gain adjustments affect the meter when set to pre-fader, but the digital gain adjustments do not.

    This device can connect with up to two Dante devices. The Shure MXA310, ANI22, ANIUSB-MATRIX and ANI4IN support multicast transmission. This means that flows can transmit to multiple devices -- as many as the network can support. If using unicast flows, each of these devices can connect with up to two Dante receiver devices.
