System Overview

①Dante audio, power, and control

Each array microphone connects to the network over a single network cable, which carries Dante audio, Power

over Ethernet (PoE), and control information to adjust coverage, audio levels, and processing.

②Analog audio (microphone to network)

Analog equipment, such as a wireless microphone system or a gooseneck microphone on a podium, connects to

the Dante audio network through a Shure Network Interface (model ANI4IN) for a completely networked confer

encing system.

③Far-end audio (network to loudspeakers)

Danteenabled loudspeakers and amplifiers connect directly to a network switch. Analog loudspeakers and ampli

fiers connect through a Shure Network Interface (model ANI4OUT), which converts Dante audio channels into

analog signals, delivered through 4 discrete XLR or block connector outputs.

④Device control and Dante audio

Control: A computer connected to the network controls the microphone with Shure Designer software. You can re

motely adjust coverage, muting, LED behavior, lobe settings, gain, and network settings.

Audio: Route audio with Dante™ Controller or Shure Designer software. Dante Virtual Soundcard enables audio

monitoring and recording directly on the computer.

System Planning and Gear Requirements

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, loud

speakers, and audio processors are described in the hardware component index.

Shure components shown in this diagram:

Microflex Advance Microphones

The MXA910 and MXA310 are equipped with Dante outputs, and connect directly to a network switch.

Audio Network Interfaces

The interfaces are used to connect analog devices such as loudspeakers and analog microphones to the network.

ANI4IN: Converts 4 analog signals (separate XLR and block connector models available) into Dante digital audio

signals.

ANI4OUT: Converts 4 channels of Dante audio from the network into analog signals.

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 connect

ed to the internet. Analog microphones connect to the network through the Shure ANI4IN, while loudspeakers con

nect through the Shure ANI4OUT.

This diagram shows Microflex Advance components in context, with two rooms communicating through video

codecs.

Controlling Hardware and Audio Over the Network

Audio and hardware settings are managed through a computer connected to the same network.

Shure Hardware and Audio

Each Microflex Advance component has a web application which provides mixing and configuration tools to opti

mize sound quality.

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 appli

cation. 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.

Dante Signal Routing

You can manage signal routing with Dante Controller or Shure Designer software.

Hardware Component Index

Network Switch

The network switch provides central connectivity for

all networked components. Audio from any networked

Shure microphones that are connected to the switch

can be routed to any Dante-enabled device. The

switch sends and receives audio and control data,

while simultaneously powering the microphones and

audio network interfaces through PoE (Power over

Ethernet). See the network switch requirements () for

additional details.

Power over Ethernet (PoE) Requirements:

All Shure components included in these scenarios re

quire Power over Ethernet (class 0). If not provided

through the network switch, a PoE injector is required

to power the devices.

Shure Microflex Wireless Audio Network Interface (MXWANI)

The Microflex Wireless Audio Network Interface

(MXWANI) is a digital-to-analog breakout box with a

built-in gigabit network switch. It converts digital audio

from the network into analog signals for signal pro

cessing or amplification, and provides PoE over one

network port to power a device. For details, refer to

the Microflex Wireless user guide, available at http://

www.shure.com.

Audio Processor

Shure Incorporated

7/87

The audio processor sends and receives audio

through a VOIP server or a standard phone line. They

also provide digital signal processing, such as

acoustic echo cancellation.

Danteen

abled

Processors that support Dante con

nect directly to the network switch to

receive audio from Microflex Advance

microphones.

Analog When using an analog processor, a

converter (such as the Shure

ANI4OUT or MXWANI) is required to

deliver the analog audio from Mi

croflex Advance microphones to the

processor.

Video Codec

Like the audio processor, the codec sends and re

ceives audio signals alongside video signals between

the near end and the far end. Audio from the near end

must connect to the audio input on the video codec,

which is typically a stereo analog connection. The

Shure ANI4OUT Audio Network Interface converts the

audio to an analog signal for connecting to a codec.

Shure ANI4IN Audio Network Interface (Analog-to-Dante Converter)

The Shure ANI4IN Audio Network Interface converts 4

channels of analog audio into independent digital au

dio channels on a Dante network. Adjustable gain and

+48V phantom power deliver the flexibility to support

line, auxiliary, and microphonelevel devices. For net

worked conferencing systems, the Audio Network In

terface provides a simple way to connect previously

installed analog equipment onto the audio network,

such as wireless microphones for presenters. The

web application gives technicians and administrators

control over channel levels and settings from any

computer connected to the same network.

Shure ANI4OUT Audio Network Interface (Dante-to-Analog Converter)

Shure Incorporated

8/87

The Shure ANI4OUT Audio Network Interface con

verts 4 channels of Dante digital audio into discrete

analog signals. Available in both XLR and block con

nector versions, each box uses a single network cable

to receive audio and power using Power over Ethernet

(PoE). The web application gives technicians and ad

ministrators control over channel levels and settings

from any computer connected to the same network.

Amplifiers and Loudspeakers

Audio from the far end is routed to local loudspeakers.

Dante-enabled speakers or amplifiers connect directly

to the network switch, while analog systems require

an audio network interface to receive networked au

dio.

Computers and Control Systems

Browser-

Based

Web Ap

plication

A computer connected to the network

provides control of Shure networked

components through the web applica

tion for each device.

Dante

Software

A computer running Dante Virtual

Soundcard, Dante Controller, and

web conferencing software is used to

send and receive audio between the

near end and far end.

Control

Systems

(AMX,

Crestron,

etc.)

If using a third-party control system,

Microflex Advance microphones send

and receive commands over Ether

net. If an analog logic signal must be

sent over the network, the Shure

ANI4IN Audio Network Interface re

ceives analog logic signals and con

verts them into Ethernet control

strings.

System Use Cases

These use cases will help you understand how Shure devices fit in conference rooms, huddle rooms, and multi

purpose spaces.
