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)
Danteenabled 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.
Danteen
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 microphonelevel 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.
