Signal Flow and Connections
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.
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
Shure IncorporatedANI4IN
2017/10/306/32
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 connected to the internet. Analog microphones connect to the network through the Shure ANI4IN,
while loudspeakers connect through the Shure ANI4OUT.
Shure IncorporatedANI4IN

Controlling Hardware and Audio Over the Network
Audio and hardware settings are managed through a computer connected to the same network.
Shure IncorporatedANI4IN
2017/10/308/32
Shure Hardware and Audio
Each Microflex Advance component has a web application which provides mixing and configuration tools to optimize 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 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.
Dante™ Signal Routing
Signal routing between devices is managed through Dante Controller software, provided by Audinate™ .

Connections and Signal Flow
① MX396 (Dual-element)
In addition to running the audio signals, this boundary microphone features three additional wire leads for logic connections. This allows the switch on the microphone
to send a logic mute signal to other equipment on the network, and to receive a logic LED control signal.
② MX392
In addition to running the audio signal, this boundary microphone features three additional wire leads for logic connections. This allows the switch on the microphone

③ ULX-D Receiver
Wireless microphones connect to the network interface through the balanced analog outputs on the receiver.
④ Network Switch
Provides connectivity between the Dante™ audio network and the computer that controls signal processing and routing.
⑤ Computer
A computer or tablet running the web application provides independent gain control for each connected device.
Input: Analog (4 XLR or Block Connectors)
Each Audio Network Interface has 4 analog inputs with variable analog gain for line, auxiliary, and microphone-level signals. Examples of devices to connect to
the network with the Audio Network Interface:
• Wireless microphone systems
• Wired installed microphones (logic functions supported by block connector model)
• Computers or mobile devices used for presentations
• Other playback devices
Output: Dante™ Digital Audio
Connect the Dante™ output to a network switch with a network cable. A single network cable delivers all 4 channels of audio onto the network, and carries
Power over Ethernet (PoE) to power the device. Use Dante™ Controller to route audio channels from the Audio Network Interface to the appropriate network
destination. Any of the signals may be routed to multiple destinations, to provide local reinforcement while simultaneously delivering audio to the far end.
Summing
The Audio Network Interface provides channel summing to combine input signals and send them over a single Dante™ channel. This makes it possible to send
all channels to a device with a limited amount of Dante™ receiver channels. Mixer functionality does not change; audio channels are simply sent as one combined
signal.
Note:When summing is enabled, a limiter is activated to prevent signal overloading. The limiter never applies to the direct outputs, and only affects the summed
signal.
To enable, select one of the summing options in the toolbar at the top of the mixer in the channels tab.

Example Scenario
A common application that requires summing is a video conference where there are multiple microphones. When a device (a computer running conferencing
software and Dante™ Virtual Soundcard, for example) only supports 1 or 2 Dante™ receiver channels, the Audio Network Interface combines the input signals
to transmit as a single Dante™ channel.

① Summed analog audio channels
When the 4 analog audio channels are summed, each of the Dante™ transmit channels includes all of the input signals.
② Single Dante audio channel
One Dante™ signal is sent over the network, which contains all 4 summed channels.
③ Connection to computer
A computer that is running limited number of Dante™ channels with Dante™ Virtual Soundcard, receives all audio on a single channel. This audio is sent to
the far end.
Encryption
Audio is encrypted with the Advanced Encryption Standard ( AES -256), as specified by the US Government National Institute of Standards and Technology
(NIST) publication FIPS-197. Shure devices that support encryption require a passphrase to make a connection. Encryption is not supported with third-party
devices.
To activate encryption:
1. Open the 设置 menu and select the 總述 tab.
2. Select the Enable Encryption checkbox.
3. Enter a passphrase. All devices must use the same passphrase to establish an encrypted connection.
Important: For encryption to work:
• Encryption must be universally enabled or disabled on all connected Shure devices
• AES67 must be disabled in Dante Controller to turn encryption on or off. AES67 encryption is currently not supported.

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.
1. Set the Metering to Pre-fader in the toolbar at the top of the workspace to monitor analog signal levels
2. Select the analog gain value to open the fader
3. Match the analog gain setting to the incoming signal level. Use the gain range markers on the fader to apply the appropriate amount of gain:
Gain RangeSource Level
0 to +9 dBLine (+4 dBu)
+9 to +21 dBAuxiliary (-10 dBV)
+21 to +51 dBMicrophone (varies)
4. The meters should peak between -18 and -9 dB.
Note: Leaving some additional headroom is a recommended to prevent clipping if mobile devices will be plugged into particular channels.
Adjusting Output Levels
Output Levels
Output levels are controlled by the Digital Gain (dB) fader. Always adjust the input gain (analog) before the output gain (digital). In most cases, setting the analog
gain correctly results in an appropriate output level. Sources that have a quiet signal, such as a microphone with low sensitivity, may need someDigital Gain
(dB) applied. If adjustments to the Digital Gain (dB) fader are required, follow these steps:
1. Set the Metering to Post-fader in the toolbar at the top of the workspace.
2. Adjust theDigital Gain (dB) fader as needed.
3. If using summing, use the Digital Gain (dB) faders to mix the channel levels.
Metering Options (Pre-fader and Post-fader)
Metering
There are two modes for monitoring, for input and output signals to be monitored separately.

Pre-fader
Post-fader
Pre-Fader (Analog Input Level)
Pre-fader metering displays the signal level before it reaches the digital gain fader, so that input signal levels can be optimized for each channel. Analog gain
adjustments affect the meter when set to pre-fader, but the digital gain adjustments do not.
Important: If the incoming signal is adjustable (wireless microphone systems, for example), make sure it is at the nominal level before adjusting the analog gain
on the Audio Network Interface.
Post-Fader (Digital Output Level)
Post-fader metering displays the signal level at the very end of the signal chain, which includes both the analog and digital gain. Use this setting to meter the
levels that are being sent over the Dante™ network.

Logic and Control Systems
Logic Applications
The block connecter model variation (ANI4IN-BLOCK) features three logic signal connections. Logic signals are converted into Ethernet command strings and
sent and received by any device (such as an echo canceller or control system) that supports Ethernet command strings.
