ANI4IN
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.
Model Variations
ANI4IN-XLR: Four XLR inputs (balanced audio only)
ANI4IN-BLOCK: Four 6-pin block connector inputs (balanced audio and logic connections)

①Input Signal Clip Indicators
Each indicator corresponds to a single input channel. If the LED turns red, attenuate the level from the source device to
prevent clipping at the input stage. Analog and digital gain adjustments are made through the web application.
LED State Audio Signal Level
Off less than -60 dBFS
Green -59 dBFS to -24 dBFS
Yellow -23 dBFS to -1 dBFS
Red 0 dBFS or more
②Audio and Logic Inputs
Note: Logic connections are only featured on the block connector version
Block Inputs: Each input receives balanced audio and logic signals. Pin assignments are as follows:
Audio +
Audio -
Audio ground
switch Logic Mute (sent from microphone)
led Logic LED (received by microphone)

⑤Dante Network Port
Connects to a network switch to send Dante audio, while receiving Power over Ethernet (PoE) and data from the control
software. See the Dante and networking section for additional information.
⑥Reset Button
Resets the device settings back to the factory default.
Power Over Ethernet (PoE)
This device requires PoE to operate. It is compatible with both Class 0 and Class 3 PoE sources.
Power over Ethernet is delivered in one of the following ways:
A network switch that provides PoE
A PoE injector device
Installation and Rack Mounting
Two mounting solutions are available for installing the Audio Network Interface:
CRT1 19" Rack Tray (optional accessory): Supports up to 3 devices; mountable in a rack or under a table
Single-unit Mounting Tray (included accessory): Supports a single device for mounting under a table
Securing the Devices
Use the included screws from the mounting hardware kit to secure the Audio Network Interfaces. Audio Network Interfaces can
be mounted to face either direction. Insert the screws from the bottom in the appropriate holes, according to the following dia
grams:

Align the holes as shown for securing a single device in the single-unit mounting tray
Align the holes as shown for securing up to 3 devices in the 19" rack tray.
Rack Ear Configuration
A combination of up to 3 Audio Network Interfaces can be mounted in a single 19-inch rack space. The adjustable rack ears
support mounting in a standard equipment rack or underneath a table.
Standard 19" Rack Mount
Align the ears with the mounting holes pointed forward.
Install the 3 screws that hold the ear to the tray as shown.

Reset
The reset button is located inside a small hole in the rear panel. Use a paperclip or other small tool to press the button.
There are two hardware reset functions:
Network reset (press button for 4-8 seconds)
Resets all Shure control and audio network IP settings to factory defaults
Full factory reset (press button for longer than 8 seconds)
Restores all network and Designer settings to the factory defaults.
Software Reset Options
To simply revert settings without a complete hardware reset, use one of the following options:
Reboot Device:Power-cycles the device as if it were unplugged from the network. All settings are retained when the device is
rebooted.
Default Settings: To revert audio settings back to the factory configuration (excluding Device Name, IP Settings, and Pass
words), select Load Preset and choose the default settings preset.
Levels and Metering
Adjusting 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 incre
ments, with up to 51 dB total gain.
Set the Metering to Pre-fader in the toolbar at the top of the workspace to monitor analog signal levels
Select the analog gain value to open the fader
Match the analog gain setting to the incoming signal level. Use the gain range markers on the fader to apply the appro
priate amount of gain:
Source Level Gain Range
Line (+4 dBu) 0 to +9 dB
Auxiliary (-10 dBV) +9 to +21 dB
Microphone (varies) +21 to +51 dB
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 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 re
quired, follow these steps:
Set the Metering to Post-fader in the toolbar at the top of the workspace.
Adjust theDigital Gain (dB) fader as needed.
If using summing, use the Digital Gain (dB) faders to mix the channel levels.
Metering Options (Pre-fader and Post-fader)
There are two modes for monitoring, for input and output signals to be monitored separately.
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.
Mute Sync
Mute sync ensures that all connected devices in a conferencing system mute or unmute at the same time and at the correct
point in the signal path. Mute status is synchronized in the devices using logic signals or USB connections.
To use mute sync, make sure logic is enabled on all devices.
Designer's Optimize workflow configures all necessary mute sync settings for you.
Compatible Shure logic devices:
P300 (Also mutes supported soft codecs connected by USB)
ANIUSB-MATRIX (Also mutes supported soft codecs connected by USB)

ate entirely on a Dante network. Additional hardware, including network switches, computers, loudspeakers, and audio proces
sors are described in the hardware component index.
