General Description
The MXW Audio Network Interface (ANI) is a digital-to-analog breakout box
with a built-in gigabit network switch. It converts digital audio from a network
into analog signals for signal processing or amplification. Input channels add
analog audio to the network and can be routed to MXW microphones as a
translation channel or for personal monitoring.
The front panel includes channel status indicators and controls for gain and
mute adjustment. Monitoring features include a headphone jack and dBFS
output meter. A computer can remotely monitor and control a networked unit
from a built-in webserver interface (GUI).
Features
• Converts digital audio from the Dante network into analog output signals
• Built-in gigabit network switch with four ports
• Input channels add analog audio to the digital audio network
• Front-panel gain and mute controls
• Headphone jack for monitoring and troubleshooting
• Monitor LEDs display channel status and output levels

The ANI is a part of the Microflex Wireless Series (MXW), a complete
solution for meeting room and presentation applications. Developed with
Dantetm technology by Audinate, digital audio is routed over standard IP
equipment across a network of access points, digital-to-analog converters
and computers. Access points mount to a ceiling or wall and communicate
wirelessly with the microphones to add audio to the network. RF
coordination is automatic and continuous, offering worry-free wireless audio
transmission for every event.
① Power
Connect the power cable from
the ANI to an AC power supply.
Turn on the power switch.
② Audio Outputs
Connect to a signal processor,
amplifier or recording system.
③ Audio Inputs
Connect to a line- or aux-level
analog audio source to add it to
the digital network.
④ Network Port 1 (PoE)
Connect to MXWAPT Access
Point to provide Power over
Ethernet (PoE) and networked
audio and control.
⑤ Network Port 2
Connect to an additional
charger, ANI or computer to
provide networked audio and/or
control.
⑥ Network Port 3
Connect to an additional
charger, ANI or computer to
provide networked audio and/or
control.
⑦ Network Port 4 (Uplink)
Connect to a corporate network
for access to the control
software. (When Port 4 Uplink
mode is enabled, Dante Audio
and Controller data are excluded
from this port.)
MXW Components
① Microflex Microphones
The MXW microphones are available in gooseneck, boundary,
handheld and bodypack models.
② Access Point Transceiver (APT)
Sleek and unobtrusive, the APT mounts to a wall or ceiling to provide
direct, line-of-sight wireless connection to the microphones. The APT
automatically manages the RF spectrum, ensuring consistent, stable
audio transport from the microphones to the digital network.
③ Networked Charging Station (NCS)
The charger recharges microphones without battery removal and
networks battery status for remote monitoring. The charger also
initiates the linking of microphones to an APT, enabling wireless audio
transmission.
④ Audio Network Interface (ANI)
The ANI converts digital audio from the network into analog audio to
send to a signal processor or amplifier.
⑤ Control Software
The control software allows comprehensive remote management of
the MXW system. It operates in a web browser when networked to a
computer.

① Input Channels
Adds analog line- or aux-level signals to the digital network. When the
device is associated to an MXW Group, inputs are automatically routed
to Linked microphone channels (Input A to channels 1-4; Input B to 5-8).
② Output Channels
Converts digital network audio to an analog output for each channel.
When associated to an MXW group, access point channels are
automatically routed to the outputs of the ANI.
③ Channel Selector
Selects a channel to perform the following functions:
Action Function
Single Press • Listen to that channel at the headphone jack
• Display and adjust the channel output level and
attenuation
• Monitor output signal on the level meter
Press and Hold
(3 seconds)
Mute/unmute a channel. Mute is indicated by the
mute LED.
④ Selected Channel LED
Illuminates when a channel is selected.
⑤ Signal Strength LED (sig/clip)
Indicates audio signal strength for each channel:
- Green = Normal
- Amber = Strong
- Red = Clipping (to eliminate clipping, attenuate the signal level at the audio
source)
⑥ Mute LED
Illuminates red when the channel output is muted (hold its channel
select button for 3 seconds). A muted channel is still routed to the
HEADPHONE jack for monitoring or troubleshooting.
⑦ Input Level Selector
Set the selected channel to line- or aux-level to match the input signal.
⑧ Output Level Selector
Set the selected channel to an output level that matches the connecting
device:
- line: +4 dBu
- aux: -10 dBV
- mic: -30 dBV
Front Panel
⑨ Output Attenuation Control
Use the up/down buttons to attenuate the channel output from 0 dB (no
attenuation) to -24 dB in 1 dB increments, and from -24 to -78 in 3 dB
increments.
⑩ Level Meter
Displays a selected channel's audio level in dBFS. It is good practice to
use -18 dBFS on the output meter as an approximation of 0 VU on an
analog meter.
⑪ Hardware Status LEDs
Indicate the status of the hardware:
LED Color Status
Power Green Unit is powered on.
Ethernet Green Connected to an Ethernet device.
Network
Audio
Green All connected receive channels are OK
(receiving digital audio as expected).
Flashing
Green
One or more connected receive channels
experiencing a subscription error or is
unresolved (transmitting device is off,
disconnected, renamed or has incorrect
network setting).
Off No receive channels connected (routing has
not been established).
Lockout Red Front panel gain and mute controls are locked.
The LED will blink when a button is pressed
while the hardware is locked.
⑫ Headphone Volume Knob
Adjusts the volume to the headphone output.
⑬ Headphone Output
1/4" (6.35 mm) output jack for monitoring audio going to and from the
digital audio network.
Note: Audio is present only when the unit is connected to a digital audio
network.

⑨ Network Interface
Four-port gigabit switch for connecting components together for a single
MXW Group, or for connecting multiple devices to a larger digital audio
network. The following is a description of each port:
Port Description
Port 1
(PoE)
Provides Power over Ethernet (PoE) for the Shure
access point and functions as a standard gigabit port.
Ports 2
and 3
Standard gigabit ports enable the connection of another
MXW network, additional MXWANIs, a MXWNCS
charging stations or an external control system.
Port 4
(Uplink)
• Normal mode (default): this port functions the same as
ports 2 and 3.
• Uplink Mode: only transports control data. This
mode blocks network audio and data for Shure Web
Discovery Application, Dante Controller and Dante
Virtual Soundcard.
Back Panel
① AC Power
IEC connector 100 - 240 V AC.
② Power Switch
Powers the unit on or off.
③ Output Block Connectors (1-8)
Three-pin, low-voltage differential connector provides a line-, aux- or
mic-level analog output for each channel.
④ Chassis Ground (1-8)
Use to directly ground the cable shield to the chassis.
⑤ Input Block Connectors (A,B)
Three-pin, low-voltage differential input connector adds line- or aux-
level analog signals to the digital network.
Note: This input is meant for balanced connection. If an unbalanced source is
used, such as an IPOD or MP3 player, only use pins 1 (signal) and 3 (ground) of
the block connector. See Specifications sections for wiring diagrams.
⑥ Reset Button
Press and hold the button for five seconds to reboot the device with
factory default settings.
⑦ Ethernet Status LED (Green)
- Off = no network link
- On = network link established
- Flashing = network link active
