Audio Network Interface (Ani); Front Panel - Shure MXW Series User Manual

Hardware Description

Audio Network Interface (ANI)

The ANI performs the following functions:
• Converts digital audio from the network into analog audio to connect to a sound reinforcement system or recording device
• Four-port gigabit switch can connect an entire MXW system (up to eight channels) and power the MXW access point
• Provides analog input(s) to route audio to the microphones for personal monitoring.
• Front-panel interface provides status indicators and access to basic system controls.
• Hosts an embedded web server that provides an interface for monitoring and control of the device.
MXWANI8 Eight channel outputs; two input channels
MXWANI4 Four channel outputs; one input channel

Front Panel

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
• 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 Mute/unmute a channel. Mute is indicated by the
(3 seconds) 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
jack for monitoring or troubleshooting.
HEADPHONE
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

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
Power Green
Ethernet Green

Network Flashing
Audio Green
Off
Lockout Red
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.
⑩ ⑪
Status
Unit is powered on.
Connected to an Ethernet device.
All connected receive channels are OK
(receiving digital audio as expected).
One or more connected receive channels
experiencing a subscription error or is
unresolved (transmitting device is off,
disconnected, renamed or has incorrect
network setting).
No receive channels connected (routing has
not been established).
Front panel gain and mute controls are locked.
The LED will blink when a button is pressed
while the hardware is locked. A channel can
still be selected for headphone monitoring.
