Example Scenario: Connecting a Three-Way Call
Near-end audio from Dante microphones (Shure MXA 310) and the mobile phone are both routed to the video
codec and sent to the far end. The mobile phone is simply carrying the audio from the remote caller -- its built-in
microphone and speaker are disabled.
Far-end audio from the video codec is routed to a powered loudspeaker or amplifier (analog or Dante-enabled). It
is also routed to the mobile phone (connected to the P300) to relay the signal to the remote caller.
The remote caller (far end) receives audio from both the near-end and far-end locations. The P300 connects all
locations by routing both near and far-end audio sources through the mobile output. The audio from the remote
caller is routed to the mobile input, and then sent to the loudspeakers in the near-end room and through the video
codec to the far-end room.

Mute and Fader Groups
Mute Groups
Check the Mute group box to add the channel to a group. Muting any channel with­
in the Mute group mutes all channels in the group.
Fader Groups
Check the Fader group box to add the channel to a group. All faders within the
group are linked, and move together when a single fader is adjusted.
Custom Presets
Use presets to quickly save and recall settings. Up to 10 presets can be stored on each device to match various
signal processing requirements, room types, and microphones used. A preset saves all device settings except for
the Device Name, IP Settings, and Passwords. Importing and exporting presets into new installations saves time
and improves workflow. When a preset is selected, the name displays above the preset menu. If changes are
made, an asterisk appears next to the name.
Note: Use the default settings preset to revert to the factory configuration (excludes Device Name, IP Settings,
and Passwords).

Logic
The enable logic feature on all Dante input channels makes it possible to use a microphone mute button to send a
mute command to the P300. The button on the microphone triggers the P300 to mute the audio after the acoustic
echo canceller and the automatic mixer, so the processors continue operating when the system needs to be mut­
ed. In many configurations, this eliminates the need for an external control system, which is often needed in a sys­
tem with an acoustic echo canceller. Enabling logic on any channel activates the setting on all Dante channels
(1-8).
25/96
Safety Information
Shure Incorporated
This feature works with Shure MXA310 table array microphones and MXA910 ceiling array microphones, or with
the Shure ANI4IN network interface (when paired with analog microphones that support logic functionality).
Note: the MXA910 requires an MXA310 or control system to send the logic signal to the P300.
The automixer mix out channel in the P300 web application has a mute button, which responds to the logic control
device (MXA310 or control system) when logic is enabled. When the automix mute button is pressed in the P300
web application, the LED on the microphone (MXA910 or MXA310) changes to show that the system is muted.
Important MXA310 microphone configuration steps:
• The microphone logic setting must be set to external control in the MXA310 web application. This must be done
for each microphone.
• If using the automix out channel from the MXA310 (instead of sending 4 individual MXA310 channels to the
P300 automixer), the MXA310 LED must be set to Ring instead of Segments.
Adjusting Input levels
Levels for Dante, analog, USB, and mobile channels are adjustable in the Input tab and in the schematic view.
To monitor input levels before they reach the P300, set the metering to pre­fader in the settings menu. When ad­
justing the faders, set metering to post-fader.
Digital Sources (Dante and USB)
1. Check the source level before it reaches the P300:
◦ Verify that the networked microphones or other Dante sources are operating at nominal output levels.
◦ Set USB volume on the computer to the maximum setting if the volume control is accessible.
◦ Levels for Microflex Advance™ and Microflex Wireless microphones are adjustable through their web appli­
cation.
2. Adjust the digital gain in the P300 web application:
◦ Use the faders or manually enter a gain value.
◦ The digital gain adjusts the level of the signal before it reaches the matrix mixer.
◦ Mix the levels as high as possible without the loudest channel reaching the peak level (0 dB) on the meter.
Note: The matrix mixer provides crosspoint gain, to adjust separate submixes for different outputs.
Analog Sources (Line Inputs)
Before you begin, verify that levels from the analog devices with adjustable output levels are operating at nominal
levels. The fader adjusts the digital gain before the signal reaches the matrix mixer.
1. Match the analog input level setting according to the incoming signal level:
Line (+4 dBu)
26/96
Safety Information
Shure Incorporated
Aux (-10 dBV)
2. Use the fader (digital gain) to adjust the mix going to the USB or Dante output channels.
Mobile Devices
The mobile device input gain is optimized for most devices when the fader is set at zero, to provide adequate vol­
ume with sufficient headroom. As a general target, the audio signal received by the P300 from the phone should
reach an average level of approximately -24 dBFS.
1. Set a phone at approximately 50% volume
2. Make a test call to verify the following:
◦ Can the far-end talker be clearly heard?
◦ Can the far-end talker clearly hear audio from the near end?
If the signal being sent to the far­end is quiet, verify the gain levels for the near­end microphones and the automix­
er have been properly set.
Adjusting Output Levels
Tip: Set the output metering in the settings menu to ensure accurate metering.
Adjust faders in the Outputs section as high as necessary, but make sure to avoid clipping (when the signal reach­
es 0 dBFS). Always adjust the input gain and crosspoint gain in the matrix mixer before the output gain.
Analog output level:Select Line, Aux, or Mic level output signal to match the sensitivity of the receiving device.
Pre- and Post-Fader Metering
The two metering modes allow you to monitor signal levels before and after gain stages.
Input Metering
When set to pre-gain, the meter displays the signal level at the inputs of the P300. If signals are too low or clip­
ping, adjust them at the source.
When set to post-gain, the meter is affected by gain adjustments from the input channel faders. This does not in­
clude automatic gain control or any other processing.
Output Metering
When set to pre-gain, the meter displays signal levels after gain has been applied at the input stage, but before
the output faders. This includes input faders, digital signal processing blocks, automixing, and crosspoint gain.
27/96
Safety Information
Shure Incorporated
When set to post-gain, the meter indicated the signal sent to each output. This includes gain adjustments made
on the output faders .
Automatic Gain Control (AGC)
Automatic gain control adjusts channel levels to ensure consistent volume for all talkers, in all scenarios. For qui­
eter voices, it increases gain; for louder voices, it attenuates the signal.
The automatic gain control is post­fader, and adjusts the channel level after the input level has been adjusted. En­
able it on channels where the distance between the talker and the microphone may vary, or in rooms where many
different people will use the conferencing system.
Target Level (dBFS)
Use -30 dBFS as a starting point to ensure adequate headroom, and adjust if nec­
essary. This represents the RMS (average) level, which is different from setting the
input fader according to peak levels to avoid clipping.
Maximum Boost ( dB)
Sets the maximum amount of gain that can be applied
Maximum Cut ( dB)
Sets the maximum attenuation that can be applied
Tip: Use the boost/cut meter to monitor the amount of gain added or subtracted from the signal. If this meter is al­
ways reaching the maximum boost or cut level, consider adjusting the input fader so the signal is closer to the tar­
get level.
Parametric Equalizer
Maximize audio quality by adjusting the frequency response with the parametric equalizer. Use the input equaliz­
ers to make adjustments to specific channels, while using the output equalizers to adjust frequency response of all
signals that are summed through a given output.
Common equalizer applications:
• Improve speech intelligibility
• Reduce noise from HVAC systems or video projectors
• Reduce room irregularities
• Adjust frequency response for reinforcement systems
2-Band Equalizers
Adjust filter settings by manipulating the icons in the frequency response graph, or by entering numeric values.
Disable a filter using the check-box next to the filter.

EQ Application
Suggested Settings
Reduce flutter echoes and sibilance
Identify the specific frequency range that "excites" the
room:
1. Set a narrow Q value
2. Increase the gain to between +10 and +15 dB, and
then experiment with frequencies between 1 kHz
and 6 kHz to pinpoint the range of flutter echoes or
sibilance
3. Reduce the gain at the identified frequency (start
between -3 and -6 dB) to minimize the unwanted
room sound
Reduce hollow, resonant room sound
Identify the specific frequency range that "excites" the
room:
1. Set a narrow Q value
2. Increase the gain to between +10 and +15 dB, and
then experiment with frequencies between 300 Hz
and 900 Hz to pinpoint the resonant frequency
3. Reduce the gain at the identified frequency (start
between -3 and -6 dB) to minimize the unwanted
room sound
Acoustic Echo Cancellation
In audio conferencing, a far-end talker may hear their voice echo as a result of a near-end microphone capturing
audio from loudspeakers. Acoustic Echo Cancellation is a DSP algorithm which identifies and eliminates echoes to
deliver clear, uninterrupted speech. The P300 features 8 channels of acoustic echo cancellation, with independent
processing on each channel for maximum effectiveness. Use the following tips when setting up a system:
• Optimize the acoustic environment, when possible: avoid pointing speakers directly at microphones, reduce
speaker volume, and position speakers farther from microphones.
• If connecting to a Shure MXA910, disable the Echo Reduction on the microphone.
Training the Acoustic Echo Cancellation
Training is the process where the AEC optimizes processing based on the acoustic environment. It only trains
when far-end audio is present and near-end talkers are quiet. The AEC is constantly adapting, so if the acoustic
environment changes, the AEC automatically adjusts.
31/96
Safety Information
Shure Incorporated
Adjusting Settings
To adjust acoustic echo cancellation settings, open the AEC menu in the schematic view or inputs tab.
Reference Meter
Use the reference meter to visually verify the reference signal is present.
ERLE
Echo reduction loss enhancement displays the dB level of signal reduction (the
amount of echo being removed). If connected properly, the ERLE meter activity
generally corresponds to the reference meter.
Reference
Select the channel that carries audio to the loudspeakers as the reference. Analog
- To Speaker is the most commonly used channel, for configurations with an ana­
log loudspeaker system or a display with a built-in speaker.
Note: Selecting a reference on any channel applies that same reference to all
channels with AEC.
Non-linear Processing
The primary component of the acoustic echo canceller is an adaptive filter. Non­lin­
ear processing supplements the adaptive filter to remove any residual echo caused
by acoustic irregularities or changes in the environment. Use the lowest possible
setting that is effective in your room.
Low: Use in rooms with controlled acoustics and minimal echoes. This setting pro­
vides the most natural sound.
Medium: Use in typical rooms as a starting point. If echo artifacts appear, try using
the high setting.
High: Use to provide the strongest echo reduction in rooms with bad acoustics, or
in situations where the echo path frequently changes.
Noise Reduction
Noise reduction significantly reduces the amount of noise in the signal caused by projectors, HVAC systems, or
other environmental noise. It is a dynamic processor, which calculates the noise floor in the room and removes
noise throughout the entire spectrum with maximum transparency.
Settings
The noise reduction setting (low, medium, or high) represents the amount of reduction in dB. Use the lowest pos­
sible setting that effectively lowers noise in the room.
Compressor
Use the compressor to control the dynamic range of automixer output signal.
32/96
Safety Information
Shure Incorporated
Threshold
When the audio signal exceeds the threshold value, the level is attenuated to pre­
vent unwanted spikes in the output signal. The amount of attenuation is deter­
mined by the ratio value. Perform a soundcheck and set the threshold 3-6 dB
above average talker levels, so the compressor only attenuates unexpected loud
sounds.
Ratio
The ratio controls how much the signal is attenuated when it exceeds the threshold
value. Higher ratios provide stronger attenuation. A lower ratio of 2:1 means that
for every 2 dB the signal exceeds the threshold, the output signal will only exceed
the threshold by 1 dB. A higher ratio of 10:1 means a loud sound that exceeds the
threshold by 10 dB will only exceed the threshold by 1 dB, effectively reducing the
signal by 9 dB.
Delay
Use the delay feature on the analog and USB outputs to synchronize audio and video. When a video system intro­
duces latency (where you hear someone speak, and their mouth moves later), simply add delay to the analog out­
puts to align with the video. Delay can also be used in larger rooms to align the arrival time or phase between mul­
tiple speakers.
The delay is measured in milliseconds. If there is a significant difference between audio and video, start by using
larger intervals of delay time (500-1000 ms). When it is closer to full synchronization, use smaller intervals to finetune.
The USB output channel features delay to ensure the near-end camera and near-end audio are synchronized.
Automix Modes
Gating
Gating mode delivers fast­acting, seamless channel gating and consistent perceived ambient sound levels. Off­at­
tenuation in this mode is fixed at -20 dB per channel, regardless of the number of open channels.
Gain Sharing
Gain sharing mode dynamically balances system gain between open and closed channels. The system gain re­
mains consistent by distributing gain across channels to equal one open channel. The scaled gain structure helps
to reduce noise when there is a high channel count. When fewer channels are used, the lower off­attenuation pro­
vides transparent gating.
33/96
Safety Information
Shure Incorporated
Manual
Manual mode sums all active tracks and sends the summed signal over a single Dante output. This provides the
option to route an individual signal for reinforcement or recording, without enabling automixing. The settings from
the faders in the standard monitoring view apply to the summed output.
Automix Settings
Leave Last Mic On
Keeps the most recently used microphone channel active. The purpose of this fea­
ture is to keep natural room sound in the signal so that meeting participants on the
far end know the audio signal has not been interrupted.
Gating Sensitivity
Changes the threshold of the level at which the gate is opened
Off Attenuation
Sets the level of signal reduction when a channel is not active
Hold Time
Sets the duration for which the channel remains open after the level drops below
the gate threshold
Maximum Open Chan­
nels
Sets the maximum number of simultaneously active channels
Priority
When selected, this channel gate activates regardless of the number of maximum
open channels.
Always On
When selected, this channel will always be active.
Gate Inhibit
Enable gate inhibit to prevent far-end audio from gating on near-end microphone
channels.
1. Make sure all input gain levels are properly adjusted and all other automixer
settings are configured.
2. Disable Leave last mic on.
3. Perform a test call with the far end to adjust the gate inhibitor fader. Increase
the fader level so that the far end indicator turns on, and far-end audio does not
gate the near-end automixer channels on.
4. Verify that near-end talkers still activate the automixer channels. If the channels
do not turn on, lower the gate inhibit fader.
5. Re-enable Leave last mic on if necessary.
Mic Optimization Mode
Select the microphone that is used with the automixer for best performance.

Use MXA910 or MXA310 when using a Shure MicroflexAdvance Ceiling Array or Table Array microphone.
Important: Disable the low-shelf filter (MXA910), low-cut filter (MXA310), and all equalization on the microphones
for the best performance with mic optimization.
Use the Off setting when using a Shure Microflex Wireless system, or traditional wired microphones. If using wired
microphones, use the Shure ANI4IN Network Interface to bring the microphones onto the Dante network.
Using A Password
All settings are configurable by default. To protect settings with a password, open the Settings menu and select the
General tab. In this screen, passwords can be created or changed.
Once a password has been set, a Read-Only option appears on the log-in screen. In Read-Only mode, device pa­
rameters can be viewed, but not edited. Device identification remains active.
Encryption
Audio is encrypted with the Advanced Encryption Standard ( AES ­256), as specified by the US Government Na­
tional 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 Settings menu and select the General 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 sup­
ported.
Networking and Dante
Networking Best Practices
Use the following best practices when setting up a network to ensure reliable communication:
• Always use a "star" network topology by connecting each component directly to the switch or router.
• Connect all Shure networked devices to the same network and set to the same subnet. This applies to all de­
vices that audio signals must be routed between (managed through Dante Controller). It is also required in or­
der to open the web application for a device.
35/96
Safety Information
Shure Incorporated
• Devices on separate networks require an audio processor or conferencing software to carry audio between
them. See the system planning and gear requirements section for network setup information and configuration
examples.
• Use only 1 DHCP server per network. Disable DHCP addressing on additional servers.
• Power on the switch and DHCP server prior to MXA equipment.
• To expand the network, use multiple Ethernet switches in a star topology.
• All devices must be at the same firmware revision level.
Network Audio and Shure Control Data
MicroflexAdvance devices transport two types of data over the network: Shure Control and Network Audio.
Shure Control
The Shure Control carries data for the control software operation, firmware updates and 3rd party control systems
(AMX, Crestron).
Network Audio
This network carries both the Dante digital audio and the control data for Dante Controller. The network audio re­
quires a wired, gigabit Ethernet connection to operate.

Configuring IP Settings
IP configurations are managed through the web application. By default, they are set to Automatic (DHCP) mode.
DHCP mode enables the devices to accept IP settings from a DHCP server, or automatically fall back to Link-Local
settings when no DHCP is available. IP addresses may also be manually set.
36/96
Safety Information
Shure Incorporated
To configure the IP properties, follow these steps:
1. Open the web application.
2. Go to the Settings tab and select Network.
3. Select Auto or Manual. If Auto is used, addresses will be automatically assigned. For Manual setup, follow the
instructions on manual configuration.
Manually Assigning Static IP Address
To manually assign IP addresses, follow these steps:
1. Open the web application.
2. Go to the Settings tab and select Network.
3. Select Manual as the Configure IP setting.
4. Enter the IP settings.
Operating the Control Software over Wi-Fi
When operating the web application over Wi­Fi, it’s important to set up the wireless router properly for best perfor­
mance. The system employs several standard-based protocols that rely on multicast. Wi-Fi treats broadcast and
multicast packets differently than general packets for backward compatibility reasons. In some cases, the Wi-Fi
router will limit the multicast packet transmission rate to a value that is too slow for web application to properly op­
erate.
Wi-Fi routers typically support 802.11b, 802.11a/g, and/or 802.11n standards. By default, many Wi-Fi routers are
configured to allow older 802.11b devices to operate over the network. In this configuration, these routers will auto­
matically limit the multicast data rates (or sometimes referred to as ‘basic rate’, or ‘management rate’) to 1­2Mbps.
Note: A Wi-Fi connection can only be used for the control software. Network audio cannot be transmitted over WiFi.
Tip: For larger wireless microphone configurations, it’s recommended to increase the multicast transmission rate
to provide adequate bandwidth.
Important: For best performance, use a Wi-Fi router that does not limit the multicast rate to 1-2 Mbps.
Shure recommends the following Wi-Fi router brands:
• Cisco
• Linksys
• Apple

Digital Audio Networking
Dantetm digital audio is carried over standard Ethernet and operates using standard Internet Protocols. Dante pro­
vides low latency, tight clock synchronization, and high Quality-of-Service (QoS) to provide reliable audio transport
to a variety of Dante devices. Dante audio can coexist safely on the same network as IT and control data, or can
be configured to use a dedicated network.
Switch Recommendations for Dante Networking
In addition to the basic networking requirements, Dante audio networks should use a Gigabit network switch or
router with the following features:
• Gigabit ports
• Quality of Service (QoS) with 4 queues
• Diffserv (DSCP) QoS, with strict priority
• Recommended: A managed switch to provide detailed information about the operation of each network link (port
speed, error counters, bandwidth used)
Setting Latency
Latency is the amount of time for a signal to travel across the system to the outputs of a device. To account for
variances in latency time between devices and channels, Dante has a predetermined selection of latency settings.
When the same setting is selected, it ensures that all Dante devices on the network are in sync.
The latency setting for Dante devices should be set according to the number of switches in the network.
Use Audinate's Dante Controller software to change the latency setting.

AES67
AES67 is a networked audio standard that enables communication between hardware components which use dif­
ferent IP audio technologies. This Shure device supports AES67 for increased compatibility within networked sys­
tems for live sound, integrated installations, and broadcast applications.
The following information is critical when transmitting or receiving AES67 signals:
• Update Dante Controller software to the newest available version to ensure the AES67 configuration tab ap­
pears.
• Before turning encryption on or off in the Shure device’s web application, you must disable AES67 in Dante
Controller.
• AES67 cannot operate when the transmit and receive devices both support Dante.

Receiving Audio from a Device Using a Different Audio Net­
work Protocol
Third-party devices: When the hardware supports SAP, flows are identified in the routing software that the device
uses. Otherwise, to receive an AES67 flow, the AES67 session ID and IP address are required.
Shure devices: The transmitting device must support SAP. In Dante Controller, a transmit device (appears as an
IP address) can be routed like any other Dante device.
Packet Bridge
Packet bridge enables an external controller to obtain IP information from the control interface of a Shure device.
To access the packet bridge, an external controller must send a query packet over unicast UDP* to port 2203 on
the Dante interface of the Shure device.
1. Send a UDP packet with a minimum 1-byte payload .
Note: The maximum accepted payload 140 bytes. Any content is allowed.
2. The Shure device will send a response packet over unicast UDP to the controller, using a destination UDP port
identical to the source port of the query packet. The payload of the response packet follows this format:
Bytes
Content
0-3
IP address, as 32­bit unsigned integer in network or­
der
4-7
Subnet mask, as 32-bit unsigned integer in network
order
8-13
MAC address, as array of 6 bytes
Note: The Shure device should respond in less than one second on a typical network. If there is no response,
try sending the query again after verifying the destination IP address and port number.
*UDP: User Datagram Protocol
QoS (Quality of Service) Settings
QoS settings assign priorities to specific data packets on the network, ensuring reliable audio delivery on larger
networks with heavy traffic. This feature is available on most managed network switches. Although not required,
assigning QoS settings is recommended.
Note: Coordinate changes with the network administrator to avoid disrupting service.

P300 Command Strings
The device is connected via Ethernet to a control system, such as AMX, Crestron or Extron.
Connection: Ethernet (TCP/IP; select “Client” in the AMX/Crestron program)
Port: 2202
If using static IP addresses, the “ Shure Control” and the “Audio Network” settings must be set to manual in the
P300 web application ( Settings > Network ). Use the Control IP address for TCP/IP communication with Shure
devices.
Conventions
The device has 4 types of strings:
GET
Finds the status of a parameter. After the AMX/Crestron sends a GET command, the P300 responds with a RE­
PORT string
SET
Changes the status of a parameter. After the AMX/Crestron sends a SET command, the P300 will respond with a
REPORT string to indicate the new value of the parameter.
REP
When the P300 receives a GET or SET command, it will reply with a REPORT command to indicate the status of
the parameter. REPORT is also sent by the P300 when a parameter is changed on the P300 or through the web
application.
SAMPLE
Used for metering audio levels.
All messages sent and received are ASCII. Note that the level indicators and gain indicators are also in ASCII

AEC Reference/Gate Inhibit Reference
Example Scenario: Muting a System
The Acoustic Echo Canceler (AEC) and P300 automixer require constant audio signal from the microphone to op­
erate. Do NOT send commands to the microphone to mute locally. Instead, use logic communication between the
P300 and Microflex Advance devices. This allows the AEC to continue processing audio even while the system is
muted, and deliver the best results when the system is unmuted.
After logic functionality is set up between Shure devices, send the command from the control system to mute the
P300 automixer output. If set up correctly, the P300 automixer output will mute, and the microphone LED color will
change to indicate the system is muted.
Note: Although the MXA310 LED status shows the system is muted, the audio signal is still passed to the P300 to
allow continuous processing.

Crestron/AMX sends the mute command to the P300.
P300
The LED command to indicate mute state is sent from the P300 to the MXA310.
MXA310
The MXA310 sends audio to the P300 for continuous processing.
Required Steps for Logic Functionality
1. In the MXA310 web application, go to Configuration > Button Control , then set mode to Logic Out.
2. In the P300 web application, go to the Input tab and enable Logic for every channel routed from the MXA310
microphone. The device type appears at the bottom of the input channel strip.
Note: The MXA910 does not require set up for logic functionality.
➀ Mute Command
Crestron/AMX sends the mute command to the P300.
➁ LED Command
The P300 sends the LED command to the MXA310 so that the microphone LED color matches the system mute
state.
➂ Continuous Audio Signal
The MXA310 sends audio to the P300 for continuous processing. The system is muted from the P300 at the end
of the audio chain.

Best Practices for Muting:
➀ Mute Button:
Press the mute button on the Crestron/AMX panel.
➁ Crestron/AMX sends following command to P300:
< SET 21 AUTOMXR_MUTE TOGGLE >
Note: The TOGGLE command simplifies logic within the Crestron/AMX. ON/OFF commands can be used instead,
but supplemental processes must be implemented within the Crestron/AMX.
➂ P300 Automixer channels mute, and P300 sends following REPORT back to Crestron/
AMX:
< REP 21 AUTOMXR_MUTE ON >
This REPORT command can be used in various ways for button feedback on the control surface.

Problem
Solution
No audio
• Verify the ANIUSB-MATRIX is selected as the audio
device in the audio devices or properties panel on
the computer
• Audio channels must be routed to an output
through the matrix mixer
• Connections between devices must be established
in Dante Controller™ software
• Check cables
• Verify that input/output channels are not muted
• Check that fader levels are not set too low
• Make sure there is not an encryption error -- a
passphrase mismatch or encryption only enabled
on one device disrupts audio.
Cannot route Dante audio channels
Hardware does not power on
Install latest version of Dante Controller from Audi­
nate, available at www.audinate.com.
• The network switch must supply Power over Ether­
net. Otherwise, a PoE injector must be used
• Check network cables and connections
