P300 and Computer with Soft Codec

1. Connect the computer to the USB port on the P300.
2. Connect a powered loudspeaker or amplifier to the P300 analog output 2. In the matrix mixer, this is labeled Analog - To Speaker. You can also use Dante PoE loudspeakers connected to the network switch.
3. In Designer, go to Matrix mixer to make connections between devices. Some connections are established automatically.

   Required Matrix Mixer Connections:

   Input	Output
   Automix	USB output
   USB input	Analog - To Speaker or Dante output

4. In Schematic, right-click any AEC block and choose an AEC reference source. The reference source is Analog - To Speaker for analog loudspeakers, or one of the Dante outputs for Dante loudspeakers.
5. Adjust input and output levels using Designer and perform a sound check. Refer to the Help section for additional information.

Connecting a USB Device

The USB port connects the host computer to the entire room audio system, including microphones and loudspeakers.

When the P300 is connected for the first time, the computer recognizes it as a USB audio device. You may need to select it as the input/output (recording/playback) device to pass audio. Assign the P300 as the default device to ensure it passes audio every time it is plugged in. Refer to the manual for your computer to configure the audio settings.

Hardware Codec System

1. Connect the hardware codec audio output to the P300 analog input 1. In the matrix mixer, this is labeled Analog - From Codec.
2. Connect the hardware codec audio input to the P300 analog output 1. In the matrix mixer, this is labeled Analog - To Codec.
3. Connect a powered loudspeaker or amplifier to the P300 analog output 2. In the matrix mixer, this is labeled Analog - To Speaker. You can also use Dante PoE loudspeakers connected to the network switch.
4. In Designer, go to Matrix mixer to make connections between devices. Some connections are established automatically.

   Required Matrix Mixer Connections:

   Input	Output
   Automix	Analog - To codec
   Analog - From Codec	Analog - To Speaker or Dante output

6. Adjust input and output levels using Designer and perform a sound check. Refer to the Help section for additional information.

Mobile Phone System

In this example, when the phone is plugged in, the built-in microphone and speaker are disabled -- the phone simply carries the call. The MXA310 microphone captures near-end audio, and the loudspeaker delivers audio from the far end of the call.

1. Connect the phone to the P300 with a 1/8-inch TRRS cable.
2. Connect a powered loudspeaker or amplifier to the P300 analog output 2. In the matrix mixer, this is labeled Analog - To Speaker. You can also use Dante PoE loudspeakers connected to the network switch.
3. In Designer, go to Matrix mixer to make connections between devices. Some connections are established automatically.

   Required Matrix Mixer Connections:

   Input	Output
   Automix	Mobile output
   Mobile input	Analog - To Speaker or Dante output

5. Adjust input and output levels using Designer and perform a sound check. Refer to the Help section for additional information.

Mobile Connection Cable Requirements

A 1/8-inch TRRS cable is required to connect a phone to the P300. Avoid using cables with a metal flange, as it may create an electrical connection to the exterior of the phone and interrupt the signal.

To ensure proper operation, only use:

• Apple-approved cables
• Cables with a plastic or non-conductive flange

Note: If necessary, a TRS (tip/ring/sleeve) cable may be used to plug a stereo device into the P300, but the device will only be able to send audio to the P300. The Enable auto-mute feature on the mobile input channel must be turned off in this case.

Adjusting Settings

Right-click an input, output, or processing block to access the following options:

Per Channel

Copy / paste

Copy and paste settings between items. For example, set the equalizer curve on the USB output, and then use the same setting for the analog output. Or, copy the gain and mute status from one input channel to several others.

Mute / unmute

Mutes or activates the channel

Enable / disable

Turns processing on or off (does not apply to matrix mixer or automixer)

Edit

Opens the dialog to adjust parameters

Global (right-click in blank area)

Mute all inputs

Mutes all input channels

Mute all outputs

Mutes all output channels

Unmute all inputs

Unmutes all input channels

Unmute all outputs

Unmutes all output channels

Close all dialogs

Clears all open dialogs from the workspace

Customizing the Workspace

Create a custom environment to monitor and control a set of inputs, outputs, and processing blocks from a single screen. There are two ways to break out dialogs:

• Right click > edit
• Double-click the input, output, or processing block.

Open as many dialogs as you need to keep important controls available.

Metering and Audio Routing

A meter appears underneath each input and output to indicate signal levels (dBFS).

The lines connecting inputs and outputs to the matrix mixer appear colored when connections are established. When a signal is not routed, the line appears gray. Use these tools to troubleshoot audio signals and verify connections and levels.

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.

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 analog 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. Non-linear 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 provides 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.

Settings

The noise reduction setting (low, medium, or high) represents the amount of reduction in  dB. Use the lowest possible setting that effectively lowers noise in the room.

Crosspoint Gain

Crosspoint gain adjusts the gain between a specific input and output, to create separate submixes without changing input or output fader settings. Select the dB value at any crosspoint to open the gain adjustment panel.

Gain staging: Input fader > crosspoint gain > output fader

Routing Channels

Connect inputs and outputs by selecting the box where they intersect.

P300 Default Settings

The default configuration enables calling to multiple far ends with near-end Shure microphones. Connections are established for operating hardware codecs, software codecs, and mobile phones simultaneously.

Setting Up Mute Sync on the MXA310 and P300

Use this setup to mute the P300 by pressing the mute button on the MXA310. In the P300’s signal chain, muting happens after the DSP so that the AEC stays converged.

1. Open the P300 in Designer and go to Inputs.
2. On any channel strip, select Logic enable. This enables logic on all channels.
3. Open the MXA310 in Designer and go to Settings > Logic control.
4. Set the Mute control function to Logic out.
5. Go to Lights. Set the style to Ring.

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.
   • Adjust levels for Microflex^®Advance™ and Microflex Wireless microphones in their web applications.
2. Adjust the P300's input gain in Designer:
   • Use the faders or manually enter a gain value. This gain stage 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 tab lets you adjust crosspoint gain, which controls the levels for the separate submixes being sent to the different outputs.

Analog Sources

1. Check the source level before it reaches the P300, and set any analog device with adjustable output levels to a nominal level.
2. In Designer, choose Line (+4dBu) or Aux (-10dBV) to match the incoming signal level for each analog input channel.
3. Use each channel's fader to adjust the gain before it goes to the matrix mixer.

Mobile Devices

The mobile device input gain is optimized for most devices when the fader is set at 0 dB. It provides adequate volume 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 the phone to approximately 50% volume.
2. Set the input gain to 0 dB.
3. Make a test call to verify the following:
   • Can you clearly hear the far-end talker?
   • Can the far-end talker clearly hear audio from the near end?

If the signal being sent to the far end is too quiet, check and adjust the gain levels for the near-end microphones and the automixer.

Mute and Fader Groups

Parametric Equalizer (PEQ)

Maximize audio quality by adjusting the frequency response with the parametric equalizer (PEQ). Use the input equalizers 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

Note: If you're connecting a microphone that has a built-in equalizer (such as an MXA310), disable any EQ on the mic and use the P300's EQ instead.

Input Metering

• Pre-gain: Displays the pre-fader signal level. If signals are too low or clipping, adjust them at the source.
• Post-gain: Displays the post-fader signal level, so the meters reflect gain adjustments on input faders. This meter does not include automatic gain control or any other processing.

Output Metering

• Pre-gain: Displays signal levels after input gain has been applied, but before the output faders. This meter includes input faders, digital signal processing blocks, automixing, and crosspoint gain.
• Post-gain: Displays the post-fader signal level sent to each output. This meter includes gain adjustments made on the output faders.

Automix Settings

Note: Not all settings are available on all automixers.

Leave Last Mic On

Keeps the most recently used microphone channel active. The purpose of this feature 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 Channels

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.

Send to Mix

When selected, sends the channel to the automix channel.

Solo

Mutes all of the other channels

Automix Gain Meter

When enabled, changes gain meters to display automix gating in real time. Channels that gate open will display more gain than channels that are closed (attenuated) in the mix.

Mic Optimization Mode (P300 only)

Select the microphone that is used with the automixer for best performance. For best results, use Designer's Optimize workflow (this automatically selects the correct mic optimization mode).

Use the Off setting when using a Shure Microflex Wireless system, or traditional wired microphones.

Automixer Direct Out Tap Points

In the Automixer tab, use the menus below each channel to choose where the signal to the matrix mixer should come from.

All options include input channel gain, mute, solo, and PEQ.

Pre-Processing/Pre-Gate

Sends a signal without AEC, noise reduction, or AGC to the matrix mixer.

Post-Processing/Pre-Gate

Sends a signal with AEC and noise reduction but without automixer gating or AGC to the matrix mixer.

Post-Processing/Post-Gate

Sends a signal with automixer gating, AEC, and noise reduction but without AGC to the matrix mixer.

Pre-Processing/Post-Gate

Sends a signal with automixer gating but without AEC, noise reduction, or AGC to the matrix mixer.

Note: Direct out tap points are not available on all Shure automixers.

Networking Best Practices

When connecting Shure devices to a network, use the following best practices:

• Always use a "star" network topology by connecting each device directly to the switch or router.
• Connect all Shure networked devices to the same network and set to the same subnet.
• Allow all Shure software through the firewall on your computer.
• Use only 1 DHCP server per network. Disable DHCP addressing on additional servers.
• Power on the switch and DHCP server before powering on the Shure devices.
• To expand the network, use multiple switches in a star topology.
• All devices must be at the same firmware revision level.

Device IP Configuration

This Shure device uses 2 IP addresses: one for Shure control, and one for Dante audio and control.

• Shure control
  • Carries data for Shure control software, firmware updates, and third-party control systems (such as AMX or Crestron)
• Dante audio and control
  • Carries Dante digital audio and control data for Dante Controller
  • Requires a wired, gigabit Ethernet connection to operate

To access these settings in Designer, go to [Your device] > Settings > IP configuration.

Device IP Settings

Configure IP

Sets IP mode of the selected network interface:

• Auto (DHCP): For automatic assignment of IP addresses.
• Manual (Static): For Static IP addresses.

IP Settings

View and edit the IP Address, Subnet Mask, and Gateway for each network interface.

MAC Address

The network interface's unique identification.

Configuring IP Settings

IP configurations are managed in Shure Designer software. 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.

To configure the IP properties, follow these steps:

1. Open device's configuration window.
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 device's configuration window in Designer.
2. Go to the Settings tab and select Network.
3. Select Manual as the Configure IP setting.
4. Enter the IP settings.

Digital Audio Networking

Dante digital audio is carried over standard Ethernet and operates using standard internet protocols. Dante provides 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 and Cable Recommendations for Dante Networking

Switches and cables determine how well your audio network performs. Use high-quality switches and cables to make your audio network more reliable.

Network switches should have:

• Gigabit ports. 10/100 switches may work on small networks, but gigabit switches perform better.
• Power over Ethernet (PoE) or PoE+ ports for any devices that require power
• Management features to provide information about port speed, error counters, and bandwidth used
• Ability to switch off Energy Efficient Ethernet (EEE). EEE (also known as "Green Ethernet") may cause audio dropouts and problems with clock synchronization.
• Diffserv (DSCP) Quality of Service (QoS) with strict priority and 4 queues

Ethernet cables should be:

• Cat5e or better
• Shielded

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.

These latency values should be used as a starting point. To determine the exact latency to use for your setup, deploy the setup, send Dante audio between your devices, and measure the actual latency in your system using Audinate's Dante Controller software. Then round up to the nearest latency setting available, and use that one.

Use Audinate's Dante Controller software to change latency settings.

Pushing Device Names to the Dante Network

To send a device name to appear in Dante Controller, go to Settings>General and enter a Device Name. Select Push to Dante to send the name to appear on the network.

Note: names appear in Dante Controller with "-d" attached.

AES67

AES67 is a networked audio standard that enables communication between hardware components which use different IP audio technologies. This Shure device supports AES67 for increased compatibility within networked systems 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 appears.
• Before turning encryption on or off, you must disable AES67 in Dante Controller.
• AES67 cannot operate when the transmit and receive devices both support Dante.

  Shure Device Supports:	Device 2 Supports:	AES67 Compatibility
  Dante and AES67	Dante and AES67	No. Must use Dante.
  Dante and AES67	AES67 without Dante. Any other audio networking protocol is acceptable.	Yes

Separate Dante and AES67 flows can operate simultaneously. The total number of flows is determined by the maximum flow limit of the device.

Compatibility with Dante Domain Manager

This device is compatible with Dante Domain Manager software (DDM). DDM is network management software with user authentication, role-based security, and auditing features for Dante networks and Dante-enabled products.

Considerations for Shure devices controlled by DDM:

• When you add Shure devices to a Dante domain, set the local controller access to Read Write. Otherwise, you won't be able to access to Dante settings, perform a factory reset, or update device firmware.
• If the device and DDM can't communicate over the network for any reason, you won't be able to control Dante settings, perform a factory reset, or update device firmware. When the connection is reestablished, the device follows the policy set for it in the Dante domain.
• If Dante device lock is on, DDM is offline, or the configuration of the device is set to Prevent, some device settings are disabled. These include: Dante encryption, MXW association, AD4 Dante browse and Dante cue, and SCM820 linking.

See Dante Domain Manager's documentation for more information.

Note: Applies to firmware 4.1.x and newer.

Dante Flows for Shure Devices

Dante flows get created any time you route audio from one Dante device to another. One Dante flow can contain up to 4 audio channels. For example: sending all 5 available channels from an MXA310 to another device uses 2 Dante flows, because 1 flow can contain up to 4 channels.

Every Dante device has a specific number of transmit flows and receive flows. The number of flows is determined by Dante platform capabilities.

Unicast and multicast transmission settings also affect the number of Dante flows a device can send or receive. Using multicast transmission can help overcome unicast flow limitations.

Shure devices use different Dante platforms:

Learn more about Dante flows in our FAQs or from Audinate.

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 32-bit unsigned integer in network order
   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.

To assign QoS values, open the switch interface and use the following table to assign Dante^®-associated queue values.

• Assign the highest possible value (shown as 4 in this example) for time-critical PTP events
• Use descending priority values for each remaining packet.

Dante QoS Priority Values

Note: Switch management may vary by manufacturer and switch type. Consult the manufacturer's product guide for specific configuration details.

IP Ports and Protocols

Shure Control

*These ports must be open on the PC or control system to access the device through a firewall.

^†These protocols require multicast. Ensure multicast has been correctly configured for your network.

See Audinate's website for information about ports and protocols used by Dante audio.

Event Log

The event log provides a detailed account of activity from the moment the device is powered on. The log collects up to 1,000 activity entries and time-stamps them relative to the last power cycle. The entries are stored in the internal memory, and are not cleared when the device is power-cycled. The Export feature creates a CSV (comma separated values) document to save and sort the log data.
