How the Network Mute Button Works

The network mute button is a simple muting solution for rooms with no microphone on the table, for when the microphone has no mute button, or for when you need another way to control muting. Use Shure Designer software to link mute buttons to a compatible device.

You can link mute buttons to Shure microphones, DSPs, or audio network interfaces. When you link mute buttons to a DSP or audio network interface, any supported devices connected to the DSP or audio network interface match the button's mute status.

For example, in this room, 2 mute buttons are linked to a P300. Two MXA910 microphones are connected to the P300, and the P300 sends the near-end signal to a soft codec running on a computer. When you press one of the mute buttons, all connected devices show the correct mute status. The signal gets muted at the best point in the signal chain for DSP performance.

Two network mute buttons linked to a P300. Press a mute button, and devices connected to the P300 show the correct mute state.

Installing the Mute Button

The mute button fits in tables that are between 0.31 and 2.05 inches (8 to 52 mm) thick.

To get started, you will need:

  • Drill with 7/8 or 1 inch (22 or 25 mm) drill bit
  1. Drill a hole in the table. You can use a 7/8 or 1 inch (22 or 25 mm) drill bit, because the grommet accommodates both sizes. The mute button tube is 7/8 inches (22 mm) wide.

    Drilling a 22 or 25 mm hole in a table to install the MXA Network Mute Button.

  2. Insert the mute button tube into the hole.

    Inserting the MXA Network Mute Button into the drilled hole.

  3. Slide the grommet onto the tube so it's flush against the bottom of the table.
    • 7/8 inch (22 mm) hole: Grommet pointing down
    • 1 inch (25 mm) hole: Grommet pointing up

    Optional: Add 1 or more of the included spacers between the grommet and the base to help position the network port under the table. The spacers give you multiple network port positions.

    Install the network mute button grommet facing down for 22 mm holes. Install the grommet facing up for 25 mm holes.

  4. Slide the base onto the tube and tighten it by hand until it is snug against the table. You may want to hold the top of the mute button as you tighten the base to keep the mute icon correctly positioned on the table.

    Attach the network mute button base to the tube and tighten it by hand.

  5. Connect the 8-pin power cable to the power connector on the base.

    Diagram showing how to attach the 8-pin Molex cable to the Molex connector on the MXA network mute button.

  6. Connect a Cat5e (or better) Ethernet cable to the network port. Make sure the cable supplies Power over Ethernet from a network switch or PoE injector.

    Connect the Ethernet cable to the MXA Network Mute Button to supply power.

  7. Check that the mute button's light ring turns on after you plug in the Ethernet cable.
  8. To link the mute button to other devices and control other settings, open it in Shure Designer software.

Power Over Ethernet (PoE)

This device requires PoE to operate. It is compatible with all PoE sources.

Power over Ethernet is delivered in one of the following ways:

  • A network switch that provides PoE
  • A PoE injector device

Controlling Devices with Shure Designer Software

To control this device's settings, use Shure Designer software. Designer enables integrators and system planners to design audio coverage for installations using MXA microphones and other Shure networked devices.

To access your device in Designer:

  1. Download and install Designer on a computer connected to the same network as your device.
  2. Open Designer, and check that you’re connected to the correct network in Settings.
  3. Click Online devices. A list of online devices appears.
  4. To identify devices, click the product icon to flash the lights on a device. Select your device in the list and click Configure to control device settings.

Learn more at shure.com/designer.

You can also access basic device settings using Shure Web Device Discovery. Full control is available in Designer.

Using Designer's Optimize Workflow

Designer's Optimize workflow speeds up the process of connecting systems with at least 1 microphone and 1 audio processor. Optimize also creates mute control routes in locations with MXA network mute buttons. When you select Optimize in a location, Designer does the following:

  • Creates audio routes and mute control routes
  • Adjusts audio settings
  • Turns on mute synchronization
  • Enables LED logic control for applicable devices

The settings are optimized for your particular combination of devices. You can customize settings further, but the Optimize workflow gives you a good starting point.

After optimizing a location, you should check and adjust settings to fit your needs. These steps may include:

  • Deleting unnecessary routes.
  • Checking levels and adjusting gain.
  • Verifying that AEC reference signals are correctly routed.
  • Fine-tuning DSP blocks as needed.

Compatible devices:

  • MXA910
  • MXA710
  • MXA310
  • P300
  • IntelliMix Room
  • ANIUSB-MATRIX
  • MXN5-C
  • MXA Network Mute Button

To use the Optimize workflow:

  1. Place all relevant devices in a location.
  2. Select Optimize. Designer optimizes microphone and DSP settings for your equipment combination.

    If you remove or add devices, select Optimize again.

How to Update Firmware Using Designer (Version 4.2 and Newer)

Before setting up devices, check for firmware updates using Designer to take advantage of new features and improvements. You can also install firmware using Shure Update Utility for most products.

To update:

  1. Open Designer. If there's new firmware that you haven't downloaded yet, Designer shows a banner with the number of updates available. Click to download firmware.
  2. Go to Online devices and find your devices.
  3. Choose a firmware version for each device from the Available firmware column. Make sure that no one is editing device settings during an update.
  4. Select the checkbox next to each device you plan to update and click Update firmware. Devices may disappear from Online devices during an update. Don't close Designer while updating firmware.

Firmware Versioning

When updating firmware, update all hardware to the same firmware version to ensure consistent operation.

The firmware of all devices has the form of MAJOR.MINOR.PATCH (e.g., 1.2.14). At a minimum, all devices on the network, must have the same MAJOR and MINOR firmware version numbers (e.g., 1.2.x).

Light Ring

You can control the light ring's color, brightness, and status using Designer. Open the mute button's configuration window, and go to Settings > Lights to adjust the settings.

Mute Settings

To control mute settings, open the device's configuration window in Designer and go to Settings > Logic control.

  • Toggle: Press the button to toggle between muted and unmuted.
  • Push-to-talk: Press and hold the button to unmute the microphone.
  • Push-to-mute: Press and hold the button to mute the microphone.

Linking Mute Buttons to a Device

Use Designer to link one or more mute buttons to a device. When you link the mute button to Shure devices with IntelliMix DSP, the AEC stays converged to deliver the best performance.

In most rooms, all mute buttons control muting for the same device. To set this up:

  1. Create a location in Designer.
  2. Add the mute buttons and other Shure devices in the room to the location.
  3. Open the location and go to Routing.

    From here, you can link mute buttons to compatible devices.

  4. Drag and drop from each of the mute buttons to the device you want to mute.

    In rooms with at least 1 microphone and 1 audio processor, you can use the Optimize workflow to let Designer automatically create mute control routes for you.

    Use these guidelines to choose what device to the link the mute button to:

    Microphone with IntelliMix DSP (MXA910 or MXA710), no separate DSP: Link the mute buttons to the microphone.

    One or more microphones connected to separate DSP (P300, IntelliMix Room, or ANIUSB-MATRIX): Link the mute buttons to the DSP.

    Microphone connected to third-party DSP: If using the microphone's IntelliMix output, link the mute button to the microphone. If using the microphone's direct outputs, use third-party command strings to set up muting.

Compatible Devices

You can link the mute button to the following devices to control muting:

Using a Third-Party Control System

This device sends and receives logic commands over the network. Many parameters controlled through Designer can be controlled using a third-party control system, using the appropriate command string.
