The Shure A400MB mute button accessory is compatible with the MX395-LED and MX400SMP, with a low profile design ideal for surface mounting to boardroom tables. The switch adds a programmable button for microphone LEDs and local or remote mute control with Shure products or third-party control systems.
① Color Ring
Place around drilled hole to match microphone color.
② Mute button
Touch to mute microphone.
③ Mute button cable
Connect to the plug-on adapter.
④ Spacer
Use the spacer to adjust to different table thicknesses. Pull the mute button cable through the gap.
*⑤ Wingnut
Use to tighten the mute button under the table. Included with MX395 and MX400SMP only.
⑥ Plug-on adapter
Sits underneath the table surface, provides power, and controls signals to the mute button.
The mute button fits in tables that are between 15 to 30 mm (.59 to 1.18 inches) thick.
Note: Remove the protective blue film from the top of the mute button.
The mute button requires a 48 V phantom power source.
Use the included 6-pin block connector to wire the microphone to a DSP or other logic-enabled device, such as the ANI22-BLOCK or ANI4IN-BLOCK.
6-pin block connector
Note: The block connector screw terminals face downwards so they are accessible from under the table after installation.
Disconnect the adapter from the A400MB and any logic devices before disassembly. Remove the 2 Phillips head P1 size screws from the base of the adapter.
Use the DIP switches to configure logic settings and mute button behavior. DIP switches are down by default, and settings can only be changed when the device is powered off. Changes take effect when the mute button is powered back on.
DOWN (default) | UP | |
---|---|---|
1 | Toggle | Momentary |
2 | Push-to-Mute | Push-to-Talk |
3 | Local Mute | Logic Control |
4 | Green LED = talk, Red LED = mute | Red LED = talk, Green LED = mute |
5 and 6 work together to make 4 touch sensitivity settings: 1 (lowest) - 4 (highest) | 5 UP, 6 DOWN = 1 | |
5 DOWN, 6 DOWN = 2 (default) | ||
5 DOWN, 6 UP = 3 | ||
5 UP, 6 UP = 4 |
Note: Higher sensitivity settings are more likely to cause accidental touch responses.
Use these settings if connecting the microphone to a logic-enabled device, such as the ANI4IN-BLOCK or ANI22-BLOCK:
*Note: The A400MB connector plugs in upside down relative to the ANI connector. The cable should be wired in a 1:1 pin-out configuration when both connectors face the same direction.
① MX395-LED:
Runs the audio signals and features logic connections to receive logic mute and LED control signals.
② A400MB:
Adds programmable button for microphone LEDs and mute control, and connects to analog input.
③ ANI22IN-BLOCK:
Connects microphones to the audio network and converts analog to Dante.
④ Network Switch:
Provides Power over Ethernet (PoE) to the ANI22 and P300, while also supporting all other Dante-enabled audio equipment.
⑤ P300:
Provides IntelliMix processing for videoconferencing software.
⑥ Computer:
Connects to P300 USB to provide mute synchronization with videoconferencing software, such as Microsoft Teams or Zoom.
