MXA310 -- Table Array Microphone
Overview
General Description
®
The Microflex Advance™ table array is a premium networked tabletop microphone for AV conferencing environ­
ments, including boardrooms, huddle rooms, and multi-purpose spaces. Revolutionary technology from the Shure
DSP suite includes Steerable Coverage™, with selectable polar patterns on 4 independent channels to capture
participant audio. The innovative new toroid polar pattern delivers 360° coverage, while rejecting sound from di­
rectly above the microphone. Browser-based control software provides an intuitive user interface for microphone
attributes, including channel configuration, automatic mix settings, and preset templates. The microphone inte­
grates seamlessly with Dante™ digital networked audio and third­party preset controllers, including Crestron and
AMX, to deliver a high-quality AV conferencing experience that appeals equally to integrators, consultants, and
meeting participants.

  • Page 1 The Microflex Advance™ table array is a premium networked tabletop microphone for AV conferencing environ­ ments, including boardrooms, huddle rooms, and multi-purpose spaces. Revolutionary technology from the Shure DSP suite includes Steerable Coverage™, with selectable polar patterns on 4 independent channels to capture participant audio.

  • Page 2: System Overview

    ② Analog audio (microphone to network) Analog equipment, such as a wireless microphone system or a gooseneck microphone on a podium, connects to the Dante™ audio network through a Shure Network Interface (model ANI4IN) for a completely networked confer­ encing system.

  • Page 3: System Planning And Gear Requirements

    Analog microphones connect to the network through the Shure ANI4IN, while loudspeakers con­ nect through the Shure ANI4OUT.
  • Page 4 Expanded Control for Analog Devices Analog devices that are connected to the network through a Shure network interface (ANI4IN/ANI4OUT) benefit from additional remote control: Volume levels, equalization, and signal routing are managed through the web appli­ cation. For example, adjusting loudspeaker volume or muting a wired microphone, which would normally be done from the hardware, can now be controlled remotely over the network.
  • Page 5 Network Switch The network switch provides central connectivity for all networked components. Audio from any networked Shure microphones that are connected to the switch can be routed to any Dante-enabled device. The switch sends and receives audio and control data,...
  • Page 6 Shure ANI4IN Audio Network Interface (Analog-to-Dante Converter) The Shure ANI4IN Audio Network Interface converts 4 channels of analog audio into independent digital au­ dio channels on a Dante network. Adjustable gain and +48V phantom power deliver the flexibility to support line, auxiliary, and microphone­level devices.

    Automix Modes Classic Classic mode emulates the Shure SCM820 automixer (in its default settings). It is renowned for fast­acting, seam­ less channel gating and consistent perceived ambient sound levels. Off-attenuation in this mode is fixed at -12 dB per channel, regardless of the number of open channels.
