General Description

®
The Microflex Advance™ Ceiling Array is a premium networked array 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 8 highly directional pickup lobes that capture participant audio
from overhead. Control the microphone with Shure Designer software, or a browser-based web application. The
microphone integrates seamlessly with Dante™ digital networked audio and third­party preset controllers, includ­
ing Crestron and AMX, to deliver a high-quality AV conferencing experience that appeals equally to integrators,
consultants, and meeting participants.

    Shure components shown in this diagram: Microflex Advance Microphones The MXA910 and MXA310 are equipped with Dante outputs, and connect directly to a network switch. Audio Network Interfaces The interfaces are used to connect analog devices such as loudspeakers and analog microphones to the network.
  • Page 5 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.
