概述

General Description

The Microflex Advance Ceiling Array is a premium networked array microphone for AV conferencing environments, including

boardrooms, huddle rooms, and multi-purpose spaces. The ceiling array uses Shure's Steerable Coverage with Autofocus

technology: 8 highly directional pickup lobes capture participant audio from overhead, continually fine-tuning the position of

each lobe in real time as participants lean back in their chairs or stand up .

The microphone also includes the IntelliMix DSP suite, which includes AEC, noise reduction, automatic mixing, and more.

Control the microphone with Shure Designer software, or a browser-based web application. The microphone integrates

Steerable Coverage delivers precise pickup for up to 8 independent lobes

Automatic lobe positioning speeds up installation

Patent-pending Autofocus technology continually fine-tunes the position of each lobe in real time, for consistent sound

Available on firmware 4.x and newer through a free update

IntelliMix DSP provides automatic mixing, AEC, noise reduction, automatic gain control, delay, compressor, and channel

Available on firmware 4.x and newer through a free update

Shure Designer system configuration software provides comprehensive microphone and pattern control

With Designer, you can also design coverage with online and offline devices, and route audio between Shure devices

If Designer isn't available, use the browser-based web application to control the microphone

Compatible with Shure SystemOn audio asset management software for remote monitoring and real-time alerts about

critical issues

Network Connectivity

Discrete audio channels for each lobe and an automix channel are delivered over a single network cable

Dante digital audio coexists safely on the same network as IT and control data, or can be configured to use a dedicated

network

Control strings available for third-party preset controllers including Crestron and AMX

Professional Design

Sleek industrial design blends with contemporary board rooms and meeting spaces

Available in white, black, and aluminum finishes (detachable grille can be custom painted)

支持 Dante 的扬声器和放大器直接连接到网络交换机。模拟扬声器和放大器通过 Shure 网络接口（ANI4OUT 型号）连接到

网路交换机，该网络接口可以将 Dante 音频通道转换为模拟信号，并通过 4 个独立的 XLR 或块状接头输出传输这些模拟信

号。

音频：通过 Dante Controller 或 Shure Designer 软件路由音频。Dante Virtual Soundcard 支持直接在计算机上进行音频监

听和录制。

Differences Between 3.x and 4.x Firmware

When you update an MXA910 from 3.x to 4.x firmware, you'll be able to use IntelliMix DSP features optimized for MXA.

Here's what changes with 4.x firmware:

You can now use AGC, AEC, noise reduction, compressor, and delay.

These DSP features don’t affect individual channel outputs—they only apply to the Automix Out channel

If you’re currently using the Automix Out channel on a 3.x device and you update it to 4.x, the following settings will be

AGC: enabled

AEC: enabled

Lobes move automatically for consistent sound when participants lean back in their chairs or stand up.

The microphone now has AEC, so there's no need for echo reduction.

The Echo Reduction Reference In channel's name in Dante Controller is now the "AEC Reference In" channel. Any

Template 1's lobe positions have changed.

If you're using Template 1 with the default lobe positions, updating to 4.x will change your lobe positions.

After updating, all custom lobe positions and Dante routes will stay the same.

波瓣朝向每一位发言者正面。视频会议时，发言者可能会面对屏幕，所以要仔细考虑话筒的布置。

避免直接将话筒布置在不需要的声源附近，比如通风口或噪杂的投影机处。

如果房间内回音太大，应考虑安装噪音消减设备，以提高语音清晰度。

天花板矩阵话筒的拾音模式比短枪式话筒的更为狭窄，因此与其它话筒相比，可以布置的更远离声源。尽管 Web 应用程序

显示了每个通道理想的覆盖区域，但仍需牢记，在音频降解和断开之间并没有特定的界限。在产品规格中可查到每个设定宽

度的波瓣灵敏度数据。

和所有话筒一样，音调随着与声源的距离的增大而改变。

清晰度尺度可帮助预先了解话筒在给定高度下的效能。

在较远的距离上，波瓣的覆盖区域会扩大。
