Microflex Complete Wireless
General Description
The Microflex Complete Wireless system offers full conference functionality with the added convenience of encrypted digital
wireless transmission for up to 125 conference units. It overcomes cable limitations at off-site meetings, in rooms with flexible
seating, or in historic buildings where drilling holes in furniture is impractical. Proven Shure RF interference detection and
avoidance technology delivers reliable transmission that protects against signal dropouts, and robust audio encryption keeps
meeting content private. Each wireless conference unit is powered by a smart lithiumion rechargeable battery whose remain
ing charge (in hours and minutes) can be checked remotely by a technician.
Features
RF Efficiency Sound quality is consistent with one speaker or several, and up to 125 units are supported
with just one access point transceiver and one RF channel.
Automatic Frequency Co
ordination
The system automatically scans the available spectrum and selects clean transmission
channels for best performance. Setting up the system is as easy as setting up a wireless
router.
Interference Avoidance While in use, the system automatically moves away from unexpected interference. Channel
adjustment protects against disruption to the audio.
Encryption Standard AES-128 encryption of audio and data keeps meeting content private.
Bi-Directional Wireless Provides return channels for interpretation audio to conference units and enables real-time
remote control of conference unit settings.

System Overview
The Shure Microflex Complete Wireless (MXCW) system provides a steady, reliable audio experience for off-site meetings,
flexible meeting rooms, or historic buildings. The system features automatic RF interference detection and avoidance,
rechargeable batteries for wireless conference units, encrypted digital wireless transmission, and digital audio networking using
Dante .
The MXCW access point has multiple mounting options for discreet communication between wireless conference units and the
digital audio network. The access point works within the 2.4 GHz and 5 GHz frequency bands to support up to 125 conference
units. Conference units have configurable roles for meeting participants, and can be routed to the floor audio or an interpreta
tion channel. The MXCW networked charging station charges and stores up to 10 Shure rechargeable batteries that can be
monitored through its own web application. Use the access point web application for system setup, and to monitor and control
conference units.
Getting Started
Set Up the System Access Point (MXCWAPT)
Connect the access point to a Power over Ethernet (PoE) source to turn on the device.
If prompted, select the operating region on the menu for RF coordination (some model variations).
Wait while the access point scans the area for the best available channel.
Once the channel is selected, the default wireless network (00) is ready for the MXCW microphones.

Access Point Transceiver (MXCWAPT)
The access point transceiver is the hub of the audio signal flow and manages the RF stability of each microphone in the group.
The access point performs the following functions:
Receives and decrypts wireless audio signals from microphones in the group
Delivers audio signal to the digital audio network
Hosts an embedded web server that provides access to the control software used to manage the system
Sends and receives control information (such as gain adjustment and link settings) between the components, control soft
ware and 3rd party controllers
Transmits an encrypted audio signal to the microphone's headphone output for listening to translated audio or other exter
nal sources.
