Microflex Complete Wireless
General Description
The Shure Microflex Complete Wireless (MXCW) system is a conferencing solution that provides a steady, reliable audio ex
perience for up to 125 conference units. MXCW overcomes cable limitations for off-site meetings, flexible meeting rooms, or
historic buildings where drilling holes in furniture is impractical. The system features automatic RF interference detection and
avoidance technology, 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, and works within the 2.4 GHz and 5 GHz frequency bands. Use the access point web application for sys
tem setup, and to monitor and control conference units. Conference units have configurable roles for meeting participants, and
can be routed to the floor audio or an interpretation channel. Each wireless conference unit is powered by a smart lithium-ion
rechargeable battery whose remaining charge can be checked remotely by a technician. The MXCW networked charging sta
tion charges and stores up to 10 Shure rechargeable batteries that can be monitored through its own web application.
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.

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 and receives digital and analog audio signals via Dante and XLR
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.
