Shure MXCW640 Wireless Conference Unit
Shure MXCW640 Wireless Conference Unit
The MXCW640 Wireless Conference Unit brings wireless convenience to discussions and conferences. The unit can be configured for Chairman, Delegate, Listener, or Ambient Microphone operation and supports multiple microphone activation modes to suit different meeting styles.
The 4.3-inch color touchscreen provides easy access to meeting information, including the speaker list, voting, and interpretation channel selection. The 10-pin modular connection accommodates MXC-series gooseneck microphones and can be locked for added security. The built-in loudspeaker provides high intelligibility and remains on even when the microphone is active.
Speak and mute/function buttons provide positive feedback when pressed and include LED status indicators. An NFC ID card slot allows identification of meeting participants. Dual 3.5mm headphone jacks with individual volume controls provide comfortable listening to interpretation channels or floor audio through headphones or earphones.
The MXCW640 operates for over 11 hours on a fully charged battery. The SB930 rechargeable Li-Ion battery (included) slides into the rear of the conference unit and is removable for charging in the MXCWNCS networked charging station. A micro-USB port allows the battery to be charged while installed, while the conference unit is operating.
