General Description The MXW APXD2 is an all-in-one wireless microphone system that combines a 2-channel wireless transceiver, digital audio processing and two charging bays into a convenient tabletop device. On­board Dante, analog, USB and Bluetooth audio con­ nections enable local sound reinforcement and video conferencing applications in either standalone or networked installations. The front panel includes at-a-glance indicators and touch-sensitive buttons to facilitate quick out-of-the-box setup and intuitive system use, without the need for additional screen-based user interfaces. In networked installations, a computer can remotely control and monitor connected units via the built-in network interface. Features Standalone and networked installations Front panel user interface for simple setup and intuitive use Audio I/O: analog, Dante, USB, Bluetooth Built-in audio DSP: Automixer, Echo Cancellation, Noise Reduction Dual RJ45 to separate audio and control traffic (3 modes) Two built-in charging bays for wireless microphones Microphone Transmitters MXW+ microphones transmit an encrypted, wireless audio signal to the access point. Three form factors are available: Hybrid Bodypack (MXW1X) The bodypack secures to a belt or strap for hands­free, mobile communication. It features a TQG input for lavalier connec­ tion and an integrated omnidirectional microphone. Handheld (MXW2X) The handheld enables presenters to communicate using legendary Shure SM58, SM86, BETA58 and VP68 microphone cartridges. Boundary (MXW6X/C, MXW6X/O, MXW6XW/C, MXW6XW/O) Shure Incorporated The boundary transmitter sits on a table or desk to transmit speech while discreetly blending into any conference environ­ ment. Callouts ①Mute/Active Button Changes the audio status from Active to Mute, or Mute to Active.
