SHURE MXA310B

The Shure MXA310B is the black Microflex Advance table array microphone for AV conferencing in boardrooms, huddle rooms and multi-purpose spaces. Steerable Coverage provides selectable polar patterns on four independent channels, with an additional automatic mixing channel, all delivered over Dante digital networked audio on a single PoE network cable.

Key Features

• Black finish MXA310 table array (series also available in white and aluminium)
• Independently adjustable polar patterns per channel: Cardioid, Hypercardioid, Supercardioid, Toroid, Omnidirectional, Bidirectional
• Toroid pattern for 360° coverage while rejecting sound from directly above (e.g. HVAC / projectors)
• 5 Dante transmit channels: 4 independent + 1 Automatic mixing
• Power over Ethernet (PoE), Class 0; maximum power consumption 4 W
• Browser-based HTML5 control application; Shure Designer software and Crestron/AMX control strings
• Configurable multi-coloured LED light ring for mute and coverage confirmation
