Can I use more than one MXA910 ceiling array or MXA310 table arrays in a room? How do they connect together?
Yes. Just like any other microphone, you may install multiples to cover a room.
The audio output from multiple ceiling arrays (or table arrays) can be combined with a mixer or external DSP (i.e. SCM820, or QSC Qsys, or Biamp). Multiple arrays cannot directly share DSP resources with each other.
The microphones cannot be daisy-chained together, but by installing a small network switch with PoE under the table or in a ceiling, multiple array microphones can be locally connected and then a single cable run from the switch back to a central location.
Note that each microphone must be configured independently. At this time, the embedded software in the device does not allow for multiple devices to be configured from a single interface.
