Chapter 1: Getting Started Congratulations on purchasing your Beamforming Microphone Array. The Beamforming Microphone Array is a 24-microphone device with beamforming and adaptive steering technology designed specifically for use with the CONVERGE® Pro products: 880, 840T, 880T, 880TA. The Beamforming Microphone Array connects with the CONVERGE Pro through an Expansion Bus (E-bus) port: 3 arrays per supported CONVERGE Pro and up to 16 Beamforming Microphone Arrays can be daisy-chained in the site.
CONNECTIONS The following section illustrates the connections made in a sample Beamforming Microphone Array installation on a site. Powering the Beamforming Microphone Array Powering the Beamforming Microphone Array can be through a standard Power-over-Ethernet (PoE) switch or through an external PoE power supply. Use the appropriate AC cord to connect the PoE power supply to the AC power. Then plug the PoE cable into the LAN+DC connection on the power supply.
The Beamforming Microphone Array is connected to the CONVERGE Pro and to other Beamforming Microphone Array units via the E-bus in the same way as multiple CONVERGE Pro units are connected together. Each unit has a LINK IN and LINK OUT connection which allows the units to be “chained” together with the LINK OUT of one unit connecting to the LINK IN of the next unit. The steps in connecting the Beamforming Microphone Array are covered in the Beamforming Microphone Array Quick-Start Guide.
