1 Beamforming Microphone Array 2
Chapter 1: Getting Started
Congratulations on purchasing your Beamforming Microphone Array 2 (BFM2). The BFM2 is a 2nd
generation Beamforming Microphone Array product featuring 24 microphones, and beamforming
and adaptive steering technology designed specifically for the CONVERGE® Pro 2 products: 128,
128D, 128T, 128TD, 128V, 128VD, 120, and 48T.
»IMPORTANT: The BFM2 only can be used with CONVERGE Pro 2 systems. It is not
compatible with first generation CONVERGE Pro or Beamforming Microphone Array
systems.
CONNECTIONS
This section explains the connections in BFM2 installations.
powering aBeamforming microphone array 2
Powering a BFM2 can be...
• from a CONVERGE Pro 2 via a Peripheral-Link (P-Link1), with a single cable carrying power,
audio and control
• via a Power-Over-Ethernet (PoE) power supply/Injector2, third-party or ClearOne provided (a
ClearOne PoE Injector can power up to three BFM2 units)
• via a standard PoE Ethernet Switch3
poe connection
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. Route the PoE cable where it can be fed
through a mount assembly or to the conference table with the BFM2. Figure 1 illustrates PoE Power
Supply cable connections.
Figure 1
»NOTE: The PoE connection is only for power, not control. If not using a ClearOne
PoE Injector or similar specification standard PoE Injector, power must be supplied
to individual units.

Up to three BFM2 arrays are supported per CONVERGE Pro 2 unit, as seen below in Figure 3.
Up to 6 P-Link devices can be daisy-chained in a single P-Link chain.

p-link connections
BFM2 units are connected to CONVERGE Pro 2 units and to other BFM2 units via the P-Link. Each
BFM2 unit has a P-Link In and P-Link Out connection that allows units to be “chained” together with
the P-Link Out of one unit connecting to the P-Link In of the next unit.
»NOTE: One or two P-Link connections are required depending on where in the stack
a BFM2 is placed. Only a P-Link In cable is required if the array is at the end of a
stack; both a P-Link In and P-Link Out cable are needed if the stack continues to
another array or CONVERGE Pro 2 unit.

Instructions for connecting the BFM2 are in the Beamforming Microphone Array 2 Quick-Start
Guide, and in the CONVERGE Pro 2 CONSOLE online help for configuring the BFM2.
»NOTE: Firmware upgrades and BFM2 operation are performed via the P-Link
connection. Plugging the PoE cable into the P-Link connections may cause damage
to the BFM2.
Make sure CONVERGE Pro 2 firmware is updated. Instructions for updating CONVERGE Pro 2
firmware can be found at:
