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. The power for the Beamforming Microphone Array is supplied through a Power-Over-Ethernet (PoE) connection.

The Beamforming Microphone Array supports use in ceiling-mounted and wall mounted modes, leaving the conference room table area free of clutter, as well as a standard table-top mode.

» IMPORTANT: The Beamforming Microphone Array only can be used with CONVERGE

Pro systems operating at version 4.X software and firmware.

Instructions for updating CONVERGE Pro firmware and Beamforming Microphone Array firmware are included in the Beamforming Microphone Array Quick-Start Guide which is found on the ClearOne website at:

http://www.clearone.com/resources#professional_microphones

This guide covers the steps followed to mount the Beamforming Microphone Array in either a solid or drop-ceiling. This guide can also be downloaded from the ClearOne website at:

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. Route the PoE cable where it can be fed through the ceiling mount assembly, wall mount or to the conference table with the Beamforming Microphone Array. The following illustration shows the cable connections with the PoE Power Supply.

Power Cord to AC Power

PoE Ethernet Cable to Beamforming Microphone Array

» NOTE: The PoE connection is only for power, not control. Power must be supplied to

individual units; no daisy-chain power is allowed.

e-Bus connections

The Beamforming Microphone Array units are connected to the CONVERGE Pro stack via the LINK IN and LINK OUT E-bus connections using CAT5E RJ45 cables.

» NOTE: Firmware upgrades and Beamforming Microphone Array operation are

performed via the E-bus connection. Plugging the PoE cable into the E-bus connections may cause damage to the Beamforming Microphone Array.

» NOTE: One or two E-bus connections are required depending on where in the stack

the Beamforming Microphone Array is placed. Only one E-bus,cable, LINK IN, is required if the array is the end of the stack; two are needed if the stack continues to another array or CONVERGE Pro unit (LINK IN and LINK OUT).

Chapter 1: Getting Started 2

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. Instructions for configuring the Beamforming Microphone Array are included in the CONVERGE Console version 4.X online help.

DROP CEILING CUT-OUT

If ceiling tile is 2’ x 4’, then this dimension must be oriented with the 2’ side.

Orientation does not matter with a 2’ x 2’ tile as long as it is square.

Use the screws to fasten the Ceiling Mounting Plate to the top of the Suspension Column. Place

Use #1 Phillips screwdriver bit

the plate on the Suspension Column so that the screw heads recess into the hole counter sinks. (Ignore the short studs on the plate. These are for wall-mount usage.)

» NOTE: Be certain you have the correct Suspension Column for your installation as

determined by your ceiling height. There are SKU’s for kits containing either a 12-inch or 24-inch Spanner Post (910-001-005-12 or 910-001-005-24).

to avoid damaging screws.

Ceiling Mounting Plate

Suspension Column

» NOTE: The Ceiling Mounting Plate must be attached to safeguard against an

accidentally unsecured Suspension Column with the Beamforming Microphone Array attached sliding down and out of the ceiling.

Feed the Suspension Column, with the Ceiling Mounting plate attached, through the top of the cutout ceiling tile. This must be done before adding the Trim Plate and the Mic Mounting Plate to the bottom of the Suspension Column.
