IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers,
stoves, or other apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type
plug. A polarized plug has two blades with one wider than the other. A
grounding type plug has two blades and a third grounding prong. The
wide blade or the third prong are provided for your safety. If the provided
plug does not fit into your outlet, consult an electrician for replacement of
the obsolete outlet.
10. Only use attachments/accessories specified by the manufacturer.
11. Unplug the array during lightning storms or when unused for long periods
of time.
12. Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged, liquid
has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
13. Protect the PoE injector’s power cord from being walked on or pinched;
particularly at plugs, convenience receptacles, and the point where they
exit from the apparatus.

THE BMA CT
The BMA CT is a 2nd-generation Beamforming Microphone Array
solution for ceiling-tile installations, featuring 24 microphones, and
beamforming and adaptive-steering technology (think of it as smart
beam selection) designed specifically for the CONVERGE® Pro 2 (CP2)
products: 128, 128D, 128T, 128TD, 128V, 128VD, 128VT, 128VTD, 120,
48T, 48VT, 48VTD, and 48V. The arrays connect with the CONVERGE Pro
2 through a Peripheral Link (P-Link) port with either Regular (200 ft.) or
Long Distance (650 ft.) P-Link cables. Three arrays are supported per
CP2 via either regular or long-distance P-Link, and up to 6 arrays can be
daisy-chained in one regular P-Link chain with a stack of two CP2 mixers.
Power to the arrays is supplied through a Power-Over-Ethernet (PoE)
or P-Link connection from CP2. The array comes in both a 24-inch and
600mm size. There is also an adapter that converts the 600mm version
to 625mm.
IMPORTANT: The BMA CT arrays can be used only with CP2
systems. It is not compatible with CONVERGE Pro or first-
generation Beamforming Mic Array systems.
The most recent versions of firmware and software are available on the
ClearOne website at clearone.com/rl-search?combine=software.
QUICK-START OVERVIEW
Installing and using the BMA CT arrays in your CP2 site is subject to the
following parameters:
1. The arrays can only be used with CP2 systems.

2. You must have a 128, 128D, 128T, 128TD, 128V, 128VD, 128VT,
128VTD, 120, 48T, 48VT, 48VTD, and/or 48V. mixer in the site. The
arrays will not work with standalone 012, 128SR, or 128SRD units.
3. Connect up to 3 arrays (current) per CP2 unit, and up to 6 arrays
per Regular P-Link chain with 2 CP2 unit stack. More CP2 units may
be added to increase the number of arrays per site.
Quick-Start ProcedureS
These steps must be done in the following order to use the BMA CT in
your CONVERGE Pro 2 site:
1. Update the CONVERGE Pro 2 firmware to the latest version using
CONSOLE AI software.
2. Connect the array to the updated CONVERGE Pro 2 via the P-Link
bus.
3. Update the array firmware using CONSOLE AI. (The array firmware
cannot be upgraded without an updated CONVERGE Pro 2.)
4. Test the array.
5. Mount the array.

CONNECTING THE BMA CT UNITS
Connect the BMA CT units to the CP2 unit via P-Link connections using
CAT6-23AWG solid conductor RJ45 cables.
• You must power the BMA CT with an external IEEE 802.3at PoE+
source that provides 56V and 640 mA (36W).
• For a PoE+ power supply kit, ClearOne recommends ClearOne part
number 910-3200-202. When no speakers are connected to the BMA
CT’s, it can power up to three BMA CT devices.
• You can connect a PoE+ injector to a P-Link PoE port on a
CONVERGE Pro 2 (CP2), or connect it to the BMA CT’s PoE+ port.
• If you connect the PoE+ injector to the BMA CT’s PoE+ port, you
must also connect the CP2’s P-Link Out port to the BMA CT’s P-Link
In port.

• To use the PoE+ port on the BMA CT, slide the power-source
selection to PoE+. Otherwise, slide the switch to P-Link to receive
power over P-Link from a PoE injector connected to a different
device.

When a BMA CT drives speakers, it requires its own PoE injector. In this
case, be sure to set the power-source-selection switch to the left (PoE+
port).

UPDATING ARRAY FIRMWARE
1. Connect the P-Link cable between the CP2 units and the arrays.
2. Connect the CP2 units with CONSOLE AI.
3. Open the Firmware Loader screen.
4. Browse for the BMA_CT_vx.x.x.x.mdo file.
5. Download the array firmware.
6. The array(s) will default and reboot after the download of firmware.
7. Units are fully upgraded. (All array units connected via the P-Link on
the site are simultaneously updated.)
TESTING THE BMA CT UNITS
The BMA CT must be added to the site using the CONSOLE AI software.
This software also provides the capability of configuring the beams
(enable/disable) and other characteristics available in Configuration
mode. Refer to the online help available with the CONSOLE AI software.
VoLume & mute
These controls are available through the controller configured for your
CONVERGE Pro 2 site.
microPhone array Led indicatorS
The illuminated LED indicators on the face of the array change color
when the microphone array is active/muted. You can choose colors to
indicate either state, or even set the indicators to remain off by using
CONSOLE AI to change Unit Properties for the array.
