Connect Speakers
A good time to connect external speakers is before you mount the BMA 360 in the ceiling.
With speaker wire (not included), connect external speakers to the Phoenix Euroblock connectors.
Mount the BMA 360
Mount Options
• Dropped (suspended) ceiling
• Hard ceiling, both recessed and surface
• VESA
This quick-start guide provides instructions to mount the BMA 360 to a dropped ceiling. Information for optional
mounting is available at ClearOne’s Resource Library.
Dropped Ceiling Mount
ClearOne recommends the use of 1/8 inch seismic cables (not included) as described here. To install the plenum shield,
complete steps 1 & 2. If you do not plan to install the shield, start at step 3.
1. Cut four 1-inch slots in the shield at the indicated locations.
2. Remove the liner from the adhesive in four places on the underside of
the shield, then thread the cables through the cut slots.
3. Attach the cables to the BMA 360 at four points as shown.
4. Lift the BMA 360 into place and attach the cables to structure.
