Cambridge Sound Management and Biamp
Cambridge Sound Management is now part of Biamp, and its direct-field masking platform is what we specify on almost every project. It is simple to install, easy to zone and easy to adjust as buildings change.
Direct-field, not plenum
Older systems fire loudspeakers upwards into the ceiling void and rely on sound filtering back down, which makes coverage uneven and hard to predict. Direct-field emitters face down into the occupied space, so the sound arriving at desk level is consistent, and far less power and cabling is needed to get there.
- Small emitters mounted in the ceiling tile, plasterboard or on exposed structure
- Even, predictable coverage that measures the same across the floor
- Simple low-voltage cabling in a daisy-chained loop
- Works with tile grids, open ceilings and hard-lid construction


Zoned control
Independent zones let a boardroom, an open floor and a reception each sit at their own level and schedule.
Networked configuration
Systems can be configured and adjusted over the network, so level changes after a churn don't need a ladder in every room.
Paging and music on the same network
Announcements and background music can share the emitter network, zoned so they only play where they should.
Scales from one room upwards
The same platform covers a single private office or a whole campus, so later phases match the first.

Product selection is part of the design
Which controller, emitter and mounting kit suits your building depends on ceiling construction, zone count and whether paging or music is in scope. We confirm the exact specification after the survey rather than quoting a generic kit list.
