The E-P-B-4 and E-P-W-4 Cambridge Sound ManagementQt® Active Emitters are omni-directional direct field speakers provide a superior uniformity of sound with greater output levels than the passive emitters. This results in a clearer, better quality sound when used for paging and background music.

Power is delivered via an external power supply and power injectors, both available separately - see related products.

Emitters are installed in a simple grid pattern and daisy chained together using CAT-5 cable with RJ-45 connectors.

A ceiling tile mounting ring is included.
