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.

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.
Active electronics power the speaker
Ported enclosure design allows lower frequency extension down to 125 Hz octave band for sound masking and 115 Hz for paging and music

Plenum-rated, UL-listed, and complies with UL 2043
Delivers four uncorrelated audio channels to reduce phasing/comb-filtering
