Experience powerful, full-range sound masking, paging, and background music performance with the Cambridge E-P-W-25-4, a four-pack of white Qt Active Emitters with extended cable length for flexible installation across larger ceiling grids and open-plan spaces.

Key Features

• Deliver versatile audio performance – Qt Active Emitters provide higher SPL and a wider frequency range for masking, paging, and background music applications.
• Eliminate acoustic interference – four uncorrelated audio channels ensure smooth, consistent sound without phasing or comb-filtering.
