>The QSC AcousticCoverage Series AC-C4T is a ceiling mounted 4" full-range loudspeaker with 70/100V transformer, suitable for a wide variety of audio/video conferencing reinforcement, voice paging and background music applications.

AcousticCoverage Series is designed to offer integrators a cost effective solution for applications where voice reinforced coverage is of primary concern, while providing improved musicality often not seen in typical BGM class products.

A high quality 4 inch polypropylene cone transducer with butyl rubber surround offers pristine clarity through the critical vocal range for increased speech intelligibilty. With 140 degrees of conical coverage, the AC-C4T reduces the number of loudspeakers required for even coverage in low ceiling applications.

The easy to install blind mount assembly features a ported baffle which optimally tunes the galvanized steel backcan for added musicality, creating low frequency extension down to 70 Hz. To maintain this frequency response, the AC-C4T utilizes a variable tap 16 watt low saturation and low loss 70/100V transformer, accessible under the powder coated steel grill via a rotary selector which also includes an 8 ohm bypass setting.

To further enhance performance and speed of install with optimum result, advanced voicing filter sets using the Q-SYSTM Platform, including CXD Series amplifiers for a complete QSC systems solution.

Installers will appreciate the 4 pole Euroblock connector for loop thru wiring, located under a quick access swivel plate. Eliminating the termination hassles of star topology wiring designs, the generous Euroblock of the AC-C4T can accept four 18AWG pairs.

A safety tether tab is affixed to the adjustable conduit clasp plate for seismic sensitive installations. C-ring and tile rails are included with each pair packed assembly, complete with joining screws and cut-out template.

The AC-C4T baffle and grill are QSC standard white (RAL 9010) to match complimenting QSC product families and includes UV inhibitors to prevent discoloration over time. The AC-C4T may also be painted to match any décor.

To assist in successful systems integration, complete EASE, CAD, and BIM files are available for download online.
