The QSC AcousticCoverage™ AC-S4T is a

surface mounted 4” two-way loudspeaker

with 70/100V transformer, suitable for a

wide variety of voice paging and background

music sound reinforcement applications.

AcousticCoverage™ 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 100 mm [4 in] polypropylene

cone transducer with butyl rubber surround

and a 25 mm [1 in] aluminium dome

tweeter offers pristine clarity through the

critical vocal range for increased speech

intelligibility. With 130 degrees of conical

coverage, the AC-S4T reduces the number

of loudspeakers required for even coverage

in close proximity.

The UV treated high impact ABS enclosure

and ported baffle assembly has been

optimally tuned for added musicality,

creating low frequency extension down to

70 Hz. To maintain this frequency response,

the AC-S4T utilizes a 16-watt low-saturation

and low-loss 70/100V transformer with

varying selectable taps, including an 8Ω

bypass.

To further enhance performance and speed

of install with optimum result, advanced

voicing via QSC Intrinsic Correction

™

techniques are obtainable using Q-Sys

™

networked audio processing platforms,

including CXD amplifiers for a complete QSC

systems solution.

Installers will appreciate the 4-pole

Euroblock connector for loop thru wiring,

located on the rear of the enclosure.

Eliminating the termination hassles of star

topology wiring designs, the generous

Euroblock of the AC-S4T can accept four

18AWG pairs.

The AC-S4T features brass inserts to accept

the included yoke mount and is secured

using the supplied thumb bolts. The grille is

adorned with a spring loaded and rotatable

logo for installation convenience in either

horizontal or vertical deployments.

The AC-S4T is available in white (RAL 9010)

or black (RAL 9011) to match

complimenting QSC product families . The

AC-S4T 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.
