Founded over four decades ago, QSC Audio Products, LLC, is a globally recognized leader in the design and manufacture of professional audio system solutions. Sound Associates have been specifying and installing QSC amplifiers for use in cinemas large and small for many years and now with Q-Sys we continue to deliver high quality cinema sound.

QSC introduced a full range of cinema speakers and Sound Associates is proud to have carried out all of the UK installations of their stage, sub-bass and surround speakers. The range now includes digital signal processing (DSP) and, again, Sound Associates have carried out numerous installations, both here in the UK as well as overseas.

In 2016 QCS acquired Ultra-Stereo Labs, Inc. (USL) allowing them to offer an industry-leading porfolio of sound processing solutions for the motion picture exhibition industry.


The SC-1120 extends QSC’s commitment to the cinema market by offering high-quality QSC sound for small room systems. As a member of the DCS Digital Cinema Series, the SC-1120 is a cost-effective screen channel loudspeaker for cinemas no longer than 35 feet (11 meters) from the screen to the last row of seating. The SC-1120 features a 12" (305 mm) woofer with 2.5" (63 mm) voice coil for exceptional low frequency bandwidth reproduction. The LF driver crosses over into a high frequency compression driver with 1.75" (44 mm) voice coil. Both drivers are combined in a single enclosure, simplifying installation.
