ATC SCM105AC Pro Centre Channel Monitor
Reference 3 way active mid field loudspeaker for immersive and surround studios
The SCM105AC Pro is a purpose built centre channel monitor engineered for professional control rooms where accuracy, power and physical practicality matter equally. Designed by ATC Loudspeakers, it delivers the same uncompromising sonic performance found in ATC’s larger mid field systems, optimised in a lower height enclosure that integrates seamlessly beneath screens and consoles.
Based on the acclaimed SCM110A platform, the SCM105AC Pro is tailored specifically for centre channel duties in high end surround and immersive environments. It is an ideal match for ATC SCM50, SCM100 and SCM110A Pro monitors, making it perfectly suited to 5.1, 7.1 and Dolby Atmos music and post production rooms where tonal consistency and precise dialogue localisation are critical.
At its core is ATC’s proven three way active design with a symmetrical driver layout for controlled dispersion and stable imaging. Dual 9 inch Super Linear bass drivers provide authoritative low frequency extension with exceptionally low distortion, while the legendary 3 inch soft dome midrange reproduces dialogue, vocals and effects with remarkable clarity and realism. A 1 inch soft dome tweeter completes the system with smooth, extended high frequencies that remain accurate even at high playback levels.
Powering each driver is ATC’s proprietary Amp Pack, featuring precision active crossovers and discrete MOSFET Class A B amplification. This fully active approach ensures optimal driver control, wide dynamic range and consistent performance across long sessions, whether you are mixing feature films, broadcast content or immersive music projects.
The result is a centre channel monitor that delivers effortless output, outstanding transient response and absolute tonal accuracy, allowing critical decisions to translate reliably to any playback environment. For installations requiring alternative mounting solutions, an in wall version with remote amplification is also available under the SCM105AiWC Pro designation.
