ATC Debuts New SCM45A Pro

ATC has launched the SCM45A Pro, an all-new high-performance, three-way compact active loudspeaker, which debuted at the NAMM Show 2015.

Aston Down, Gloucs., UK (March 6, 2015)—ATC has launched the SCM45A Pro, an all-new high-performance, three-way compact active loudspeaker, which debuted at the NAMM Show 2015.

The SCM45A Pro is a completely new design, yet shares many features with its smaller sibling, the SCM25A Pro three-way, compact active loudspeaker. As a mid-size, three-way design that can be used in near- or mid-field positions, the SCM45A Pro fills a gap in ATC’s studio monitoring loudspeaker range.

In contrast to the SCM25A Pro, the SCM45A Pro features a second woofer for deeper bass response and increased SPL, as well as ATC’s new proprietary dual-suspension tweeter—the first to be designed and built by the company, and the result of six years of research and development by ATC managing director Billy Woodman and R&D engineer Richard Newman—for increased resolution in the top end.

“The SCM45A Pro is especially exciting since not only is it a completely new addition to the range, but it’s also the first ATC three-way professional monitor to incorporate our new high-performance SH25-76S dual-suspension tweeter,” says Newman. “The SCM45A Pro also incorporates a new variant of our existing SB50-164 short-coil bass driver, which we designed and engineered specifically to operate in a parallel wired pair. Given that the efficiency of our three-way models is essentially set by the bass driver, the larger combined radiating area of the two 6.5-inch bass drivers increases system efficiency, putting less demand on each individual bass driver and reducing drive unit excursion for a given SPL and low frequency response. This results in further reduced non-linear distortions in the bass drivers’ 20 Hz to 380 Hz operating band.”

The units are powered by ATC’s proprietary active tri-amp pack, a three-channel discrete MOSFET class A/B design with 150W, 60W, and 25W for the bass, mid and high frequency ranges, respectively.
