ATC (Acoustic Transducer Company) is a specialist manufacturer of loudspeaker drive units and complete sound reproduction systems, including the relevant electronic equipment. since it was formed in 1974, the British company has kept steadfastly to its founders aims of building loudspeakers and audio electronics, which employ the most effective of modern engineering principles. On that note ATC designs and manufactures loudspeaker drive units and systems to achieve levels of performance far in excess of the industry norm. This is achieved by adopting a thoroughly professional engineering approach to the issue of basic design, materials science and production technology. All ATC products are built to provide nothing less than the best sound reproduction money can buy and to meet the challenge of the latest digital recording technology.

Overview

2-Way Active Loudspeaker

The ATC SCM20A Pro mk2 is an active 2-way loudspeaker ideally suited to critical nearfield listening applications in all control rooms, LCR surround monitoring in small-to-medium control rooms, and surround channels in medium-to-large control rooms and provides faster editing with more consistent results on EQ'ing and balancing and less listening fatigue.

ATC’s 150mm/six-inch Super Linear bass/mid driver with a 75mm/three-inch voice coil and a short-coil, long-gap topology combines the high-power handling and low-power compression usually only found in large, high-efficiency systems with the fine resolution and balance of modern highfidelity systems. As a perfect complement the ATC SCM20A Pro mk2 features the ATC’s SH-25-76S 25mm/one-inch soft dome tweeter. With a massive neodymium motor, it provides an unparalleled linear and extended frequency response (-6dB @ 26kHz) and low non-linear distortion.

The amplifier is based on a discrete MOSFET Class A/B design with 200W and 50W continuous power available for the bass and high frequency sections, respectively and includes protection circuits for both DC offset and thermal overload. Controls for sensitivity and a low frequency shelf control help to achieve good balance in difficult acoustic conditions.

The cabinet is constructed from heavily-braced MDF. Highly damped, elastometric panels are bonded and stapled to the cabinet’s inner walls to suppress cabinet panel resonances, while the enclosure’s front panel is heavily radiused to reduce cabinet diffraction, improving the frequency response and imaging.
