LAS VEGAS, NEVADA – SEPTEMBER 2014: TransAudio Group, U.S. rep for ATC and other boutique professional audio companies, introduces the ATC SCM20ASL Pro MkII near-field reference monitor. The ATC SCM20ASL Pro MkII improves upon the ATC SCM20ASL Pro. Like its predecessor, the MkII is a high-performance two-way active loudspeaker that is ideally suited for critical near-field applications or as surround channels in larger systems. Its exceptionally neutral output extends across the audible spectrum and is now improved by a new amplifier design, a new ATC-made dual suspension tweeter, and a new cabinet design.
"ATC is well-known for designing and building studio monitors that are unflinchingly truthful and that help engineers deliver mixes that translate everywhere," said Brad Lunde, president of TransAudio Group. "ATC founder Billy Woodman and his team of R&D engineers never tire in the pursuit of perfection, and improvements to the passive SCM20PSL Pro MkII led to parallel improvements in the active the SCM20ASL Pro MkII.”
The new SCM20ASL Pro MkII is based around the ATC 6.5-inch “Super Linear” LF driver with integrated midrange, utilizing the same SL technology developed for the larger nine-, twelve- and fifteen-inch based monitors. Constructed with a 75mm/three-inch voice coil and a short-coil, long-gap topology, it 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 high fidelity systems.
Five years in development, the new ATC dual-suspension 25mm tweeter offers lower distortion, higher output, and greater reliability. The electronics in the active design have also had considerable development time invested in them, resulting in reduced noise and distortion (a further -10dB @ 10kHz) and a reduced operating temperature for improved reliability. The amplifier design is a revised version of ATC’s discrete MOSFET Class A/B design with 200W and 50W continuous power available for the bass and high-frequency sections, respectively. The user controls have also been improved over the previous generation with more flexible input sensitivity controls and a revised low-frequency shelf control to help achieve good balance in difficult acoustic conditions. The amplifier includes protection circuits for both DC offset and thermal overload.
The new cabinet design maximizes linearity and minimizes size and weight. The cabinet has been restyled to more closely follow the larger monitors in ATC’s professional range and is constructed from heavily-braced MDF. Highly damped, elastomeric 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.
“Even given the excellence of the previous design, these new features lead to a substantive improvement,” Lunde concluded.
