ATC Loudspeaker Technology Launches The SCM16A Compact, Active Loudspeaker

October 3, 2007

Featuring newly developed driver technology and improved amplifiers, the SCM16A active loudspeaker is a robust monitor designed for the accurate reproduction of stereo and multi-channel audio in small and medium sized rooms. By virtue of its compact active (powered) design, the SCM16A could be utilised as the ultimate MP3 PA system! Enclosure Sharing a genuine professional heritage with ATC’s famous Active 20 Pro loudspeaker, the SCM16A’s solid, curved, cast-aluminium enclosure is exceptionally rigid and acoustically inert. The elegant lines of the die-cast aluminium cabinet are functional, as well as aesthetic. The compact 16+ litre design is finished in high loss silver-grey but can be custom coloured by special order to any shade required. Drivers The SCM16A features a neodymium 25mm soft dome tweeter. ATC’s new Constrained Layer Damping (CLD) technology has been utilised for the 150mm mid-bass driver (incorporating with a 45mm integral soft dome). This exclusive driver cone technology brings the advantages of high damping without unacceptable cone mass increase. With CLD, two lightweight cones sandwich a constrained damping layer. The structure is significantly more effective than free damping because, as the cone flexes, the damping material is forced into a shape that shears adjacent material sections. The alternating shear strain dissipates the unwanted vibration energy as low grade frictional heat. The results are reduced harmonic distortion between 300Hz - 3kHz and an extended frequency range with improved off-axis response. On-Board Amplification The SCM16A’s upgraded on-board amplifier pack provides 200watts to the mid/bass driver and 50watts to HF driver. Operating in Class A up to 2/3rds of output, this ultra-low distortion design is capable of continuous sound pressure levels greater than 108db. The electronic crossover offers an exceptionally smooth and even frequency response. Controls include bass level EQ and high frequency attenuation. Multi-channel Music and Cinema For multi-channel installations, the SCM16A replaces the T16 in ATC’s C4 multi-channel collection. Sitting between its acoustically-matched Active 10 and Active 20 range counterparts, the SCM16A can be mixed successfully with these models for flexibility multi-channel system design. The SCM16A is manufactured in-house and like all ATC products, it is backed by a 6-year warranty. Single units can be supplied for Multi Channel Installations.
