Amazingly Lifelike Nearfield Monitoring

You'll hear an amazing upgrade in the sound of your studio with the ATC SCM20ASL Pro mk2 active studio monitors. ATC monitors are handmade in the U.K. using cutting-edge components and processes, and you'll immediately hear why they're considered among the finest reference monitors in the world. You'll find ATC monitors in the studios of George Massenburg, Chuck Ainlay, Nathaniel Kunkel, and many other world-renowned engineers. For a nearfield monitoring experience that sets a new standard for sonic accuracy and mixing precision, choose the ATC SMC20ASL Pro mk2.

Proprietary speakers offer life-like playback

Great-sounding monitors start with great-sounding speakers. The ATC SCM20ASL Pro mk2 LF drivers are manufactured to exacting standards at their in-house facility. Hand-wound voice coils are made from flat oxygen-free copper wire and operate in a precision long magnetic gap. Specially designed magnet vents not only reduce air flow noise and heat, but increase power handling and reliability. These drivers are designed to give you a smooth and even frequency response without built-in EQ. In short, the SCM20ASL Pro mk2 monitor is designed to perform and sound at the top of its class.

A legacy of monitoring accuracy

A young engineer named Billy Woodman spent his formative years working side by side with some of the best speaker engineers of the day. In 1974, Woodman went on to found ATC (Acoustic Transducer Company). Since then, ATC has focused on one thing: creating the most accurate monitor loudspeakers possible. If you want to make great-sounding recordings that translate to the world outside your studio, accurate monitoring is a must. You need to hear every nuance of your audio, exactly as it was recorded and mixed. ATC monitoring equipment, expertly engineered with the highest-grade components, is designed to do provide just that. How good are ATC monitors? Just ask renowned producers and engineers like George Massenburg, Chuck Ainlay, Nathaniel Kunkel, and Doug Sax. You’ll also find ATC monitors in Abbey Road Studios, Sony Studios New York, Blackbird Studios Nashville, and many more world-class facilities. Sweetwater is proud to offer you ATC’s extensive range of professional studio monitors.
