Does the lead vocal sit right in your mix? Is there too much bass? Not enough? If your studio monitors are not telling you the truth, you’ve got problems. If you want to make great-sounding recordings that “translate” to the world outside your studio, accurate monitors are a must. Sweetwater’s advice: you can’t go wrong with the studio monitors trusted by George Massenburg, Chuck Ainlay, Nathaniel Kunkel, and many other world-renowned engineers: ATC. The ATC SCM45A Pro is an active 3-way with a 1″ dual-suspension Super Tweeter, a 3″ soft-dome midrange driver, and two 6.5″ short-coil carbon-paper cone bass drivers. The system is amplified by a custom, discrete MOSFET Class A/B tri-amp pack. 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.
