ATC SCM 20P SL Pro: very high performance passive 2-way studio monitor

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, anyone looking to seriously improve their reference nearfield monitoring experience surely owe it to themselves and their studio setup to take a listen to the SCM20PSL Pro in action? EQ, balance, and edit faster, with more consistent results and reduced listening fatigue using the latest reference nearfields from ATC.

ATC was founded on a principle of engineering excellence, and that principle still defines our products today. Given the right opportunities, ATC products will deliver exceptional audio performance, but the opportunities will only arise from careful and thoughtful installation and use.

The premise on which ATC began is a simple one – and one that, in many respects, is still true today: hi-fi loudspeakers tend to be detailed and accurate, but of limited dynamic range, while professional monitor speakers tend to express the opposite character.

ATC products were designed from the outset to offer the best of both. It’s an easy concept to describe, but surprisingly difficult to engineer. The difficulty inherent in designing such loudspeakers is one of scale. Hi-fi levels of accuracy and detail call for lightweight moving parts and delicate engineering. Professional monitor levels of performance, however, demand far more robust components engineered to survive the rigours of high level use for extended periods.

The only way to combine the two is through precision engineering of a class and scale more often associated with aerospace or motorsport. But the results are worth the effort and the cost. ATC loudspeakers, with their unique in-house designed drivers, combine the best of hi-fi and professional to devastating effect.

By selecting ATC, you join a group of music lovers, professional audio engineers, studios and musicians across the world that understand and value the engineering that goes into an ATC product - and the sound that comes out.
