ATC SCM45A Pro | Reference-Grade Monitoring Without Compromise

When precision matters most, whether you’re recording, mixing, or mastering, the ATC SCM45A Pro offers a level of clarity, control, and translation that few monitors can match. Designed and hand-built in the UK, this fully analog, three-way active studio monitor delivers deep, controlled low-end, pristine high-frequency detail, and unrivaled midrange definition, all without the need for DSP. If you’re looking for a near to midfield monitor that combines surgical accuracy with inspiring musicality, this is it.

Key Features of the ATC SCM45A Pro

  • Three-way active monitor with dual 6.5” low-frequency drivers

  • ATC’s first in-house designed SH25-76S dual-suspension tweeter

  • Exceptional midrange clarity with the ability to hear reverb tails, mic positions, and vocal textures in fine detail

  • Volume-independent performance to preserve mix decisions at any listening level

  • Phase-coherent imaging for accurate stereo and depth perception

  • Extremely high SPL handling, suitable for nearfield or midfield use, even full band tracking in the control room

Why the SCM45A Pro Stands Out

Engineers around the world trust ATC’s analog approach, and the SCM45A Pro shows why. With no DSP coloration, it pairs seamlessly with room correction solutions like Sonarworks, Trinnov, or Dirac Live. Instead of combining layers of DSP, you get natural, unprocessed signal reproduction, perfect for hybrid setups that demand both accuracy and flexibility. Whether you’re sculpting a 3D mix or presenting final masters to a client, these monitors deliver a soundstage that feels immersive, honest, and musical.

Built for the Long Haul

These are monitors you can grow with, not grow out of. The SCM45A Pro’s robust build and all-analog signal path make it a reliable studio reference for years to come. From intimate acoustic arrangements to high-impact electronic mixes, this is a tool that both inspires and informs. If you’re ready to hear your work in a whole new dimension, the 45s are ready to deliver.
