ATC SCM45A Pro

Essential Information About the ATC SCM45A Pro 3-Way Active Studio Monitor

• High-performance 3-way monitoring for medium-sized control rooms, featuring MOSFET class A/B tri-amplification 150 W / 60 W / 25 W and factory calibration (frequency, gain, phase) for exemplary coherence.


• Handmade ATC transducers: 25 mm "S-Spec" double suspension tweeter, 75 mm soft dome midrange, 6.5-inch carbon paper cone woofer with short voice coil for minimal distortion and extended dynamics.


• Linear response (+/- 2 dB) from 70 Hz to 17 kHz, useful extension from 42 Hz to 25 kHz (-6 dB), controlled dispersion (+/- 80 deg H, +/- 10 deg V) and 112 dB continuous SPL at 1 m.


• Comprehensive rear panel: balanced XLR input (pin 2 +), sensitivity TRIM 0 to -6 dB (1 V to 2 V) and bass boost 0 to +3 dB at 40 Hz to adapt the speaker to the room.

At the Heart of the ATC Professional Range

Designed to fit between compact models and large main systems, the SCM45A Pro belongs to the SCM25/45/50/100/110/150 family. In this lineup, only the SCM25 and SCM45 models are exclusively active; they incorporate 3-way amplification with individually optimized frequency, gain, and phase correction in ATC's workshops. The SCM45A Pro builds on this expertise to offer a remarkably precise listening point in a medium-sized format.

For Critical Listening and Surround Configurations

Designed for nearfield and midfield monitoring, the SCM45A Pro excels in critical listening in all control rooms. It is also suitable as LCR surround monitoring for medium-sized control rooms, as well as for surround channels in medium to large studios where tonal coherence and dynamic headroom are priorities.
