The ATC SCM300ASL Pro is a large format main studio monitor designed for critical professional monitoring in high level control room environments. Built around ATC’s proven active loudspeaker philosophy, the ATC SCM300ASL Pro combines extremely high output capability with exceptional accuracy, dynamic control, and long term reliability. This system is intended for use as a main monitor in recording, mixing, and mastering facilities where absolute confidence in translation and performance is essential.
At the heart of the ATC SCM300ASL Pro is a three way active loudspeaker system featuring ATC’s 34mm soft dome high frequency driver, the renowned 75mm Super Dome midrange driver, and twin 375mm SL specification low frequency drivers. This driver combination delivers wide bandwidth performance with controlled dispersion and outstanding amplitude linearity, ensuring consistent tonal balance and imaging across the listening area.
The Super Dome mid driver provides exceptional clarity and low distortion through the most critical part of the audio spectrum, while the dual SL bass drivers deliver deep, powerful, and controlled low frequency reproduction suitable for both free standing and soffit mounted installations.
The system is powered by ATC’s P4 rack mount grounded source amplifier, delivering a total output of 850 watts via a class A/B design. Amplification is optimised for each driver, with separate power stages for bass, mid, and high frequency sections. The P4 amplifier incorporates even order critically damped filters and comprehensive protection systems, including active FET momentary gain reduction and thermal protection for the high frequency driver. This ensures consistent performance and long term operational stability under demanding studio conditions.
Designed for flexibility, the ATC SCM300ASL Pro supports both free standing and soffit mounted configurations, with extended low frequency performance available when soffit mounted. With coherent horizontal and vertical dispersion characteristics and a maximum continuous sound pressure level of 121dB at one metre, the ATC SCM300ASL Pro delivers authoritative monitoring with precise imaging and control. The system is backed by a six year warranty, reflecting ATC’s commitment to engineering quality and long term durability.
