ATC SCM20A SL PRO MKII active monitors are a professional solution for studio applications where precision listening and reliability are required. Their compact design makes them perfect for near-field setups in both small and medium control rooms, as well as for use as surround channels in larger studios.

Proprietary ATC components for superior sound quality

ATC Mid/Bass and Super Tweeter Drivers.

Each unit features a 150mm Super Linear woofer with a 75mm voice coil, and a 25mm Soft Dome dual suspension tweeter, both developed in-house by ATC to ensure faithful and detailed sound reproduction.

Integrated Class A/B amplification

Internal amplifiers provide 200W power for low frequencies and 50W for high frequencies, using MOSFET discrete component circuits for maximum sound quality and reliability.

Designed for professional use in any environment

The SCM20A SL PRO MKIIs offer consistent dispersion and ±2dB amplitude linearity from 80Hz to 20kHz, making them ideal for a wide range of listening configurations. Overload protection with momentary gain reduction ensures stability even under heavy use.
