Feel the ultimate power of the ATC SCM50 SL Active Stand Mount Speakers - Designed and made in the U.K. 

• 3 x Class A/B MOSFET amplifiers, 200W bass, 100W mid & 50W high frequency
• User adjustable input sensitivity & bass shelf controls
• Balanced input & 2nd order Linkwitz-Riley active crossovers

The active SCM50ASL features an on-board 350W 3-way amp pack. Only a source and pre-amplifier (or combined source/pre-amp) are required to create a simple system capable of breathtaking performance.

The amplifier employed by the SCM50ASL is the result of years of R&D by ATC's engineering team and is precisely engineered and optimised to complement the SCM50ASL drive units. The system consists of a low-noise balanced input paired with a precision 3-way electronic crossover and three separate class A/B power amplifiers ― each dedicated to an individual drive unit.

Compared to an equivalent passive system, the active electronic crossover delivers superior timing and more precise level matching between drivers. The three dedicated power amplifiers deliver greater dynamic range and control, particularly at low-frequencies, bringing the listener a step closer to the original performance.
