ATC’s flagship active main monitors
The ATC SCM300ASL Pro are ATC’s largest 3-way active main monitors, for the biggest control rooms, scoring stages and mastering studios. Twin 15″ Super Linear woofers, the 75 mm soft-dome midrange and the external 850 W P4 amplifier deliver enormous dynamic range and bass down to 20 Hz when soffit-mounted, with the neutrality expected from ATC.
Twin 15″ woofers and 121 dB
With twin 375 mm Super Linear woofers, the SCM300ASL Pro reach 121 dB continuous SPL and extend to 25 Hz free-standing, or 20 Hz when flush-mounted in the wall. They are the choice for large control rooms that need full-range playback without compromise.
Accuracy at every level
ATC’s 75 mm soft-dome midrange and active crossovers keep the mids and imaging clean, whether you are working quietly or playing loud for a client. That is why large ATCs are found in studios such as British Grove, Blackbird and EastWest.
P4 amplifier and 6-year warranty
The external 5U P4 amplifier gives every driver its own class A/B channel, with active protection and thermal tweeter protection. Everything is hand-built by ATC in England and covered by a 6-year warranty.
