ATC - Home in the Pro Studio
Grammy-winning mix engineer Tom Elmhirst augments ATC monitoring setup at ‘home’ in Electric Lady Studios, NYC.
On mixing Skyfall by Adele - “The accuracy of the SCM50ASL Pros proved invaluable for mixing such a complex song with so much orchestration.”
ATC SCM50 SL
Passive Loudspeaker
The monitors’ ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics lies mainly in the SM75-150S soft dome midrange driver.

The SCM50 ASL (active) and SCM50 SL (passive) are designed to perform at their best in the recording studio or at home with the finest quality hi-fi equipment.
The monitors’ ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics lies mainly in the SM75-150S soft dome midrange driver. However, recent modifications that include the new ATC SH25-76S tweeter and enhanced port profile have brought about further improvements to all performance parameters.
Each drive unit in the active model has its own dedicated and individually matched MOS-FET amplifier, while the 234mm/9″ bass driver incorporates ATC’s unique Super Linear Magnet technology. Our active crossover network consists of a wide band-width, electronically balanced input stage with high common mode rejection and very low distortion.
Like the HF, mid and bass drivers, all electronics are designed and manufactured in-house to create a no-compromise active system. In passive form, the SCM50 SL provides broad and symmetrical dispersion, excellent amplitude and phase characteristics throughout the frequency range.
Speakers are supplied with stands and fabric wrapped grills.

The ATC Factory Tour
We were invited to visit the ATC Loudspeaker factory for a tour. We decided to use this exclusive opportunity to film the tour, and share the experience with you
Follow the production of a speaker from the initial stages all the way to its final testing, led by Ben Lilly and Richard Newman.
“….striving to make loudspeakers as near perfection in their performance as it is possible to make them.”
