Active Monitors

The ATC SCM100ASL Pro are 3-way active monitors for medium to large control rooms, mixing and mastering studios. They combine a 12″ Super Linear woofer, ATC’s 75 mm soft-dome midrange and a built-in 350 W three-channel amplifier, for high SPL, full bass and the clean, neutral performance of the larger ATCs.

The ATC SCM110ASL Pro are 3-way active monitors with twin 9″ Super Linear woofers, ATC’s 75 mm soft-dome midrange and a built-in 350 W amplifier. They keep the well-known balance of the SCM50ASL Pro with more and deeper bass, which is why mixing and mastering studios around the world choose them.

The ATC SCS70iW Pro is the flush-mount version of the SCS70 Pro, designed for soffit installation alongside ATC in-wall monitors in stereo and immersive systems such as Dolby Atmos. The amplifier sits in a separate R1-300 unit, keeping the wall cabinet shallower.12″ long-throw wooferIt uses the same hand-built 300 mm SS75-314SC woofer as the SCS70 Pro, reaching down to 22 Hz with 110 dB continuous / 116 dB peak SPL, with the same acoustic performance as the free-standing version.R1-300 remote amplifierThe single-channel 300 W MOSFET class A/B R1-300 amplifier, a 7U unit for rack or wall mounting, connects to the subwoofer via NL4 speaker cable and a 5-pin XLR indicator cable (sold separately, priced by length).Full controlStereo balanced inputs and link outputs, level, low-pass and phase controls, and footswitch muting (footswitch sold separately). Hand-built in England with a 6-year warranty.

The ATC SCS70 Pro is a 12″ active subwoofer for professional monitoring in stereo, surround and immersive formats such as Dolby Atmos. It is designed to partner the ATC active monitor range.12″ long-throw wooferThe hand-built 300 mm SS75-314SC woofer reaches down to 22 Hz (-6 dB) with 110 dB continuous / 116 dB peak SPL, staying controlled with low distortion at high levels.300 W MOSFET amplifierThe built-in MOSFET class A/B amplifier delivers 300 W into 8 Ω with THD+N below 0.003% and is convection cooled for silent operation in the control room.Easy system integrationStereo balanced XLR inputs and link outputs, a 50/65/80/320 Hz low-pass filter, level, phase and polarity controls, and footswitch muting (sold separately). Hand-built in England with a 6-year warranty.

The ATC SCM200ASL Pro are large-format 3-way active main monitors for large control rooms, mixing and mastering studios. With twin 12″ Super Linear woofers, ATC’s 75 mm soft-dome midrange and an external 850 W P4 amplifier, they deliver high SPL, deep bass and the neutral, detailed performance that made ATC a reference in professional studios.

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.

The ATC SCM50AC Pro is the centre-channel version of the SCM50ASL Pro, for 5.1, 7.1 and immersive (Dolby Atmos) systems. It uses the same drivers and the same built-in 350 W three-channel amplification, so the centre channel matches the left and right SCM50ASL Pro perfectly in tone and dynamics.

The ATC SCM100AC Pro is the centre-channel version of the SCM100ASL Pro, for 5.1, 7.1 and immersive (Dolby Atmos) systems. It uses the same drivers and the same built-in 350 W three-channel amplification, so the centre channel matches the left and right SCM100ASL Pro perfectly in tone and dynamics.

The ATC SCM150AC Pro is the centre-channel version of the SCM150ASL Pro, for 5.1, 7.1 and immersive (Dolby Atmos) systems. It uses the same drivers and the same built-in 350 W three-channel amplification, so the centre channel matches the left and right SCM150ASL Pro perfectly in tone and dynamics.

The ATC SCM105AC Pro is a 3-way active centre-channel monitor, designed from the ground up for the centre position, with a low-height cabinet that fits easily into crowded control rooms. It is based on the SCM110A Pro and partners the SCM50, SCM100 and SCM110A Pro in 5.1, 7.1 and Dolby Atmos systems.

The ATC SCM45A Pro are mid-size active 3-way monitors in a horizontal cabinet. They are designed for critical near-field monitoring in any control room, LCR monitoring in medium rooms and surround channels in medium to large rooms.Twin 6.5″ woofersBass comes from two hand-built 164 mm short-coil woofers with carbon-paper cones. Response extends to 42 Hz (-6 dB) with up to 112 dB continuous SPL, from a cabinet that fits on the console.75 mm midrange dome and «S-Spec» tweeterThe ATC 75 mm soft-dome midrange sits at the centre of the cabinet with the 25 mm dual-suspension «S-Spec» tweeter. The symmetrical layout gives consistent ±80° horizontal dispersion and a clear centre image.MOSFET class A/B tri-ampThe built-in amplifier delivers 150 W to the bass, 60 W to the mid and 25 W to the high section. 4th-order filters at 380 Hz and 3.5 kHz include phase compensation. Rear-panel controls adjust input sensitivity (0 to -6 dB) and bass boost (0 to +3 dB at 40 Hz).

The ATC SCM20A Pro MkII (SCM20ASL Pro) are compact active 2-way studio monitors for critical near-field monitoring in any control room, as well as LCR or surround duty in small to large rooms. They combine ATC drive units, hand-built in England, with 250 W of built-in amplification per speaker.6.5″ Super Linear wooferThe 150 mm SB75-150SL woofer uses a 75 mm voice coil and a short-coil, long-gap topology, combining the power handling of large systems with the resolution of near-field monitors. ATC Super Linear technology uses specialist materials in the magnetic circuit to reduce third-harmonic distortion in the lower midrange.Dual-suspension tweeterThe 25 mm SH25-76S tweeter is designed and built by ATC. Its dual suspension removes the need for ferrofluid, so performance stays consistent over the years, and the machined alloy waveguide gives even ±80° horizontal dispersion.MOSFET class A/B amplificationThe built-in MOSFET class A/B bi-amp pack delivers 200 W to the woofer and 50 W to the tweeter. The balanced XLR input has a -12 dB sensitivity trim, and ATC protection momentarily reduces gain on overload, shown by a front-panel indicator.
