ATC SCM12 Pro/P1 Pro Package

The ATC SCM12 Pro passive monitors combined with the ATC P1 Pro dual mono amplifier perfectly compliment each other offering exceptional near-field monitoring in a compact package.

As an all-new design, the ATC SCM12 Pro proffers ATC’s acclaimed performance at a lower price point without compromising component quality and achieves this in a more compact, installation-friendly footprint ideally suited to nearfield monitoring as well as multichannel music and post-production applications.

Though the SCM12 Pro is the most affordable model in ATC’s professional range of loudspeakers, the monitor makes use of the company’s celebrated drive units for both the mid/bass and tweeter, both being meticulously hand built at its UK facility.

The tweeter is a 25mm/one-inch soft-dome designed around ATC’s unique dual-suspension technology. Unlike conventional tweeters, this precision part employs two suspensions, offering far greater control of the voice coil and dome motion — especially at higher sound pressure levels. The result is an extended high-frequency response with much greater clarity and definition due to the reduction in disturbing anharmonic distortion. Listener fatigue is also greatly reduced, resulting in users being able to work for longer periods with greater accuracy.

At the lower end of the frequency spectrum, mid/bass reproduction is handled by ATC’s 150mm/six-inch proprietary CLD drive unit. Using a 45mm/1.75-inch diameter voice coil, and employing an FEA (Finite Element Analysis) optimised high-energy symmetric gap motor system, the driver is capable of tremendous dynamic range with minimal power compression. Cone construction is courtesy of another proprietary ATC technology that represents another advance in driver performance — namely, Constrained Layer Damping (CLD), a process that uses multiple laminated fabric cones to form a stiff, light, and tremendously well-damped structure. Speaking acoustically, this construction creates a smoother on- and off-axis frequency response and also a reduction in distortion leading to a more lifelike reproduction of source material. Meaningfully, judgements and decisions can be made more quickly, more accurately, and for longer periods of time by busy working audio professionals.

Put it another way: by employing exceptional drive units, the passive crossover can, by design, use the minimum number of components in a simple, second-order implementation. Indeed, the capacitors are all 250Vdc metalised polypropylene and all the inductors are air-cored types for minimal signal distortion. Additionally, all of the inductors are wound in house with very high-purity copper while large-gauge wire is used for the bass components to minimise signal losses.

Discerning audio professionals always appreciate that exceptional passive monitors require exceptional amplification; as far as the SCM12 Pro is concerned, the best possible results will be achieved when it is partnered with ATC’s own range of stereo power amplifiers. As such, the 150Wper-channel P1 Pro dual-mono power amplifier is the perfect partner — both in terms of power output and its outstanding resolution, resulting from technology originally developed for ATC’s high-end active monitoring systems.

Simple, well-engineered products almost always trump feature-rich, cost-engineered alternatives, and ATC’s SCM12 Pro has been duly designed with that philosophy very much intact. Its neutral fidelity makes it a very versatile proposition, one which — when backed up with the company’s industry-leading six-year warranty — makes for a high-value, longterm investment for anyone looking to upgrade their monitoring system. So now is the time to consider EQ’ing, balancing, and editing faster, with more consistent results and reduced listening fatigue using the latest nearfield monitoring marvel from ATC.
