ATC Classic Series Loudspeakers

ATC, Acoustic Transducer Company, is a specialist British manufacturer of loudspeaker drive units and complete sound reproduction systems, including the relevant electronic equipment. ATC designs and manufactures loudspeaker drive units and systems to achieve levels of performance far in excess of the industry norm. This is achieved by adopting a thoroughly professional engineering approach to the issue of basic design, materials science and production technology.

Manufactured in house to exacting tolerances, ATC’s drive units are legendary for their many design innovations. For example, all voice coils are edgewise wound ribbon, OFHC (oxygen free high conductivity), copper wire operating in a precision machined magnetic gap.

The magnet assembly also has a hole through the pole allowing air to be vented from under the dust cap reducing air flow noise at low frequencies and at the same time increasing power handling and reliability.

Coloration is minimized by ensuring that the diaphragm assembly and drive system are extremely well damped therefore eliminating unwanted resonances and the unique Soft Dome technology that features in the midrange driver used across the range was developed by ATC in 1976 and still in use to this day - its arrival revolutionised professional studio monitoring.

Remarkably today, as then, it remains the only midrange device capable of giving ultimate performance. The Super Linear Technology found in all ATC loudspeakers is equally ground-breaking. It has long been recognised that the detrimental effects of magnetic hysteresis is a significant factor in the production of distortion in loudspeaker drive units.

All ATC loudspeakers are unique not only in their ability to accurately reproduce piano but also in the precise manner they articulate the human voice.

The ATC Active range of the monitors’ ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics is truly astounding and has to be heard to be appreciated.

Bass performance is equally impressive, thanks to ATC’s professional level bass drivers that incorporates the company’s unique Super Linear Magnet technology. Bass, mid and HF drive units in the active model have their own dedicated and individually matched MOS-FET amplifiers.

ATC’s active crossover network consists of a wide band-width, electronically balanced input stage with high common mode rejection and very low distortion.

Built to give a lifetime of service and musical pleasure all ATC products carry a 6 year warranty.

ATC SCM20 Passive Loudspeaker

The hybrid design incorporates a 150mm bass cone on to which is grafted a 75mm soft dome.

The magnet assembly utilises ATC’s unique “SL” technology which greatly reduces distortion in moving coil drive units by a very significant 12-15dB (3rd harmonic). To minimise Time Domain Distortion both dome and cone are made from acoustically “dead” polyester wave material doped with ATC’s own formulation.

Not only does the SCM20SL reproduce bass with remarkable articulation and authority, it also has outstanding mid-band clarity, incredible dynamic range, and awesome power handling.

The active tower version (SCM20ATSL) is powered by the ATC “Grounded Source” Bi-amplifier. The bass/mid is driven with 200 watts, while the tweeter has 50 watts of class “AB” power.

Both amplifiers feature momentary gain reduction circuitry which both protects drive units and prevents unpleasant sounds from overdrive.

Accompanied by either ATC SCA2 or CA2 preamp the SCM20AT will out perform any other combination in its price range any many costing far more.

An all time classic still available and in any veneer to special order.

ATC SCM50 Passive Loudspeaker

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 an upgraded tweeter and enhanced port profile have brought about further improvements in 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 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.
