ATC音響，是英國制造商，專業生產揚聲器單元，完整的音響重播系統，包括相關的電子設備。所有的系統和部件的設計和制造都出于自家，實現遠遠超過了行業標準的性能水平。這是通過採用完全專業化的工程方法的基本設計，材料科學和生產技術的問題上取得的成果。
它成立于1974年，是由一個叫比利，伍德曼的人生產傳統的單元被用在專業的聲樂工業中。ATC很快地由于12寸的 PA75-314的驅動單元贏得的市場，它是一款能在很高的聲音壓力的情況下，提供很強能量和驅動，但是很少失真的的一款單元在當時的市場上。 在1976年，首款具有開拓意義的一款SM75-150S 軟球頂的中音單元（我們叫饅頭中音）被生產出來了，它是一款具有技術上的力作，它的革新設計使得能產生出更加統一的聲音離散，更高的頻帶寬度，并且比但是市場上任何一款單元更低的失真。
它徹底革新了監聽水平，并且從此這款單元被認可在國內和專業領域中。它使用特殊的材料和精確的誤差，最后版本的SM75-150S 象征著最尖端的單元制造工藝和水平。
她經常被模仿，但卻從沒有被超越。
它在接下來的十年中，目睹了整個揚聲器系統的引入，并且進一步的版本PA單元應被很多先進的揚聲器廠家應用在在OEM的形式中，例如PINK FLOYD, SUPERTRAMP就是他們的早期客戶。在這一段時期，ATC發明并發展了第一個主動系統要素，引入了EC23 電子分頻技術相位矯正技術中。和DANISH RADIO 便攜式監聽器合同中，它提供了一種整合系統的機會。隨著更好的微調，他被保留在當今專業和民用HIFI領域中大量應用。
由于它在市場上建立具有參考級別和精確的標準，一系列的更小的小箱子被孕育而生，其中包括了ATC SCM7(俗稱小七），一直到10S, 20S. 在現役的和過去的版本中，對于很多新的客戶，它提供了ATC 最頂尖的水平和可靠度。
1996年，ATC第一個獨一無二的發燒友俱樂部被成功啟動了。 包括SCA2前置驅動和SPA2-150功率放大器和 最新的SIA-150，根據ATC那種從不妥協的哲學理念，追求自身所能達到的最高的數據演繹水平被生產和制造中。在最近的版本中，他們繼續提供無雙精確和水平。
在同一年中，Billy Woodman和他的設計團隊發明了一種革新的單元驅動技術，他去除了磁滯現象作用，被認作是在揚聲器單元中具有重大意義的失真來源。運用新的材料從現代通訊領域中，ATC超級線性驅動減少了第三謝振波失真10－15DB 在100HZ和3HZ中。 辯證的說，在過去的15年中，這是最具有重要意義的變化器的發明，SL這個技術集中體現了ATC在聲樂質量上的承諾。SL 驅動的精確性能夠準確的演繹鋼琴聲和磁性的元素保持至今。
雖然ATC在多通道母帶后期制造和在專業音響領域中直灌播放系統的重要保證，例如，SONY,TELARC。 ATC設備被安裝在世界最高級的多通道的音樂廳和禮堂中。在世界上任何一個最優秀的聲樂地方，你就能找到ATC。
Formed in 1974 by Billy Woodman to manufacture custom drive units for the professional sound industry, ATC quickly made its mark with the 12" PA75-314 driver, a design capable of handling more power and producing less distortion at a higher sound pressure level than any other unit on the market.
1976 saw the first production of the ground-breaking SM 75-150s soft dome midrange driver, a technical tour-de-force, whose innovative up-scaled design reproduced a more uniform dispersion, wider bandwidth and much lower distortion than was thought possible at the time. It revolutionised studio monitoring and has since become recognised as the ultimate mid-range transducer for both domestic and professional applications. Utilising exotic materials and precision tolerances, the latest version of the SM 75-150s represents the apex of drive unit technology. It is often copied but never equalled.
The next decade witnessed the introduction of complete speaker systems and further versions of the high power PA drive units used in OEM form by many leading manufacturers and performers – Pink Floyd and Supertramp were early customers. During this period ATC researched and developed the first active system elements, introducing the EC23 Active Crossover with built in phase correction. A contract with Danish Radio for an active portable monitor provided the opportunity to integrate the new SCM50 and SCM100 speakers with a Tri-amp pack and electronic crossover to create the industry standard SCM50A and SCM100A, the first reliable and accurate active systems. With regular fine tuning they remain as popular today in both professional and hi-fi applications.
Having established a market for reference quality precision-made monitors, a succession of smaller ATC speakers then evolved, ranging from SCM7s through 10s and 20s. Available in both active and passive versions, they offered elite ATC performance and reliability to many new customers.
1996 welcomed the launch of ATC's first stand alone audiophile electronics. Both SCA2 pre-amplifier, SPA2-150 power amplifier and later the SIA2-150 were built according to ATC's no compromise philosophy, achieving performance figures that still rank as among the best available. In their latest versions they continue to offer unrivalled precision and performance.
In the same year Billy Woodman and his research team developed an innovative new driver topology designed to eliminate the effects of magnetic hysteresis as a significant source of distortion in loudspeaker drive units. Utilising a new material from the communications industry, ATC's Super Linear (SL) driver reduced third harmonic distortion by 10-15dB between 100Hz and 3kHz. Arguably the most significant development in transducer design in the last 15 years, SL technology epitomises ATC's commitment to sound quality. The SL drivers' accuracy in reproducing piano and male vocals remains unique.
Through ATC's commitment to multi-channel mastering and its direct involvement with leading players in the professional audio industry including Sony Music and Telarc, ATC's products are installed at some of the world's most prestigious multi-channel studios and auditoria. Where ever the best is required you will find ATC.
