ATC音响，是英国制造商，专业生产扬声器单元，完整的音响重播系统，包括相关的电子设备。所有的系统和部件的设计和制造都出于自家，实现远远超过了行业标准的性能水平。这是通过採用完全专业化的工程方法的基本设计，材料科学和生产技术的问题上取得的成果。
它成立于1974年，是由一个叫比利，伍德曼的人生产传统的单元被用在专业的声乐工业中。ATC很快地由于12寸的 PA75-314的驱动单元赢得的市场，它是一款能在很高的声音压力的情况下，提供很强能量和驱动，但是很少失真的的一款单元在当时的市场上。 在1976年，首款具有开拓意义的一款SM75-150S 软球顶的中音单元（我们叫馒头中音）被生产出来了，它是一款具有技术上的力作，它的革新设计使得能产生出更加统一的声音离散，更高的频带宽度，并且比但是市场上任何一款单元更低的失真。
它彻底革新了监听水平，并且从此这款单元被认可在国内和专业领域中。它使用特殊的材料和精确的误差，最后版本的SM75-150S 象征着最尖端的单元制造工艺和水平。
她经常被模仿，但却从没有被超越。
它在接下来的十年中，目睹了整个扬声器系统的引入，并且进一步的版本PA单元应被很多先进的扬声器厂家应用在在OEM的形式中，例如PINK FLOYD, SUPERTRAMP就是他们的早期客户。在这一段时期，ATC发明并发展了第一个主动系统要素，引入了EC23 电子分频技术相位矫正技术中。和DANISH RADIO 便携式监听器合同中，它提供了一种整合系统的机会。随着更好的微调，他被保留在当今专业和民用HIFI领域中大量应用。
由于它在市场上建立具有参考级别和精确的标准，一系列的更小的小箱子被孕育而生，其中包括了ATC SCM7(俗称小七），一直到10S, 20S. 在现役的和过去的版本中，对于很多新的客户，它提供了ATC 最顶尖的水平和可靠度。
1996年，ATC第一个独一无二的发烧友俱乐部被成功启动了。 包括SCA2前置驱动和SPA2-150功率放大器和 最新的SIA-150，根据ATC那种从不妥协的哲学理念，追求自身所能达到的最高的数据演绎水平被生产和制造中。在最近的版本中，他们继续提供无双精确和水平。
在同一年中，Billy Woodman和他的设计团队发明了一种革新的单元驱动技术，他去除了磁滞现象作用，被认作是在扬声器单元中具有重大意义的失真来源。运用新的材料从现代通讯领域中，ATC超级线性驱动减少了第三谢振波失真10－15DB 在100HZ和3HZ中。 辩证的说，在过去的15年中，这是最具有重要意义的变化器的发明，SL这个技术集中体现了ATC在声乐质量上的承诺。SL 驱动的精确性能够准确的演绎钢琴声和磁性的元素保持至今。
虽然ATC在多通道母带后期制造和在专业音响领域中直灌播放系统的重要保证，例如，SONY,TELARC。 ATC设备被安装在世界最高级的多通道的音乐厅和礼堂中。在世界上任何一个最优秀的声乐地方，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.
