The ATC SCM25A Studio Monitors brings the quality of the ATC 3-Way monitor systems (like the SCM50 and SCM150) to a much smaller footprint!
The ATC Loudspeakers SCM25A Pro features a 1" HF driver, 3" proprietary mid-dome, and 7" proprietary short coil carbon paper woofer. The famous low distortion ATC technology is apparent throughout-- including the 4th order critically damped, phase compensated crossover, and passively cooled, FET limited amplifier block. The integrated tri-amplifier provides 150W to the woofer, 60W to the Mid Dome, and 25W to the soft dome tweeter, and has 0 to +6dB bass boost control, as well as a 0 to -6dB input trim. Also provided is a foam port bung to reduce low frequency output in small listening/control rooms. The port bung will give -1.5dB attenuation, centred on 80Hz. Output below 45Hz will increase by approximately 1dB. There will be an optional rackmount system, also provided by ATC, when needed for Broadcast and Television applications.
The SCM25/50/100/110 and 150 are a range of three way loudspeakers. All of the range, excluding the SCM25 are available as passive or active units, the SCM25 is only available as an active unit. Passive units have an SL suffix and active units an ASL suffix. Passive monitors are equipped with a “tri-wire” connection panel to enable separate amplification of the bass, mid and high frequency drivers. Active units have a built in three way Amplifier with frequency, gain and phase correction which has been individually optimized at the ATC manufacturing facility. Adjustment of input sensitivity and bass boost are available to the user via controls on the rear panel of the unit.
ATC was founded in London in 1974 by Australian emigre Bill Woodman, who still heads the company today. An enthusiastic pianist and engineer he was naturally drawn to loudspeaker design and after a period working at Goodmans, where many of the names that went on to found British loudspeaker companies began their careers, he struck out on his own.The premise on which ATC began is a simple one, and one that in many respects is still true today: hi-fi loudspeakers tend to be detailed and accurate but of limited dynamic range, while professional monitor speakers tend to express the opposite character. ATC products were designed from the outset to offer the best of both. It’s an easy concept to describe, but surprisingly difficult to engineer
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.
