ATC SCM50 Speaker (Bookshelf)

概觀
SCM50 ASL（有源）和SCM50 SL（無源）的設計都能在錄音室或是在家裡配上最優質的音響器材達到有最佳的表現。

該監聽音箱重播音樂和語音都有驚人的準確，透明和動態的能力主要是在於SM75-150S軟半球形中音單元。但是，近期的修訂包括高音單元升級和增強倒相管口的輪廓在所有性能參數帶來了進一步的改進。

在有源型號中的每個驅動單元都有自己專用並單獨匹配的MOS-FET放大器，而234mm/9“低音單元採用了ATC獨特的超線性磁體技術。我們的有源電子分頻器包含一個寬的頻帶寬，高共模抑制比和極低失真的電子平衡輸入級。

就像高、中和低音驅動單元一樣，所有電子部份的設計和製造都是自家生產創造一個不妥協的主動系統。在無源型號，SCM50 SL提供廣泛的和對稱的分散性，在整個頻率範圍內有優異的振幅和相位特性。

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 the new ATC SH25-76S tweeter and enhanced port profile have brought about further improvements to 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 HF, 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.
