MIT Z Trap

Z系列是MIT所推出來解決電源污染問題的產品,主要使用MIT Filterpoles技術,MIT表示最好消除電源中不必要噪訊的方法就是在那頻率的附近產生非常低的阻抗變成噪訊消除極(attenuation pole),就電源來說,就是除了50~60Hz電源頻率外的頻率,而最好的方式就是使用調校的平行線路在負載附近(Parallel AC filtering),MIT在1993年取得這項技術的專利。

Z系列除了可消除不必要的燥訊外,還有”PFC” (Power
Factor Correction)技術,透過控制AC正弦波的向位角來使電源使用達到最大效率,提升功率因素(POWER FACTOR),MIT亦在1993年取得這項專利。

左邊在說明產品使用了幾組的filterpoles(fp)的圖示,當然是越多越好,價格也越貴。右上方的圖則是市售產品與MIT Z系列產品的比較

所以這樣就很清楚本次試聽的產品那個等級比較高了,Shotgun Z Trap使用了3組Filterpoles,導體為.999999純銅與100%的屏蔽,而較高等級的Magnum Z Trap使用了6組Filterpoles,導體為極純的OCC單結晶無氧銅,並使用雙層的屏蔽,電源母頭也比較高級。

MIT Magnum Z Trap
The Magnum Z Trap features 11ga. ultra-pure OCC (continuous cast) pure copper conductors as the basis for this remarkable design. The Magnum Z Trap delivers clear, clean power that is double shielded for field coupled noise rejection. The Z Trap employs 6 parallel AC Filterpoles to trap and dissipate AC noise. Because of its unique universal IEC in, and IEC out design, the Trap can be used with any IEC power cord, in any country! Finally, a truly universal AC line conditioner and noise trap for any high performance Audio or Video application.

MIT Shotgun Z Trap
The Shotgun Z Trap contains the latest version of MIT parallel filter technology with 3 Filterpoles, built to match and to compliment the new Shotgun Z Cord III and Magnum Z Cord III reference power cords. Because of its unique universal IEC in, and IEC out design, the Trap can be used with any IEC power cord, in any country! Finally, a truly universal AC line conditioner and noise trap for any high performance Audio or Video application.
