Product Description
- iFi was born in 2012 with one goal in mind: to produce ‘ultra-fidelity’ audio products that push the sonic envelope whilst still priced within the mainstream.
- iFi audio is under our parent company, AMR, Abbingdon Music Research, which designs and produces top-end luxurious audio products. AMR saw in 2010 that customer demand for wireless and portable headphones was expanding as the whole audio dynamic was changing. Thus, iFi was launched.
- iFi offers small but prodigious personal audio products thanks to the superior knowledge of AMR’s technology. Today, we are proud of our British (and international) roots. We continue to design and produce over 35 different products. We are headquartered in Southport, UK with distribution including retailers such as B&H and etailz with production overseas.
- We source parts from around the world from manufacturers including AMOS (UK), GE Valves (USA), WIMA (Germany) and TDK (Japan).
iSilencer+ C-A
Uniquely, it does this by combining passive filtering with iFi’s ANC II (Active Noise Cancellation II) circuit. Developed from military radar technology, ANC II works in a similar way to active noise-cancelling headphones – it generates a signal identical to that of the incoming electrical noise but in the opposite phase, actively cancelling it out. This is highly effective at removing low- and mid-frequency noise, while passive insulating filters deal with higher frequency interference. This combination is measurably more effective at eradicating noise corrupting the USB signal than devices relying solely on passive filtering.
The more the merrier
As well as plugging an iSilencer+ into the active USB output between computer and DAC, more iSilencer+ ‘sticks’ can be plugged into spare USB ports to further reduce radiated EMI. Each time the number of units (and therefore the number ANC II circuits) is doubled, noise reduction capability also doubles. And the iSilencer+ can be used between external hard drives and music servers, too. The precise effect of the iSilencer+ on sound quality varies from system to system; typically, one can expect to hear more clarity, greater dynamic extension and sharper leading edges, making the music sound more vivid and open.
IFI AUDIO iSilencer + Type C > Type A ได้รับการพัฒนาจากเทคโนโลยีเรดาร์ทางทหารซึ่งทำงานในลักษณะเดียวกันกับหูฟังตัดเสียงรบกวนที่ใช้งานอยู่โดยจะสร้างสัญญาณที่เหมือนกับสัญญาณรบกวนทางไฟฟ้าที่เข้ามา คือการรวมการกรองแบบพาสซีฟเข้ากับวงจร iFi’s ANC II (Active Noise Cancelling II) ANC II เสียบ iSilencer + เข้ากับเอาต์พุต USB ที่ใช้งานอยู่ระหว่างคอมพิวเตอร์และ DAC จำนวนวงจร ANC II จะเพิ่มขึ้นเป็นสองเท่าความสามารถในการลดสัญญาณรบกวนจะเพิ่มขึ้นเป็นสองเท่า รขยายแบบไดนามิกที่มากขึ้นและเสียงคมชัดขึ้นทำให้เพลงมีความสดใสมากขึ้น
