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+ A-A
The transfer mode used for ‘USB Audio Class’ devices is more demanding of USB hardware/software than the bulk/burst mode used for peripherals such as printers and hard drives. Error checking is present but there is no re-transmission in the event of CRC (Cyclic Redundancy Check) errors. Electrical noise on USB signals causes CRC errors and thus data loss, as does poor signal integrity. This can result in audio signal distortion, artefacts (such as clicks and pops) and latency – all things that can affect the performance of computer-based audio systems. The iSilencer+ solves this issue by removing electrical noise (including EMI/RFI) at source, thereby enabling bit-perfect transfer of audio data to the DAC.
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 A > Type A ใช้สำหรับอุปกรณ์ต่อพ่วง ป้องกันสัญญาณรบกวนทางไฟฟ้าในสัญญาณ USB ทำให้เกิดข้อผิดพลาด และทำให้ข้อมูลสูญหายเช่นเดียวกับความสมบูรณ์ของสัญญาณที่ไม่ดี ซึ่งอาจส่งผลให้เกิดความผิดเพี้ยนของสัญญาณเสียงสิ่งประดิษฐ์ (เช่นการคลิกและป๊อปอัป) ทุกสิ่งที่อาจส่งผลต่อประสิทธิภาพของระบบเสียงที่ใช้คอมพิวเตอร์ iSilencer + แก้ปัญหานี้ได้โดยการลบสัญญาณรบกวนทางไฟฟ้า (รวมถึง EMI / RFI) ที่ต้นทางจึงทำให้สามารถถ่ายโอนข้อมูลเสียงไปยัง DAC ได้อย่างสมบูรณ์แบบ
