The iSilencer3.0® is the most direct and simple upgrade for any USB port, it lowers noise/RFI/EMI by up to 40dB or 100x.

It is ideal for the home and on-the-go improvement of all devices connected to the USB port, e.g. Computer Servers, Mixers, Hard drives etc. Regardless of the system; from £10,000 to £100, the iSilencer3.0® terminates noise, in its tracks.

Active Noise Cancellation® by AMR/iFi is in-house technology developed to cut out noise in a very significant way in the audio field. It is now the bedrock of iFi signal/power products because…they need to address the issue of noise in both signal and power situations.

What is the Active Noise Cancellation circuit design?

Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation® (ANC®) audio power system. It is now a cornerstone of the ever-improving iFi USB audio technology, looking for new products to feature ANC® ,and ANC+®.

An air defence radar is transmitting at a certain frequency; the signal is bouncing off the aircraft; a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, out-of-phase signal is generated by an on board system to cancel out the enemy radar signal.

By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC® is the perfect ‘antidote’ for power supply noise, the bane of USB audio.

ANC® measured, noise drops by 100 times or 40dB in comparison to the Common Noise Filter. Sonically, the background and inner resolution to recordings is enhanced.

The iSilencer3.0® can be used not only at the active USB ports but also at unused USB ports where it will reduce radiated EMI and as the ANC® circuitry is bi-directional and usually as all USB ports share one power bus. The iSilencer3.0® cuts noise, system-wide for all USB ports, including for example an active port that has another iSilencer3.0® plugged-in which is the one connected to another device.

Multiple ANC® circuits will simply double the noise reduction each time the number of ANC® units is doubled. So 2 x iSilencer3.0® will kill double the noise of a single-one and four for example will kill four times the noise of a single one; if they are plugged into the same block of USB Ports and even though only one iSilencer3.0® has one device (e.g. DAC) connected into it.

It is now a hallmark of all the latest iFi signal and power products to be USB3.0 standard. First USB3.0 is backwards compatible with USB2.0. Second, in terms of the specifications, USB3.0 is superior to USB2.0 e.g. the wire gauge specification is more exhaustive and the connections are better.

Hence, the iSilencer3.0® is USB3.0 standard but also 2.0 compatible.
