iFi Audio iSilencer+ - Audiophile USB Noise Reduction / Remover / Eliminator

Sự miêu tả Nhận xét

Does your USB audio system suffer from annoying background noise?Our new and improved iSilencer+ is a must if you want to enjoy vivid, open music.

Enjoy the ‘new’ silence.

Connecting audio gear via USB can have pros and cons. While capable of passing hi-res data at max resolution and allowing bit-perfect transfer, USB was not created specifically for audio.

It carries both power and data. It is susceptible to electrical noise, for example, from the computer’s power supply. This has a negative effect on sound quality.

Fear not! At iFi, we first banished these gremlins with the iSilencer3.0 and now, we’re making silence sound even better with the iSilencer+.

Plug. Play. Pop free.Electrical noise on USB causes errors, data loss and poor signal integrity. You will hear these as distortion – pops, clicks and delays.

The iSilencer+ solves all of this quickly and easily. It plugs directly into the USB port of your computer as a link between your computer and your DAC.

It will remove electrical noise, both EMI and RFI, at source. Your music will seem clearer, warmer, and more transparent with improved bass.

Double whammy.

As well as plugging the iSilencer+ into the active USB port between the computer and DAC, it can also be plugged into unused USB ports too. This will further reduce radiated EMI.

Each time the number of units (and therefore the number ANC II circuits) is doubled, noise reduction capability also doubles.

Double whammy.

Silence. Improved.The iSilencer+ uses our latest Active Noise Cancellation II® technology. It decreases noise in a similar way to noise-cancelling headphones.

We use our REBalance® tech to get rid of clicks and distortion.

We’ve upgraded the circuitry; low-ESR tantalum capacitors have been added for improved input and output filtering. Filtering capacitance has been increased 10-fold.

Why iSilencer+?

We’ve added several flavours – it comes in 3 versions and includes the newer USB-C connector.

USB-A to USB-A
USB-C to USB-A
USB-C to USB-C

Why did we name it iSilencer+? Simply because it just gives you more – more options, improved filtering, and just more silence.

Based on military tech, our improved Active Noise Cancellation II® actively cancels all incoming noise.

It does this 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.

It reduces the noise floor by > 40dB (> 100x).
