HOW TO CHOOSE iSilencer+ | Enhancer?

It uses iFi Active Noise Cancellation2 tech to decrease noise by 100x or -40dB in comparison to the common noise filter ...

Professional Audio

*****

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.

bit-perfectIf a file is "Bit Perfect’ it means it has stayed the same. For example, if a PCM file is played through a DAC to improve the sound quality and the DAC does not change the file format. The file is ‘Bit Perfect’.

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+.

Take a look at our Noisebusting Tech Note.

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.

DAC (Digital-to-Analogue Converter)DACs convert digital information, stored or streamed by computers, into music we can hear through speakers or headphones.
Every device that’s a source of digital sound has a built-in DAC (TVs, games consoles, CD players, phones, portable music players etc). Dedicated external DACs sound much better than standard DACs used in digital devices such as phones.
EMI (Electromagnetic Interference)EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.
RFI (Radio-frequency interference)Radio-frequency interference (RFI) is very similar to electromagnetic interference (EMI) but is found in the radio frequency spectrum. It is another source of irritating, unwanted noise often talked about as an ‘audio gremlin’.

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.

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.

Active Noise Cancellation®

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.

SuperSpeed USB 3.0

‘SuperSpeed’ USB 3.0 has a more exhaustive wiring specification which allows for a greater amount of audio transfer while still being backwards compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.

REBalance

REBalance® literally rebalances the signal to address the common problem of clicks caused by jitter. This is a form of digital distortion that leads to data ‘packet’ errors and cold harsh sound.
Our technology re-balances the signal to ensure that the digital signal received by the DAC is identical to the original source, no matter which audio format is being played.

Active Noise Cancellation II® (ANC II) tech

Enjoy the silence! Our Active Noise Cancellation II® (ANC II) tech means that measured noise drops by 100x or 40dB in comparison to the common noise filter.
