Product Information

Full details

The iFi Audio iSilencer+ is designed for audiophiles and digital music enthusiasts looking to eliminate unwanted electrical noise, hiss, and jitter from their desktop audio signal chain. By leveraging Active Noise Cancellation, this device delivers a cleaner, more immersive listening experience for your DAC or audio interface. While it is an excellent solution for USB-based interference, users should note that it cannot rectify issues originating from poor-quality source files or internal software-based processing noise.

FAQs

Does the iSilencer+ require any drivers?

No, it is a transparent hardware device and requires no software or driver installation.

Can I use multiple iSilencer+ units in a row?

While it is physically possible, it is generally recommended to use one per signal path to avoid potential data throughput issues.

Will this device change the sound signature of my DAC?

The iSilencer+ is designed to be sonically transparent; it removes noise rather than adding coloration or altering the frequency response.

Is it compatible with USB-C ports?

You will need a high-quality USB-C to USB-A adapter if you intend to connect the iSilencer+ to a USB-C port.

Does it improve video quality?

The device is specifically optimized for audio data packets and USB power noise; it is not intended for use with high-bandwidth video devices like hard drives or monitors.

Troubleshooting

Audio playback is intermittent or dropping out

Ensure the iSilencer+ is pushed firmly into the USB port and that the USB cable connected to the DAC is securely attached.

Noise still present after installation

Confirm that the noise is indeed coming from the USB source by temporarily using a battery-powered device; if the noise remains, it may be a ground loop elsewhere in the system.

Pros and Cons

Pros

  • Significantly reduces audible background hiss and hum
  • Easy plug-and-play installation without extra drivers
  • Maintains high-speed data transfer via USB 3.0
  • Compact form factor fits easily into crowded desk setups
  • Improves transient response and soundstage clarity

Cons

  • Cannot fix noise originating from the source file itself
  • Physically extends the length of your USB connection which may require cable management
  • Does not resolve ground loop issues outside of the USB bus

Setup, Compatibility & Care

Installation is straightforward: simply plug the iSilencer+ directly into the USB port of your computer or audio device. Once connected, attach your USB cable to the other end of the device, leading to your DAC.

  • Compatibility: It is compatible with USB 3.0 and USB 2.0 ports and supports all standard high-resolution audio formats. It works with Windows, macOS, Linux, and Android devices that support USB Audio Class.
  • Care: Keep the connectors free from dust and debris. If you need to clean the exterior, use a dry, lint-free cloth. Avoid using liquid cleaners or abrasive materials. Ensure the unit is firmly seated in the port to maintain electrical contact.
