Gemini USB cable by iFi audio

Generic USB cables are not optimised for the highest quality audio. The Gemini is. Separation of audio and power.

Beat sound and signal distortion with the Gemini cable – two heads are always better than one.

The power of Two

The Gemini dual-headed cable is for those discerning users who prefer their music as interference free as possible.

In most mass-produced USB cables, the signal and power cables are normally compacted together. This means that they do not conduct as well as they should nor are they protected from one another.

This leads to interference and hampers quality.

A cable divided

The Gemini cable carries the audio signal and power in two separate cables.

This separates the delicate USB data signal from the USB power.

No interference and sound quality remains unaffected.

Superior design. Better signal. Strong shielding.

We strictly adhere to the usb.org specifications. A key factor that is often overlooked is sticking to the 90 ohms impedance. This is achieved using the following exhaustive methods.

We use heavy OFHC continuous copper silver matrix conductors for the best possible signal transfer. The cable construction is a custom minimum inductance parallel type with dual shielding. This protects the cable from RFI and EMI noise and provides the cleanest transfer medium possible.

With the machined FINAL connectors and atypical RF3 filter designs, the iFi Gemini sets a whole new sonic benchmark for computer audio transmission.

Two heads are better than one

The power cable is heavier gauge than often found in standard USB cables. And signal and ground have their own respective geometry for optimal conductivity.

There are dual-headed designs and then there is the Gemini Dual-Headed design. Nothing comes close.

Excellence. From start to finish.

The signal runs through the cable and the connector. This means the connector too must be exceptional.

Most USB cables use moulded plastic covered connections that do not shield the high frequencies present in the USB data link. Noise radiates out. Very few make their own connectors and rely on off-the-shelf components. These often lack durability.

Our FINAL USB connectors provide impeccable end-to-end RF shielding. They are machined entirely from solid, aircraft-grade aluminium.

The USB protocol is outlined in a technical paper onthe usb.org website.

We have pored over this paper to ensure that we have closely followed the tight tolerances/specifications. For example, a major specification is adhering to 90ohms impedance.

All iFi cables have been designed with this in mind.

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’.

Top tip: just don’t add water.

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.

Most standard USB cables do not address RF issues and are fitted with filters that work over too narrow a range and are only fitted at the ends of the cables, leaving the length of the cable to act as an antennae.

iFi’s three custom-made metal oxide ceramic filters have a different effective range to broaden the range over which RF noise is silenced. The middle silencer is adjustable and can be moved along the whole length of the cable. This then “detunes” the antennae formed by the cable. The other two silencers should be kept as close to each respective end as possible.
