XTRA for your FIRST UPGRADE
XTRA 3.5 mm connected cables are designed to give an upgrade in sound quality over the cables usually supplied to connect between computers, headphones and the RCA inputs in audio amplifiers.
XTRA Innovative Design is different.
We use a high-quality cable, and we add 3 of the most cost-effective upgrading techniques developed from our research into high-end cabling to deliver for you clearer sound with tighter and more controlled bass notes, smooth high frequencies, with greater depth of sound and superior stereo imaging.
We find that the extra distortion reducing components we use give better sound quality for the cost than traditional cable design based on using higher-grade cable with superior technical specifications on its own.
XTRA for FIRST UPGRADE 3.5 mm cables use 2 cores of copper conductor 0.12 sq. mm with a cotton filler covered in a plastic foil and a braided metal screen and sheathed in PVC.
Only one cable is used in cables with 3.5 mm connectors at both ends, but we use two cores for cables fitted with RCA. Two such cables are joined together in a figure of 8 construction as a stereo pair.
Conductor capacitance is 65pF per metre.
A further braided metal screen over both cable channels further substantially reduces distortion caused by external RF and magnetic fields.
An Expandable flame-retardant braided sleeve with superior acoustic dampening properties that minimize distortion caused by vibration within the cable.
A large ferrite core is fitted over the cable to minimize distortion caused by high frequency noise within the cable.
XTRA for FIRST UPGRADE cables for portables are supplied in lengths of 1m. Longer cable lengths can be supplied on request.
XTRA 3.5 mm cables are supplied in two connection formats
- 3.5mm jack plug to 3.5mm jack plug
- 3.5mm jack plug x 2 x RCA gold plated plugs
