Z-Sleeves are not ferrite or resonance-control based. Rather, they are designed to approximate a Zero Gauss Chamber. The tube creates an internal magnetic null area that completely obliterates EMI contamination. This is accomplished through the specific combination of shielding materials, dimensional ratios and increased abilities of those shields to hold and store EMI.

A Z-SLEEVE is a ZERO GAUSS Tube, that slips over a cable. It does not connect to the cables in any way, and does its effect passively, not in circuit.

The Z-SLEEVE is 8 inches long, with an internal diameter of 1 1/8th inches.

Most speaker cables slip through the sleeve without any problem. If your speaker cable leads are long enough, then putting Z-SLEEVEs over the leads themselves is most effective, if not put the sleeve over the body of the speaker cable (placing the sleeve closest to the speaker).

On an interconnect or coax digital cable, the sleeve slips over the top of the cable and is placed closest to the receiving component.

The Z-SLEEVE reduces distortion, and focuses the signal just before it goes into the speaker or receiving component. It does this through passive organization of the Concentric magnetic field surrounding, and propagated by the speaker cable’s signal.

The Z-SLEEVE will reduce high frequency noise, increase Mid and Bass definition, improve coherence, improve spatiality, and improve dynamics.


1. A Frequency Linear Zero Gauss Chamber 
A Zero Gauss Chamber (ZGC) is normally used by electrical engineers or technicians for calibration of Gauss Meters and other devices that measure magnetic fields. Of all shapes, a cylindrical design is one of the most efficient for magnetically shielding a finite space. The multiplying effect of successively spaced shields provides substantially greater magnetic attenuation than a shield of equivalent solid thickness. However, a ZGC can reach a saturation point of magnetic storage, at which time their effectiveness is reduced. So part of the Z-SLEEVE design was to reduce magnetic saturation by increasing the sleeve's ability to store magnetism.

Sleeve Harmonics
By putting any conductive sleeve around a signal or power cord, you will change the tonal balance and tonal harmonics of the cable. We spent eighteen month to create ZGC sleeve ratios of diameter, length, and thickness which have balanced effects across the audio, digital, and video spectrums. During this time, much testing of metals, plated metals, and metal alloys were tested for optimum frequency and tonal balance. It should be noted that the tonal balance of a normal ZGC is slow, thick, and lacking in upper frequency detail. Our research in sleeve harmonics allows us to use to positives of a ZGC while eliminating any of the negatives.
The result is that the signal is organized, or focused by the sleeve harmonics. This is one of the reasons that using a Z-SLEEVE just prior to going into a component is usually most powerful. 

There is a concentric electromagnetic (EM) field that spins perpendicularly to the direction of a signal traveling through a cable. The Z-SLEEVE harnesses and manipulates that field to speed it up and to organize it. This action has a resulting effect of organizing the signal. Secondarily, the Z-SLEEVE "wicks" out of the field the electromagnetic interference (EMI) noise, so the music signal becomes more pronounced. This occurs because the concentric EM field spins in materials "sandwiched" in between EMI absorptive materials and material that facilitate the EM field rotation. So it cleans as it organizes. 

The Z-SLEEVE does not introduce it's own EM field. It uses the EM field of the signal or power cable to create its effect. This way no distortion is created. If it was an active device, which would introduce its own EM field, the possibility of signal distortion would be very high. It is also very important for the concentric field to be passively generated by the signal. For in this way it increases automatically as the signal increases! Various cables carries very different amperages, from .0001 amp to 100* amps. Since the sleeve reacts to the field generated by the cable, it gets more powerful when the signal is more powerful. This reactive nature also is imperative to the "no distortion" design. You can imagine the distortion that a high concentric field would create on a .0001 amp interconnect signal. Think of it as an EM lens. 

A Z-SLEEVE is more than just a shielding device. It organizes and purifies the signal. Here is a simple test anyone can do - take two speaker cables: one cable 10 ft long, and the other 20 ft long. Hook them up to a stereo and play a mono signal. Listen. The shorter speaker cable should be slightly better. Now put 2 Ultra1 Z-SLEEVES on the longer (20 ft) speaker cable near the speaker. If the Z- SLEEVE is only a shield, and you are therefore only shielding 16" of the speaker cable; the shorter speaker cable should still sound slightly better. It won't. The longer speaker cable with 2 Ultra1 Z-SLEEVES will sound noticeably better. It will sound less distorted, more natural, less synthetic, and more tonally coherent. 

The Z-Sleeve not only blocks and absorbs the stray EMI fields, it conditions the signal within the cable as well. The result is less distortion and better, much better, sound.http://www.claritycable.com/images/z-sleeve-anatomy.gifshapeimage_1_link_0
