Before
any part is utilized in a THOR interconnect, it must pass
rigorous testing. Each connector must tolerate the extreme
heat generated by the melting of silver solder at the point
of termination. Each interconnect is calibrated to control
high frequency roll-off behavior, group delay characteristics,
resonance, and impedance behavior into a wide range of its
intended load conditions. Proper strain relief is also a crucial
factor in our interconnect design. It is important that the
wire and connector have a seamless integration. Every pair
is matched and tested for continuity and fit. All of these
processes are done by hand, one interconnect at a time. This
combination of quality parts and craftsmanship allow Philex
to offer a lifetime guarantee against all manufacturers defects
under normal use.
The
interconnect performance addressed by THOR are:
Impedance Stability
and Interconnect Flexibility
The impedance of an interconnect is, in the large part, determined
by the interconnect's geometry and the material from which
the centre insulator is made. The dimension between the centre
conductor and the shield of the interconnect, as well as the
diameter of the centre conductor, all influence the interconnect's
capabilities. During installation, as interconnects are bent,
the internal segments (conductors, shields, insulators, etc.)
must shift independently to allow easy movement. If the various
layers of the interconnect do not slide easily over each other
the dimensions between the layers can be altered which changes
the impedance. Impedance changes affect the interconnect's
ability to accurately conduct signals and cause negative effects
on the interconnect/component interface.
Conductor material
and purity
Most conductors and braided
screening in the THOR Interconnects are manufactured from
Oxygen Free Copper. The special non-contaminating insulation
seals the conductors from air and moisture to prevent oxidation.
Dielectric core construction
During the development
of the THOR range, we researched the ideal insulator materials
and design of a particular interconnect. Years of testing
and improvement have resulted in a dielectric molecular composition
that not only minimises dielectric absorption (mainly effecting
the inner detail in your music) but also prevents response
overshoot, which occurs in many standard high frequency insulation
materials that were not optimised for audio and/or radio frequencies.
Our insulating dielectric material consists of Foamed PE,
which exhibits a very uniform response from DC to well into
the Giga Hertz frequency range. We employ Foamed PE core extrusions
for optimal conductor placement and low capacitance, resulting
in very low energy storage and neutral sonic characteristics.
The special materials used in our interconnects were originally
derived from our satellite interconnects, which are well known
on the market for their ability to withstand wide temperature
fluctuations in all weather conditions year in year out. The
use of this technology for AV interconnects guarantees them
to sound the same years from now as they do today; detailed,
accurate, clean, and as full range as a interconnect can possibly
be.
That is what makes our interconnects sound as good with 10
meter runs as they do in 1 meter lengths.
Gold-plated, Solid Brass Connectors
Every THOR Connector has been carefully designed and machined
from solid brass and then plated with gold for protection
against the potential for the deteriorating effects of contamination,
corrosion resistance and good conductivity. The THOR connectors
also provide maximum contact area which maintains maximum
electrical connection to the system component to ensure uncompromising
signal transfer and protection from atmospheric contamination,
yet, allows ease of use. The result is enhanced signal transmission.
The parameters that determined
the construction of the THOR connectors are:
1. Complete metal construction to shield out any stray signals
that could cause sound colourations.
2. Super non-conductive insulator between connector pins and
ground.
3. Directional arrows on the connectors where the direction
of travel of the signal has been optimised to flow in the
direction of the OFC atomic flow.
Shock absorption cord grip and
interconnect flexibility
All too often overlooked by
other engineers, but a very important aspect of a good interconnect
design. Most interconnects are mishandled during installation,
which can result in a far less satisfying level of performance
compared to expectations.
The impedance of a coaxial interconnect
is, in the large part, determined by the interconnect's geometry
and the material from which the centre insulator is made.
During installation, when interconnects are bent, the internal
segments (conductors, shields, insulators, etc.) must shift
independently to allow easy movement. If the various layers
of the interconnect do not slide easily over each other the
dimensions between the layers can be altered which changes
the impedance. Impedance changes affect the interconnect's
ability to accurately conduct signals and cause negative effects
on the interconnect/component interface. The THOR interconnects
have received special attention in this area to cut down drastically
on such mishaps.
Grounding
A solid gun metal plated casing
bonded to the passive shield and ground return path prevents
contamination of the audio signal from radio frequency interference
(RFI) and electromagnetic interference (EMI). Cold welding
of the shield to connector body ensures a very low resistance
ground connection. The substantial surface area and weight
of the ground plane offers a far more stable platform that
acts as the ideal ground reference. Signal distortions due
to floating earth problems are therefore unheard of, compared
to lesser quality leads.
Braided and solid shields for better noise reduction
Today's
sophisticated home entertainment systems have far greater
susceptibility to noise radiation and extraneous signal pickup.
Our interconnect designs offer
superior RFI and EMI noise rejection, that are smaller than
the measuring equipment we employ. Having a perfect shield
and interconnect geometry are absolute necessities, given
the proliferation of noise sources in today hi-tech electronics
and wireless devices. Only the most advanced materials, construction,
and shielding methods can overcome this increasingly complex
problem. To achieve a high degree of noise reduction, we use
numerous methods of multiple shielding to make it possible
to direct up to 100% of the electronic noise away from the
program carrying conductor thus achieving the fundamental
purpose of shielding.
Termination
Terminations were designed
to allow for a direct, positive, hand-soldered and crimped
connection of the terminating wire to the interconnect, with
a minimum gap at the termination points. This careful planning
allows for the full advantage of the interconnect to be heard.
Special solder alloys and methods were adopted from many years
of experience to mate with our interconnects and squeeze every
last detail out of these unique designs.
Polyvinylchloride (PVC) outer Jacket
A rugged PVC
jacket surrounds these exceptional interconnects for flexibility
and protection from abrasion damage and deterioration caused
by seasonal temperature changes.
Micro Wind Design
Our micro wind design maintains constant internal wire geometry
and assures uniform and constant impedance characteristics,
which is required for precise signal transfer and also allows
for installations once considered prohibitively long.
Hot Soldering Connection
Hot soldering
connection provides a powerful strain relief and ensures
the best contact and intermittent-free operation over
time. It achieves the strongest mechanical and electrical
connections between the interconnect and the connector
at the point that is most vulnerable to mechanical
failure by binding every interconnect strand together. This
method has proven to be more reliable than the cold soldering
system that only makes contact with the outer conductors,
but still fancied by some other interconnect manufacturers. Repeated stress
on a cold soldered connection causes failure of the mechanical
connection between the strain relief and the front
end of the connector, which will eventually lead to reduced,
loss of, or completely no sound.
Silver Solder
All THOR Interconnects are manufactured
using solder with a high silver content for best conductivity.
