Blue Horizon Unveils Proburn - a 'cable burn-in accelerator' (10/6/2009)

New burn-in device ensures audio cables perform at their best

Blue Horizon, a new company specialising in professional-grade audio accessories,
has unveiled its first product - Proburn, a 'cable burn-in accelerator' that ensures
audio cables perform at their peak.

Here are some of the benefits of the Blue Horizon Proburn:

• Generates specific ultra-low and ultra-high frequencies to optimise cable performance
• Produces 10,000 times the upper frequency limit of a typical CD player
• Dramatically reduces the burn-in time required by new cables to within 48 hours
• More effective at optimising cable performance than music signals alone
• Keeps cables performing at their best - condition them for a period of 24 hours, every
six to eight weeks, to nullify any negative charges and static problems

Blue Horizon Proburn: The Challenge

It's a well-known fact that audio cables improve with use. A hard, closed-in sound with a
distinct lack of bass are the qualities most noted when a cable is new; a cable that has been
'burned-in' will sound more open, extended and three-dimensional, with a more natural, less
sterile performance overall.

Unfortunately, most high-quality audio cables only get close to realising their full potential
after months of use. Furthermore, though it is possible to gradually improve the performance
of speaker and interconnect cables by playing wide-bandwidth music signals through them,
they will never reach peak performance with music signals alone.

The problem with real music is that it has relatively little high-frequency energy, which limits
its ability to improve cable performance. Research shows that musical instruments may
produce energy above 20kHz, but there is little sound energy above 40kHz. In addition, few
microphones pick up sound at frequencies much higher than 20kHz.

Traditional cable burn-in techniques are also limited by the playback device. Even the best
purpose-made burn-in CDs have a limited effect, owing to the restricted frequency range of
CD players. Post-filtering, a CD is only able to deliver audio frequencies up to about 20kHz.

Blue Horizon Proburn: The Solution

The Blue Horizon Proburn is specifically designed to speed up the cable burn-in process,
and conduct this process to a higher standard than any other device currently available.
For maximum effect, it is critical to not only concentrate on the conductor, but also on the
dielectric that surrounds it. Ideally, cable burn-in needs to force electrons into all areas of the
cable; this is something that playing music through an audio system can never achieve.

The Proburn does more than simply synthesise music. Using specially developed
technology, the device generates a sequence of ultra-low frequencies to penetrate the core
of the conductor, and ultra-high frequencies (up to 10,000 times the upper frequency limit of
a typical CD player) to penetrate both the conductor and the dielectric.

Using conventional methods, it is extremely difficult to condition the dielectric of a cable, yet
this is exactly where effort should be focused. Using carefully controlled energy levels and
frequencies, electrons are forced and attempt to enter the dielectric. Imagine a highfrequency, high-energy force zipping along the conductor surface in a corkscrew fashion
between the conductor and into the dielectric; the malingering electrons and negative
charges are then forced to join the procession.

Through this technique of ultra-low and ultra-high frequencies in a musical synthesis, the
cable is fully prepared and burned-in within 24 to 48 hours. This guarantees total penetration
of the core of the cable, and also that the interface between the outer conductor surface and
dielectric is fully and properly conditioned.
