ETI BULLETPLUG®

RCA CONNECTOR

The ETI BulletPlug® is a totally new
approach to RCA/phono connection
in which every aspect of electron flow
has been considered.

The result is an RCA compatible connector that can
improve the performance of any analogue, digital or video
cable — often dramatically.

The ETI BulletPlug® represents a radical departure from
conventional RCA designs. Rather than overwhelm
the user with mass, thickness, and a jewelled contact
surface, the ETI BulletPlug® is a minimalist design in which
thickness, mass, materials, and contact surface area have
been optimized for better sound, higher resolution video,
and enhanced signal integrity. Listening was a major part
of its development.

Most audio/video cables are made from highly conductive
annealed copper or silver wires — terminated with low­conductive, nickel and gold-plated brass RCA plugs.
Annealed copper has a conductivity rating of at least 100%
IACS (International Annealed Copper Standard). Brass has
a conductivity rating of 28% IACS.

Because of this low conductivity, we believe conventional
RCA plugs act as a bottleneck to electron flow. These
plugs may also cause phase errors and smearing through
mass and skin effect.

Another problem relates to the return/ground collar which
can impair electron flow through:

• Eddy current distortion — as electrons proceed to and
from the RCA socket into the collar through multiple
contact points the equivalent of electron turbulence
occurs. Signal degradation results

• Capacitive distortion — where gaps exist between the
socket and collar

• Micro-arcing distortion — an electrical short that can
occur where gaps exist between the socket and collar

Additionally, RCA plugs are coaxial designs (metal return/
ground surrounding signal pin) that have an impedance
effect. This impedance can have a varied and adverse
impact on performance.

The ETI BulletPlug® solves these problems by providing a
faster, cleaner signal of high purity and detail. To achieve
this we have designed the BulletPlug® as a miniature
cable — with high-conductive, gold-plated tellurium copper
(CuTe) pins—as our standard product—providing rapid
transfer of electrons to and from RCA sockets.

Additionally, the ETI BulletPlug® features direct 24k
gold flashing over the tellurium copper conductor. This
eliminates the nickel plating typically found on even the
most deluxe and expensive RCA jacks as a third (and
dissimilar) metal. The sole reason for using nickel under
gold is to provide the shiny jewelled look that makes
expensive connectors look expensive. It is not used for
sound quality or signal integrity. In fact almost everything
done to provide this look runs counter to good sound and
in fact degrades performance.

In our patented design, the return pin makes single
point contact with the side wall of an RCA socket
— concentrating electrons to one point thereby reducing
distortion. This is a similar approach to “star earthing
(grounding)” used in amplifiers.

For the ultimate in RCA/phono connection, ETI also
offers the BulletPlug® in pure silver. Utilising the same
patented RCA blueprint, the silver ETI BulletPlug® provides
enhanced conductivity for what is arguably the absolute
best level of performance available.

The contact pins are machined from hard drawn 4-nines
pure silver rods, and then treated with Caig PreservIT —
which leaves a microscopic protective coating to prevent
oxidation and enhance conductivity. Sound quality is
superb, with subtle but significant improvements over the
standard tellurium copper plug. The silver ETI BulletPlug®
is ideal for silver interconnects and any high performance
cable.

Home Theatre

The importance of the RCA plug is often overlooked in the
context of a high resolution video or home theatre system.
Yet the quality of the RCA plug can have a disproportionate
effect on the final performance of the system. This is
easy to understand when two points are taken into
consideration.

1. The delicate nature of the tiny millivolt-level signals
flowing through a system’s interconnect, digital, and
video cables

2. The number of times these signals cumulatively travel
through RCA connectors (usually low-conductive ones)
en-route to their destination

Central to the ETI BulletPlug® design was the preservation
of the delicate signals that represent the picture that
will ultimately be seen and the audio that will ultimately
be heard.

The ETI BulletPlug® has arguably
obsoleted every other RCA jack in
the world intended for use in high
resolution applications. And nowhere
is this more evident than its use in
high quality home theatre systems.
