R3X ISOLATION BASE
A Low Noise Floor Is Fundamental

2
Introduction
Thank you for purchasing the Harmonic Resolution Systems R3X Isolation Base.
When used properly, it will give you many years of superior musical or video
signal reproduction.
The R3X Isolation Base significantly reduces the negative impact of structure
borne vibration on your audio or video component performance. Many years of
engineering experience, custom material development, and listening tests are
incorporated into the design of the R3X Isolation Base. The performance of the
R3X Isolation Base will enable your audio/video source and amplification
components to achieve a very high level of performance.
The R3X Isolation Base is an excellent match with HRS Damping Plates, Nimbus
products, Vortex, and Helix. While the R3X Isolation Base works to significantly
reduce structure-borne vibration, the HRS Damping Plates, Nimbus products, and
Vortex products, and Helix significantly reduce the harmful effects of airborne
vibration and structural resonance on your components.
Please read this manual completely prior to use of your R3X Isolation Base for
setup and product care instructions. Proper care of your R3X Isolation Base will
ensure optimum performance and an aesthetically pleasing appearance.

Safety Instructions
IMPORTANT WARNINGS!
Do not place any tall objects on the isolation base. A tall object is any object with
a height that is greater than the length of the isolation base. A tall object is also
any object that has a height greater than its own width or length. Tall objects must
not be placed on top of the isolation base for any reason. The object may become
unstable and tip over causing damage to the component, adjacent objects, or
injury to people.
Lifting or moving the isolation base should always be done by means of the outer
rectangular frame. Do not lift the isolation base by the external feet attached to the
bottom of the rectangular frame.

Setup Instructions
Placing components with sharp or pointed feet directly on the isolation base may
cause nicks, scratches, or gouges in the surface. Use of a protective barrier
between any metal-like feet or sharp objects will prevent damage to the isolation
base surface. Protection from sharp objects is recommended to prevent scratches
and maintain the original beauty of the isolation base.
R3X Isolation Bases are produced with different HRS footer designs to optimize
the performance of specific components. The type of footer the isolation base was
originally configured with is identified on the packaging label on the outside of
the box of each base. The footer designation is also identified by a color-coded
dot located on the back edge of the frame. HRS isolation bases have a unique
ability to change at any time to optimize performance for a different component
or different environment. If you change the feet of the isolation base, we
recommend you also change the color-coded dot on the back of the isolation base
so it is easy to identify what performance setting the base is currently configured
in your system.
The HRS G7 footer does not have any load range limit. You can place any
component on an R3X Isolation Base configured with G7 feet. An R3X Isolation
Base with G7 feet is not sensitive to component weight or weight distribution.
HRS Broadband Isolation (SF2 and SF3) and HRS Subsonic Broadband Isolation
(LF2 and LF3) footers are made in various load ranges to optimize performance
for different component weights. When using the SF and LF footers please verify
that the component that will be placed on the isolation base is within the rated
load range for SF footer or is the specific component model number for LF
footers.
If the SF or LF footers of the R3X Isolation Base are overloaded, the HRS
isolators will hit a protective stop and significantly reduce the product
performance. If your isolation base has SF or LF feet (pictured below), you can
check to see if the isolation base is overloaded by testing for compliance between
the isolation base frame and the feet at each corner. With the component loaded
on the isolation base, check each corner individually by pressing down firmly on
each corner. An isolation base with SF and LF feet should be compliant at each
corner location and not feel rigid. If there is displacement at each corner then the
isolation base is working as designed. If there is no compliance at one or more
corners then the load range should be changed by HRS to the proper load range.
HRS can modify the R3X Isolation Base load range as many times as needed for a
fraction of the original purchase price. Overloading the isolation base for an
extended period of time may reduce its service life and voids the warranty.
The HRS G7 feet (pictured below) will not have any compliance and so they
should not react when you press down on the corner of the base. Instead, check
that all four feet are in direct intimate contact with the surface the isolation base is

resting on by pressing down firmly at each corner and observing if the isolation
base rocks up and down. If any rocking motion occurs, adjust the G7 foot at the
rocking corner by turning it counter-clockwise (as viewed from below base
frame) 1/8 of a rotation at a time until it no longer rocks under pressure. Always
maintain at least three full rotations of thread engagement on each G7 foot.
Optimal performance will be achieved when at least three G7 footers are threaded
fully into the frame and only one foot is adjusted to prevent rocking. The G7 feet
are not designed to level the base frame. Leveling of the R3X Isolation Base is
done by adjusting the HRS frame or other supporting structure.

A majority of source components have a center of gravity that is approximately
near the geometric center of the component. However, some amplifiers and
source components can have significant variation in weight distribution that is
dependent on the design layout of the heavier objects within the component.
The HRS G7 feet are not sensitive to component weight or weight distribution.
You can use the HRS G7 feet with any component weight and any weight
distribution. For the SF/LF feet the ideal isolation base setup is to have the center
of gravity of the component in the geometric center of the isolation base. This will
result in even loading of the SF/LF feet. This can be achieved by estimating the
center of gravity of your component and placing it in the geometric center of the
isolation base. Even loading of the SF/LF feet can also be achieved by moving the
component until the isolation base is level.

Component and Isolation Base
If you have a component that does not allow you to locate the center of gravity
near the geometric center of the isolation base with SF/LF feet, you can utilize a
custom combination of isolation feet to accommodate a significant variation in
isolator loading. Please consult with your authorized HRS retailer or HRS directly
if you have questions regarding proper loading of your R3X Isolation Base.
Custom HRS Isolation Bases built for a specific component model have already
been set up for that specific component weight distribution. If the component is
centered on the custom isolation base and the HRS logo is in the right front corner
then the loading of a custom base model is correct.

Specifications
The following specifications are based on your R3X Isolation Base part number
which is marked on the outside of the original factory box. The part number is
composed of the following information sequence:
Series - Model Number – Foot Type (Load Range) - Base Color
The load range can also be identified by the color of the sticker located on the
back of the isolation base frame. Just cross reference the color of the sticker to the
table on the next page that corresponds to your base’s model number. The
isolators are also marked with colored dots that should match the colored sticker
on the back of the frame. Bases with custom load ranges have no colored sticker,
but their isolators are marked.
The recommended load range is the range of component weight that will yield
optimal performance. If you have less than recommended load you will still likely
obtain very good results based on HRS technology. Placing more than 10% over
the maximum recommended load may result in a significant decrease in isolation
base performance because there is a safety stop mechanism that will engage to
prevent damage to the isolation base. When the safety mechanism is engaged the
performance is decreased significantly until the isolation base is returned to
within its rated load range.

Care and Maintenance
The R3X Isolation Base is a very low maintenance item that will provide many
years of trouble free performance by applying these basic care instructions.
Clean the surfaces of the R3X using a lint-free soft (non-abrasive) cloth. If needed
use a cloth lightly damped with water. Do not use any solvents and do not use any
abrasive cleaners or abrasive materials on any part of the isolation base.
Do not spray, soak, or submerge the isolation base in water or any cleaning
solutions. The isolation base is an assembly of many different parts and materials.
Submerging the isolation base will cause permanent damage to the assembly.
Do not wash the interior flex element of the isolation feet even if you see a
coating or white substance on the surface of the flex element. This coating is
intentional and is put in the flex element to protect the custom isolation material
from the environment.
Warnings!
Do not place objects with sharp or pointed feet directly on the isolation base.
Do not immerse in water or spray with water or any other liquids.
Do not use abrasive cleaners or abrasive sponges.
Do not wash the base or isolation feet with any solvent based cleaning solutions.
Do not wash the interior flex element of the isolation feet even if you see a
coating or white substance on the surface of the flex element.
