S3 ISOLATION BASE
A Low Noise Floor Is Fundamental

2
Introduction
Thank you for purchasing the Harmonic Resolution Systems S3 Isolation Base.
When used properly, it will give you many years of superior musical or video signal
reproduction.
The S3 Isolation Base is a highly innovative design that eliminates noise, revealing
a new level of musical performance. Decades of engineering experience, custom
material development, and listening tests are incorporated into the design of the S3
Isolation Base. The performance of the S3 Isolation Base will enable your
audio/video source and amplification components to achieve a very high level of
performance.
The S3 Isolation Base is an excellent match with HRS Damping Plates, Nimbus
products, Vortex, and Helix products. While the S3 Isolation Base works to
significantly reduce structure-borne vibration, the HRS Damping Plates, Nimbus,
Vortex, and Helix products significantly reduce the harmful effects of airborne
vibration and structural resonance on your components.
Please read this manual completely for setup and product care instructions prior to
use of your S3 Isolation Base. Proper care of your S3 Isolation Base will ensure
optimum performance and an aesthetically pleasing appearance.

Safety Instructions
IMPORTANT WARNINGS!
Do not place any tall objects on the HRS Isolation Base. A tall object is any object
with a height that is greater than the length of the HRS 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 HRS 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 HRS Isolation Base should always be done by means of the
outer rectangular frame. Do not lift the HRS 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 HRS Isolation Base
may cause nicks, scratches, or gouges in the surface. The use of a protective barrier
between any metal-like feet or sharp objects will prevent damage to the HRS
Isolation Base surface. Protection from sharp objects as described above is
recommended to prevent scratches and maintain the original beauty of the HRS
Isolation Base.
S3 Isolation Bases are produced with different HRS Footer designs to optimize the
performance of specific components. The type of footer the HRS Isolation Base
was originally configured with is identified on a label on the outside of its original
packaging. 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 be changed
at any time to optimize performance for a different component or different
environment. If you change the feet of the HRS Isolation Base, we recommend you
also change the color-coded dot on the back of the HRS Isolation Base so it is easy
to identify what performance setting the base is currently configured to.
The HRS G7 Bi-Directional Noise Reduction Footer does not have any load range
limit. You can place any component on an S3 Isolation Base configured with G7
Feet. An S3 Isolation Base with G7 Feet is not sensitive to component weight or
weight distribution. HRS Broadband Isolation Feet (SF2 and SF3) and HRS Low
Frequency Feet (LF2 and LF3) 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 which will be placed on the HRS 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 S3 Isolation Base are overloaded, the HRS isolators
will hit a protective stop and significantly reduce the product performance. If your
HRS Isolation Base has SF or LF Feet (pictured on the next page), you can check
to see if the HRS Isolation Base is overloaded by testing for compliance between
the HRS Isolation Base frame and the feet at each corner. With the component
loaded on the HRS Isolation Base, check each corner individually by pressing down
firmly on each corner. An HRS 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 HRS 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 HRS S3 Isolation Base load range as
many times as needed for a fraction of the original purchase price. Overloading the
HRS 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 HRS Isolation Base is resting
on by pressing down firmly at each corner and observing if the HRS 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 HRS Isolation Base. Leveling of the S3 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 HRS Isolation Base setup is to have the
center of gravity of the component in the geometric center of the HRS Isolation
Base. This will result in even loading of the SF/LF Feet. Achieve this by estimating
the center of gravity of the component and placing it at the geometric center of the
HRS Isolation Base. Even loading of the SF/LF Feet can also be achieved by
moving the component until the HRS Isolation Base is level.

Component and HRS Isolation Base
If you have a component that does not allow you to locate the center of gravity near
the geometric center of the HRS Isolation Base with SF/LF Feet, you can utilize a
custom combination of feet to accommodate a significant variation in isolator
loading. Please consult with your authorized HRS dealer or HRS directly if you
have questions regarding proper loading of your S3 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 HRS 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 HRS S3 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 HRS 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 HRS
Isolation Base performance because there is a safety stop mechanism that will
engage to prevent damage to the HRS Isolation Base. When the safety mechanism
is engaged, the performance is decreased significantly until the HRS Isolation Base
is returned to within its rated load range.

Care and Maintenance
The S3 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 S3 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 HRS Isolation Base.
Do not spray, soak, or submerge the HRS Isolation Base in water or any cleaning
solutions. The HRS Isolation Base is an assembly of many different parts and
materials. Submerging the HRS Isolation Base will cause permanent damage to the
assembly.
Do not wash the interior flex element of the 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 HRS 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 its feet with any solvent-based cleaning solutions.
Do not wash the interior flex element of the feet, even if you see a coating or white
substance on the surface of the flex element.
