M3X2 ISOLATION BASE
A Low Noise Floor Is Fundamental

2
Introduction
Thank you for purchasing the Harmonic Resolution Systems M3X2 Isolation Base.
The M3X2 was derived from our M3 series isolation bases and represents the latest
in HRS technology and innovation. When used properly, it will give you many
years of superior musical or video signal reproduction.
The M3X2 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 M3X2 Isolation Base. The performance of the
M3X2 Isolation Base will enable your audio/video source and amplification
components to achieve peak performance.
The M3X2 Isolation Base is a perfect match for HRS Damping Plates, Nimbus
products, Vortex, and Helix. While the M3X2 Isolation Base works to significantly
reduce structural-borne vibration, the HRS Damping Plates, Nimbus products,
Vortex products, and Helix significantly reduces the harmful effects of air-borne
vibration and structural resonance on your components.
Please read this manual completely prior to use of your M3X2 Isolation Base for
set up and product care instructions. Proper care of your M3X2 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 depth 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 inner plate or the external
feet attached to the bottom of the rectangular frame. Always lift or move the
isolation base with the inner plate facing up and the external support feet facing
down (same orientation as when used to support your component). The inner plate
is bonded to the outer frame. Following these handling instructions will prevent
damage to the unit and will ensure the inner plate does not accidentally come out
of the outer frame when moving the isolation base.

Setup Instructions
Placing components with sharp or pointed feet directly on the isolation base may
cause nicks, scratches or gouges in the surface. Use a protective barrier between
sharp objects and the base surface if you desire. The M3X2 Isolation Base is very
effective at reducing vibration and does not require the use of cones and other sharp
objects. Cones can be used with the isolation base and do not degrade the isolation
base performance. Protection from sharp objects as described above is
recommended to prevent scratches and maintain the original beauty of the isolation
base.
M3X2 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 M3X2 Isolation Base configured with G7 feet. An M3X2
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 M3X2 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
M3X2 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 M3X2 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 M3X2 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 M3X2 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 M3X2 Isolation Base is a very low maintenance item that will provide many
years of trouble free performance by applying these basic care instructions.
The top of the M3X2 Isolation Base contains a natural granite surface. Clean the
granite surface using a lint-free soft (non-abrasive) cloth. Use a damp cloth with
mild soap if required. Do not use abrasive cleaners on any part of the isolation base.
To keep the granite surface in excellent condition HRS recommends Stone Tech
Professional Revitalizer â as instructed on the container. Contact your local granite
supply facility or HRS to purchase this or equivalent care product.
Do not spray, soak, or submerge the isolation base in water or cleaning solutions.
The isolation base is an assembly of many different parts and materials.
Submerging the isolation base may cause damage to the assembly.
Clean the metallic parts of the isolation base, feet and frame, using a lint-free soft
(non-abrasive) cloth. Use a damp cloth with mild soap if required. Do not use
abrasive cleaners or solvents to clean the isolation base. Abrasive cleaners or cloths
of any type may damage the finish of your isolation base. Solvents can attack and
damage some of the materials in the isolation base and should never be used.
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.
