M3X2 ISOLATION BASE
The Foundation Of Great System Performance

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 and Nimbus
products. While the M3X2 Isolation Base works to significantly reduce
structural-borne vibration, the HRS Damping Plates and Nimbus products
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.
All HRS products are manufactured in the US by highly skilled craftsmen using
superior techniques, exotic finishes, and proprietary materials. HRS is dedicated
to producing the finest audio products in the world. To accomplish that, all
products advance through a series of intense inspection and approval protocol.
All items are inspected 100% to verify the assembly fits are up to our exacting
standards. This rigorous protocol, combined with precision design, results in a
product that is a pleasure to install, use, change, or expand at anytime. From all
of us here at HRS, we truly hope you enjoy our product.

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 instruction 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 for various load ranges to optimize
performance. Please verify that the component that will be placed on the
isolation base is within the rated load. You can determine the load range of your
isolation base by the color code in the isolation base part number. The isolation
base part number is located on the product identification tag fixed to the bottom
of the isolation base. See the specification section of this manual to determine the
rated load range of your isolation base. If the M3X2 Isolation Base is overloaded
the custom HRS isolators will bottom out and significantly reduce the product
performance. You can check to see if the isolation base is overloaded by checking
for compliance between the isolation base frame and the four small feet. With the
component loaded on the isolation base, check each corner individually by
pressing on each corner. The isolation base should be compliant at each location
and not rigid. If there is any displacement prior to bottoming then the isolation
base is working fine. If there is no compliance at all then the load range should
be changed by HRS to the proper 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.
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 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
isolation 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 isolation 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, 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.

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 - 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.
