HRS E1 Isolation Base User Guide
Introduction
Thank you for purchasing the Harmonic Resolution Systems E1 Isolation Base.
When used properly, it will give you many years of superior musical or video
signal reproduction.
The E1 Isolation Base significantly reduces the negative impact of structure borne vibration on your audio or video component performance. Many decades of engineering experience, custom material development, and listening tests are incorporated into the design of the E1 Isolation Base. The performance of the E1Isolation Base will enable your audio/video source and amplification components to achieve a very high level of performance.
The E1 Isolation Base is an excellent match with HRS Damping Plates, Nimbus, Vortex, and Helix. While the E1 Isolation Base works to significantly reduce structure-borne vibration, the HRS Damping Plates, Nimbus products, 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 E1 Isolation Base for setup and product care instructions. Proper care of your E1 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.
E1 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 anytime 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 E1 Isolation Base configured with G7 feet. An E1 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 E1 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 E1 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 E1 Isolation Base is done by adjusting
the HRS frame or other supporting structure.
Note: The listed heights above are from bottom to top of outer metal housing only (not to the top of isolators, shims, or threads)
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 E1 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 E1 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 the box and product tag are marked with specific custom model number information and each isolators are marked in the center of foot.
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 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 adjusted to the proper rated load range.

Care and Maintenance
The E1 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 E1 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.
