Safety Instructions

IMPORTANT WARNINGS! Do not place any tall objects on the top level of the EXR Audio Stand System. 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 EXR Audio Stand System for any reason. The object may become unstable and tip over causing damage to the component, adjacent objects, or injury to people. Never lift or move the EXR Audio Stand System with Isolation Bases installed. You should always move the EXR Audio Stand System to its final location prior to loading Isolation Bases and components. Moving the EXR Audio Stand System with Isolation Bases installed (with or without equipment) can permanently damage the system or cause the Isolation Bases to fall out of the rack, resulting in potential damage or injury. Always take the time to remove all of the equipment and Isolation Bases to relocate the EXR Audio Stand System.

Setup Instructions

• The EXR Audio Stand System is a complete system that can be used with or without HRS Isolation Bases.
• The components required to assemble the system are shipped in one or more boxes.
• The number of boxes depends on the system size.
• Each box containing parts for the system will be marked with the model number starting with EXR.
• All the wrenches required to put the system together are included with the shipment.
• Work Surface – Prior to unpacking any material, locate a very strong and very stable work surface (capable of supporting 250 lb. load) or area on the floor that will give you a very soft scratch resistant work area that is at least three feet by three feet in size.
• The more space you have the better, as it will give you room to move around the system to complete assembly.
• It is important that the area be free of all dirt, screws or small pebbles, and that it is covered with a clean soft protective blanket of same size that will prevent damage to high quality finish on the frame.
• Unpacking Assembly Hardware Remove all the contents from all the boxes marked with the EXR model number.
• Place all the hardware on a table adjacent to your selected work surface and remove all the wrapping material.
• Be careful not to drop or allow the anodized aluminum parts to contact each other as they may scratch each other.
• Do not stack the parts on top of each other once they are removed from the protective packaging material.
• To make assembly easier, group identical parts together in an organized manner.
• Group all the struts by length. This EXR audio stand system will be assembled upside down.
• Depending on what system configuration you have purchased there will be a number of Frame Mounts that have threaded caps already attached.
• Do not try to remove these threaded caps, as they are bonded to the frame.
• These Frame Mounts with threaded caps will be the top of the audio stand system.

Step 1. One EXR Horizontal Support Assembly is designated as the top- level of the audio stand and has threaded EXR Caps bonded into the four EXR Frame Mounts. Place it upside-down on your work surface so the threads of the installed caps face up, and the front face with HRS logo faces away from you (photo 1).
Photo 1 Steps 2-5 describe how to add a second level (and any subsequent levels) to your EXR Audio Stand System. If you are constructing a 1V model EXR (i.e., a singlelevel stand), proceed immediately to step 6. (Note that assembly photos going forward show a two-level audio stand system, but that all written instructions apply to any size stand thanks to the modular design of the EXR.)
Step 2. Place a polymer ring around the threads protruding through each Frame Mount (photo 2). The polymer ring should sit completely flat inside the Frame Mount. Apply a few drops of the provided WD-40 3-in-1 oil to the end of each thread.
Step 3. Identify the four EXR Struts of the correct size for this level of the EXR. Keep in mind that the EXR is being assembled upside-down, and so the first EXR Horizontal Support Assembly is the top level. The struts will provide component spacing equal to 3.5 inches less than their total length (including threads). e.g. Struts that measure 13.5 inches end-to-end will provide 10 inches of spacing. If you will be using HRS Isolation Bases in your EXR, remember that the isolation bases are approximately 3 inches tall when determining your required spacing. Fully thread one strut onto the threaded cap in each EXR Frame Mount (photo 3). Use the provided HRS Grip Pad (photo 4) to tighten each strut between 1/4 and 1/2 rotation past when it contacts the polymer ring.
Step 4. Place a polymer ring around the threads of each strut just as you did for the caps on the top level. Be sure the polymer rings sit fully on the strut as shown in photo 5. The polymer ring should sit on the non-threaded shoulder just below where the thread stops. Apply a few drops of WD-40 3-in-1 oil to the ends of these threads as well.
Step 5. Carefully lift another EXR Horizontal Support Assembly and lower it onto the existing assembly so that the strut threads pass through the Frame Mounts as in photo 6. The Frame Mounts should seat fully onto the threads and rest in full contact with the polymer rings. Photo 6 If your EXR Audio Stand System includes another level, repeat steps 2-5 for the next EXR Horizontal Support Assembly to add it to the stand. Be sure to select the correct size of strut for each level of your stand to provide adequate space for each of your components. If you have added all necessary levels to the EXR, proceed to step 6.
Step 6. Place a polymer ring around the threads protruding through each Frame Mount. The polymer ring should sit completely flat inside the Frame Mount. Apply a few drops of the provided WD-40 3-in-1 oil to the end of each thread.
Step 7. Fully thread an EXR Locking Nut onto the threads protruding through each Frame Mount so the locking nuts fully contact the polymer rings you placed in step 6. Thread the locking nuts on with the narrow end facing down into the Frame Mounts. Apply final torque to the EXR Locking Nuts by using the provided custom nylon wrench to tighten each nut another 1/4 to 1/2 turn after they contact the polymer ring (photo 7). This final torque provides stiffness to the structure to ensure excellent performance for your system.
Step 8. Thread on the EXR Washers just until they contact the locking nuts, and then thread on the EXR Points just until they contact the washers (photo 8). Do not torque the washers or points tightly.
Step 9. Assembly of the EXR Audio Stand System is now complete. Carefully lift and flip the EXR upright and move it the desired final location for use in your system. Depending on the size of your audio stand this may require multiple people. Make sure to orient the audio stand system so that the front face with the HRS logo(s) faces forward. The stand points should be placed directly on carpeted floors. Place them on HRS Floor Protectors (sold separately) instead if your system is located on wood flooring or another surface you wish to guard against scratching. Please contact your dealer or HRS if you require HRS Floor Protectors.

Leveling the EXR Audio Stand
The EXR Audio Stand System is now ready to be leveled. Place the provided level on the top EXR Horizontal Support Assembly and apply gentle pressure against each side of the stand to see if it rocks back and forth. If the stand does rock back and forth and/or does not sit level, thread out the point(s) that must be extended to level the stand 1/4 turn at a time until the stand is level with all four points in contact with the ground. Do not thread out the point(s) more than five full rotations. Each point must have three full rotations of engagement with the thread for proper performance and strength. If more adjustment is required, place a shim under the point(s) so that the additional travel is achieved without violating the three full thread minimum engagement requirement. Once the system is level, hold the extended point(s) with one hand and thread the washer down with your other hand back against the top of the point. Gently torque all four washers against the tops of the points with the HRS Grip Pad. This will lock the points into place and prevent any motion out of the threaded connection. The result should be a very stable, firm, and level structure.

Installing HRS Isolation Bases into the EXR Frame (optional)
If your system includes HRS Isolation Bases, unpack each base that will be installed in the EXR Audio Stand System. Make sure to read and follow all of the instructions in the isolation base manual prior to installing bases into the EXR. Also verify that the EXR size matches the isolation base size.
Note the load range of each isolation base to determine which component of your system each base is matched to. Matching the isolation base to the proper component weight will ensure optimum performance. Load ranges can be changed for a nominal factory fee, so if you do not have the correct load range for a component, please contact Harmonic Resolution Systems or your local certified retail location to have this corrected.
Load the isolation bases into the EXR Audio Stand System with the HRS logo facing the front of the system. Carefully pass each isolation base between the front struts of the stand, and have another person support the rear edge while you both gently lower the base to contact the shelf surface. Sliding isolation base feet along the shelf surfaces may scratch them. Make sure that the outside edges of each isolation base line up with the outside edges of the EXR Horizontal Support Assembly.

Loading Components into the EXR Audio Stand System
Carefully load each component from the front of the EXR Audio Stand. Be careful not to hit any part of the shelves or isolation bases. If you are utilizing isolation bases in your EXR, make sure that none of the isolation bases are overloaded. By placing one or two fingers on the bottom of the EXR Horizontal Support Assembly, and your thumb on the top of the isolation base, you should be able to move the top of the isolation base slightly (at all four corners) by squeezing your fingers together. If there is no compliance, verify the load range of the isolation base is correctly matched with the component. Please consult with your authorized Harmonic Resolution Systems dealer or contact Harmonic Resolution Systems if you need assistance. The isolation base load range can be easily modified by sending it to Harmonic Resolution Systems or an authorized dealer to have the primary isolation stage rebuilt. The maximum load capacity of each shelf of the EXR Audio Stand System is 250 pounds (113 kg). Never load more than 250 pounds onto a single shelf of the EXR, and never exceed a total load of 1000 pounds (453 kg) for the full system. Modifying or expanding your EXR Audio Stand System – Please contact HRS or your local certified dealer if you would like to modify your EXR. Thanks to the modular design of the EXR, expanding your system by adding shelves or even splitting into multiple stands can be done in your own home with parts available from HRS. Simply remove all components from your EXR, and turn it upside-down on a work surface prepared the same as for the original assembly process. Remove the EXR points and washers by hand, and use the custom nylon wrench to remove the EXR locking nuts. After that, EXR Horizontal Support Assemblies and struts can be added, removed, and interchanged freely. Make sure to install and tighten all parts according to the original assembly instructions in this manual.
