SXR AUDIO STAND
The Foundation of Great System Performance

Introduction
Thank you for purchasing the Harmonic Resolution Systems SXR Audio Stand.
When used properly, it will give you many years of superior musical or video
signal reproduction.
The SXR Audio Stand significantly reduces the negative impact of structure-borne
noise on your audio or video component performance. Decades of engineering
experience, custom material development, and listening tests are incorporated
into the design of the SXR Audio Stand. This high performance product from
Harmonic Resolution Systems, Inc. will enable your audio/video source and
amplification components to achieve high levels of performance.
The SXR Audio Stand, which includes the HRS Isolation Base as the primary shelf
system, is a perfect match for the HRS Damping Plates and Nimbus Products.
While the SXR Audio Stand and Isolation Bases work to significantly reduce
structure-borne noise, the HRS Damping Plates and Nimbus Products
significantly reduce the harmful effects of air-borne noise and structural
resonance on your components.
Please read this manual completely prior to assembly and use of your SXR Audio
Stand. It contains instructions necessary for proper assembly, use, and care of
this system. Proper care of your SXR Audio Stand will ensure optimum
performance and an aesthetically appealing system.

Safety Instructions
IMPORTANT WARNINGS!
Do not place any tall objects on the top shelf of the SXR Audio Stand. 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 SXR Audio Stand 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 SXR Audio Stand with the shelves (Isolation Bases)
installed. You should always move the SXR Audio Stand frame to its final
location prior to loading shelves and components. Moving the SXR Audio Stand
frame with the isolation bases installed (with or without equipment) can
permanently damage the frame system or cause the shelves to fall out of the rack
resulting in potential damage or injury. Always take the time to remove all of the
equipment and shelves to relocate the SXR Audio Stand.
Do not lift the Isolation Base (shelf) by the inner plate (M3 model) 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). Always
follow these handling instructions to prevent personal injury or damage to the
unit.

Set-Up Instructions
The SXR Audio Stand consists of a frame structure and the isolation bases that
support each component. The components required to assemble the frame are
shipped in one or more boxes. The number of boxes depends on the system size.
Each box containing parts for the frame will be marked with the model number
starting with SXR. All the wrenches required to put the frame 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 three feet by three
feet in size. The more space you have the better, as it will give you room to move
around the frame 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 SXR 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 the surface. 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. Make sure all tubes are
matched for proper (same) length.
This audio stand will be assembled upside down. Depending on what frame
configuration you have purchased there will be a number of Support Braces that
have threaded studs already attached. Do not try to remove these threaded studs
as they are attached to the frame. These Support Braces with threads will be the
top of the audio stand.
Note:
Depending on how your SXR audio stand frame was shipped it may arrive
partially assembled. This means Steps 1 and 2 would have been completed so the
Support Braces and Cross Braces will already be attached. If your SXR was
partially assembled, complete assembly by skipping Steps 1 and 2 and referring to
the instructions at Step 3.

Step 1. Obtain one of the Support Braces with threaded studs. Place it upside
down on the work surface with threads facing up (see photo 1). Obtain a Cross
Brace and flip this over as well as shown in Photo 1 below. Slide one of the ends
of the Cross Brace into the area below the countersunk holes on the Support
Brace. The countersunk holes of the Support Brace should line up with the
threaded holes of the Cross Brace.
Step 2. Using the 5/32” T- wrench or ratchet wrench (supplied with stand)
attach the Cross Brace to the Support Brace with the 1/4” - 20 x 3/4” flat head
cap screws (also supplied with the unit). Before tightening screw fully be sure
that the Cross Brace and Support Brace are completely perpendicular to each
other as shown in Photo 2. Tighten screws (shown in Photo 3) until the screws
stop turning and the top of wrench handle twists an additional 1/16 and 1/8 of a
rotation relative to the bolt. This will give you proper torque on the assembly.
Repeat steps 1 and 2 for the opposite side of the Cross Brace with again checking
that the two parts are perpendicular to each other (minor adjustments can be
made prior to torque of the bolts).
Note: If assembling a double or triple wide SXR the Center Brace will be
installed to the other side of the Cross Brace.
Photo 1

Note: Be very careful not to cross-thread the threaded struts or fasteners. They
should thread in very easily. If it does not, back it out and start it in again (repeat
as necessary). Never force a threaded connection. If it does not thread on easily
then there is something wrong and you should contact HRS or your local retail
facility for assistance. Apply proper torque when instructed and after all the
fasteners at each step are in place.

Step 3. Slide a polymer ring over each of the threaded studs on the Support
Brace as shown in Photo 4. Push down until the polymer ring is seated in the
groove on the Support Brace.
Step 4. Apply 4-5 drops of the 3-in-1 oil to the top few threads of each of the six
threaded studs as shown in Photo 5.
If assembling a SXR-1V (one high stand or amp stand) go to Step 10. If not
continue with next step.

Photo 5

Step 5.By hand screw the struts onto the threaded studs as shown in Photo 6. If
you have a stand with different size struts keep in mind that you are building the
stand upside down. The struts you are installing now are the struts that will
become the struts between the top and second shelf when the stand is completed.
Note: Shelf spacing is approximately 3” less than the strut length. Verify you
have the correct strut length required for your system. HRS offers a variety of
strut lengths so consult your dealer if you are not certain you have the correct
parts for your desired spacing.
Step 6. Screwing the struts (of same length) onto the threaded studs will begin
to get more difficult when they come in contact with the polymer rings. Use the
HRS Grip Pad (Photo 7) to torque all of the SXR Struts for this layer. Wrap the
HRS Grip Pad on the SXR Strut as shown in Photo 8. Using your hand on the
HRS Grip Pad to fully torque each strut as shown in Photo 9.. The strut has
proper torque when it is approximately !to "turn (approx 90 degrees or more)
after the strut is finger (snug) tight. For example Photo 9 below shows a strut
being tightened by rotating the strut clockwise using the HRS Grip Pad.
Note: it is important to get proper torque on struts to achieve proper frame
stiffness and performance.
Photo 6

Step 7. After proper torque of each strut is complete, add a polymer ring over
the threaded end of each strut. Be sure the polymer ring is seated fully on the strut
as shown in Photo 10 (the polymer ring should sit on the non-threaded shoulder
just below where the thread stops).

Photo 9

Note:
If your SXR came partially assembled please make sure that in Step 8 the 1/4” -
20 x 3/4” flat head cap screws must be loosened 1/4 turn before proceeding to
Step 9.
Step 8. Refer to steps 1 and 2 to build another Support/Cross Brace
subassembly as shown in Photo 11. However this time each screw should be
finger tight and then loosen by turning the T-wrench or ratchet wrench 1/4 turn
counterclockwise.
Photo 10
Photo 11

Step 9. Carefully place the Support/Cross Brace subassembly onto the struts of
the SXR by placing each strut through the holes of the Support Braces as shown
in Photo 12. Make sure the HRS logo of the Support/Cross Brace subassembly is
located on the same side as first Cross Brace. Make sure that each strut is
properly seated into each countersunk hole of the Support Brace.
At this point the screws connecting the Cross Brace sub assembly should be fully
tightened. Before tightening screw fully be sure that the Cross Brace and Support
Brace are completely perpendicular to each other as shown in Photo 2. Tighten
screws (shown in Photo 3) until the screws stop turning and the top of T-Wrench
handle twists an additional 1/16 to 1/8 of a rotation relative to the bolt. This will
give you proper torque on the assembly. Repeat steps 1 and 2 for the opposite
side of the Cross Brace with again checking that the two parts are perpendicular
to each other (minor adjustments can be made prior to torque of the bolts). After
the 8 bolts are tightened check one more time to make sure the Struts are still
sitting into the counter bores on the backside of the Support Brace.
As done in Step 3 add a polymer ring to each of the threaded ends of the struts
(see Photo 13) Make sure the Polymer Ring sits into the counter bore of the
Support Brace.
Photo 12

Photo 13
As done in Step 4 - add 3-4 drop of oil to each of the threads of the struts.
If your SXR requires another layer to be added repeat Steps 5 to 9. Note when
building the additional layers you should torque the struts in a sequence and then
through the same sequence again until each strut is tight (approximately 1/8 to
1/2 turn past snug to be fully torque).
Step 10. After placing the Polymer Ring over each of the threaded struts.
Screw a Locking Nut onto each of the struts making sure that the end of the
Locking Nut having the smaller diameter is placed on first as shown In Photo 14.
Photo 14

Step 11. When the Locking Nut meets the polymer ring and begins to become
hard to tighten use the custom nylon wrench shown in photo 15 to tighten the
Locking Nut. The Locking Nut will require about 1 full turn after the Locking Nut
is hand tight to achieve desired torque.
Note: it is important to get proper torque on each Strut and the Locking Nuts to
achieve proper frame stiffness and performance.
Step 12. Screw the Washer onto the threads of the struts completely as shown
in Photo 16. Screw all the way down until the Washer comes in contact with the
Locking Nut. Light hand tight is fine. Do not put a large torque on Washer.
Photo 15
Photo 16

Step 13. Screw the Stand Points onto the threads of the struts completely as
shown in Photo 17. Again, just thread on completely until Stand Point is in
contact with Washer but do not over torque.
Step 14. At this point the SXR Frame is completely assembled. Flip the SXR
Frame upright as shown in Photo 18. Move the frame to the exact final location
for use in your system. Make sure the front of the frame is the side with the HRS
logo on the Cross Brace facing into the room. You are now ready to level the
SXR frame. Place a level on the top Cross Brace. Rotate the Stand Point counter
clock wise (clock wise if viewed from the top of the stand) as required to level the
stand and make it stable (contact with floor at all four locations). Make sure you
do not rotate the Stand Points out more than 4-5 complete rotations. The Stand
Points must have 3 complete rotations of engagement remaining with the
threaded strut for proper performance and strength. If more adjustment is
required use a shim under the Stand Points so that the additional travel is
achieved without violating the 3 full thread minimum engagement requirement.
When the stand frame is level, hold the Stand Points with one hand and screw the
Washer with your other hand back into the top of the Stand Point and torque as
much as possible with your hands. You can use the Magic Grip if you need to get
additional torque. This will lock the Stand Points into place and take any motion
out of threaded connection. The result should be a very stable, firm, and level
frame structure.

Isolation Base Installation into SXR Frame - Uncrate each of the isolation bases
if not already complete. Make sure you read and follow all of the instructions in
the isolation base manual prior to installing into the SXR Audio Stand frame. You
will want to verify that the frame size matches the isolation base size. The SXR-
1921 uses the 1921 isolation bases. The SXR-1719 uses the 1719 isolation bases.
Match the load range of each isolation base with the component weight.
Matching the isolation base to the proper component weight will insure optimum
performance. The load range 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 arrange to have this
corrected.
Load the Isolation Bases into the SXR Frame (see Photo 19 and 20), with the HRS
logo facing the front of the rack system. Be sure that the isolation base (shelf)
foot is located securely in the pocket of the SXR Frame Support Brace. This will
automatically occur when the front and back edge of the isolation base is in line
with the front and back face of the frame. If the front and back edges do not line
up with the front and back of the frame structure then, contact Harmonic
Resolution Systems or your certified retail location because you do not have the
proper size isolation base or frame.

the right. Both system shown with M3X Isolation Bases.
Loading Components into SXR Frame - Carefully load each component into the
SXR Audio Stand. Be careful not to hit the front edge of the isolation base
because you will scratch the frame. Once all the components are loaded, you
should check to see that none of the isolation bases are overloaded. By placing
one or two fingers on the bottom of the Support Brace 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) when you squeeze your finger(s) together. If there is
no compliance, remove the isolation base and component to verify the load range
of the isolation base is correctly matched with the component. The load range of
the isolation base is identified as part of the part number on the tag attached to
the bottom (see the isolation base manual for instructions). 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 at any time by sending it to Harmonic Resolution Systems or an
authorized dealer to have the primary isolation stage rebuilt.

Care and Maintenance
The SXR Audio Stand is a very low maintenance item that will provide many years
of trouble-free performance by applying these basic care instructions.
Clean the external surfaces of the SXR Audio Stand frame using a professional
quality ultra soft lint-free micro-fiber cloth available in high quality automotive
stores. Use a lightly water damped cloth if you need to clean dirt from the frame.
Do not use commercial furniture polishes on the SXR.
Please follow the care instructions in the isolation base manual to clean and care
for the shelves (isolation bases) of the SXR Audio Stand. Read and follow the
instructions received with the isolation base to ensure optimum performance and
cosmetic appeal.
Do not spray, soak, or submerge the rack frame or isolation bases in water or
cleaning solutions. The rack system and isolation bases are made from many
different parts and materials. Submerging, spraying, or soaking the rack system
or isolation base will cause permanent damage to the assembly.
Clean the metallic parts of the isolation base and SXR Audio Stand using a lint-
free soft (non-abrasive) cloth. Use a damp cloth with a mild soap or Pledge
Surface Cleaner if required. Do not use abrasive cleaners or solvents to clean the
SXR frame or isolation base, as they will damage the quality of finish. Solvents
and solvent-based cleaners will attack and damage some of the materials used in
the SXR frame and isolation base and should never be used.
Do not wash the interior flex element of the isolation base 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 isolation material from the
environment
Warnings!
Placing ultra sharp pointed feet directly on the isolation base may cause
permanent scratches.
Do not immerse in water or spray with water or any other liquids.
Do not use abrasive cleaners or abrasive sponges.
Do not wash 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.
Be very careful not to cross thread the fasteners when moving the shelf brackets
