Safety Instructions
IMPORTANT WARNINGS!
Do not place any tall objects on the top shelf of the SXRC 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 SXRC 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 SXRC Audio Stand with the shelves (Isolation Bases)
installed. You should always move the SXRC Audio Stand frame to its final
location prior to loading shelves and components. Moving the SXRC 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 SXRC Audio Stand.
Do not lift the M3X Isolation Base by the inner plate or any Isolation Base by 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.

Setup Instructions
The SXRC 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 SXRC. 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 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 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 SXRC 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 Struts 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 SXRC 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 Members will already be attached. If your SXRC was
partially assembled, complete assembly by skipping Steps 1-2 and referring to the
instructions starting at Step 3.

Step 1. Obtain a Support Brace with threaded studs and place it on the work
surface with threads facing up. Obtain a Cross Member and place it upside-down
on the work surface. Slide one end of the Cross Member into one of the slots on
the Support Brace. The holes of the Support Brace should line up with the
threaded holes of the Cross Member. Slide a second Cross Member into the other
slot in the same way (Picture 1). Make sure the HRS Logos on the two Cross
Members face the same direction.
Picture 1
Step 2. Using the 5/32” ratchet wrench supplied with unit, attach the Cross
Members to the Support Brace with the 1/4” - 20 x 3/4” flat head cap screws
supplied with the unit (Picture 2). Before tightening screws fully be sure that the
Cross Member and Support Brace are completely perpendicular to each other
(minor adjustments can be made prior to tightening the bolts). Tighten the screws
until the handle of the T-wrench twists about 1/16 to 1/8 of a rotation without
turning the screws. This will give you proper torque on the assembly.
Attach a second Support Brace to the other end of the Cross Members in the same
way.

Note: Be very careful not to cross-thread the threaded struts or fasteners. All
parts should thread in easily. If one does not, back it out and start it in again.
Never force a threaded connection. If a part does not thread on easily, contact
HRS or your local retail facility for assistance. Apply torque only when instructed
and only after all the fasteners at each step are in place.
Step 3. Slide a polymer ring over each of the threaded studs (Picture 3). Push
down until the polymer ring is seated in the groove on the Support Brace.
Picture 3
Step 4. Apply 4-5 drops of the 3-in-1 oil supplied with the unit to the top few
threads on each stud (Picture 4).

If assembling an SXRC-1V (single-level stand or amp stand) go to Step 10. If not,
continue with next step.
Step 5. Screw struts onto the threaded studs (Picture 5). If you have a stand
with multiple strut sizes, keep in mind that you are assembling the stand upside-
down. The first struts to be installed will be between the top and second shelf
when the stand is completed.
Picture 5
Note: Shelf spacing is approximately 3” less than the strut length. Verify that 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 onto the threaded studs will begin to get more
difficult when they come in contact with the polymer rings. Use the HRS Grip
Pad to torque all of the SXR Struts for this layer (Picture 6). The strut has proper
torque when it is approximately ¼to ½turn past snug. It is important to apply
proper torque to the struts to achieve proper frame stiffness and performance.
Picture 6

Step 7.Place a polymer ring over the threaded end of each strut on this layer. Be
sure the polymer ring is seated fully as it was in Step 4. The polymer ring should
sit on the shoulder just below the thread (Picture 7).
Picture 7
Step 8.If it is required for the unit you are assembling, refer to steps 1 and 2 to
build another Support/Cross Member subassembly. Ignore any reference to the
threaded studs that the first set of Support Braces had. Only the top layer of braces
will have those studs.
In step 2, finger-tighten the screws attaching the Cross Members to the Support
Brace rather than using the T-wrench. They will be fully tightened later on. If
your SXRC came with brace subassemblies preassembled, the 1/4” - 20 x 3/4” flat
head cap screws must be loosened 1/4 turn before proceeding to Step 9.
Step 9.Carefully place the Support/Cross Member subassembly onto the struts
of the SXRC by placing each strut through one hole of the Support Braces. Make
sure the HRS logos on all of the Cross Members face the same direction. Also
make sure that each strut is properly seated into a countersunk hole of the Support
Brace.
Step 10. Fully tighten the screws connecting the Cross Members to the Support
Braces. Before tightening screws fully be sure that the Cross Members and
Support Brace are completely perpendicular to each other. Use the ratchet wrench
to tighten the screws about 1/16 to 1/8 of a rotation past snug. This will give you
proper torque on the assembly. After all the screws are tightened, check one more
time to make sure the Struts are still sitting in the counter bores on the backside of
the Support Brace.
Step 11. Add a polymer ring and oil to each strut as in Steps 3 and 4.

9
If your SXRC requires another layer, repeat Steps 5-11. Note that 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 1/4 to 1/2 turn
past snug).
Step 12. Make sure there is a Polymer Ring over each of the exposed threads,
and screw a Locking Nut onto each one. Tighten the Locking Nuts by hand at
first, then torque them using the custom nylon wrench another ¼turn past snug
(Picture 8).
Picture 8
Step 13. Screw Washers onto the threads over the Locking Nuts (Picture 9).
Screw the Washers down only until they contact the Locking Nut. Do not put a
large torque on the Washers.
Picture 9

10
Step 14.Screw the Stand Points onto the threads (Picture 10). As with the
washers, tighten the Stand Points by hand until they contact the Washers. Do not
over-torque the Stand Points.
Picture 10
Step 15. At this point the SXRC Frame is completely assembled. Picture 11
shows a completed SXRC-1921-2V. Flip the SXRC Frame upright. Move the
frame to the exact final location for use in your system. The front of the frame is
the side from which the HRS logos can be read right side up.
Picture 11

11
You are now ready to level the SXRC frame. Place a level on one of the top Cross
Members. Loosen the Stand Points as required so that they all contact the floor.
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. Now bring down the rest of the Stand Points so that they are in
contact with the floor.
After the stand frame is level, hold the Stand Points with one hand and screw the
Washer with your other hand down until it touches the top of the Stand Point.
Torque the Washer against the Stand Point as much as possible with your hands.
You can use the HRS Grip Pad 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.

12
Isolation Base Installation into SXRC Frame - Uncrate each of the isolation
bases. Make sure you read and follow all of the instructions in the isolation base
manual prior to installing into the SXRC Audio Stand frame. You will want to
verify that the frame size matches the isolation base size. The SXRC-1921-2 uses
the 1921-2 isolation bases. The SXRC-2029-2 uses the 2029-2 isolation bases,
and so on.
Match the load range of each isolation base with the component weight. Matching
the isolation base to the proper component weight will ensure 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 SXRC frame with the HRS logo facing the front
of the rack system. Picture 12 shows this in an SXR-3V system. Be sure that the
isolation base (shelf) feet are located securely in the pocket of the SXRC 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 may
not have the proper size isolation base or frame.

Loading Components into SXRC Frame - Carefully load each component into
the SXRC Audio Stand. Be careful not to hit the front edge of the isolation base
as this may 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
corner of the isolation base, you should be able to move the top of the isolation
base slightly when you squeeze your fingers 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 each isolation
base is identified by the colored sticker on the back of the base (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 the base to Harmonic Resolution Systems or an authorized dealer to have
the primary isolation stage rebuilt.

Care and Maintenance
The SXRC 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 SXRC 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 SXRC.
Please follow the care instructions in the isolation base manual to clean and care
for the shelves (isolation bases) of the SXRC 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 SXRC 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
SXRC 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 SXRC 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.
