MXR AUDIO STAND
The Foundation of Great System Performance
Introduction
Thank you for purchasing the Harmonic Resolution Systems MXR Audio Stand.
When used properly, it will give you many years of superior musical or video
signal reproduction.
The MXR 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 MXR Audio Stand. This reference level
product from Harmonic Resolution Systems, Inc. will enable your audio/video
source and amplification components to achieve peak performance.
The MXR 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 MXR 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 MXR Audio
Stand. It contains instructions necessary for proper assembly, use, and care of
this system. Proper care of your MXR Audio Stand will ensure optimum
performance and an aesthetically appealing.
Safety Instructions
IMPORTANT WARNINGS!
Do not place any tall objects on the top shelf of the MXR 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 MXR 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 MXR Audio Stand with the shelves (M3 Isolation Bases)
installed. You should always move the MXR Audio Stand frame to its final
location prior to loading shelves and components. Moving the MXR Audio Stand
frame with the isolation bases installed (with or without equipment) can
permanently damage the systems adjustable feet 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 MXR Audio Stand.
Do not lift the M3 Isolation Base (shelf) 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). Always follow
these handling instructions to prevent personal injury or damage to the unit.
Set-Up Instructions
The MXR Audio Stand consists of a frame structure and the isolation bases that
support each component. The standard three and four shelf frame structures
come in three boxes. Each box will be marked with the model number starting
with MXR. There are two longer boxes that contain the left and right vertical
panels. The third box contains the panel brace system, the isolation base support
brackets, the adjustable rack feet, screws, and wrenches required to complete the
assembly process. The only tools not provided for assembly are:
1. Adjustable wrench - to lock the feet after leveling the frame
2. Philips Head Screwdriver - for unpacking crates (electric drive
recommended)
3. Level - 24" minimum length or equivalent
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
six 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 (min size 24" x 45") that will prevent damage to the relatively
soft external skin of the vertical panels.
Unpacking Assembly Hardware - Remove all the contents from the smaller
cardboard box containing the hardware required to assemble the frame. Place
them 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.
Unpacking Vertical Panels - Unpack the vertical panel by removing the top
surface of the crate (see Photo 1). This surface will be marked for clarity and you
will need a Philips head screwdriver (manual or electric) to remove the cover.
Photo 1 Photo 2
Lift the panel out of the crate by lifting vertically at each end (see Photo 2). Move
the panel and packing material directly to your damage free work surface. Once
at the work surface, remove and save the two fitted foam end support cushions.
Then open the protective paper covering the panel to expose the unit for
assembly. Saving all the packing material is critical to secure transportation of
the frame in the future. Shipping or moving the panel by any other means may
expose the unit to permanent damage.
Installation of Adjustable Foot System - Unwrap two of the four feet supplied
with the unit. Remove the screw and washer from each of the feet (see Photo 3).
Photo 3
Hands tighten the nut all the way down on each individual foot. Then back the
nut off one half rotation (see Photo 4).
Photo 4
Place the supplied washer on top of the nut and then screw each of the feet into
the threaded inserts on the bottom of the first vertical panel (see Photo 5 & 6).
The feet should be threaded into the insert until the washer/nut come in contact
with the vertical panel threaded insert. (This ensures maximum engagement
between the insert and the foot). Repeat this procedure and install the second foot
to the bottom of the first vertical panel.

Panel Brace Installation - You are now ready to attach the primary brace system
to the panel. There are two braces that hold the two end panels together to form
the primary MXR Frame Structure. There are two rectangular spacers attached
to each brace system when it is shipped that need to be loosened to complete
assembly. Simply take the T-wrench or Allen wrench supplied with the MXR and
loosen (counter clockwise) each of the eight nuts on the brace assembly (see
Photo 7). You do not want to have lots of play in the assembly, you just want to
break the torque on each nut so that the brace can be properly located.
Photo 7
The HRS logo is machined into the center of each brace. Locate the HRS logo on
the brace and orient it so that when the stand is upright on its feet, the logo will
be in correct orientation. There are two steps at each end of the brace sub
assembly that fit precisely over the attachment block on the panel. Slowly lower
the brace assembly onto the block until the steps in the brace contact the block
(see Photo 8 and Photo 9). Attach at least one of the 1/4-20 x 3/4" screws to the
brace assembly (see Photo 10) prior to removing your hand from the assembly to
insure it stays in place. It is very important that the 3/4" long screws are used at
this location to obtain proper thread engagement.
Photo 8 Photo 9
Install all eight 1/4-20 x 3/4" screws to the brace (see Photo 10) until they are
fully engaged but do not torque the screws at this time. You will want to leave
them just loose enough so that there is a very small amount of play to complete
balance of assembly. All the screws for the brace system will be fully tightened at
a later point in the assembly process. If they are tightened at this time, you may
not be able to complete assembly or it will not be level when complete. You will
need to use the Allen wrench (or ratchet wrench) at the location closest to the
frame because the T-wrench will hit the frame preventing screw rotation.
Photo 10
Repeat the panel brace installation procedure for the second brace at the top of
the panel (see Photo 11). Orient the HRS logo so that when the stand is sitting on
its feet the HRS logo will be right side up and in proper orientation. Make sure
that all eight screws are completely installed on each of the two panel blocks (16
screws total) prior to moving to the next assembly process.

Second Panel Assembly - Remove the second panel from the wooden crate and
place it in a separate area to remove all the packing material (see Photo 12 &
13). As noted before, the area and surface used should not pose any threat to the
integrity of the panel surface finish. Please follow the same procedure as noted
for un-wrapping the first panel.
Note: If assembling an MXR frame that consist of more than two panels then
install center panel (isolation base brackets on both sides) at this time as the
second panel
Photo 12 Photo 13
Remove all the foam and packing paper from the second panel. It is important
that two people perform the next step. With one person on each end of the panel,
very carefully and slowly place the attachment block of the second panel into the
top of the brace assembly until it contacts the step on the brace (see Photo 15).
Immediately install at least one 1/4-20 x 3/4" screw into each end on the panel
block and fully engage, but do not tighten the screws (see Photo 16).
Photo 14 Photo 15
Install all sixteen screws, eight at each panel block on the second panel, 1/4-20 x
3/4" screws to the brace (see photo 16) until they are fully engaged, but do not
torque the screws at this time. You will want to leave them just loose enough so
that there is a very small amount of play to complete balance of assembly. All the
screws for the brace system will be fully tightened at a later point in the assembly
process. If they are tightened at this time, you may not be able to complete
assembly or it will not be level when complete. You will need to use the Allen
wrench at the location closest to the frame because the T-wrench will hit the
frame preventing screw rotation.

Squaring the MXR Frame - It is now time to torque all of the screws in the two
brace assemblies. We recommend using a long level to complete this process.
Place the long level across the top or bottom of the frame assembly (see Photo 17
& 18) and very slowly make minor adjustments in the second panel until it is level
and square with the first panel.
Photo 17 Photo 18
When the proper location has been achieved, torque all 32 of the 1/4-20 x 3/4"
screws at the panel block locations (see Photo 20) and the 16 1/4-20 x 1" screws
in the center of the two brace sub assemblies (see Photo 19). All of the screws
should be very securely tightened by hand. With the wrenches provided you
should apply maximum hand tightening force without straining yourself. Do not
use any extension or large wrenches that could over torque and strip the threads.
Photo 19 Photo 20
Installation of Remaining Adjustable Foot System - Unwrap the other two feet
supplied with the unit. Remove the screw and washer from each of the feet (see
Photo 21). Once the washer is removed, hand tighten the nut all the way down on
each individual foot. Then back the nut off one-half of a rotation on each foot
(see Photo 22).
Photo 21 Photo 22
Place the supplied washer on top of the nut and then screw each of the feet into
the threaded inserts on the bottom of the second panel (see Photo 23 & 24). The
feet should be threaded into the insert until the washer/nut come in contact with
the vertical panel threaded insert (insures maximum engagement between the
insert and the foot). Repeat this procedure and install the second foot to the
bottom of the second vertical panel.
