The MXR Audio Stand is an industry leading design that eliminates noise, revealing a new level of musical performance. The frame itself is manufactured from six different materials including billet-machined aircraft aluminum and exotic finishes over a composite inner frame structure. The highly acclaimed HRS Isolation Bases load directly into the MXR frame as the shelf system. The MXR frame optimizes Isolation Base performance while offering unique flexibility and functionality.

  • Fully adjustable shelf system (quantity and location).
  • Load range of each shelf optimized for maximum performance.
  • Leveling system with locking feature for stability.
  • Infinite cable access (no vertical or horizontal beams).
  • Structure design for optimum Isolation Base performance.
  • Unlimited expand-ability preserves initial investment.

Four ultra high frequency billet machined brackets support each shelf. The brackets are adjustable vertically allowing you to select ideal shelf spacing for your system. Regardless of the final shelf location you still will have infinite cable access because there are no front or rear braces to the main structure. You can also add or remove a shelf at any time without any modification to the rack structure or detracting in any way from its exceptional performance or beauty.

The MXR Audio Stand comes in a standard finish (Mahogany), two premium wood finishes (Walnut Burl and Birds Eye Maple),and many custom finishes (Contact HRS).  The MXR is also built in custom rack systems configurations, including side by side and custom sized systems.  HRS and our Authorized Dealers will work with you to make sure the MXR is an excellent compliment to an existing or new home decor. Please contact your local sales representative or HRS for more information.
