Grace Design m904RCU – No Longer Available

Remote control unit for m904/m904b

Product Description

The m904RCU from Grace Design is a high-quality wired remote control unit for use with the m904 and m904b stereo monitor control units.  This remote is required for control of the m904b unit, and an optional add-on for the m904.

The remote provides full control over all aspects of the monitor units, including main volume and headphone level controls, talkback control, input channel selection, and more.  Because of the blank front panel of the m904b, the remote must be used.  The m904 has the exact same controls as the remote on its front panel, so adding the remote to the m904 provides you with a choice between local or remote control.


  • Tabletop controller for m904 and m904b
  • Controls input selection, volume level, talkback, muting, and more

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
