Unpacking and Installing your m920
The m920 is shipped in one box which contains the
m920 unit, an AC power cord, a USB cable, a small
plastic bag containing four hand-threaded machined
metal feet and a warranty registration card.
OPEN AND INSPECT THE BOX
Open all shipping boxes, carefully remove the m920
and put it aside. Before you go any further, check to
make sure the above listed components are included
with your shipment. If you believe something is
missing, contact your Grace Design dealer and they
will make sure you’re taken care of.
SAVE YOUR BOX!!
We strongly encourage you to save the box and
shipping materials supplied with your m920. They
are specially designed to properly protect these
valuable components, and in the unlikely event that
you need to return them for service, only these OEM
shipping materials can ensure their safe return to our
factory.
REGISTER YOUR UNIT!
We strongly urge you to register your unit with
Grace Design. We provide a limited 5 year trans-
ferable warranty on all of our products, but if you
register your system, it’s easier for us to help you if
necessary. So please take a few minutes to complete
the enclosed warranty registration card and mail it
in, or you can simply go to the warranty registration
form on our web site. We do not share your informa-
tion with anyone. Thank you!
INSTALLING THE FEET
The m920 is designed to either be placed on a flat,
stable surface in your studio or listening environ-
ment, or be rack mounted. If you don’t plan to rack
mount your m920, first install the 4 supplied metal/
rubber feet. Simply thread the supplied feet by hand
into the 4 vacant threaded holes in each corner of
the underside of the m920.
RACKMOUNTING
For rack mount installation, the m920 chassis has a
#10-32 threaded insert mounting hole on the bottom
