port’s oval holes with the threaded holes on the back of your TV. Se-
cure the Sandwich Support to the back of the TV using the TV manu-
facturers recommended hardware. Please note: The UM1-A bracket
assembly should always be mounted between the TV and the TV
mount. Ensure that the bolts go through all of the hardware being used
into the back of the TV

Mounting your Sonos® ARC
 Supports 300mm to 600mm horizontal VESA patterns ONLY
 Mount the L/R sides of the UM-1 bracket to the back of the TV
 For 600mm horizontal VESA spacing, swap the Sandwich brackets
mounting location so that the attached Vertical brackets mount go-
ing towards the center of the display. This will allow the ARC
adapter bracket to reach the threaded inserts on the Sonos® ARC
 Please note: The Sandwich, Vertical and ARC adapter brackets
may be flipped in various ways providing additional adjustment op-
tions. The right placement will depend upon your application
 Attach the ARC adapter
brackets using the in-
cluded 1/4” carriage
bolts and 1/4” nylon
nuts to the vertical sup-
port bracket

 Secure the ARC adapter
bracket to the back of the
Sonos® ARC by using the
provided hardware in this
recommended order: 18mm
M5 bolt, lock washer, flat
washer, fender washer and
then into the Sonos® ARC
using the hex key. We
strongly suggest two people
perform this action to ensure
that you do not drop the
Sonos® ARC while securing
to the ARC adapter brackets
 Use the Height, Forward/Depth, and
Tilt adjustments to place the Sonos®
ARC in your desired location and
lock into place using the nylon nuts.
Do not over tighten
 At a minimum, ensure that the back
of the speaker grill on the Sonos ARC
clears the front edge of the display.
This will allow the Atmos drivers to
remain unobstructed
 When using a Tilt Mount—Use the Tilt adjustment feature to re-
level the Sonos® ARC so that the Atmos drivers fire up from a lev-
el plane
Do not mount the Sonos® ARC above the TV
