INSTALLATION  
INSTALLATION  
The following is an overview  
of the installation of the  
Music Anywhere! In-Ceiling  
Kit. In some cases you  
should refer to the specific  
product manuals for addi-  
tional information.  
!
The Wall-Mount Volume  
Control should be installed  
indoors, in an interior wall  
relatively close to the area  
where the speakers will be  
mounted. The VCS-2D-IM  
Volume Control included  
with the Music Anywhere!  
In-Ceiling Kit is not water-  
proof and is not suitable  
for installation outdoors  
without a Niles WDC-100  
weatherproof cover.

Decide on an appropriate  
installation location for your  
In-Ceiling Speakers. They  
may be installed in any  
standard ceiling of at least  
a 3/8” thickness. Best results  
are achieved by installing  
the In-Ceiling Speakers an  
equal distance from the  
main listening position  
(See Page 10)  
FM 105.9  
Be sure to measure the  
approximate distance from  
your equipment to the  
Wall-Mount Volume Control  
location, and from the  
Wall-Mount Volume Control  
to the first and second  
Speaker locations. This  
will ensure that you have  
enough wire to complete  
the installation. The Music  
Anywhere! In-Ceiling Kit  
includes 100 ft. of 4-con-  
ductor Speaker Cable.
