Speaker Adjustments
Creating a Zone for Optimized Listening
The Dual Channel In-Ceiling speakers should be placed so that
they project, as much as possible, toward the listening position.
This will ensure an accurate stereo image and help minimize
the creation of excessive sound reflections.
If the speakers are to be mounted in a very high ceiling, the
pivoting tweeters of the DC85 should be aimed directly toward
the listening position.
(See Diagram 1)
In other cases it might be preferable to aim the tweeters slightly
outward, away from the listening position.
CAUTION: The tweeter dome, whether aluminum or silk, can be
damaged through direct contact with fingers or objects. Please be
careful when installing and adjusting the speaker.
Preparing the Surface for Mounting
Precautions for Installation
Careful consideration should be given to the possible presence of
electrical conduits, piping and other elements in the ceiling before
the Dual Channel In-Ceiling speakers are installed. If there is any
doubt regarding the most acceptable locations for the speakers,
please consult EMPHASYS Technical Support or the dealer.
New Construction: Unfinished Ceiling
A new construction bracket, available from your EMPHASYS
dealer, can be installed prior to drywall application across joists
(up to 24" on-center) where a speaker will be located. Once the
hole is cut and the drywall is installed, the speaker can be easily
installed in accordance with the instructions for mounting in "Fin-
ished Ceiling" below.
Finished Ceiling
Four-conductor wire should be run to the proper ceiling locations
before the speakers are affixed. To ensure a professional-looking
installation, observe the following steps:
Choose the general location for the installation of each speaker,
1.
being certain that these areas present no obstructions such as
electrical conduit, HVAC duct work or water lines.
Find the studs nearest the desired location for the speaker.
2.
EMPHASYS recommends the use of a good stud finder for this
procedure. If you are lining up the speakers to some other object
or molding in the room, be sure to allow for the size of the baffle
flange. This flange extends beyond the mounting hole
on all four sides of the Dual Channel In-Ceiling speaker.

Mark the hole. A template for setting the hole is provided in the

box (as are two paint mask inserts). Position the template in the
desired position and outline it on the ceiling using a pencil.
Cut the hole.

in the desired mounting area, use a drywall saw to cut a small
hole at the center of the spot you've outlined. Cut at a 45° angle
toward the inside of the hole.

Ceiling Cutout
You can use the piece cut out to fill the hole again, if obstructions
are found. Once the mounting location is deemed to be free of
obstructions, cut the outline at a 90° angle relative to the surface
of the ceiling.
If the area in the ceiling isn't already insulated, add insulation

material sufficient to fill the cavity. If the insulation material used is
faced with foil or paper, position the foil or paper away from the
speaker.
