Dual Channel In-Ceiling
Speakers from EMPHASYS are de-
signed to deliver crisp, full-range sound
for today’s home theater and distrib-
uted audio environments, where digital
media places extreme demands on a
speaker’s capability. But while ordinary
speakers must be used in matching pairs
for correct stereo reproduction, the
Dual Channel In-Ceiling Series models
deliver awesome stereo sound from a
single speaker. EMPHASYS engineering
has combined a dual voice coil woofer
with twin tweeters, and as a result the
Dual Channel In-Ceiling models bring
high-quality stereo audio to even the
smallest room.
DC85 DC60
Positioning the Speakers
It is best, with the Dual Channel
In-Ceiling speaker or any
other unit, to position it
so that it aims directly
toward the listening
position. This will
ensure an accurate
stereo image and
help minimize the
creation of excessive
sound reflections.
If the listening room is
very large or the ceiling
is high, the DC85—with its 8"
aluminum woofer and greater power
handling—will be preferable to the DC60.

3. 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.
4. Cut the hole. CAUTION: This is the most important part of the in-
stallation. If you aren’t certain whether there are any obstructions
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. (See Diagram 2)
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.
5. 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.
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:
1. Choose the general location for the installation of each speaker,
being certain that these areas present no obstructions such as
electrical conduit, HVAC duct work or water lines.
2. Find the studs nearest the desired location for the speaker.
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.

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.

Painting the Speakers
If the speakers are to be painted, we recommend that it be done
before the speakers are actually installed. However, it is possible
to paint the speakers post-installation. Simply remove them from
the ceiling by reversing the order of the steps for installation
described earlier in this manual.
The paint masks provided in the carton must be installed between
the grille and flange while they are being painted. Be sure to
remove the white plastic blanket from beneath the grille before
painting the speaker. Once the grille has been painted, remove
the paint mask and return the acoustic blanket to its position
beneath the grille.
Be careful not to clog the holes of the grille. The sound of the
speakers will be dramatically reduced if the perforations in the
grille are covered in paint.
EMPHASYS recommends only light spray painting using five parts
thinning agent to one part paint.
Treble Adjustment
The Treble switch allows +3dB of adjustment from the “0” position,
where the most linear frequency response is maintained. If more
treble is desired, simply move the switch to the “+3” position. To
return to the neutral setting, move the switch back to the “0” posi-
tion. The Treble switch can be adjusted whenever desired.
(See Diagram 4)
Bass Adjustment
The Bass switch provides +3dB of bass adjustment from the “0”
position, where the flattest bass frequency response is maintained.
For extra bass, move the switch to the “+3” position. To return to
the neutral setting, move the switch back to the “0” position. As
with treble adjustment, the Bass switch can be moved whenever
desired. (See Diagram 4)

Tighten the four screws on the front of the baffle only so much that
the flange becomes snug against the ceiling. As you tighten the
screws, the feet will flip into an outward position (see Diagram 3),
clamping the drywall between the feet and the flange. CAUTION:
Excessive tightening may torque the baffle, crack the ceiling, cause
the white bezel to distort and make it difficult to seat the grille within
the grooves.
4. Push the grille firmly into the slot in the speaker baffle.
Installing the Speakers
Dual Channel In-Ceiling speakers feature a mounting system with
four swiveling feet for quick, secure installation. Use the following
steps:
1. Remove the grille. (To force the grille out of its retaining
groove, it may be necessary to push one or two of the mount-
ing screws and its attached foot toward the baffle and against the
inside surface of the grille.)
2. Attach the speaker wire (observing the proper polarity with
your amplifier, matching positive (red) to positive and negative
(black) to negative). Be certain the left channel of the amplifier
is connected to one input terminal, and that the right channel is
connected to the other.
3. Be sure the mounting feet are turned inward to clear the
opening, and then insert the speaker into the ceiling. Position the
speaker in the hole. Note: The flange of the speaker is designed to
conform to minor imperfections in the ceiling’s surface.
