Using Loop-Through Terminals
For this method, cables are connected from terminals 1 and 4 to the
subsequent speaker. Cables with a thickness of at least AWG24 (0.2 sq)
and up to AWG12 (3.5 sq) can be used. If the Euroblock plug is
disconnected from a speaker, all subsequent speakers will not work. This
can be useful to identify which speaker has a problem.
Paralleling Input Terminals
For this method, cables are connected to terminals 2 and 3 of each
speaker. Connect two cables to one terminal. Cables with a thickness up
to AWG 17 can be used. Since the cables are connected via Euroblock
plugs, subsequent speakers can work properly.

CAUTION
• When connecting with low impedance, take note of the total impedance.
• When connecting speakers with high impedance, be sure that the total rated input capac-
ity of the speakers does not exceed the output power of the amplifier.
NOTICE
When using a high-impedance speaker connection, make sure the audio signal is passed through an
60 Hz or above high-pass filter before being input to the speakers.
Installing the Speaker
Before installing the speaker onto the ceiling, ensure that the strength of the
ceiling rail is sufficient.
Pre-installation (Preparation of the Cable)
• For cables attached to the Euroblock
plug, strip the insulation as shown in the
figure and connect them.
1. Put the supplied cutout template to the ceiling and draw a circle by
tracing it.
Make sure to use the cutout template so that hole is the correct
diameter.
If you use a circular cutter, set the diameter using the cutout template.
2. Cut the hole by tracing the circle.
1. Insert the two tile rails through the cut hole and place them on the ceiling
surface within your reach. Adjust their length and be sure that each of
the tile rails are oriented as shown below.
2. Insert the folded O-ring through the cut hole and open it within the
ceiling.
3. Secure the O-ring and tile rails with the supplied two screws through
either slot of both O-ring brackets.
1. Pull the wiring from the power amplifier through the cut hole of the
ceiling.
2. Loosen the screws of one of the two terminal covers according to the
wiring direction and remove the terminal cover.
Pass the cable through the terminal cover.
In this manual, the illustrations show the top terminal cover removed.
The terminal covers do not have a hole
through which the speaker cable passes.
Open a hole in the terminal cover (as shown)
to use.
3. Remove the Euroblock plug from the speaker. After loosening the
terminal screws of the Euroblock plug with a flat-blade screwdriver,
insert the cable into each terminal and tighten the screws. For the
connection, refer to section “Connecting the Cable.” Make sure that
cables cannot be pulled out.
Use a flat-blade screwdriver with a
blade less than 3 mm.
4. Plug the connected Euroblock plug into the socket in the speaker.
5. Tighten the screw and then attach the terminal cover.
NOTICE
When installing the speakers, turn off the power amplifier.
NOTE
Do not plate core wires by soldering if
the cable uses stranded wire. Doing so
will cause the wire to break.
NOTICE
Make sure that the release
lever of the baffle front is in the
position as shown in the figure.
Cut Out a Hole in the Ceiling
CAUTION
Wear goggles to prevent chips or powder entering your eyes
while cutting the hole.

1. Attach the safety wire to the safety wire ring, and connect the wire to an
independent support point, such as a joist.
3. While slightly lifting up the speaker, turn the screwdriver clockwise to
tighten the attachment screw.
The attachment screws are indicated by marks.
The first turn of the attachment screw opens the clamp. Further turns
move the clamp down the channel to pull the speaker up into the ceiling.
When the clamp is difficult to open, turning the screwdriver halfway
counterclockwise once will make it easier to open the clamp.
Select the line voltage/impedance (100V, 70V,
8Ω) and power tap for a 100V, 70V line distributed
system, by rotating the tap selector switch on the
front side of the speaker with a flat-blade
screwdriver. When using the speaker with a high-
impedance connection, select the position where
wattage is indicated by the line (100V, 70V). Do
not select the “ × ” setting when connecting to a
100V line. When using it with low impedance
connection, select the 8Ω position.
Attach the string to the speaker as shown in the figure, and then fit the grille
to the magnets (8 places) on the baffle front.
Fix the Speaker onto the Ceiling
CAUTION
Always take measures to prevent the speaker from falling
down.
If the safety wire is too short, prepare another wire appropri-
ate for the speaker weight and installation conditions. If the
wire is too long, should the speaker fall, the wire may break
as a result of too much strain.
NOTICE
Do not over-tighten the attachment screws. Otherwise, the attachment
screws and clamps will break.
CAUTION
Do not turn any screws other than the attachment screws.
Otherwise, the speaker may fall or malfunction.

filter before being input to the speakers.
• Do not touch the speaker driver unit, since it
might cause malfunction.
• Be sure to observe the amplifier’s rated load
impedance, particularly when connecting
speakers in parallel at low impedance.
Connecting an impedance load outside the
amplifier's rated range can damage the
amplifier.
• Do not place vinyl, plastic or rubber objects on
the product, since this might cause alteration
or discoloration of the panel.
• When cleaning the product, use a dry and soft
cloth. Do not use paint thinners, solvents,
cleaning fluids, or chemical-impregnated
wiping cloths, since this might cause alteration
or discoloration.
• Protection Circuit
This speaker system has an internal protection
circuit that shuts off the speaker unit when an
excessive input signal is applied. If the
speaker unit emits no sound, reduce the
volume level of the amplifier immediately. (The
sound will return automatically in several
seconds.)
• Do not place the speaker face down with the
grille attached, as deformation of the grille may
result.
• When placing the speaker face down, always
place it on a flat surface.
• Air blowing out of the bass reflex ports is
normal, and often occurs when the speaker is
handling program material with heavy bass
content.
