NOTICE
To avoid the possibility of malfunction/damage to the product or damage to other
property, follow the notices below.
●Handling and maintenance
• When using a high-impedance speaker connection, make sure the audio
signal is passed through an 80 Hz or above high-pass filter before being input
to the speakers.
• Do not expose the device to excessive dust or vibration, or extreme cold or
heat (such as in direct sunlight, near a heater, or in a car during the day), in
order to prevent the possibility of panel disfiguration, unstable operation, or
damage to the internal components.
• Do not place vinyl, plastic or rubber objects on the device, since this might
discolor the panel.
• When cleaning the device, use a dry and soft cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths.
• Condensation can occur in the device due to rapid, drastic changes in
ambient temperature-when the device is moved from one location to another,
or air conditioning is turned on or off, for example. Using the device while
condensation is present can cause damage. If there is reason to believe that
condensation might have occurred, leave the device for several hours without
turning on power until the condensation has completely dried out.
• Be sure to observe the amplifier’s rated load impedance (see General
Specifications), particularly when connecting speakers in parallel. Connecting
an impedance load outside the amplifier’s rated range can damage the
amplifier.
• 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.
• Air blowing out of the bass reflex ports is normal, and often occurs when the
speaker is handling program material with heavy bass content.
• Do not swing the speaker by its carrying band.
• 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.
• Do not touch the speaker driver unit.

Using Loop-Through Terminals
For this method, cables are connected from terminals 1 and 4 to the
subsequent speaker. Cables with a thickness up to AWG 12 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.

Installing the Speakers
Install the speakers onto the ceiling with the supplied hardware. Ensure that
the strength of the ceiling rail is sufficiently strong.
Illustrations in this manual are for the VXC3F. The installation method is the
same for other models.
CAUTION
When attaching the speakers, turn off the power amplifier.
Pre-installation (Preparation of the Cable)
• Use stranded wire for cables attached to the Euroblock plug. Strip their
insulation as shown in the figure and connect them.
Note
Do not plate stranded wires by solder. Doing so will cause the wire to
break.
• Make sure that the release lever of the baffle front is in the position as
shown in the figure below.
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.
Note
If you use a circular cutter, set the diameter with the cutout template.
2 Cut the hole by tracing the circle.
Be careful to prevent chips or powder entering your eyes while
cutting the hole.
1 Insert the two tile rails through the cut hole and place them on the
ceiling surface within your reach. Be sure that each tile rails are
oriented as shown below.
2 Insert the folded O-ring through the cut hole and open it in the ceiling.
3 Secure the O-ring and tile rails with supplied two screws through
either slot of both O-ring brackets.

1 Take care not to trap the cable, carrying band, or safety wire while
slowly pushing the speaker up into the ceiling.
Make sure the release lever is in the position of the figure below. If it
is set to the position of the figure, when all the Anti-Drop tabs cross
over the O-ring, the speaker is held temporarily.
2 While slightly lifting up the speaker, turn the screwdriver clockwise to
tighten the attachment screw.
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.
Note
When the clamp is difficult to open, turning the screwdriver halfway
counterclockwise once will make it easier to open the clamp.
CAUTION
• Do not over-tighten the attachment screw. Otherwise, the
attachment screw and clamp will break.
• Do not turn any screws other than attachment screw. Otherwise,
the speaker may fall or malfunction.

Fix the Speakers onto the Ceiling
For safety, use the screw hole on the speaker (M5 × 12 mm) and
connect the wire to an independent support point such as a joist.
Example of the connection using an eye bolt
CAUTION
Always take measures to prevent the speaker from falling down.
Use a safety wire of appropriate length. Should the speaker fall and the
wire is too long, the wire may snap due to excess strain.
