Connections
• Before connecting the device to a power amplifier, turn off the power for all
devices. Before turning the power on or off for all devices, set all volume
levels to minimum.
• Use only speaker cables for connecting speakers to the speaker jacks. Use of
other types of cables may result in fire.
Maintenance
• Do not wipe the outer packaging with benzine, thinner, or synthetic detergent
and do not use electrical contact cleaner. These may damage the outer
packaging and dissolve the parts.
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 VXC6. The installation method is the
same for other models.
Pre-installation (Preparation of the Cable)
Use stranded wire for cables attached to the Euroblock connector. Strip
their insulation as shown in the figure and connect them.
About 7 mm (0.3 in.)
NOTE
Do not plate stranded wires by solder. Doing so will cause the wire to break.
1 CUT OUT A HOLE IN THE CEILING
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.
2 INSTALL THE TILE RAILS AND O-RING
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.

Handling caution
• Do not insert your fingers or hands in openings on the device.
• Do not operate the device if the sound is distorting. Prolonged use in this
condition could cause overheating and result in fire.
• When choosing a power amplifier for use with this device, make sure that the
output power of the amplifier is lower than the power capacity of this device
(see SPECIFICATIONS).
Even if the output power of the amplifier is lower than the power capacity of
this device (PGM), use of excessive input signals resulting in clipping may
cause damage to the device.
Malfunction or fire may occur especially when the following sounds or noises
are generated:
- feedback, when using a microphone
- continuous and extreme volume sound from a musical instrument
- extreme continuous distorted sound
- noise caused by plugging/unplugging the cable while the amplifier is turned
on
NOTICE
To avoid the possibility of malfunction/damage to the product or damage to other
property, follow the notices below.
●
Handling and Maintenance
• 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 until
the condensation has completely dried out.
• Be sure to observe the amplifier's rated load impedance (see
SPECIFICATIONS), particularly when connecting speakers in parallel.
Connecting an impedance load outside the amplifier's rated range can
damage the amplifier.
• When connecting the speakers with high impedance, be sure that the total
rated input capacity of the speakers does not exceed the output power of the
amplifier.
• 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.
• ABOUT THE 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 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 and smooth
surface.
• Do not touch the speaker driver unit.
