property, follow the notices below.

ƔHandling 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 t o 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 t he 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.

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.

NOTE

Do not plate stranded wires by solder. Doing so will cause the wire to break.

1Put 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.

2Cut the hole by tracing the circle.

Be careful to prevent chips or powder entering your eyes while

cutting the hole.

1Insert 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.

2Insert the folded O-ring through the cut hole and open it in the ceiling.

3Secure the O-ring and tile rails with supplied two screws through

either slot of both O-ring brackets.

1Pull the wiring from the amplifier through the cut hole.

2Loosen the screw at the right of the terminal cover to open the

terminal cover and remove the Euroblock connector.

3After loosening the terminal screws of the Euroblock connector with a

flat-blade screwdriver, insert the cable into each terminal and tighten

the screws. Make sure that cables cannot be pulled out.

NOTE

Use a flat-blade screwdriver with a blade less than 3 mm (0.1 in.).

There are two acceptable wiring methods.

CAUTION

When connecting with low impedance, take note of the combined

resistance.

Using Loop-Through Terminals

For this method, cables are connected from terminals 1 and 4 to the

subsequent speaker. If the Euroblock connector 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. Since the cables are connected via Euroblock connectors,

subsequent speakers can work even if a problem occurs with a

speaker.

4Plug the connected Euroblock connector into the socket in the

speaker.

5Loosen the screw A of the strain relief clamp.

6Remove the screw B of the strain relief clamp.

If the cable is not to be held, remove the screw A and remove the

strain relief fitting, then proceed to step 8.

7Hold the cable in the strain relief clamp, then tighten screws A and B.

8Close the terminal cover and tighten the screw.

1Attach the safety wire to the safety wire ring, and connect the wire to

an independent support point, such as a joist.

CAUTION

Always take measures to prevent the speaker from falling down.

If the safety wire is too short, prepare another wire appropriate for th e

speaker weight and installation conditions. If the wire is too long,

should the speaker fall, the wire may snap as a result of too much

strain.

2Push up the speaker slowly into the ceiling, taking care not to trap the

cable.

4FIX THE SPEAKERS ONTO THE CEILING

Safety wire ring

Anti-Drop Tab

When all the Anti-Drop Tabs cross

over the O-ring, the speaker is held

temporarily.

To release the speaker from the

O-ring, press the Anti-Drop Tabs.

These are located above the U

mark near the edge of the baffle’s

face.

3Turn the screwdriver a half turn counterclockwise to loosen the

attachment screw (located beside the U mark). This makes the

clamp easier to align in the channel.

4Turn the screwdriver clockwise to tighten the attachment screw.

The first turn of the attachment screw aligns the clamp with the

channel. Further turns move the clamp down the channel to pull the

speaker up into the ceiling.

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 (located

beside the U mark). Otherwise, the speaker may fall or

malfunction.

Select the line voltage/impedance (100V/70V/8Ω) and power tap for 100V/

70V line distributed system, by rotating the tap selector switch on the front

side of the speaker with a flat-blade screwdriver.

CAUTION

• The “X” position should not be selected. The 8Ω position should be

selected for 8Ω audio systems only. If the setting is incorrect, it may

cause malfunction of the speaker and amplifier.

• Make sure the amplifier is switched off before operating the tap selector

switch.

Fit the grille to the baffle front and turn it clockwise.

CAUTION

The grille may fall down if it is attached inadequately. Attach it firmly.
