- 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


To avoid the possibility of malfunction/damage to the product, damage to data, 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.


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 strap.

• 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.

VXC4/VXC4W O-ring












Install the speakers onto the ceiling with the supplied hardware. Ensure that the strength of the ceiling rail is sufficiently strong.

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.)

There are two acceptable wiring methods.


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.

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

When all the Anti-Drop tabs cross over the O-ring, the speaker is held temporarily. You can release your hands from the speaker.

8 Close the terminal cover and tighten the screw.

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 cabinet’s face.


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



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 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 Pull the wiring from the amplifier through the cut hole.

2 Loosen the screw at the right of the terminal cover to open the terminal cover and remove the Euroblock connector.

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.

4 Plug the connected Euroblock connector into the socket in the speaker.




1 Attach the safety wire to the safety wire ring, and connect the wire to an independent support point, such as a joist.

3 Turn the screwdriver a half turn counterclockwise to loosen the attachment screw. This makes the clamp easier to align in the channel.

4 Turn 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.

Safety wire ring



Always take measures to prevent the speaker falling down.

If the safety wire is too short, prepare another wire appropriate 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.

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


• Do not over-tighten the attachment screw. Otherwise, the attachment screw and clamp will break.

• Do not turn any screws that do not have a guide sleeve in the screw hole. 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.

Terminal cover

3 After 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.

5 Loosen the screw A of the strain relief clamp.

6 Remove 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.




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.



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

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

Less than 3 mm (0.1 in.) CAUTION

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