• This device contains no user-serviceable parts. Do not open the device or 

attempt to disassemble the internal parts or modify them in any way. If it 
should appear to be malfunctioning, discontinue use immediately and have it 
inspected by qualified Yamaha service personnel.

• Do not expose the device to rain, use it near water or in damp or wet 

conditions, or place on it any containers (such as vases, bottles or glasses) 
containing liquids which might spill into any openings. If any liquid such as 
water seeps into the device, have the device inspected by qualified Yamaha 
service personnel.

• Do not place the device in an unstable position where it might accidentally fall 

over.

• Do not place the device in a location where it may come into contact with 

corrosive gases or salt air. Doing so may result in malfunction.

• Construction work should be carried out in accordance with construction-

related law and always by a professional constructor. If the device installation 
requires construction work, make sure to observe the following precautions.

- Choose mounting hardware and an installation location that can support the 

weight of the device.

- Avoid locations that are exposed to constant vibration.

- Use the required tools to install the device.

- Inspect the device periodically.

• 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.

• 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.

• 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

To avoid the possibility of malfunction/damage to the product or damage to other 
property, follow the notices below.

• 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.

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.

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 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.

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.

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

About 7 mm (0.3 in.)

Less than 3 mm (0.1 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.

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.

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.

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

8 Close the terminal cover and tighten the screw.

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

an independent support point, such as a joist.

Always take measures to prevent the speaker from 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 snap as a result of too much 
strain.

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

cable.

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.

3 Turn 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.

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.

• 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.

• 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.

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

Clamp
