• 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.

• When turning on the AC power in your audio system, always turn on the power amplifier LAST, to avoid speaker damage. When turning the power off, the power amplifier should be turned off FIRST for the same reason.

• 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 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.

• 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.

• 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.

Protective 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.

Connecting the Wiring to the Speakers

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

3.2 Pass the cables through the cable gland attached to the terminal cover.

Terminal cover

3.5 Tighten the cap of the cable gland.


4.3 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.

4.4 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.

Power amplifier


* You can use this terminal to hook up an earth cable, as necessary.


When connecting with low impedance, take note of the combined resistance.


When connecting with high impedance, refer to “Better Sound for

Commercial Installations” (English only) of the Yamaha Pro Audio web site, at the following URL.

http://www.yamahaproaudio.com/global/en/training_support/ better_sound/

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-VA. The installation method is the same for other models.

Pre-installation (Preparation of the Cable)

Use stranded wire for cables attached to the ceramic terminal. Strip their insulation as shown in the figure and connect them.

About 7 mm (0.3")


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


Cut Out a Hole in the Ceiling

1.1 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.

1.2 Cut the hole by tracing the circle.

Be careful to prevent chips or powder entering your eyes while cutting the hole.


Install the Tile Rails and O-ring

2.1 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.

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

2.3 Secure the O-ring and tile rails with supplied two screws through either slot of both O-ring brackets.

Cable gland

If it is difficult to pass all the cables through a single cable gland, open the hole in the terminal cover and attach a commercially available cable gland.


Fix the Speakers onto the Ceiling

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

Safety wire ring


Prepare a cable gland of AVC part no. PGB 13.5-12B.


Use an appropriate tool for opening the hole. Otherwise, you may be injured if you open the hole with your bare hands.

3.3 Loosen the terminal screws of the ceramic terminal with a flat-blade screwdriver, insert the cables into each terminal and tighten the screws. Pull on the cables to make sure they are tightly secured and will not come loose.




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.

4.2 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 other than attachment screw (located beside the U mark). Otherwise, the speaker may fall or malfunction.


Set the Line Voltage/Impedance and Power

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 illustration indicates the setting at 60 W for 100 V line and 30 W for 70 V line.


• 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.


Attach the Grille

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


Anti-Drop Tab

* Use the Earth terminal as necessary.


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

Less than 3 mm (0.1 in.)

3.4 Close the terminal cover and tighten the screws.

When all the Anti-Drop Tabs cross over the O-ring, the speaker is held temporarily.


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

The installation is complete.

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.
