property, follow the notices below.

●Handling and maintenance

• Do not expose the device to excessive dust or vibration, or extreme cold or

heat (such as in direct sunlight, near a heater, or in a car during the day), in

order to prevent the possibility of panel disfiguration, unstable operation, or

damage to the internal components.

• 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.

Installing the Speakers

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 ceramic terminal. 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.

1.1 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.

1.2 Cut the hole by tracing the circle.

Be careful to prevent chips or powder entering your eyes while

cutting the hole.

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.

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.

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.

Note

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

CAUTION

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.

Note

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

3.4 Close the terminal cover and tighten the screws.

3.5 Tighten the cap of the cable gland.

4.1 Attach 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 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.

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.

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.

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.

The installation is complete.
