NOTICE

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

Handling and maintenance

• Do not expose the product to excessive dust or vibration, or extreme cold or heat, in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the internal components.
• Be sure to observe the amplifier’s rated load impedance, particularly when connecting speakers in parallel at low impedance. 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 60 Hz or above high-pass filter before being input to the speakers.
• Do not touch the speaker driver unit, since it might cause malfunction.
• Do not place vinyl, plastic or rubber objects on the product, since this might cause alteration or discoloration of the panel.
• When cleaning the product, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths, since this might cause alteration or discoloration.
• 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 place the speaker face down with the grille attached, as deformation of the grille may result.
• When placing the baffle face down, always place it on a flat surface.

Installing the Speaker

Before installing the speaker onto the ceiling, ensure that the strength of the
ceiling rail is sufficient.

CAUTION
Be careful not to hurt your hands when handling this product.

NOTICE
When installing the speakers, turn off the power amplifier.

Pre-installation (Preparation of the Cable)

For cables attached to the spring type connector, strip the insulation as shown in the figure and connect them.
Compatible cable:
Min. AWG18 (0.75 sq)
Max. AWG12 (3.5 sq) for solid core wire/
AWG14 (2 sq) for stranded wire

NOTE
Do not plate core wires by soldering if the cable uses stranded wire.
Doing so will cause the wire to break

Cut Out a Hole in the Ceiling

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 using the cutout template.
2. Cut the hole by tracing the circle.

CAUTION
Wear goggles to prevent chips or powder entering your eyes while cutting the hole.

When the included Reinforcing Bracket Kit or AB-C2 (sold separately) is used

For the VC8NB, VC8NW, VC6NB, and VC6NW, the included Reinforcing Bracket Kit must be used.
For the VC4NB and VC4NW, follow the instructions when using the ABC2.

1. Insert the two tile rails through the cut hole and place them on the ceiling surface within your reach. Adjust their length and be sure that each of the tile rails are oriented as shown below.

2. Use the opening in the C-ring to slide one section of the C-Ring into the cut hole, continuing to slide it around until the C-ring is completely inside the ceiling.
   

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

Connect the Wiring to the Connector

1. Pull the wiring from the power amplifier through the cut hole of the ceiling.
   The dust-proof bag has notches at the spring type terminal and a safety wire so that you can work with the dust-proof cover attached.
   

2. Insert the cable into each terminal.
   Insert the cable while holding the lever, and when fully inserted, release your finger from the lever to securely connect. (Lever operation is not required for solid core wire.) Make sure that the cables cannot be pulled out.
   
   

Fix the Speaker onto the Ceiling

1. From the hole on the top of the dust-proof cover, 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 from falling down.
   If the safety wire is too short, prepare another wire appropriate for the speaker weight and installation conditions.

2. Push the speaker slowly up into the ceiling, taking care not to trap the speaker cable or safety wire.
   VC4NB, VC4NW)
   When the AB-C2 Reinforcing Bracket Kit (sold separately) is not used.
   (VC4NB, VC4NW, VC6NB, VC6NW, VC8NB, VC8NW)
   When the included Reinforcing Bracket Kit or AB-C2 (sold separately; VC4NB and VC4NW only) is used.

3. While lifting up the speaker, turn the screwdriver clockwise to tighten the attachment screw.
   The first turn of the attachment screw opens the clamp. Further turns move the clamp down the channel to pull the speaker up into the ceiling. When the clamp is difficult to open, turning the screwdriver halfway counterclockwise once will make it easier to open the clamp.

NOTICE
Do not over-tighten the attachment screws. Otherwise, the attachment screws and clamps will break.

Removing from the Ceiling

1. While pressing the speaker against the ceiling, loosen the attachment screws by turning them counterclockwise. Loosen the screw and the clamp goes up, and as it reaches the top, the clamp closes as shown in figure below.
   

2. Remove the safety wire from the speaker that is detached from the ceiling.

Set the Line Voltage/Impedance and Power

Select the line voltage/impedance (100 V, 70 V, 16 Ω) and power tap for a 100 V, 70 V line distributed system, by rotating the tap selector switch on the front side of the speaker with a flat-blade screwdriver.
When using the speaker with high-impedance connection, select the position where wattage is indicated by the line (100 V, 70 V). Do not select the “ × ” setting when connecting to a 100 V line.
When using it with low impedance connection, select the 16 Ω position.

The illustration indicates the setting at 6 W for a 100 V line and 3 W for a 70 V line.

NOTICE

• Make sure the amplifier is switched off before operating the tap selector switch.
• If the setting is incorrect, it may cause malfunction of the speaker and amplifier.

Attach the Grille

1. Align the grille with the cabinet’s face and fit them together.
2. Turn clockwise (approx. 30°) to secure the grille.
   

CAUTION

• If the grille is not sufficiently turned, it may fall off. Sufficiently turn the grille, until the fastening sections of the grille and speaker are securely engaged.
• If the ceiling material is soft, the baffle surface may sink into the ceiling material due to overtightening of the attachment screws, and the grill may not fit properly.
