1. SAFETY PRECAUTIONS

• Before installation or use, be sure to carefully read all

the instructions in this section for correct and safe

operation.

• Be sure to follow all the precautionary instructions in

this section, which contain important warnings and/or

cautions regarding safety.

• After reading, keep this manual handy for future

reference.

• Install the unit only in a location that can structurally

support the weight of the unit and the mounting bracket.

Doing otherwise may result in the unit falling down and

causing personal injury and/or property damage.

• Do not use other methods than specified to mount the

bracket. Extreme force is applied to the unit and the unit

could fall off, possibly resulting in personal injuries.

• Tighten all screws securely. If any is loosely fixed, this

may cause the unit to fall, resulting in personal injury.

• To avoid electric shocks, be sure to switch off the

amplifier's power when connecting speakers.

• Do not operate the unit for an extended period of time

with the sound distorting. This is an indication of a

malfunction, which in turn can cause heat to generate

and result in a fire.

• Do not hang down from the unit as this may cause it to

fall down or drop, resulting in personal injury and/or

property damage.

The PJ-64 and PJ-304 are projection speakers designed

for ceiling and wall installations. Considered in

architectural design, they can blend in with lighting

equipment.

The supplied swivel bracket allows for flexible speaker

angle adjustment.

The PJ-64 is driven on high-impedance (100 V and 70 V)

line, while the PJ-304 is driven on both high-impedance

(100 V and 70 V) and low-impedance (8 Ω) lines.

The input power (impedance) can be easily changed at

the upper side of the speaker.

The speakers are easy to repaint so as to meet a wide

range of design needs

(Factory-preset wiring)

The input power (impedance) is factory-preset to 6 W

(1.7 kΩ) for 100 V line and 3 W (1.7 kΩ) for 70 V line.

When changing this setting, use a standard screwdriver

to rotate the rotary switch on the upper side of the

speaker to the desired position

The input power (impedance) is factory-preset to 30 W

(330 Ω) for 100 V line.

When changing this setting, use a standard screwdriver

to rotate the rotary switches on the upper side of the

speaker to the desired position.

(1) When operating at high impedance (100 V and 70 V lines);

Set the rotary switch of "LINE VOL." to "100 V" or "70 V" and that of "INPUT" to the input power to be used.

(2) When operating at low impedance;

Set both rotary switches of "LINE VOL" and "INPUT" to 8 Ω.

Important

Be sure to follow the instructions below. Failure to do so may cause damage to the speaker.

• Switch off the amplifier's power when changing the input power.

• Never make 8 Ω connection in a 100 V or 70 V line system, as excessive input power is applied to the speaker,

possibly resulting in damage. (PJ-304 only)

5. INPUT POWER (IMPEDANCE) CHANGE

Note

Shown above is an example when the input power is

set to 3 W on 100 V line and 1.5 W on 70 V line.

Note

Shown above is an example when the input power is

set to 20 W on 100 V line.

6. INSTALLATION

Step 1. Secure the swivel bracket to the ceiling or wall with 3 screws.

Loosen the safety screw (for fall prevention) as shown below.

Before installation

Step 2. Mount the speaker to the swivel bracket.

Loosen the speaker fixing screws as shown below.

2-1. Pass the speaker cord through the cord entry hole in the swivel bracket.

2-2. Slip 2 speaker fixing screws into the swivel bracket's screw slots.

2-3. Tighten the speaker fixing screws and safety screw.

Before installation

Step 3. Connect the 60 cm (1.97 ft) speaker cord

to the routed speaker cable.

Step 4. Loosen the swivel bracket's butterfly nut,

adjust the speaker angle, and then

retighten the butterfly nut.

Note

If these screws are not appropriate for the ceiling material,

separately prepare the proper screws.

Note

Loosen the safety screw until it's tip does not stick out from the bracket surface.

If the screw tip sticks out, this obstructs the insertion of the speaker bracket in Step 2.

7. REPAINTING THE SPEAKER

Step 1. Remove 4 screws that fix the speaker

bracket to detach the speaker cover.

Step 2. Remove 3 screws that fix the mesh net,

then raise the turndown tabs of the mesh

net to detach.

Step 3. Clean the speaker cover and mesh net.

Wipe with a soft cloth damped in a detergent.

Note

Do not use thinner or other volatile liquids to clean them as doing so may cause deformation.

Step 4. Use spray paint to apply uniform and thin coat of paint.

Notes

• Avoid painting with a roller or brush, as the mesh net could become clogged with paint.

• Use appropriate paints for the speaker cover and mesh net materials.

· Speaker cover: Rolled steel plate (acrylic paint)

· Mesh net: Fire-resistant HIPS resin

Step 5. After the paint has dried, apply another light coat.

Repeating Step 4, apply 2 or more light coats of paint. Application of one thick coat of paint all at once

may cause drips or unevenness to show up in the painted finish, or clog the mesh holes.

Step 6. After the paint has dried, replace the speaker cover and mesh net.

Follow the procedure below when repainting the speaker cover and mesh net.

Note: Never touch the inner speaker diaphragm during work.
