INSTRUCTION MANUAL

1. SAFETY PRECAUTIONS

• Be sure to read the instructions in this section carefully
before use.

• Make sure to observe the instructions in this manual as
the conventions of safety symbols and messages
regarded as very important precautions are included.

• We also recommend you keep this instruction manual
handy for future reference.

WARNING Indicates a potentially

hazardous situation which, if mishandled, could result in
death or serious personal injury.

• Use only the specified amplifier output voltage and
impedance, as exceeding the specified limits could result
in fire or other failures (high-impedance applications).

• To avoid accidental air explosions, do not use the unit
around gasoline, thinner or other combustibles.

• 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.

• Use nuts and bolts that are appropriate for the ceiling's
or wall's structure and composition. Failure to do so may
cause the speaker to fall, resulting in material damage
and possible personal injury.

• Tighten each nut and bolt securely. Ensure that the
bracket has no loose joints after installation to prevent
accidents that could result in personal injury.

• Attach the safety wire to the unit when mounting in
locations high above the ground. Failure to do so could
result in personal injury if the speaker should later fall for
any reason.

WARNING Indicates a potentially

hazardous situation which, if mishandled, could result in
death or serious personal injury.

• Avoid mounting the unit in locations exposed to constant
vibration. The mounting bracket can be damaged by
excessive vibration, potentially causing the speaker to
fall, which could result in personal injury.

CAUTION Indicates a potentially hazardous

situation which, if mishandled, could result in moderate
or minor personal injury, and/or property damage.

• To avoid electric shocks, be sure to switch off the
amplifier power when connecting the speaker.

• Avoid installing the unit in humid or dusty locations, or in
locations exposed to heaters, solvents, acid, alkali,
smoke, or steam, as excessive exposure to these factors
could result in the speaker falling off, electric shock or
fire.

• 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 stand or sit on, nor hang down from the unit as
this may cause it to fall down or drop, resulting in
personal injury and/or property damage.

• Have the unit periodically checked by the shop from
where it was purchased. Failure to do so could result in
the speaker falling off due to damage or corrosion to the
speaker or its mounts, and possible personal injury.

2. FEATURES

• The speaker's smoothly curved surface permits it to
blend in with virtually all modern buildings.

• A built-in matching transformer permits the speaker to be
used for both high-impedance and low-impedance (8 Ω)
applications. The impedance can be easily changed from
outside the speaker.

• A splash-proof design enables the BS-1030 to even be
installed outdoors, in a location not directly exposed to
the elements, such as under eaves.

• Mountable to wall surfaces directly or using with supplied
or optional mounting brackets.

3. INPUT IMPEDANCE CHANGE

The speaker's input impedance is preset to 30 W (330 Ω)
of 100 V line by the factory. To change the impedance,
change the position of the rear panel-mounted rotary
switches with a slotted screwdriver.

3.1. High Impedance (70 V or 100 V Line) Applications

Set the [LINE VOL.] rotary switch to the 70 V or 100 V
position, and the [INPUT] rotary switch to the wattage to be
used. (The figure below is an example of 100 V, 20 W.)

3.2. Low Impedance Applications

Notes

To avoid damage to the speaker, be sure to follow the
instructions below.

• Switch off the amplifier power when changing the input.

• Never set the [INPUT] switch to the [8 Ω] position when

the [LINE VOL.] switch is set to the 70V or 100 V (high
impedance) position.

4. SPEAKER INSTALLATION

4.1. Wall Mounting – With Surface-Mount Screws

Note: The surface-mount screws are not supplied with

the unit. Referring to the mounting hole's dimensional
diagram below, prepare the correct type of screws
appropriate to the wall material.

6 mm

16 mm

ø16 mm

Step 1. Install two surface-mount screws in the wall 50 mm

apart and leave them sticking out approximately 3
– 5 mm from the wall surface.

Step 2. Connect the speaker cable.

Step 3. Place the speaker's rear panel mounting holes

over the two installed screws to mount the speaker
to the wall surface.

Note

Route the speaker cable as
shown in the figure so that it is
not pinched between the speaker
and the wall surface.

Tip

When installing the speaker horizontally, use the relevant
mounting holes shown below.
