Please follow the instructions in this manual to obtain the optimum results from this unit. We also recommend that you keep this manual handy for future reference.
The BS-1030 Series Speakers are small in size and feature the wide-band, high-quality, 2-way bass-reflex design which makes them ideal for such applications as announcements and music reproduction.
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.)

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.

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.
