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
Set both the [LINE VOL] and [INPUT] rotary switches to
the [8 Ω] position.
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.
