CAUTION

When Installing the Unit

• 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.

• Since the unit is designed for in-door use, do not
install it outdoors. If installed outdoors, the aging of
parts causes the unit to fall off, resulting in personal
injury. Also, when it gets wet with rain, there is a
danger of electric shock.

• Owing to the unit's size and weight, be sure that at
least two persons are available to install the unit.
Failure to do so could result in personal injury.

• 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.

• Do not mount the unit in locations exposed to
constant vibration. The mounting bracket can be
damaged by excessive vibration, potentially
causing the unit to fall, which could result in
personal injury.

• Do not use anti-rust lubricant. If it contacts resin or
rubber parts, they could deteriorate and cause the
unit to fall, possibly resulting in personal injury.

When Installing the Unit

• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.

• When unpacking or moving the unit, be sure to
handle it with two or more persons. Falling or
dropping the unit may cause personal injury and/or
property damage.

• Avoid placing the unit in a doorway or other high
traffic area as people may trip on the equipment
and cords, or be injured by falling objects.

• Avoid touching the unit's sharp metal edge to
prevent injury.

• To avoid electric shocks, be sure to switch off the
amplifire's power when connecting speakers.

When the Unit is in Use

• Do not place heavy objects on the unit as this may
cause it to fall or break which may result in
personal injury and/or property damage. In
addition, the object itself may fall off and cause
injury and/or damage.

• Do not operate the unit for an extended period of
time with the sound distorting. Doing so may cause
the connected speakers to heat, resulting 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 checked periodically by the shop
from where it was purchased. Failure to do so may
result in corrosion or damage to the unit or its
mounting bracket that could cause the unit to fall,
possibly causing personal injury.

1. SAFETY PRECAUTIONS

operation.

• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or
cautions regarding safety.

2. GENERAL DESCRIPTION

Designed for indoor use, the BS-301 series is a 2-way speaker system featuring high power handling.
Consisting of 4 satellite speakers and a subwoofer, this speaker system delivers a high sound pressure level
over a wide frequency range of sound. It is ideal for installation in small shops and BGM applications.
The supplied mounting bracket permits the speaker system to be installed at various sites and various
direction angles.

3. DESCRIPTION ON OVERLOAD PROTECTION

The speaker unit is equipped with an overload protection circuitry. This circuitry will protect the speaker unit
from overload input which exceeds the allowed capacity.
Speaker's volume will turn lower if the input to the speaker exceeds the maximum capacity of the speaker.
In such event, please turn down the amplifier volume to the minimum level and wait for about 10 seconds. The
circuitry will automatically revert to normal condition. Then, set the volume at a lower level than before.

Note

The overload protection circuitry does not completely protect the speaker unit against overload. Prolonged
overload input to the speaker unit will cause the system to malfunction. As such, the overload input will flow in
and damage the speaker unit.
It is important to prevent prolonged overload input exceeding the maximum limit from flowing into the speaker
unit.
