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.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
HORN SPEAKER INSTRUCTION MANUAL
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
WARNING
CAUTION
• Use only the specified amplifier output voltage and
impedance, as exceeding the specified limits could
result in fire or other failures (high-impedance
version).
• 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.
• Protect the unit from exposure in snowy areas, as
the weight of snow build-up could cause the
speaker to fall, resulting 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.
• 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.
• 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.
• 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.
• 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, steam or direct sunlight (except
outdoor-use versions), as excessive exposure to
these factors could result in speaker failure, fire or
electric shock.
• 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. Also, when mounting
the unit on a vehicle, be sure to check both the
speaker and its mounts before moving. 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. HOW TO USE
2.1. Handling Precautions
• When installing the speaker, be sure the drain hole is positioned facing the ground
(SC-610, SC-615, and SC-630 series). Without the drain hole positioned correctly, rain
could flood the speaker, causing it to fail.
• Be sure to note the following polarities when multiple speakers are used in the same location. Incorrect connections
could result in no bass output or decreased volume.
Black speaker cable: Positive (+), White speaker cable: Negative (–) or COM
Connect the cables to other cables of the same colors in parallel connections, and to cables of different colors in series
connections.
• To avoid amplifier failure, do not simultaneously connect both low- and high-impedance speakers to the amplifier.
Ensure that only one type is connected.
Notes: (1) "Low-impedance" refers to speakers having no built-in matching transformer.
(2) "High-impedance" refers to speakers having a built-in matching transformer.
• Ensure only the specified line voltage (amplifier output voltage) is used for the high-impedance speakers. The line
voltage is indicated on the name plate as either [25/70 V LINE] or [70/100 V LINE]. If an unspecified line voltage is
connected, fire or equipment failure could result.
2.2. Connections
2.2.1. Low-impedance speakers
When using two or more speakers, all connected speakers must have identical impedance and input ratings.
(1) The total speaker impedance must be equal to the amplifier output impedance. If the total speaker impedance is less
than the amplifier's output impedance, the speakers or amplifier could fail.
(2) When parallel-connecting all speakers, the total rated input of all the speakers must be greater than the amplifier output.
Note: It is highly recommended that solid wire speaker cable with diameter of over 2 mm or strand wire of over 3.5 mm
2
be used to minimize transmission loss. When there are long distances between amplifier and speaker (30 – 50 m),
connect an optional matching transformer to convert the speakers to high-impedance operation.
2.2.2. High-impedance speakers
The total rated input of all connected speakers must be equal to or smaller than the amplifier output. If the total speaker
input rating is greater than the amplifier output, the amplifier could fail. Connect all speakers in parallel.
2.3. Impedance Selection
Select the desired impedance by inserting a screwdriver into the impedance selector switch slot and turning the switch.
The OFF position disconnects the speaker from the amplifier and no sound is output.
Notes: (1) Speakers are factory-preset for the highest rated input of two line
voltages (i.e. 100 V line in the case of the 70/100 V line version).
(2) The speaker's rated input and impedance are indicated on the
name plate.
Speakers are designed to select either of the two line voltages (rated
amplifier output voltage). Check to confirm the line voltage to use, and
select the line voltage impedance specified on the name plate.
2.4. Assembling the Speaker
Speakers are packed in their cartons divided into the
following three parts: Bell, Center and Bracket. Assemble
these components as shown in the figure using four assembly
screws attached to the "Center."
Impedance marker
Impedance pointer
(Also function as a screwdriver slot.)
Impedance selector switch
Drain hole Center
Do not use the impedance selector switch position marked as [–], because
this position could result in amplifier or speaker failure, or fire.
