TOA SC-630M EB-Q Horn Speaker Instruction Manual

INSTRUCTION MANUAL
HORN SPEAKER SC-630M EB-Q1.

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 that 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.

WARNING Indicates a potentially hazardous situation that, if mishandled, could result in death or serious personal injury.
CAUTION Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.
WARNING

• 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.

CAUTION

• 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.

HOW TO USE

2.1. Handling Precautions

• When installing the speaker, be sure the drain hole is positioned facing the ground.
  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 nameplate as [70/100 V LINE]. If an unspecified line voltage is connected, fire or equipment failure could result.

2.2. Connections
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 nameplate.

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 nameplate.

****WARNING Do not use the impedance selector switch position marked as [X], because this position could result in amplifier or speaker failure, or fire.
