When Installing the Unit

• Refer all installation work to the dealer from whom the speaker was purchased. Installation requires extensive technical knowledge and experience. The speaker may fall off if incorrectly installed, resulting in possible personal injury.

• 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.

• Attach the safety wire to the unit. If not attached, the unit could fall off, resulting in personal injury.

• Use bolts and nuts that are appropriate for the wall's material and structure. Failure to do so may cause the unit 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.

• Use the specified mounting bracket and matching transformer in combination. Doing otherwise may cause the unit to fall off or generate heat, resulting in personal injury or fire.

• 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.

• Avoid installing the speaker in indoor swimming facilities that are not well ventilated. In such locations, the bracket may be vulnerable to corrosion, eventually allowing the speaker to fall resulting in personal injury.

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.

Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

WARNING

When Installing the Unit

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

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.

• Avoid connecting to an 83 Ω tap when using the speaker on high impedance 100 V line. Otherwise, heat builds up in the matching transformer, possibly causing a fire.

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

CAUTION

2. GENERAL DESCRIPTION

The TOA SR-T5 is a 2-way line array speaker in which low- and high-frequency speaker units are arranged vertically within close proximity to each another. Its excellent speech clarity and sturdy impact-resistant construction make it ideal for installation in sports facilities with strong reverberation, such as school gymnasiums.

3. FEATURES

• Two-way line array speaker employs 8 of 13 cm (5.12") woofers and 24 of small tweeters.

• Curved vertical speaker arrangement covers entire audience area with uniform sound volume from front to rear.

• Since the spread of speaker sound is suppressed in the vertical direction, the speaker is not subject to the influence of rear wall or ceiling, allowing clear audio output even in spaces with poor acoustic conditions due to long reverberation.

• Sturdy impact-resistant construction allows the speaker to be used without requiring additional protector grilles, even in gymnasiums.

• Internal two-way passive crossover network circuitry adaptable to single-amplifier operation.

• Supplied mounting bracket permits the speaker’s downward angle to be adjusted by 1°, 2°, or 3° from the 0° position (where mounted flat to a wall). Additional use of the optional SR-PB5 Wall Pan Bracket permits either 5 ° or 10° left or right in horizontal angle adjustment.

• Optional MT-S0601 Matching Transformer permits use in high-impedance applications.

• Safety wire supplied to prevent the speaker from falling during installation work and after installation.

About the input over-voltage protection circuitry

The speaker system has a built-in input over-voltage protection circuitry for the tweeters. If an excessive input signal is applied to the speaker, the protection circuitry works to cut off the signal input to the tweeters. A sudden drop of the volume level in high frequencies during speaker operation indicates that the overvoltage protection circuitry has been activated. In such a case, reduce the amplifier volume and wait. The protection circuitry is automatically reset in approximately 10 seconds. After the situation returns to normal, set the volume at a level lower than before.

6. INPUT TERMINAL CONNECTION

Step 1. Run the speaker cable through the cable entry hole in the speaker's rear panel, then lead it out from

the side panel. Pull out the cable slightly longer than needed from under the input terminal for ease of wiring.

Step 2. Connect the speaker cable to the input terminal.

Pull the speaker cable from the speaker's rear side to take up the slack.

Note

Pay attention to the correct polarity at the time of connection.

Step 3. Attach the supplied side cover.
