1. SAFETY PRECAUTIONS

When Installing the Unit

• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.

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

• Flying precautions. Be sure to follow the instructions below. Otherwise, the suspension wires or belts may be off or snap and the speaker may fall off, causing personal injury.

· Check to confirm that the suspension wires and

belts are strong enough to

· The connectors of the suspension wires and belts

must be securely linked with those of the speaker.

· All parts and components (such as enclosures,

metal pieces, and screws) must be free from any deformation, crack, and corrosion.

· Be sure to use screws supplied with the optional

flying hardware when installing the speaker using such hardware.

• 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.

When Installing the Unit

• 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 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 in combination. Doing otherwise may cause the unit or component to fall off, resulting 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 install the unit in indoor swimming pools or such locations where corrosion may occur easily. The parts deteriorate if corroded, causing the unit to fall, which could result in personal injury.

• Be sure to read this safety instructions in this section carefully in prior to use.

• 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.

WARNING

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 injury, and/or property damage.

WARNING

CAUTION

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.

• To avoid risks, warn others to stay away from the speaker or not to lean against it. Otherwise people may trip over a Rigging Support Bracket or the speaker may fall down, causing personal injury.

• 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 speaker or the unit that could cause it to fall, possibly causing personal injury.

2. GENERAL DESCRIPTION

3. FEATURES

4. INSTALLATION PRECAUTIONS

TOA's lineup of line array speakers employs TOA's unique wave front control technology to create a sound field that offers clear reproduction and uniform sound dispersion. This lineup includes versions offering either 5 degrees or 15 degrees of angled vertical directivity, as well as sub-woofer configured types. The use of optional support brackets allows the line array speakers to be used in many applications as permanent sound system installations.

• TOA's unique wave front control technology creates a uniform sound distribution field with interference-free high frequency output, realizing high-clarity acoustic characteristics and long sound transmission capabilities.

• The SR-C8L is a two-way speaker mounting a high-power 20 cm woofer and two compression drivers, and featuring a 5 degree angle of vertical directivity and 110 degrees of horizontal. It is ideal for long distance applications and can be powered by either one or two amplifiers.

• The SR-C8S is a two-way speaker mounting a high-power 20 cm woofer and two compression drivers, and featuring a 15 degree angle of vertical directivity and 110 degrees of horizontal. It is ideal for shorter distance applications and can be powered by either one or two amplifiers.

• By combining the long-distance SR-8L and short-distance SR-8S, a line array speaker system can be built to support a variety of applications.

• The SR-C15B sub-woofer employs a large-diameter 38 cm woofer with high power handling capabilities, and is designed to be used in conjunction with the SR-C8L or SR-C8S line array speakers.

• The line array speakers are designed to allow easy rear access for maintenance work.

• Overlap angles between individual speakers can be set in 1 degree units between 0 and 5 degrees when constructing the line array speaker, making it possible to flexibly control speaker directivity.

• The line array speaker can be stacked or suspended with the additional use of the SR-RF8 Rigging Frame.

Since this speaker system is designed exclusively for indoor use, be sure to install it only in locations isolated from weather and temperature extremes. Also, to prevent equipment malfunctions, do not install the speaker in locations exposed to both high temperatures and high humidity, such as indoor swimming pool facilities.

6. BI-AMPLIFIER AND SINGLE-AMPLIFIER OPERATIONS

The SR-C8 series speakers are supplied from the factory set up for bi-amplifier operation. However, this default specification can be switched to single-amplifier operation mode by simply changing the position of an internal connector. (Refer to page 10. "Switching to Single-Amplifier Operation Mode")

7. SWITCHING TO SINGLE-AMPLIFIER OPERATION MODE

To switch the speaker's bi-amplifier operation mode to single-amplifier operation, remove the speaker's rear input panel and change the speaker's internal wiring.

Switching Power Modes

Step 1. Remove the four screws securing the input terminal panel and pull out the panel.

Step 2. Pull out a short length of the wiring connected to the back side of the input panel.

Step 3. Disconnect and switch the two pairs of connected connectors so that the two marked and unmarked

connector halves match up.

Step 4. Reinstall the input terminal panel using the four removed screws.

Step 5. Attach the supplied seals to the input terminal panel to change the indication.
