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 withstand the speaker

load.

· 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.

• 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.

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

• 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.

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 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.

• 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.

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-C8LWP 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-C8SWP 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-8LWP and short-distance SR-8SWP, a line array speaker system can be

built to support a variety of applications.

• The SR-C15BWP 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-C8LWP or SR-C8SWP 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 suspended with the additional use of the SR-RF8WP Rigging Frame.

The WP series is a splash-proof speaker, however please be sure to install it under a roof or eaves or in other

locations where the speaker is not directly exposed to rain or snow. Also, avoid installing the speaker in such

high-temperature and high-humidity locations as swimming pool facilities. Failure to follow these instructions

could lead to equipment malfunctions.

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 9. "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.
