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.

• 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.

• 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.

• Cautions when using the speaker stand

Be sure to carefully observe the following instructions. Ignoring them could result in the speaker system toppling over or falling down, possibly resulting in personal injury.

· Open the stand legs to their full extension.

· Do not extend or fold the tripod while the speaker

is mounted.

· Install the stand on a flat, hard surface.

· Avoid placing the speaker in a doorway or other

high-traffic area where people may trip over the equipment or cords.

· In outdoor installations, take such measures as

securing speakers with safety wire to prevent them from being toppled over due to strong wind, etc.

1. SAFETY PRECAUTIONS

• Be sure to read the instructions in this section carefully before use.

• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages regarded as very important precautions are included.

• We also recommend you keep this instruction 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 personal injury, and/or property damage.

WARNING

CAUTION

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.

When the Unit is in Use

• 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 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.

CAUTION

2. GENERAL DESCRIPTION

Developed for the mobile sound reinforcement applications, TOA's SR-F1D and SR-L1B make up a speaker and subwoofer system which features high power handling capability, high quality and durable construction.

3. FEATURES

• The SR-F1D can reproduce both low and high frequencies (bi-amp operation), while the SR-L1B clearly reproduces super-low frequencies. Both systems are used in conjunction with the DP-0206 Digital Processor.

• The SR-F1D reproduces low frequencies with excellent transient response thanks to its high-efficiency 30 cm woofer with large 20 cm diameter magnet.

• The SR-F1D's driver employs a titanium diaphragm and features high sound quality and high power handling capability. Its constant directivity horn (60° horizontal x 40° vertical) has a smoothed cross-sectional area and provides a uniform sound field and smooth sound quality.

• The SR-L1B's 38 cm woofer consists of a strong magnetic circuit employing a large 20 cm diameter magnet and a 72 mm diameter long voice coil. This combination permits ultra-linearity down to super-low frequencies while realizing high power handling capability.

• The enclosure is constructed of high-strength Apiton plywood. Since the outside surface is covered in FRP (glass fiber-reinforced plastic), the speaker also features high durability to stand up to rough handling when used on the road.

• NEUTRIK NL4MPR input connectors ensure quick and accurate system field installations.

• The SR-F1D features flying hardware (Aeroquip ring/stud pan fittings) installed on its top and bottom. The bottom surface is also equipped with built-in nuts for mounting on an optional stand.

• Because the sides of the SR-F1D's enclosure are angled at 15°, when multiple speakers are arranged sideby-side, they can be oriented in a radial array, which helps suppress mutual interference at high frequencies.
