INSTRUCTION MANUAL

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 so you are thoroughly aware of the potential safety hazards as well as understand the safety symbols and messages.

WARNING Indicates a potentially hazardous

situation which, 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.

When Installing the Unit

• 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 speaker falling down and causing personal injury and/or property damage.

• Flying Precautions (SR-F3 only) Be sure to follow the instructions below. The suspension wires or belts may be off or snap and the speaker may fall, causing personal injuries.

· 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.

When Installing the Unit

• Install a speaker only in stable locations, and make appropriate arrangements to prevent it from falling down or rolling cross the floor. If it falls down or moves, this may cause personal injury and/or property damage.

• When unpacking or moving a heavy speaker, be sure to handle the unit with two or more persons. Falling or dropping the speaker may cause personal injury and/or

property damage.

When the Unit is in Use

• Do not stand or sit on, nor hang down from the speaker as this may cause it to fall down or drop, resulting in personal injury and/or property damage.

• Do not operate the speaker 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.

FEATURES

• The SR-F3 is a two-way full-range dual-amp-driven speaker system, and the SR-L3 is a sub-woofer system. Both systems feature a high power handling capacity, high sound quality, and heavy-duty construction suited to both mobile and permanent installation applications.

• Both speaker systems are designed to be used in conjunction with the dedicated controller.

• The SR-F3 houses a constant directivity (CD) horn that assures a uniform sound dispersion pattern of 60° horizontal by 30° vertical.

• The SR-F3 is equipped with a front-loaded horn with two 30 cm woofers.

• The SR-L3 employs two 46 cm woofers with a long voice coil.

• The SR-F3 has flying hardware (Aeroquip's ring/stud pan fitting) on both the top and the bottom, and an M16 nut on the

sides for attachment of an eye bolt.

• A light-weight, strong coniferous plywood enclosure is finished with extremely-durable epoxy paint.

• Input connectors are Nuetrik's NL4MPR and screw terminals. The SR-F3 is equipped with two Nuetrik connectors to

facilitate parallel connection.

• A woofer baffle is designed to permit easy woofer replacement without having to lay the speaker.

INPUT CONNECTORS

Each speaker's input connectors are as follows. Connections can be made from any connector because all connectors are internally connected in parallel to each other.

5. FLYING

Be sure to consult an installer as to the following uses:

5.1 When using the flying hardware on the top or the bottom of the speaker.

Shown below are the general flying methods:

[Precautions]

• Provide at least two suspension points on each speaker.

• The maximum number of speakers that can be suspended

vertically is three.

Do not suspend as illustrated below:

• Flying through only one suspension point.

• Flying through handles.

• Vertical suspension of

more than 3 speakers.

5.2 When using the nuts on the sides.

For an M16 nut provided on the sides, use an eye bolt with the threaded section of 35-50 mm in length.
