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.

2. 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.

3. 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.
