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. 4. INSTALLING THE SR-F1D ON THE SR-L1B • When one SR-F1D is installed on the SR-L1B • When two SR-F1Ds are installed on the SR-L1B Align with the front surface of the SR-L1B. SR-F1D SR-L1B SR-F1D SR-L1B 5 5. FLYING (SR-F1D ONLY) Two flying methods can be performed: 1) direct suspension using the SR-F1D's flying hardware (refer to the figures below), and 2) suspension using optional flying hardware (refer to p. 7). WARNING • Be sure to refer flying construction work to the dealer from whom the speaker was purchased. • Avoid flying methods other than those described in this section. Otherwise, the suspension wires or belts may be off or snap and the speaker may fall off, causing personal injury. 5.1. Direct Suspension Using the SR-F1D's Flying Hardware Shown below are the general flying methods: SR-F1D's flying hardware • Use the pan fitting rings attached to the speaker's top and/or bottom. • Provide at least two suspension points on each speaker's top. • The maximum number of speakers that can be suspended vertically is three. Do not suspend as illustrated below: 6 • Use of a single wire that has formed a loop • Flying through only one suspension point on the top. • Flying through handles. • Flying using the nuts on the bottom surface • Vertical suspension of 4 or more speakers. 5.2. Suspension Using Optional Flying Hardware 5.2.1. SR-F1D speaker flying hardware system The speaker flying hardware system is manufactured by ATM FLY-WARETM (ATM GROUP, Inc.) of the United States for use with TOA's SR-F1D speaker.
