Indicates a potentially hazardous situation which, if mishandled, could CAUTION result in moderate or minor personal injury, and/or property damage. When Installing the Unit • Avoid placing the unit in a doorway or other high traffic area as people may trip on the equipment and cords, or be injured by falling objects.
2. GENERAL DESCRIPTION The Mechanically Steerable Line Array Speaker System consists of the SR-MF1(B/W) [Mechanically Steerable Array Speaker] and the SR-ML1(B/W) [Low Frequency Expand Speaker]. A single SR-MF1(B/W) or combination systems with SR-ML1(B/W) can be used. The key feature is that the tilt and dispersion angles of the SR-MF1(B/W) are mechanically and manually adjustable.
4. ANGLE ADJUSTMENT Shifting the angle adjustment bolts mounted on both side of SR- MF1(B/W) allows adjusting its tilt and dispersion angle by multiple steps. [Adjustment Procedure] Step 1. Remove the hex head bolts on both side of the cabinet for releasing the angle adjustment component.
5. COVERAGE AREA The line array speaker radiates a sound only within a limited range. Since sound is reduced in areas that are outside the range, take care that the listening area is sufficiently covered when installing the speaker. • Installation example Coverage of 2”(5cm) drivers Tilt 0°...
6. AMPLIFIER CONFIGURATIONS The Mechanically Steerable Line Array Speaker System can be driven by multiple types of amplifier configurations. • Single-amplifier drive (1 SR-MF1(B/W)) Mixer/Preamplifier Digital Processor Power Amplifier * Load impedance for the amplifier • Single-amplifier drive (1 SR-MF1(B/W) and 1 SR-ML1(B/W)) Mixer/Preamplifier Digital Processor Power Amplifier...

• Single-amplifier drive (1 SR-MF1(B/W) and 2 SR-ML1(B/W)s) Mixer/Preamplifier Digital Processor Power Amplifier * Load impedance for the amplifier • Bi-amplifier drive (1 SR-MF1(B/W) and 1 SR-ML1(B/W)) Mixer/Preamplifier Digital Processor Power Amplifier * Load impedance for the amplifier...
• Bi-amplifier drive (1 SR-MF1(B/W) and 2 SR-ML1(B/W)s) Mixer/Preamplifier Digital Processor Power Amplifier * Load impedance for the amplifier 7. JOINING SPEAKERS To join the speakers, use the expansion plates supplied with the SR-ML1(B/W). [Joining procedure] Step 1. Remove the truss head screws on both side of the cabinet.

8. INSTALLATIONS The optional mounting brackets are intended exclusively for the Mechanically Steerable Line Array Speaker System and permits installations suited to the installation location or applications. Installation Location Application Bracket Flat against the wall SR-MB1(B/W) Wall When adjusting horizontal angle up to 90 ° SR-PB1(B/W) Ceiling When suspending from a ceiling...
8.3. Wall mounting (using the SR-PB1(B/W)) Step 1. Install the bracket bases at the desired positions on the wall. Step 2. Attach the panning brackets on the bracket bases with the supplied screws. Step 3. Hook the speaker on the bracket bases. Slide down the speaker body so that each speaker bracket's hook fits in the bracket base's slit.
8.4. Ceiling-suspended mounting (using the SR-HB1(B/W)) Step 1. Attach the supplied eyebolts and nuts on two screw holes of the bracket as shown below. Step 2. Remove the truss head screws on both side of the cabinet. Step 3. Slide the SR-HB1(B/W) hoisting bracket down on the top of the cabinet, and fix the bracket with the supplied M5 machine screws.
9. DIGITAL PROCESSOR FILTERING Although the speaker can be operated without a digital processor, it is recommended that the speaker be used in conjunction with a digital processor for better sound reproduction. Recommended setting parameters are as follows. 9.1. Single-Amplifier Drive with 1 SR-MF1(B/W) and 1 SR-ML1(B/W) Filter Model Gain...
