1. SAFETY PRECAUTIONS • Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation. • Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety. • After reading, keep this manual handy for future reference.
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 • Avoid touching the unit's sharp metal edge to prevent injury. • Do not use anti-rust lubricant. If the unit contains resin parts, they could deteriorate and cause the parts to fall, possibly resulting in personal injury.
2. GENERAL DESCRIPTION The line array speaker features slim 84 mm (3.3")-wide construction incorporating high-quality 7 cm (2.8") fullrange speaker units. The internal speaker units are vertically arrayed in close proximity to form an extended sound source line, minimizing distance attenuation and realizing a uniform sound pressure coverage area.
4. ABOUT COVERAGE AREA The line array speaker radiates a sound only within a limited range as shown below. Since sound is extremely reduced in areas that are outside the range, take care that the listening area is sufficiently covered when installing the speaker. Installation examples [SR-H2L] [SR-H2S] [SR-H3L] [SR-H3S] [SR-H3L x 2] Tips • Installing the line array speaker in a lower position with a narrow downward angle allows a wider coverage area to be secured from front to rear.

6. INTERNAL WIRING DIAGRAM When shipped from the factory, the speaker is internally connected as shown below. Since two pairs of “+” and “–” input terminals are parallel-connected internally, they can be used for parallel connection to a second speaker. 6.1.

7. INPUT TERMINAL CONNECTION Removable input connector offers easier and more efficient wiring. Socket Removable terminal plug 1 5 mm (0.2") 3 2 Speaker cable Speaker body (rear) Tip The 12 mm (0.47")-high ridges in the back of the speaker provide ample space for speaker wiring. Even when the speaker is mounted flat against a wall, the speaker cable outlet hole in the wall does not need to be aligned with the input terminal position. Wall 12 mm (0.
8. CHANGING TO HIGH IMPEDANCE The speakers can be used for high-impedance applications with the installation of the optional MT-S0301 Matching Transformer. Even after the matching transformer has been installed, the removable input connector is used in the same manner as for low impedance operation. To install the MT-S0301 transformer, remove the blank panel located on the speaker's rear surface.
9. JOINING SPEAKERS Two linear speakers can be linked to each other using the optional SR-EP3 Extension plate. Joining line array speakers configures a longer linear sound source, permitting transmission of higher sound output over a longer distance. Notes • Linkage is only possible for the following two speaker combinations, and cannot be performed for any other combinations: SR-H3L + SR-H3L SR-H3L + SR-H2L • When linking, position the lower speaker upside down. Step 1.
10. INSTALLATION EXAMPLES USING THE OPTIONAL BRACKETS The optional mounting brackets are intended exclusively for the line array speakers and permit installations suited to the installation location or application. For mounting method, please refer to the installation manual enclosed with each bracket.
11. 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. 11.1.
