Page 5: General Description
2. GENERAL DESCRIPTION The line array speaker features slim 84 mm (3.3")-wide construction incorporating high-quality 7 cm (2.8") full- range 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. The line array speaker lineup includes the following four models: •... -
Page 6: About 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]... -

7. INPUT TERMINAL CONNECTION Removable input connector offers easier and more efficient wiring. Socket Removable terminal plug 5 mm (0.2") Speaker cable Speaker body (rear) Wall 12 mm The 12 mm (0.47")-high ridges in the back of the speaker (0.47") provide ample space for speaker wiring. -
Page 11: Changing To High Impedance
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. -
Page 12: Joining Speakers
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... -
