The TOA SR-H2L is engineered for AV integrators and system designers who need consistent, controlled audio distribution across large indoor spaces without sacrificing architectural aesthetics. Its 84mm slim profile is purpose-built for venues where speaker visibility is a concern, including houses of worship, conference centers, lecture halls, and hospitality spaces. The vertical array of internal speaker components forms a true linear sound source, enabling coherent wavefront behavior that reduces reflections and maintains intelligibility across the listening area. Sync-Drive technology allows multiple SR-H2L units to be linked together for beamforming and beam-steering capability, giving system designers precise control over vertical coverage and sound projection. When paired with the optional DP-SP3 DSP unit, frequency response is optimized to extend low-end performance and shape the array's directivity for the specific room. For high-impedance distributed audio systems, the optional MT-S0301 matching transformer makes the SR-H2L compatible with 70V and 100V line topologies, broadening its applicability in larger installed systems. The combination of narrow directivity, low coloration over distance, and a clean white MDF enclosure makes this line array module a practical choice where both sonic performance and visual integration matter.
