TOA Electronics Type H Slim Line Array- Long/Straight 0 Degrees- 8/...
The TOA SR-H3L is a slim line array speaker featuring 16 direct-radiating 2.8" (7 cm) cone-type drivers arrayed vertically in a ported MDF enclosure with a narrow 84 mm profile. Using TOA's Sync-Drive technology, it forms a near-ideal linear sound source that reduces acoustic attenuation over distance, suppresses unwanted reflections, and provides high resistance to feedback — making it effective for installations with long reverberation times, narrow corridors, or challenging acoustic conditions.
Rated at 360W continuous program power into 8Ω with 95 dB sensitivity (1W/1m equivalent, measured at 8 m) and 90° horizontal coverage, the SR-H3L delivers clear, well-focused sound to standing and seated audiences in long rooms. The optional DP-SP3 digital processor provides recommended EQ for optimized frequency response (110 Hz–18 kHz). The optional MT-S0301 matching transformer adds 70V and 100V line support for distributed PA systems. Available in white with urethane paint finish; installation accessories include wall tilt, wall mount, flying, stand adapter, and extension plate brackets.
| Feature | Benefit |
|---|---|
| TOA Sync-Drive Technology | Creates an ideal linear sound source — sound attenuates at 3 dB per distance doubling rather than 6 dB, extending coverage in long rooms |
| 84 mm Slim Profile | Fits architecturally in narrow spaces and blends with interior décor without visual intrusion |
| 16× 2.8" Vertical Driver Array | Forms a continuous linear source for consistent, focused coverage over the full speaker height |
| 90° Horizontal Coverage | Delivers wide left-right dispersion for audience areas without overshooting adjacent spaces |
| 0° Vertical Coverage (within speaker height) | Keeps sound in the vertical cylinder in front of the speaker — minimizes ceiling reflections and feedback |
| DP-SP3 Digital Processor Compatibility | Applies optimal EQ preset to maximize frequency response and tonal accuracy |
| MT-S0301 Transformer Compatibility | Supports 100V line (10/30W taps) and 70V line (5/15/30W taps) for distributed PA systems |
| Removable Input Connector | Simplifies wiring and field maintenance with tool-free disconnection |
Typical Applications
The TOA SR-H3L is suited for large auditoriums and concert halls requiring long-throw coverage, airport terminals and transit concourses, hotel ballrooms and conference centers, houses of worship with long reverberant spaces, museum galleries and exhibit halls, school gymnasiums and multipurpose rooms, retail spaces with high ceilings, and courtrooms or council chambers where feedback resistance and speech clarity are priorities.

FAQ
- What is Sync-Drive technology? Sync-Drive is TOA's proprietary driver synchronization technology that creates an ideal linear sound source — sound attenuation is approximately 3 dB per distance doubling (vs. 6 dB for a point source), resulting in more consistent levels across long coverage distances.
- Does the SR-H3L require an external DSP? The optional DP-SP3 Digital Processor is recommended for optimal frequency response, but the speaker can operate without it — at reduced low-frequency extension per the -10 dB spec.
- Can it be used with 70V or 100V distributed PA systems? Yes, with the optional MT-S0301 matching transformer: 100V line supports 10W and 30W taps; 70V line supports 5W, 15W, and 30W taps.
- What is the installation clearance needed? The speaker is 1186.4 mm (46.7") tall and 84 mm (3.3") wide — plan for the full height plus bracket clearance depending on the mounting solution.
- Can multiple SR-H3L units be combined? Yes — stacking SR-H3L units or combining with SR-H3S (short version) extends the vertical height of the line source, further reducing vertical dispersion and extending throw distance.
- What color is available? The SR-H3L is white. Contact your TOA dealer for custom color availability on large projects.
