Design Concept of the New Line Array System:

1.   System Composition and Hanging Frame

   - The line array consists of dual-15 ", dual-12 ", and dual-10 " line array with a uniform width of 1.2 meters, featuring identical hanging points for flexible configuration.

   - Utilizes a classic three-point hanging mechanism for seamless integration with 1.2m dual-18 " or dual-21 " bandpass subwoofers.- The lightweight hanging frame allows for single-person operation.

2.   Coverage Distance and Dispersion Angles

Dual-15 " :

- High-frequency dispersion: 60(wider angles may cause interference with adjacent units).- Projection range: 50 –80 meters, optimized for far-field coverage .

Dual-12 " :

- High-frequency dispersion: 80° .

- Projection range: 30 –50 meters, designed for mid-field coverage .

Dual-10 " :

- High-frequency dispersion: 100°.

-   Projection   range:   <30   meters,   with   wider   angles   ensuring   uniform   near-field coverage .

3.   Advantages Over Multi-Way Line Arrays

   Traditional multi-way line arrays require manual EQ adjustments (e.g., high-frequency compensation) for far/mid/near-field coverage— a technically demanding process often leading to suboptimal results.

Our   solution:   Pre-configured   DSP   settings   in   amplifiers   with   dedicated high-frequency compensation:

- Dual-15 ": +12dB for far-field.

- Dual-12 ": +9dB for mid-field.

- Dual-10 ": +6dB for near-field.

( Simplified wiring and reduced user learning curve).

4.    Extended Low-Frequency Response & Deployment Guidelines

-    Low-frequency extension : 40Hz (vs. conventional 60-70Hz), with phase alignment to prevent inter-array interference.

Deploymentrecommendations:

   5,000 attendees : 8 Line arrays (e.g., 2 ×   dual-15 ", 4 ×   dual-12 ", 2 ×   dual-10 ").10,000 attendees : 16 Line arrays(e.g., 8 ×   dual-15 ", 4 ×   dual-12 ", 4 ×   dual-10 ").20,000 attendees : 24 Line arrays(e.g., 12 ×   dual-15 ", 8 ×   dual-12 ", 4 ×   dual-10 "). Scalable for larger events (30,000+ attendees) ...

-     For   smaller   attendees,   the   dual-15 "   line   array   may   be   omitted,   utilizing   only dual-12 " and dual-10 " units instead.

5.   Standalone Usage Considerations

-    Recommended : Dual-12 " or dual-10 " for standalone setups.-    Dual-15 " not recommended alone due to its narrow vertical dispersion, requiring precise alignment to avoid coverage gaps.

6.    Upgraded Horn Design

-    Enhanced horn length for improved 10kHz high-frequency energy.

-    Driver configurations :

     - Dual-15 ": 3 ×   3 " HF drivers.

     - Dual-12 ": 2 ×   3 " HF drivers.

     - Dual-10 ": 2 ×   2 " HF drivers.
