Small Line Array Speaker System for Small Lecture Halls



Ⅰ.  Solution Overview


For small lecture hall scenarios, the core objective of the professional sound reinforcement system is to ensure highly intelligible, distortion-free audio delivery across all seating areas, while mitigating inherent acoustic challenges including reverberation and sound distortion.To reach this target, the system must feature uniform sound field coverage, premium electroacoustic performance, and adaptive compatibility with the venue’s architectural acoustic environment. Targeting these core requirements, this document presents a rigorously engineered, venue-specific solution.



Project Requirements

● Uniform sound coverage: Customized to the lecture hall’s dimensions, the system delivers consistent sound across all areas for a uniform listening experience at every seat.
● High directionality:Precisely controlled sound propagation direction minimizes sound wave reflections and acoustic interference.
● High sound pressure level: Delivers sufficient SPL output to meet the volume requirements of most small lecture halls.
● Minimal reflections and echoes: Significantly reduces sound reflections and echoes to improve speech clarity and intelligibility.

● Ease of use: Supports quick setup with an intuitive interface and full user manual for straightforward daily operation.


 Ⅱ. Small Lecture Hall Configuration 



Small Lecture Hall Configuration

● Small lecture hall: 18m (L) × 7m (W) × 3m (H); rectangular stage with 3m depth and 7m width.
● System components: Microphone system + professional sound reinforcement system.
● System functions: Handheld wireless microphones support mobile audio amplification, with a mixing console for audio source mixing and adjustment. Active line array full-range speakers paired with subwoofers deliver wide sound coverage, suitable for both speech and musical performances.
