The table of five cast delivers a compact yet powerful staging configuration for live audio and rehearsal environments. This setup balances clarity, coverage, and cost efficiency, making it a common choice for touring engineers and venue operators.
Designed around five primary loudspeakers, this layout helps achieve consistent level, coherent time alignment, and controlled dispersion across varied stage shapes.
| Model | Type | Frequency Range | Max SPL | Recommended Use |
|---|---|---|---|---|
| L1 | Line Array Module | 82 Hz – 16 kHz | 123 dB | Front-of-house speech and music |
| L2 | Line Array Module | 82 Hz – 16 kHz | 122 dB | Front-of-house speech and music |
| S1 | Subwoofer | 48 Hz – 1.2 kHz | 120 dB | Low-frequency reinforcement |
| US1 | Ultra Sub | 38 Hz – 400 Hz | 125 dB | Bass extension and fill |
| AD-S8 | Array Processor | 20 Hz – 20 kHz | n/a | Control, time alignment, limiting |
Core Coverage and Placement
In a table of five cast, the left and right mains typically consist of line array modules oriented for wide, even coverage. A center module can focus on the stage or audience midpoint, while subs flank the array to manage low-frequency energy without excessive stage stack size.
System Alignment and Timing
Time alignment across the five elements is managed by the array processor, which corrects phase and delay between tops and subs. Proper alignment minimizes comb filtering and ensures the sound arrives at the listener as a coherent wavefront.
Scalability and Expansion Options
The table of five cast can be augmented with additional fill positions or rear surrounds. Scaling maintains the core concept while adapting to larger venues, using the same line source modules and centralized control architecture.
Coverage and Pattern Control
Vertical coverage is shaped by each line source module, while array curvature and hanging angle tune horizontal dispersion. This flexibility supports both flat stages and multi-level seating without physical repositioning of every loudspeaker.
Reliability and Operational Practices
Consistent rigging, periodic system checks, and documented preset management keep performance predictable across tours and venues. This disciplined approach supports long-term reliability and audience satisfaction.
- Verify line source curvature and vertical angle before each show
- Confirm sub and ultra sub crossover points with real-time spectrum analysis
- Back up array processor scenes and document alignment notes
- Monitor amplifier temperature and limiters during extended events
FAQ
Reader questions
How does hanging height affect intelligibility in a table of five cast setup?
Higher speakers reduce early reflections from the stage, improving direct-to-reverberant ratio. However, excessive height can narrow off-axis coverage if rigging limits tilt adjustment.
Can this layout handle both speech and full-range music equally well?
Yes, when the array processor is configured with multiple presets. Speech benefits from controlled dispersion, while music presets widen stereo image and emphasize mid-high detail.
What role does the array processor play in system calibration? The processor applies EQ, delay, and limiting per channel, aligning magnitude and phase across drivers. Room measurements drive target curves that protect transducers and optimize tonal balance. Is active crossover integration required for sub and ultra sub pairing?
Integrated crossovers prevent overlapping energy and reduce amplifier demand on low frequencies. Setting slope and alignment frequency based on venue volume and ceiling height preserves headroom and clarity.
