2. Importing CAD Drawings (Optional)

Skip this section if you don’t have CAD drawings.

1. Open drawing in CAD application
2. Navigate to:
   ​File → Export → Layout Picture​
3. Select previously saved ​drawing (*.bmp)​​
4. Configure dimensions:
   • Set real-world measurements (e.g., basketball court: 28m × 15m)
   • Establish reference point A at coordinates (0,0) for speaker symmetry

---

3. Creating Audience Zones

1. Click the ​​”Sound Source”​​ icon
2. Select:
   ​ZSOUND→ ZSOUNDLine Array → OK​
3. Position speakers by:
   • Selecting appropriate model
   • Configuring quantity
   • Setting hanging method

---

4. Speaker Placement & Sound Field Optimization

Basic Setup

• ​Copy/Paste Speakers: Use ​Ctrl+C/Ctrl+V​ for symmetrical placement
• ​Add Fill Speakers: Incorporate two VAM speakers as needed

Auto-Alignment

1. Select speakers
2. Click ​​”Auto Splay” → “Start” → “Show Mapping”​​

Adjustment Methods

Based on sound pressure distribution (weaker from stage rear/sides):

• Reposition or rehang speakers
• Modify main speaker:
  • Opening angle
  • Height
  • Quantity
• Add supplemental fill speakers

---

5. Sound Field Verification

Post-adjustment requirements:

• Even sound pressure distribution
• ​Ideal Benchmark:
  • 1kHz frequency
  • 105dB target
  • ±4dB variation across most areas

---

6. Receiver Placement

1. Position testing microphones in audience areas
2. System will:
   • Designate first microphone as reference (0ms delay)
   • Automatically calculate relative delays for other speakers

---

7. Advanced Adjustments

Radiation Angle

• Adjust individually in ​side view​

Speaker Parameters

• In ​top view: Modify gain and delay values

Section Analysis

• Use ​​”Section Plane”​​ to:
  • Move cutting plane
  • Observe sound pressure curves

---

8. Reporting

Generate final documentation:
​File → Create Report → OK → Save​

---

Key Concepts (Brief)

Sound pressure range, bar/linear graphs, and time span parameters affect system performance but require separate technical documentation.

---

Best Practices

1. Always verify real-world measurements match digital models
2. Prioritize even coverage over maximum SPL
3. Document all adjustments for future reference
