### **The Physical Setup:**
- Uses a **metal plate** (0.62 x 0.91 m) as the resonant medium
- Two **electroacoustic transducers** (4-inch speakers) mounted on the plate:
- One as "**plate nozzle**" (output/actuator)
- One as "**plate collector**" (input/pickup)
- **Automatic Gain Control (AGC)** - crucial component for sustaining feedback
- **Variable resistor** for real-time loop gain control
- **External amplifier and speaker** for monitoring
