Design and operating principle
The transducer is a compression driver. The horn shapes a directional output (coverage angle 60° horizontal × 30° vertical) and delivers high sensitivity of 115 dB; SPL is 140 dB continuous / 143 dB peak. Frequency range is 120 Hz – 12 kHz.
An IP66 ingress protection rating and an operating temperature range of −40 °C to +70 °C are engineered for year-round outdoor operation. Effective announcement range is up to 300 m, STIPA speech intelligibility index 0.8, and wind resistance of at least 12 on the Beaufort scale.
Warranty and certification
- EAC certificate of conformity
