High-Efficiency Class D Concept: Provides 1 x 250 W of power at 100 V with an impressive efficiency of over 90%, leading to considerable electricity savings compared to traditional analog amplifiers.
Silent, Fanless Operation: The low thermal loss of the Class D design allows for a fanless cooling concept, ensuring silent operation—ideal for sensitive acoustic areas.
Automatic Standby Mode: Features an integrated energy-saving function that automatically switches to standby when no input signal is detected, and reactivates instantly upon signal return.
Dual Power Operation: Supports both mains operation (230 V/ 50 Hz) and 24 V emergency power operation, ensuring continuous functionality for critical applications like emergency announcements.
Priority Input: An additional priority input allows for the seamless integration of emergency announcements or priority messages.
