Page 15: Short Circuit Protection
THERMAL PROTECTION - Dual 2-speed fans on the amplifiers A series provide adequate cooling. During low level output the fans run at normal speeds. During high output and as heat raises, (exceeding 50°C.), the fans will run at higher speeds to aid the cooling process. If the heatsink temperature exceeds 91°C., the amplifier will mute until the amplifier cools down. - Page 16 UNiKA A-2000/A-3000/A-4000 Protection Features Introduction Front Panel Rear Panels Set Up Speakon Assembly Operating Modes Specifications INPUT/OUTPUT PROTECTION - The input circuits are isolated by resistors. An ultrasonic network uncouples RF from the output and helps to keep the amplifier stable with reactive loads.
