Audac EPA254 Four-channel class D amplifier with a power of 4 x 250 watts and a built-in crossover
4 x 250 Watt Class D Four-Channel Amplifier with Built-in Crossover
Lightweight Class D Amplifier
Energy-star Certified
Energy-saving standby mode
Convection cooling
Euro-terminal speaker outputs
Balanced XLR inputs with crossover switch
Integrated crossover
This energy-efficient four-channel stereo amplifier will automatically switch to standby mode when there is no audio signal (with a consumption of less than 1 watt in standby mode). Its low weight and compact 1U size make it ideal for both fixed and mobile installations. The use of Class D amplifier technology ensures superior efficiency as well as superb sound quality. Thanks to the completely passive cooling system, minimal maintenance is required, ensuring maximum reliability.
This four-channel design allows the use of two separate stereo signals. In combination with the integrated active crossover, the amplifier offers a complete solution for compact stereo applications in combination with a passive subwoofer. Numerous specific functionalities and modern circuitry guarantee optimal protection against overvoltage, overheating and overload. The input terminals are on balanced XLR connections. The speaker outputs are designed with euroterminals.
