About: Deaf Bonce AAK-220.4 Apocalypse Series 1280W RMS 4-Channel Amplifier 

Non-compromising power! Amazing specifications and extreme power performance. The upgraded amplifier circuitry, the updated management of the key mosfet transistors, and increased voltage in the power supply unit allowed to increase the output power by 15%.

Equally high efficiency in the entire range of operating voltage - from 9 to 15 volts, gives a wide application in competition level SPL systems. Bridge mode allows you to double the output power.

Reliable four-level protection system provides high-level protection against overheating, overload, short circuit and direct current. In addition to adjusting the gain level, the remote controller is equipped with all the necessary indicators for maximum control over the audio system.
