• 4 x 3500W Power
  • DSP Controlled Powersupply
  • Active PFC for worldwide usage

The AD-Systems K14 is a high output power amplifier, and has been designed to provide that, Powerful Pure Sonic Performance. The new K14 with DSP controlled PFC power supply is a technical highlight, offering up to 14,000 W of undistorted power in an extreme compact and lightweight package.


The development of a DSP controlled, active PFC (Power Factor Correction) enables the K14 to use the mains power supply much more efficiently than before. The PFC makes the immense power of 3,500 W per channel possible and improves the impedance headroom down to 2 Ohms. The PFC provides a solid supply voltage to the amplifier output modules, independently from different or fluctuating mains voltages.

Via a USB connector on the rear, the power supply can be configured to different circuit breaker characteristics and tripping currents. The K14 power supply’s DSP automatically choses the best regulating algorithms for highest power performance for any mains voltage range (100 V, 120 V and 230 V).

Furthermore the K14 introduces new class D amplifier technology offering smooth and responsive handling with massive output power.
