An impedance mode switch on the back panel of the amplifier allows the user to select full output power into either a two or four ohm load for maximum application flexibility. This means this compact two rack space amplifier can deliver up to 3600 watts of clean, pure power into either 4 or 8 ohm loads (bridged), making it a perfect solution for virtually any touring live sound, club system or installation.

The internal signal path has been optimized and a toroidal transformer is used in the AP4K design – both serving to reduce hum and noise in practical real-world applications. It’s three-tier Class-H design approaches efficiency normally associated with Class-D technology; yet provides the superior transient response and low distortion of the best analog designs.
