Description
Capable of delivering 1800 watts per channel into either a 2 or 4 ohm load, Yorkville Sound's new AudioPro AP4K uses proven Class-H technology and advanced protection circuitry to provide unmatched long term reliability in the field.
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.
