RK-A2800
This unit utilizes Class AB topology circuit technology, offering high-efficiency power conversion and exquisite circuit layout.
It features an ultra-high power toroidal power transformer design produced with imported core materials, and is equipped with a 10000μF ultra-high capacity electrolytic capacitor to provide the amplifier with stable and sufficient energy, ensuring continuous power output and high power density.
The cooling is highly efficient, with an internal air guidance system that runs from front to back, and the fan speed increases automatically with the rise in internal temperature to enhance heat dissipation.
Comprehensive protection features include: soft start, direct current protection, overheating and overload protection, anti-impact, and limiting.
The front panel is equipped with precise volume control knobs, and has indicator lights for fault, clipping, signal, and power status.
