Product Description

K series digital power amplifier has very strong performance, the total output power reaches more than 10000W, and only needs the installation space of 1U rack. It is one of the most powerful and advanced power amplifier products on the market.

The efficiency is over 97%, and the calorific value is low, which means that it has stable and reliable performance and is more durable.

With extremely wide power adaptability, built-in 20000 W power regulator, it can adapt to the worst power supply environment, thoroughly solve the problem of voltage instability in remote areas.

We have carefully selected all kinds of top-level components. Each power amplifier has more than 4000 components. A large number of original imported raw materials are used, such as Fairchild, ON Semiconductor, Infineon, TDK, and STMicroelectronics. We have selected chips of HiFi Class to get unbelievable sound.

The protection circuit of each channel is independent, even if one channel can not work, it will not affect other channels, providing higher protection for each performance.

Each power amplifier has passed more than 100 full range tests of AP (AudioPrecison) System to ensure that each power amplifier achieves the most ideal parameters and performance, and maintains the high consistency of products.

It is a perfect choice for places that need relatively high continuous power and high requirements. It pays attention to the timbre, and is highly efficient. At the same time, it also achieves good stability, portability and adaptability. K series power amplifier is the first choice for the first-class system designer, sound engineer and system technician to provide the most reliable and highest level power and dynamic margin in the smallest possible size.
