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.

Power Supply Unit

The advanced switching mode power supply technology, which is applicable in the world, makes the equipment have high performance and small size.

The power factor correction technology achieves extremely low power consumption and wide power operation range. The maximum power factor is 0.99, and the power supply working range is 90v-270v. Suit to different power supply from all most of countries.

Full bridge switching power supply topology, strong current conversion ability, more stable and reliable

Soft start of power supply, strong anti surge ability, realize safe startup in real sense

Power short circuit protection, and EMC (Electromagnetic Compatibility)

Dual thermal protection of power supply, overload intelligent modulation of power, to make the power supply in the most secure state.

Audio Amplifier Components

Fixed frequency switch mode, to achieve high-quality sound accuracy.

3 groups of closed-loop gain loop control, to get extremely fast transient response, smooth frequency response.

Each channel circuit is independent and does not affect each other.

The core module is protected from corrosion, moisture and dust

Hi-Fi grade chip, producing unique sound quality

Comprehensive Protection Design:

AC protection: when the AC power supply voltage exceeds the operating range, turn off the power supply.

Clipping limiter: to prevent the waveform of severe clipping from reaching the loudspeaker while still maintaining the full peak power.

DC protection: prevent infrasonic signal from reaching the loudspeaker at the output end

Over high frequency protection: prevent the strong but not music high frequency signal from reaching the loudspeaker.

Short circuit protection: automatic protection reset function to prevent power amplifier from short circuit or other stress failure

Long term limiter: prevents stable long-term RMS (non audio) signals from reaching the speaker, reducing the maximum output

Thermal protection: the maximum working temperature of output stage and power supply is 75

Temperature controlled continuous variable speed fan, front to back tunnel cooling system

Temperature warning: when the temperature reaches 70 , the LCD screen will give an early warning, the Yellow temperature light will be on, and the output power will be compressed according to the temperature variable until the overheating warning is removed, so that the power amplifier will not have no sound after overheating protection

Switch on / off mute: to prevent impact sound when power amplifier is on / off

Overload protection: prevent current overload damage of components

Signal line hot plug protection: prevent the power amplifier from damage by high surge of hot swapping input XLR when the power amplifier is on.
