KA
The newly developed high-efficiency D-class amplifier combined with an analog ring transformer power supply has the characteristics of low energy consumption, good sound quality, and safety and reliability.
Key Features
• High quality professional amplifier, delivering clean and delicate sound performance
• KA600, The KA800 low-power amplifier adopts a switch mode power supply design, with high detail and open sound. The KA1200 and KA1800 high-power amplifiers adopt advanced loop conversion circuits, with warm and powerful sound, especially the high-power subwoofer, which is full of dynamic and dynamic feel
• Adopting a highly reliable power supply design, it has undergone extensive stability testing and rigorous condition testing to ensure continuous use at full power output
• Large capacity energy storage capacitors provide delicate and consistent sound performance during continuous high dynamic output
• A brand new heat dissipation structure design, which disperses the components that are prone to heat generation, and is equipped with high-power heat dissipation fans and straight through heat dissipation channels, further improving the stability of the power amplifier and ensuring long-term full load use without any problems
• Specially designed high current short circuit protection design ensures that the amplifier will not output signals through DC, protecting the rear speaker system
• Equipped with three-level sensitivity adjustment of 0.775V, 1V, and 1.4V, the power amplifier can be used for both karaoke systems and professional sound reinforcement systems directly
• Perfect protection functions, including load short circuit protection, DC output protection, high temperature protection, voltage undervoltage protection, etc
• The minimalist and fashionable exterior design showcases the characteristics of high-quality amplifiers
