• Intermodulation distortion (IMD): Reducing the overlap between audio signals helps to reproduce vocals and instruments more clearly.
• Damping Factor: 800:1 This is a very high value, allowing for excellent control of the speaker diaphragm, especially in the bass range. The bass becomes solid, tight, powerful, and minimizes vibration or trailing distortion.
• Response speed (Slew Rate) 70V/µs: This allows the device to respond quickly to signals with high amplitude and fast tempo, ensuring powerful and accurate sound.
• Using a Class TD circuit: Combining the advantages of high performance and stable sound reproduction, while reducing heat generation during high-power operation.
• Input impedance 20kΩ (Balanced) and 10kΩ (Unbalanced): Easily compatible with digital processors, mixers, and signal processors while ensuring stable signal transmission.
• XLR and TRS connector system: It offers flexible connectivity with a wide range of professional audio devices while minimizing signal loss during transmission.
• Cooling by airflow from front to back: It helps dissipate heat quickly, maintaining stable performance even when operating continuously for many hours.
• Multi-layer protection: It includes Soft Start, DC protection, short-circuit protection, overload protection, Clip Limiter, and over-temperature protection, helping to protect both the amplifier and the speaker system from malfunctions during use.
• Supports Stereo, Parallel, and Bridge modes: Users can select the operating mode that best suits their different audio configurations.
• Integrated HPF, LPF, input sensitivity adjustment, and Ground Lift: It helps optimize signal transmission, reduce noise, and improve compatibility with professional karaoke, auditorium, and stage sound systems.
