describe

The amplifier boasts a sleek and aesthetically pleasing design, a robust and secure structure, and a professional, high-tech image.
It features multiple high-capacity DC power supply systems, ensuring stable DC voltage and powerful amplifier output. All components are carefully selected, matched, and meticulously manufactured to guarantee a wide dynamic range, clear layering, a broad soundstage, and sweet sound quality.
The amplifier extensively utilizes surface-mount (SMD) components, minimizing circuit transmission distances, eliminating interference, and enhancing audio performance. This also significantly reduces manual intervention, ensuring greater product reliability and long-term stability.
The power supply section incorporates excellent power factor correction, eliminating harmful harmonic currents and meeting the power factor requirements of European and American electrical industries.
This series of amplifiers features a sensitive overheat management system. It employs a unique real-time monitoring system to regulate the amplifier's temperature. When the condition threatens operation, it reduces output power without shutting down the circuit. Once the external factor is eliminated, the equipment automatically recovers, ensuring normal operation even in harsh high-temperature environments.
This machine features a fully intelligent protection system, ensuring the stable and reliable operation of the sound reinforcement system and guaranteeing a smooth and peaceful performance.
Suitable for karaoke bars, pubs, nightclubs, multi-purpose halls, and other similar venues.
