Professional Power Amplifier

Power Perfected, Sound Elevated
 Slim 1U Design
 External Fuse Box Design
 Ultra-Low Standby Power
 Built-in Overheating Control
 Intelligent Cooling, Low Noise

The Professional Power Amplifier offers a sleek 1U slim design with high functionality. Its ultra-low standby power of 4W and 90% operating efficiency minimize energy wastage. The built-in peak level limiter prevents speaker damage from clipped signals, signaled by a clipping indicator. Overheating control ensures operation under extreme temperatures, compressing signals to prevent shutdowns. Robust protection features include soft start, DC, high-frequency, over/undervoltage, overload, short circuit, peak limiting, and overheating protection. Surge protection on power terminals surpasses EMI standards. The globally compatible PFC power supply reduces grid interference. A smart cooling system balances heat and noise during full power use. The external fuse box design with spare fuses enhances device protection and maintenance convenience.
