Description
The Citronic 172.125UK Hybrid Class-H Power Amplifier is engineered for professional sound reinforcement in demanding environments. Built into a 2U 19″ rack-mount chassis, this amplifier features a hybrid Class-H circuit that blends the efficiency of digital control with the punch and reliability of analogue output power.
With selectable stereo, bridge, and parallel modes, and a switchable 120Hz low-pass filter for subwoofer integration, the H-series amp provides versatile configuration options without requiring extra rack gear. A backlit LCD display continuously reports on supply voltage, temperature, and output level, helping technicians monitor performance in real-time.
This amplifier is stable down to 2 Ohms, offering robust output for high-demand applications like live venues, mobile DJs, and installed PA systems. Internal protection circuitry guards against overheating, overloading, and startup surges, while balanced XLR inputs with selectable sensitivity levels ensure compatibility with a wide range of mixers and processors.
