Product details

The Fosi Audio ZA3 mini amplifier offers both stereo and mono modes, flexibly adapting to your diverse needs and allowing seamless mode switching. In stereo mode, it delivers a robust output of up to 180 W, while in mono mode the output increases to a maximum of 235 W. Pair two ZA3 units in mono configuration to create a powerful audio system that significantly enhances your listening experience. The ZA3 features a balanced combo audio signal input connector that supports both XLR and 1/4-inch TRS plugs. This design minimises interference and reduces noise. The 12V trigger-in connector allows synchronisation with other devices, streamlining the process of switching on and off without individual operations. The ZA3 features the TPA3255 high-end class D amplifier chip and utilises high-quality Japanese NCC, ELNA and German WIMA capacitors.
