The Topping B200 power amplifier is a high-efficiency mono amplifier that uses a discrete NFCA amplifier circuit, designed to deliver impressive power while maintaining outstanding sound quality. It can deliver 200W of power into 4 ohms and 8 ohms, with extremely low distortion (<0.000075%) and a dynamic range of 145dB. The B200's interface is minimalist, with three balanced XLR/6.35mm combo inputs supporting XLR and 3.5mm connectors, and a speaker output. A two-stage gain control (11.6dB low gain, 22.0dB high gain) allows the amplifier to be adapted to different speakers and configurations. Housed in a sleek aluminum housing, the B200 also features a 12V trigger for seamless integration with your Hi-Fi system, automatically turning on when the system is activated.
