• Powerful Output:The B200 is capable of delivering substantial power, with up to200W into both 4 and 8 loads(at less than 1% THD), ensuring it can drive a wide range of demanding speakers.
• NFCA Discrete Amplifier Circuit:It features Topping’s newly developed NFCA (Nested Feedback Composite Amplifier) discrete architecture, which achieves exceptionally low distortion (<0.000075%) and a high dynamic range of145dB, resulting in pristine and detailed sound reproduction.
• Versatile Inputs:The amplifier is equipped with three sets of balancedXLR/6.35mm combo inputs, providing flexibility and compatibility with various audio sources like DACs or preamplifiers.
• Adjustable Gain:Two gain settings (Low: 11.6dBandHigh: 22.0dB) allow users to optimize performance based on their specific speakers and listening environment.
• System Integration:It includes a12V trigger inputinterface, enabling synchronized power on/off with other compatible audio devices for seamless system control.
• Robust and Compact Design:The unit is housed in a sleek, solid aluminum case that provides both durability and effective shielding against interference.
