Key Features
The Topping Pre900 Balanced Preamp is a reference-grade preamplifier for audiophiles and professional systems demanding transparent balanced performance. Its true four-channel balanced architecture processes the signal from input to output using a fully differential design, helping to minimise interference and preserve channel separation. Independent digital and analogue power supplies further reduce internal crosstalk, maintaining a clean background even during demanding playback.
A precision relay-controlled resistor network delivers 1,000 volume steps in 0.1 dB increments, keeping left and right channels accurately matched while maintaining a consistent tonal balance at any listening level. With three Neutrik XLR/TRS balanced combo inputs, you can connect multiple professional sources and switch between them with ease. High dynamic headroom, a safe volume mode, 12V trigger support, a 2.0-inch colour display, and an aluminium CNC remote make the Pre900 a practical addition to high-performance hi-fi and studio systems.
