The Pro-Ject Amp Box RS power amplifier is a stereo model with a fully balanced dual-mono circuit design and Pulse Width Modulation. It features a tube preamp stage, line-level RCA and XLR inputs, and can drive speakers with an impedance of 2 Ω. Power conversion from the mains to the output is 92% efficient.
SMD construction helps keep signal paths short, while the metal enclosure reduces vibration and interference. Its low heat output complements the design.
