Product Description

Pro-Ject Pre Box RS preamplifier is a fully balanced dual mono design with valves in the output stage - a perfect miniature preamplifier for the Pro-Ject Amp Box RS or any other power amplifier, it is available in black or silver.


This preamp is designed to perform input switching and deliver high-performance audio preamplification. The casing is exceptionally rigid and provides no global feedback with protection against vibrations. The pure 'Class A' operation and Low ESR Capacitors associated with the Pre Box RS eliminates any distortion giving you a high-quality signal for your sound system.

Pre Box RS comes with a handy IR remote control for alternating between inputs and volume adjustments.

When coupled with the Amp Box RS the Pre Box RS delivers a true, comprehensive audio sound.
