Pro-Ject Phono Box RS Phonostage

The Phono Box RS is an ultra-low noise and distortion phono preamplifier for the analog audio purist. It has been designed to deliver breathtaking performance from your phono cartridge through the availability of an unprecedented range of adjustments.

Proper impedance matching is key to great sound and the Phono Box RS provides the ability to continuously vary impedance from 10-1,200 Ohms, even during playback. Top-grade component parts are used throughout the dual-mono circuit, ensuring exceptional quietness and purity of sound.

Unique features include a fully passive selectable RIAA and DECCA phono equalization circuit, full compatibility with MC and MM cartridges via selectable load capacitance and fully balanced inputs and outputs. Heavily shielded chassis metalwork is used to protect against the negative effects of vibration and electrical interference. The Phono Box RS is a high-performance value. Rarely is there a product that delivers such clear, detailed and smooth sound from vinyl records at such a modest price.
