Stereo Box S

This compact integrated stereo amplifier achieves both a sound quality and SPL output that belies its small size. Designed around a Bi-Phase PWM (Pulse-Width Modulation) digital amplifier circuit, the Stereo Box S achieves a remarkable 80% operational efficiency and a highly dynamic 30 watts per channel output into 4 ohms. The shielded metal chassis protects the circuitry from vibration and electromagnetic interference for the highest fidelity possible. A remote control adjusts volume and can switch inputs.

High Notes

Tiny But Robust

A tiny integrated amp that fits in the palm of your hand for when space is tight.

Shielded Vibration Resistant Chassis

Reduces external electrical interference from affecting your sound.

Great Pair with a Phono Box

The size perfectly matches many of the Pro-Ject phono boxes for pairing up when space is very tight left to right.

Pro-Ject Stereo Box S is a combination of Amp Box Stereo and Pre Box, in one case. The new S-styling makes Stereo Box S a timeless looking and elegant device. A record output is also included, which gives the opportunity to use Stereo Box S with other components like Head Box, as described underneath! Outstanding sound quality!
