Product Description

Product Information

Pro-ject Amp Box Stereo Power Amplifier

The Pro-Ject Box Design Amp Box S is an ultra-compact power amplifier, which is both efficient and audiophile. Boasting an impressive 30 Watt output, this small but perfectly formed box will boost any small hi-fi system.

A ultra-high-efficiency, Bi-Phase PWM (Pulse Wave Modulation) circuit with SMD parts gives outstanding audio performance and stays cool on the outside when in use. The sound quality from the Amp Box S is aimed to be as close as possible to Class A tube amplifiers, with their liquid and life-like presentation.

The Amp Box S is micro-sized, allowing for easy placement in any environment. It can also be remotely switched off via a trigger signal (a 45cm power-on cable is supplied for this purpose) for convenient operation. When bi- or tri-amping, this remote power signal can also be relayed to multiple units.

Key Features:
