Project Amp Box S

The Pro-Ject Box design Amp Box S is a phenomenally compact power amplifier, designed to perform at the same efficiency and audiophile standard as full-sized amplifier separates. The amp Box Design features an impressive 30Watt output, when combined with other Box Design units, this power amplifier will provide a flawless sound. 

Circuitry within the unit uses a highly efficient Bi-Phase PWM (Pule Wave Modulation) technology, with SMD parts to offer an astonishing audio performance while retaining a consistently cool temperature while in use. The sound quality that the Amp Box S is able to reproduce has been designed to offer as close a sound to Class A tube amplifiers as possible to offer a liquid and life-like sonic representation. 

The Amp Box S is smaller than most micro-systems and can be easily and discretely integrated within any environment. It can be remotely turned on or off using a trigger signal (included with the product is a 45cm power-on cable) so it can be conveniently operated. You can also bi, or tri-amp this unit, the remote signal can be relayed to multiple units.
