Pro-Ject Amp Box S Stereo

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. 

Features 

  • Bi-Phase PWM(Pulse Wave Modulation) circuit 
  • Discrete design for ultra-dynamic playback and highest resolution 
  • SMD for short signal paths 
  • 1x40W@4ohms/1x28W@8ohms 
  • Ultra high-efficiency: approximately 80% of power consumption goes to “power out” 
  • Gold-plated, over-sized binding posts 
  • Trigger-switching with Loop-out 
  • RCA-Loop-out, for Bi-Amping, etc 
  • Metal case shields the electronics from vibrational and electromagnetic interference 
  • Outboard power supply included
