Pro-Ject Amp Box DS Mono Power Amplifier

£249.17 Exc. VAT |  


Project Amp Box Mono DS 

A ultra high-efficiency Bi-Phase PWM (Pulse Wave Modulation) circuit with SMD parts gives outstanding audio performance and stays cool on the outside.

The sound quality of Amp Box DS Mono is aimed to be as close as possible to Class A tube amplifiers with their liquid and lifelike presentation. This stylish amp is compact-sized and therefore lends itself to easy placement and can be switched on & off remotely via a trigger signal. A 45cm power-on cable is supplied for this purpose. 

For Bi- or Tri-amplification use, the remote power-on signal can be relayed to further units.


  • Improved PWM-Circuitry (Pulse Wave Modulation)
  • Improved signal spectrum and lower distortion 
  • Discrete design for ultra-dynamic playback and highest resolution 
  • SMD for short signal paths 
  • Class D amplification means low heat emission
  • Ultra high-efficiency: approx. 92% 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  
  • Outboard power supply included
