Priced per piece (so you would need two for stereo output), this mono-channel power amplifier pumps out an impressive 40 Watts (60 Watts at 8 ohms!); all from within a small but well-built form factor. 

The Pro-Ject Box Design Amp Box S Mono is an ultra-compact mono-channel power amplifier, which is both efficient and audiophile. Built upon the same principles as the stereo Amp Box S, the Mono design packs more of a punch than its sibling, and using two together to drive a speaker each offers an impressive sound performance.

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 Mono is aimed to be as close as possible to Class A tube amplifiers, with their liquid and life-like presentation.

The Amp Box S Mono 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.

Available with a Black or Silver faceplate.

Key Features:

  • Bi-Phase PWM(Pulse Wave Modulation) circuit 
  • Discrete design for ultra-dynamic playback and highest resolution 
  • SMD for short signal paths 
  • 1x 60W at 4Ω / 1x 40W at 8Ω 
  • 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
