Box Design Amp Box S Stereo Power Amplifier overview

Pro-Ject Stereo Box S Color:Black Integrated Amplifier

Manufacturers Product Description

Ultra compact power amplifier - efficient & audiophile! A ultra high-efficiency Bi-Phase PWM (Pulse Wave Modulation) circuit with SMD parts incorporates 35 years of R&D and gives outstanding audio performance, while staying cool on the outside. It fulfills our demand for high resolution with superior micro dynamics and room-filling power. Sound quality is aimed to be as close as possible to Class A tube amplifiers with their liquid and lifelike presentation. The Amp Box S is micro-sized and therefore allows 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.
