Pro-Ject Amp Box S3

Pro-Ject Amp Box S3

Lots of power in a small space

The Pro-Ject Amp Box S3 is an ultra-compact yet powerful stereo power amplifier that, in combination with a preamplifier such as the Pro-Ject Pre Box S2 Analogue or the Pro-Ject Pre Box S2 Digital, offers a sonically amazing, yet more compact alternative to one represents integrated amplifier. The new PCB concept and the sophisticated topology achieve less distortion and a better signal-to-noise ratio compared to the Amp Box S2.

By separating the power-intensive final amplification from the delicate signal processing in the pre-amp and by using two separate power supplies, both devices can do their work much more confidently and undisturbed. In addition, the loop-through output also allows the operation of several power amplifiers, for example for bi- or even tri-amping.

Technology for good sound

• The solid, brushed aluminum housing, available in silver or black, protects against electromagnetic interference and vibrations (microphonics).
• Bi-phase PWM circuit (Pulse Width Modulation)
• Hard gold plated RCA jacks and speaker terminals
• External power supply (included)

Features

• Compact, space-saving design
• Pro-Ject digital amplifiers are highly efficient: 80% of the electricity consumed is converted into power
• Loop-through output for bi/tri-amping operation with additional Pro-Ject Amp Box S3 or other power amplifiers
• Switching voltage input (12V/DC) for remotely switching the device on and off.
• Switching voltage can be looped through to other devices (e.g. to another Amp Box S3) for remote switching on and off

Technical specifications

• Output power: 2x 23W/40W at 8 ohms / 4 ohms
• Dimensions W x H x D (D with sockets): 103 x 36 x 104 (118) mm
