Small But Powerful Monoblock Amplifier
'Go monoblock' for less and take advantage of the sonic benefits of totally separate amps for each channel of a hi-fi or home theater system. Pro-ject's Amp Box S Mono is an ultra-compact single-channel amplifier that can be placed almost anywhere. It goes where larger amps just can't fit. Its small size and big audiophile performance make it ideal for bi-amp and tri-amp applications, too.
Despite the compact size, the Amp Box S Mono pumps out the power. It delivers a room-filling 40-watts RMS at 8 ohms and 60-watts RMS at 4 ohms – with a big 2 ohms drive capability.
"There's an impressive solidity and punch to the sound: far more than you'd ever suspect could come from compact boxes like these," reports England's What Hi-fi? magazine on the original Amp Box model. "The good news continues when you play something like 'Help' from The Beatles. There's a good sense of drive on this track, and everything is nicely separated and defined."
Tube-like Sound Quality
Thirty-five years of R&D by Pro-Ject went into the design of the Amp Box S Mono. An ultra high-efficiency Bi-Phase PWM (Pulse Wave Modulation) circuit with SMD parts gives outstanding audio performance. It fulfills the demand for high resolution, 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 Mono can be remotely switched on and off via a trigger signal, and a 17-inch-long power-on cable is supplied for this purpose. For bi-amp or tri-amp systems use, the remote power-on signal can be relayed to additional units.
The metal case helps shield the electronics from vibration and electromagnetic interference – and it stays cool on the outside. The outboard power supply keeps the chassis size small.
