Product Description

The Project Amp Box Mono is a compact yet powerful mono power amplifier, designed to be paired with the Pro-Ject Pre Box in a complete Box system, the smallest separates available. The Amp Box mono is designed on the latest Class D technology, allowing it to deliver a powerful 28W per channel from a tiny box. We also sell the Amp Box Stereo, but using 2 Amp Box Monos instead produces a more power (28W rather than 20W) with better stereo separation.

- Trigger in and out
- Metal case shielded (prevents interference)
- Gold plated phono sockets
- Power supply included
- Dimensions (mm): 103W x 38H x 141D
