The Pro-Ject Amp Box S3 CI uses special pads optimized for professional use to connect speakers. There is also a standard 12V trigger input and output for any installation device and an RS232 interface. In addition, it should also be noted that the amplifier has not only an input sensitivity control, but also a low and high frequency control.
Amp Box DS2 Mono is a mono power amplifier from Pro-Ject Audio Systems. The four-layer printed circuit board allows for shorter signal paths, which improves sound compared to the previous model.
