Description stereo amplifier, Pro-Ject Stereo Box DS

Looking at this compact device, it is difficult to assume that the Pro-Ject Stereo Box DS is a complete stereo integrated amplifier. However, this device is equipped with four line inputs and one Mini USB B to connect to a personal computer. Digital-to-analog Converter in the amplifier is made based on the chip PCM 2706.

Unlike the basic model, the Pro-Ject Stereo Box DS is a dual mono configuration, which allowed to improve the quality of stereomerini. The amplifier stages in this unit is based on modules with pulse-width modulation of the audio signal (PWM), thereby achieving high efficiency. Each channel of the amplifier has two such modules, so the output current Pro-Ject Stereo Box DS increased significantly. This allows you to connect to it columns with a complex characteristic impedance, including a 2-Ohm. Also compared to the base version of the model in the diagram Stereo Box DS are perfect accessories audiophile.

Front panel made of thick aluminum sheet (it can be black or silver color), there is a large LCD display, which displays the basic modes of machine operation - set volume level and selected input. Also to control the amplifier you can use the supplied miniature remote control. Case Stereo Box DS is made of metal that provides a good protection of electronic circuits from external influences.

All contact surfaces of connectors gold plated amplifier to connect the speaker system provides a reliable screw terminals. Stereo Box DS is powered from an external source of 24 Volts and provides load current up to 5 Amps. The device has very low power consumption in Standby mode less than 1 Watt.

Due to the small size of this unit is very well suited for a compact Cabinet stereos when used in conjunction with broadband acoustics shelf of high class.
