The Phono Box RS2 is fully balanced from input to output. The electronics are fully discrete, no operational amplifiers are used. In addition, the Phono Box RS2 has unusually advanced controls and a very complete set of features, considering its price range. High-quality workmanship and clean circuit board design are supposed to ensure good sound. The Phono Box RS2 uses split passive equalization for its RIAA and DECA curves.
According to the manufacturer, no other phono preamplifier is supposed to offer better or equally good options for gain adjustment as the Phono Box RS2. Very wide ranges from 40 dB (voltage gain of x100) to 70 dB (voltage gain of x3690) are possible. Thus, you can combine this phono preamplifier with a wide range of pickups and easily integrate it into a hi-fi system, precisely matching the volume to other sources, such as CD players or streaming devices. Load impedance can be continuously adjusted via a potentiometer and even seamlessly fine-tuned during playback.
To compensate for small imbalances between the left and right channels of a pickup, Pro-Ject implements another potentiometer to adjust the center of the sound stage in ranges of 2 dB to the left or right. This function can also be deactivated to keep the signal path as short as possible.
The Phono Box RS2 is powered by an external switching power supply with a nominal voltage of 20V / 3A and a guaranteed standby current consumption of 0.1 W, aiming to keep disturbing electromagnetic fields away from the amplifier section as much as possible,
The Pro-Ject Phono Box RS2 costs around 1,500 Euros in Germany.
