The Pro-Ject Amp Box RS2 power amplifier is built using a hybrid scheme - the preliminary amplification stage in each channel is implemented on a dual triode 6922 (6DJ8). The solid-state output stages operate in the traditional class A/B and provide up to 80 W in each channel when working on a load with a impedance of 8 Ohms and 130 W for a load of 4 Ohms. In bridge mode, the amplifier is capable of developing up to 350 W.
