The amplifier has always been the heart of a hi-fi system, but for the new audio landscape, amplifiers need ‘brains’. The brain of the RA-12 is the Wolfson WM8740 24 bit/192kHz DAC, most often found in high-end audio products, and it ensures that the RA-12 extracts the full potential from its digital and Apple® authorised USB inputs. Traditional audio is not forgotten however so the RA-12 also provides four analogue line-level inputs and a phono input. The RA-12 can be controlled from its front panel buttons, via a remote handset, or via an RT-12 and the Rotel Remote app for iPhone and iPad. The RA-12 is however not just about versatility, it is a very high performance 60 Watts per channel amplifier that puts music at the top of its priorities.
