Rotel RA-11 black

The RA-11 incorporates most of the functions and features of the RA-12. However, it is slightly less powerful (40 W per channel) and its chassis is a bit slimmer. Just like the RA-12, each critical component placed in the signal path has been meticulously chosen to ensure that the musical message delivered by the RA-11 will offer the maximum possible detail, dynamics, clarity and sensitivity.

The RA-11 is equipped with the same high-end Wolfson WM8740 24-bit/192 kHz DAC circuit, and like the RA-12, it has five analog inputs, four S/PDIF digital inputs, and an Apple-compatible USB input. Finally, the RA-11 can be controlled by the buttons on its front panel, by its infrared remote control, or via the RT-12 and the Rotel Remote app for iPhone and iPad.
