产品描述 

The RA-11 carries a similar set of features to the RA-12 but is slightly less powerful at 40 Watts per channel and is constructed in a slimline enclosure. Just like the RA-12, every critical signal chain component is selected to ensure that music from the RA-11 is delivered with as much detail, dynamics, clarity and emotion as possible. The RA-11 incorporates the same high-end Wolfson WM8740 24-bit/192kHz DAC chip as the RA-12 and the same complement of five conventional analogue inputs, four S/PDIF digital inputs, and an Apple authorised USB input. The RA-11 can be controlled through either its front panel buttons, via a remote handset, or paired with an RT-12 and the Rotel Remote app for iPhone and iPad.
