The 651R features a range of quality components that fit with Cambridge Audio's principle of designing for 'Sound First.' This includes toroidal transformers for a high purity, low-distortion signal, discrete amplifiers to reduce noise, and X-Tract near-silent cooling combined with a rigid low-resonance chassis to maximize audio signal quality.

There's plenty of room-filling power, too. The 651R delivers 175-watts RMS per channel in stereo (two channels at 6 ohms) and 100-watts RMS per channel for home theater surround sound (seven channels at 8 ohms). And the environmentally friendly standby mode uses less than one watt.

For truly stunning home theater, the 651R features top-end 7.1 outputs (with the option to run twin subwoofers), dual Texas Instruments 32-bit DSPs to support the broadest range of surround formats and speaker layouts, and a comprehensive range of HDMI inputs and outputs.

Another feature of the 651R that's rarely found elsewhere is DTS remapping. This lets you easily rephrase DTS-HD High Resolution and Master Audio format audio signals to your 7.1 speaker layout perfectly.

DTS-HD High Resolution and DTS-HD Master Audio surround sound formats do not support more than one standardized 7.1 home speaker layout. So, if your home speakers are arranged differently to the layout the soundtrack was recorded in, they can end up out of phase. But simply choose the 7.1 speaker arrangement that matches yours on the Azur 651R, and the signal will be perfectly rephased.
