Finally, a home-cinema receiver that makes your music sound as great as your movies without breaking the bank. The Cambridge Audio Azur 651R is perfect for pumping out audiophile stereo and the biggest of big-screen surround sound action. You'll need to search far and wide to find an amp as versatile as the 651R in its class. Unusually, 651R is equally at home delivering the passion and fidelity of inspiring stereo music as it is making you leap out of your seat to big-screen surround sound action.

Producing brilliant audio in both stereo and surround modes, Azur 651R features a range of quality sound-first components: Toroidal transformers for a high-purity, low-distortion signal; discrete amplifiers to reduce noise; X-Tract near-silent cooling combined and a rigid low-resonance chassis to maximize audio signal quality. And there's plenty of room-filling power too. Azur 651R touts 175WPC power in stereo (2 channels at 6 ohms) and 100WPC RMS power per channel for home-cinema surround sound (7 channels at 8 ohms).

The Azur 651R doesn't slouch in video performance, either. An Anchor Bay ABT2010 scaler coaxes 1080p Full HD detail out of even analog video signals. The amp also features a unique scaler bypass mode that improves picture quality by preventing "double-scaling" content that has already been upscaled externally (for instance, on a Blu-ray player or PS3). Top-end 7.1 outputs (with 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 are standard. 

In addition, this entertainment hub also features Cambridge Audio's unique "Follow Main" Zone 2 option, which lets you listen to the same digital source that's playing in the main room in another room. No matter how you view it, and no matter what your primary needs, Azur 651R has you covered. We cannot believe the reasonable price. You won't believe the outstanding performance.

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

Full Room Audyssey Room EQ
Our latest-generation EQ, dynamic volume and phasing automatic setup system means the 651R will always sound at its best, no matter what shape or size your room is, and no matter where you sit - with setup optimised for three separate seating locations.

Zone 2 with "Follow Main"
Most modern, surround sound home cinema receivers let you run a second audio zone somewhere else in the house. You can listen to one piece of music in one room, while listening to something else in a second room. The catch? The second room can only use an analogue source for the audio. Of course, the 651R can do this too. But with its "Follow Main" mode, it can do something more - something unique to our receivers. In "Follow Main" two rooms can simultaneously receive the same digital audio signals, including the audio from HDMI.

Anchor Bay ABT2010 Scaler
This video processor upscales any source, including analog standard definition, to pin-sharp 1080p Full HD. The amp also uniquely features a "bypass" mode to improve picture quality by avoiding the common problem of "double scaling" wherein a Blu-ray player, PS3, or video streamer has already upscaled content once, and your receiver then scales it again.

Audiophile-Grade Components
As well as a full metal chassis, toroidal transformers, and X-Tract near-silent cooling, Azur 651R has isolated input and video processing boards, individual crossovers for each speaker, and Advanced Bass Management to ensure minimum noise distortion, maximum video quality, and the best quality audio out of whatever sound format is playing.

X-Tract Cooling
A near-silent cooling combination of funneling heat through a heatsink and thermostatically controlled fan means that Azur 651R stays cool without delivering distracting noise. Only at moments of peak power use will the fan really be at full speed (and those moments, of course, will be when you won't be able to hear it).

Dual Texas Instruments 32-bit DSPs
High-quality and up-to-the-minute digital signal processors mean the 651R plays all the latest audio formats including: Dolby Digital, DTS, Dolby Pro Logic II/x/z, Dolby True HD, Dolby Digital Plus, DTS-HD Master Audio, DTS-HD High Resolution Audio and many more.
