Azur 751R V2
The ultimate audiophile home cinema receiver - the Cambridge Audio Azur 751R will make your music sound as great as your movies, with both sounding out of this world. It's perfect for pumping out audiophile stereo and the biggest of big-screen surround sound action. And it'll squeeze the maximum detail from any audio and video source you throw at it.
Azur 751R Upsampling Home Cinema Receiver
The best for music and movies...
The 751R is designed from the ground up to perform at its peak not just when driving up to 7.1 surround sound speaker set-ups, but also to deliver stunning, pin-sharp stereo music from your main front speakers. Such versatility is rare indeed.
Using proprietary Anagram Technologies, Swiss-engineered algorithms developed originally for high-end audiophile applications, this boosts audio quality from any source to 24-bit/192kHz, while minimising errors. What's so special about ATF upsampling? By using clever algorithms to plot sample points to a curve, rather than a straight line, the ATF system gets closer to natural soundwaves - it's crazy science, but it works brilliantly, delivering lower jitter levels, fewer timing errors and a more naturally clear sound.
Each performing an independent function: surround format decoding; post-processing; and ATF upsampling.
7.1 outputs delivering 200W RMS power stereo (2 channel, 6 ohms) and 120W RMS power surround sound (7 channel, 8 ohms).
Plug in a laptop or other computer and this USB port bypasses its inferior-quality soundcard and instead upsamples the digital music to 24-bit/192kHz for better-than-CD-quality digital audio file playback.
Run as a 7.1 system, or as a 5.1 system with the option to bi-amp and bi-wire the hi-fi speakers or run a second zone in another room - the choice is yours.
Our latest-generation EQ, dynamic volume and phasing automatic setup system means the 751R 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.
This video processor upscales any source, including analogue 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", where your Blu-ray player, PS3 or video streamer has already upscaled content once, and your receiver then scales it again.
DTS-HD High Resolution and DTS-HD Master Audio surround sound formats do not support more than one standardised 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 751R and the signal will be perfectly rephased.
Most modern, surround sound home cinema receivers will 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 751R 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.
By focussing solely on the things that make music and movies sound and look so good that the hairs on the back of your neck stand up, and cutting out any extra cost and clutter, we aim to deliver the best-sounding system at this price you'll ever hear. That means we remove stuff that you don't need and which can introduce distortion to your all-important audio and video signals - like a phono stage, networking capabilities or a pre-amp in a home cinema receiver. Everything that's left is there to make your music and movies sound and look better.
As well as a full metal chassis, toroidal transformers and X-Tract near-silent cooling, the 751R features 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.
At Cambridge Audio, we're huge fans of what these premium components can do for audio quality. So, while other people save them for their top-of-the-line separates, we put them everywhere we can. As well as delivering a high purity, low-distortion signal they deliver a better bass response. For pure audio quality and minimum distortion, we accept nothing less.
Our near-silent cooling combination of funnelling heat through a heatsink and thermostatically-controlled fan means that our systems stay 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).
Chosen not just for its good looks (although we think our solid, brushed aluminium fronts make a great addition to any home), we design all-metal cases because they're very stable and therefore introduce less resonance effects to any signal.
