Azur351R
AV Receiver
The heart of a stunning 5.1 surround sound system, and brilliant with stereo music too
The 351R amp delivers superb-quality surround sound, plus stunning audiophile stereo for brilliant music reproduction, at amazing value. Our designers have obsessed over the audio, creating surround sound that truly immerses you in big-screen action and music reproduction so good it will make the hairs on the back of your neck stand up.
We call it "Sound First" design: we prioritise audio quality, and cut cost and clutter, to deliver the best-sounding AV receiver you'll ever hear at this price. For example, most living room setups are 5.1 (five speakers plus a subwoofer bass speaker). So instead of giving you a 7.1 receiver with two channels you'll never use, our engineers have spent the development budget putting better quality components in the bits you will use. They've also taken technologies from our pricier Azur 551R and included them in the 351R, including premium toroidal transformers for stunning bass response and pure sound and an all-metal chassis to minimise distortion.
The 351R is a home entertainment hub, with enough inputs and outputs to hook up all your kit. There's enough capacity to connect not just Blu-ray disc players and satellite set-top boxes, but games console and media players like Apple TV too, all in high definition via HDMI. There are plenty of inputs for hi-fi separates too.
And the 351R packs plenty of power, putting out 50 watts per channel (at 8 ohms) for room-filling surround sound, and 80 watts per channel (at 6 ohms) for a superb audiophile stereo performance from even the most demanding speakers. And a clever automatic setup mode adjusts the speakers perfectly, whatever the size and shape of your room.
Clever, keenly priced and stunning both for home cinema and music, the 351R is hard to beat ...Read more
As great for music as it is for movies
The 351R is designed from the ground up to perform at its peak not just when driving 5.1 surround sound speakers, but also to deliver stunning, pin-sharp stereo music from your main front speakers. Such versatility is rare indeed.
Powerful amplification
5.1 outputs delivering 80W RMS power stereo (2 channel, 6 ohms) and 50W RMS power surround sound (5 channel, 8 ohms).
Quick set-up
Whatever the shape and size of your room, the 351R’s CAMCAS (Cambridge Audio Microphone Controlled Auto Set-up) makes getting started a doddle. It uses a supplied microphone to measure sound levels from each speaker and then automatically tweaks their volume levels and delays so you get perfectly adjusted surround sound.
Dual Cirrus Logic 32-bit DSPs
High-quality and up-to-the-minute digital signal processors mean the 351R works with all the latest audio codecs and formats, including 3D video. And it will handle future formats for years to come.
Surround sound modes
Dolby TrueHD, Dolby Digital Plus, Dolby Pro Logic II, DTS-HD and DTS Neo:6 96/24. The 351R supports high-quality audio on all channels and allows a TV programme/film which is in 2 channel to be enjoyed in full surround sound.
“Sound First” design principles
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, best-value system you’ll ever hear. That means we remove stuff that you don't need and 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.
High-quality components
our London-based engineers carefully select technologies and the finest components to work beautifully together including toroidal transformers and X-Tract near-silent cooling, with a full metal chassis to optimise performance.
Toroidal transformer
At Cambridge Audio, we’re huge fans of what these premium components can do for audio quality. So, while other people reserve them for their top-of-the-line separates, we put them everywhere we can. The extra power reserves a toroidal transformer delivers mean not only a far better bass response, but also a deeper, richer sound across the board. For pure audio quality and minimum distortion, we accept nothing less.
All-metal case
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 introduce less resonance to any signal.
X-Tract cooling
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). It makes for a slim box too, the 351R is just 110mm high.
