azur 751R V2
AV ReceiVeR
Matching Surround Modes
to suit your speaker setup
Personal preferences and room restrictions means every 5.1 or 7.1
speaker configuration will be slightly different, so it is possible the
original mastertrack of a 7.1 soundtrack was mastered with a different
speaker layout than the one being used in a customer’s home.
There are seven different layouts used by DTS (Digital Theater
Surround) for DTS HD and DTS HD Master soundtracks. To ensure
users enjoy the sound as the original sound engineers intended
(without moving the speakers every time) the 751R V2 will electronically
reposition each speaker to create the same experience as the
recording studio or cinema.
Toroidal vs EI transformers
We strive for audio perfection which is why the 751R V2 features
a powerful toroidal transformer. Cambridge Audio was one of
the first manufacturers to use toroidal transformers in the 1970s,
and we continue to use them today. Some of the benefits of a
toroidal transformer, over the cheaper, inferior EI transformers
used by most other manufacturers are:
High quality power output to the amplification circuits, with
no clipping of the waveform signal, to provide a consistent
signal
No transformer noise, buzz or hum
Sensational bass performance
High power output, to allow large and demanding
speakers to be driven at high volumes
Large power reserves, to allow the transformer to deliver
high peaks of volume when required
Fully shielded against internal and external electrical
interference, to maintain quality of power and signal
A typical cheaper El
transformer:
Weak inconsistent signal
No shielding
Noisy
Won’t drive powerful and
demanding speakers

Designer’s note
The 751R V2 has a HDMI Preview feature. This allows you to
display a thumbnail picture of all connected HDMI sources, and
quickly and easily select the desired input.

Class-leading connectivity
As well as comprehensive upscaling and upsampling capabilities,
the 751R V2 has a the full range of top-end home cinema receiver
features: 7.1 analogue inputs and outputs (with option to run twin
subwoofers), and a comprehensive range of HDMI inputs and outputs.
The 751R V2 has 6 HDMI inputs and 2 outputs, all of which are 4K and
3D compatible and with support for an audio return channel (ARC). The
751R V2 even has an asynchronous USB Audio input, acting as a high
quality external soundcard, allowing you to send up to 24-bit/192kHz
studio master quality files to the 751R V2 from your computer.
All metal design
Electronics (and therefore sound quality) are particularly susceptible
to vibration; that’s why we’ve used a low resonance, acoustically-
dampened metal chassis to eliminate as much vibration as possible,
ensuring that the most sound quality is extracted from each source.

Multi-room connections
Continuing the versatile specification, the 751R V2 also allows you to
run an independent zone 2. This means you can run audio and video
into a second room, and then watch or listen to different sources in
both rooms. Our zone 2 also features our unique “Follow Main” option.
“Follow Main” lets you listen to the same digital source that is playing
in the main room, in the second room (most modern amps will only let
you hear analogue sources in the second room).
Simple set-up
You can easily set the 751R V2 up by yourself using the Audyssey
2EQ auto speaker setup. For quick and simple installation in any
room this system uses the supplied microphone to perform multiple
measurements of the listening environment and automatically sets the
receiver up for optimum use dependent on your room’s acoustics.
Twin video outputs
The 751R V2 features two HDMI outputs. These can be used to run
two displays at the same time; ideal if you have a screen in a second
room, or want to use a projector for movies, but a TV screen for day
to day use.
Support for the latest formats
With the very latest technologies – including the Texas Instruments
dual 32-bit DSP for compatibility with all the latest CODECs and
formats, including 4K and 3D video, the 751R V2 will handle future
formats for years to come.
