It’s the sound that matters:
Cambridge Audio has always had a
passion for sound quality, and this is
where the 751R stands head and
shoulders above the competition.
Utilising over 40 years of experience in
the production of award winning
amplifiers, Cambridge Audio truly believes
the new 751R to be its best sounding AV
receiver to date. Key to this claim are the
751R’s seven 120 Watt audiophile grade
fully discrete amplifiers which are kept
separate from the processing and input
stages and feature a substantial power
supply and an oversize low flux toroidal
transformer. This careful design of the
amplifier stages ensures that the 751R
can replicate the dynamics and scale
required for the most demanding movie
soundtracks whilst also being able to
reproduce a genuinely musical
performance with either stereo or multichannel
music sources. Every part of the
751R has been carefully designed to
offer the ultimate in audio performance.
From the ultra rigid, acoustically
dampened chassis, right down to the
critical selection of each individual
component, no stone has been left
unturned in the pursuit of audio heaven
from an AV receiver.
Power when you need it
Cambridge Audio has always used ‘real
world’ power ratings, which detail the
maximum power output when all
channels in an amplifier are driven.
Unlike some other companies, who may
use flattering figures into low impedances
or with only some channels driven to
exaggerate the claimed performance of
their amplifier stages, the 751R can
deliver a true 120 watts from all 7
channels, which will blow the competition
out of the water, and makes the 751R the
most powerful AV receiver in its class!
A great sound for any
environment
The 751R is also the first Cambridge
Audio receiver to feature Audyssey 2EQ
room equalisation, with a supplied
microphone for extremely quick and easy
installation. Also with Audyssey Perfect
Volume, the sound is fully tailored to fit
your listening environment perfectly, so
that you can hear music and movies just
as the artists and directors intended.
As part of Cambridge Audio’s ‘nocompromise’
approach to sound quality,
the 751R uses three (yes 3!) full DSP
stages: a Texas Instruments twin DSP
chipset provides multichannel decoding in
core one and then full post-processing
(including room EQ and volume
equalisation) in core two. Finally, a third
Analog Devices DSP up-samples all audio
signals to 24-bit/192kHz. For movies
and TV shows, the 751R supports all of
the latest surround CODECs, and can
fully decode all HD audio soundtracks
over both PCM and Bitstream. In
addition, the Analog Devices DSP running
Anagram Technologies Q5 suppresses
jitter whilst up-sampling all audio signals

AV Reciever
In its commitment to bringing high quality audio to the AV market, Cambridge
Audio is proud to introduce its new 751R AV receiver featuring full HDMI 1.4 3D
reception and processing.

to 24-bit/192 kHz, for the ultimate in low
jitter, high quality sound. For computer
audio, a USB input is capable of
accepting 24-bit/96kHz files from any
connected computer, to provide ‘better
than CD sound quality.
Cutting edge
As well as great sound, the 751R is full
of cutting edge video technology too:
The 751R boasts 6 HDMI inputs, and
2 outputs, which can send the same
output signal to multiple displays. All
incoming video signals can be scaled
to1080p by a high quality Anchor Bay
ABT2010 scaler, to ensure that all video
signals are output in the highest possible
quality, to complement the high quality
audio! And completing the perfect
picture, LipSync audio delay means the
user can simply adjust for processing
delays in the source or TV, to provide
trouble free viewing.
Big power from a small package
To extract such high levels of performance
from a compact unit is no mean feat.
Another crucial aspect of the 751R’s
audiophile pedigree is Cambridge Audio’s
– X-Tract, a proprietary forced convection
heat tunnel. This revolutionary design
allows the 751R to remain cool and silent
whilst operating at the highest possible
levels of power and performance.
