Cambridge Audio Azur 540R V3 User Manual
Page 2
Thank you for purchasing this Cambridge Audio Azur range AV Receiver.
We hope that you enjoy many years of pleasure from it.
The new 540R v3 is designed for excellent multi-channel surround-
sound performance without compromising on music reproduction.
As such the six fully discrete audiophile grade amplifiers are kept as
separate as possible from the processing and input stages. A large
power supply with low flux toroidal transformer and careful design of the
audio stages ensure that the 540R v3 can reproduce the dynamics and
scale required for modern movie soundtracks whilst also being able to
reproduce a genuinely musical performance with either stereo or multi-
channel music sources.
For the new v3 model we have made several enhancements. We have
added 2 in 1 out HDMI switching, tweaked the amplifier designs for
lower distortion, added a Stereo + Sub mode (digitally created sub) and
post-processing modes with PLII to allow creation of a 6.1 output from
2.0/5.1 DD or DTS material.
All video inputs are now fully freely assignable to any source, making the
unit very flexible despite its relatively small size and socket count.
A new Advanced Bass Management feature allows separate crossovers
and trims for PLII/Neo, DD/DTS and Stereo + Sub modes, plus a Bass
Augment function allows the front speakers to remain Large whilst also
sending front left and right bass to the subwoofer.
A full RS232 control protocol has been implemented and IR Emitter In
added making it easy to integrate the 540R v3 into a Custom Install
situation.
As usual all this proprietary engineering is housed within our
acoustically damped chassis with an Azur navigator remote control
supplied
Your 540R v3 can only be as good as the system it is connected to.
Please do not compromise on your partnering equipment. Naturally we
particularly recommend equipment from the Cambridge Audio Azur
range which includes CD and DVD players which have been designed to
the same exacting standards as this product. Your dealer can also
supply excellent quality Cambridge Audio interconnects to ensure your
system realises its full potential.
Thank you for taking the time to read this manual, we do recommend
you keep it for future reference.

Cambridge Audio Technical Director

The process of setting up the 540R v3 is first to make all the
connections to your speakers and source equipment and then set the
unit up via its On-Screen Display (OSD), as there are various settings and
adjustments that need to be made before the 540R v3 can be used.
However before you actually decide which connections to make or
perform any adjustments it is strongly advised that you read through the
‘540R v3 setup’ section of this manual first, starting on page 12.
A lot of explanation is included that will help you to choose the right
connection types for both your sources and TV.
