Cambridge Audio has taken the Azur 840 series to its peak with the
introduction of two new models – the 840E pre-amplifier and 840W power
amplifier. The 840E is a high-end pre-amplifier which uses Cambridge Audio’s
new proprietary Terrapin™ modules for unprecedented audio fidelity forming
the perfect partner for the accompanying 840W power amplifier. A customisable
front panel display means tone controls can be selected and stored by
nameable input. Volume, input and tone are also all controlled by highly
sophisticated relay driven circuits.
Rather than use common op-amps for the critical low level gain stages of the
840E (and 840W) Cambridge Audio instead decided to design its own audiophile
amplifier modules. The subject of a separate research and development project
these unique modules have been designed with single minded dedication to the
very best audio performance possible. Two types exist, the TPA amplifier and
TPB buffer module fully optimised for their respective roles. Nicknamed the
Terrapins (because of their 10 pins) they add yet another dimension to
Cambridge Audio’s commitment to audio excellence.
A sophisticated resistor ladder and relay based attenuator for volume (1dB
steps) and balance controls allows remarkably accurate volume control with
channel balance. Each channel has its own relays and ladder for superb stereo
separation and imaging. This kind of feature is normally the preserve of
exotic high-end equipment and is relatively unheard of at this price point
As the pre-amp has its own power supply, it operates in complete isolation to
the power amplifier and does not suffer from any interference, something
which is also aided by two balanced inputs.
The 840E features an extremely attractive and user friendly front panel
display which is customisable to show which input is selected.
The Azur 840E makes room for eight inputs, two of which have both fully
balanced (XLR) and unbalanced connections, ideal for use with the Azur 840C
upsampling CD player. These inputs can be named as desired by the user on the
custom-designed display to show CD, MP3, Phono etc.
Completing the rear panel is an RS232 control port, and multi-room outputs to
connect the 840E to custom installations. This plethora of connections
enables complete integration with multi-room entertainment systems including
two way interface with touchscreen control panels. Alternatively, the 840E is
Incognito Ready™. This means that two additional rooms can access the source
components connected to the 840E via Cambridge Audio’s Incognito system
amplified keypads and passive speakers or active in-ceiling speakers. An
independent Incognito power supply links to the 840E, enabling audio and low
voltage power to be transmitted to each Incognito keypad using only one run
of CAT5 cable.
As with all Azur products, the foundation of the 840E’s excellence is a
bespoke chassis. This comprises an incredibly thick 7mm front panel and
extruded side panels, both fashioned from aluminium, which combine with a 2mm
formed steel base plate and specially designed vibration absorbing feet. The
result is an ultra rigid, low resonance, acoustically dampened platform for
the electronics to sit in.
The 840E is available in either silver or black and comes complete with the
latest elegant, slim-line navigator style Azur remote handset offering full
control of Azur CD players, Incognito keypads and discrete commands for
custom install use. As an additional facet, all Cambridge Audio remotes
feature iPod™ Command – which means that basic iPod controls such as
volume and track select can be controlled from the comfort of the user’s
sofa. This boon requires the use of an Apple or other universal dock.
