The 840C marks the zenith of Cambridge Audio’s critically acclaimed Azur
line up. Like all Azur products, the 840C promises unseen levels of
performance and engineering excellence to the price points in question. But
rather than redefining expectations in the entry-level market, the arena most
often associated with Cambridge Audio, the company will reinvigorate the
mid-end price sector.
The 840C embraces a raft of proprietary technologies including ATF™ (Adaptive
Time Filtering) asynchronous up-sampling technology which has been
developed in conjunction with Anagram Technologies of Switzerland. This system
intelligently interpolates 16-bit/44.1kHz CD data to 24-bit/384kHz data,
through the use of a 32-bit Analog Devices Black Fin DSP (digital signal
processor). This in turn feeds two 24-bit/384kHz DACs from the same company
in dual differential formation.
Each DAC handles just one channel for excellent stereo imaging, operating
fully in differential mode for exceptionally low distortion and noise.
Both unbalanced RCA and balanced XLR outputs are fitted. Two digital inputs
are also provided which even allow the up-sampling and playback of other
sources such as a DVD player via the Azur 840C. In addition, a recording
digital output can even allow bit-for-bit data or upsampled data at 48, 96 or
192 kHz to be recorded by a suitable device.
A Control Bus In/Out, an IR emitter in connection and an RS232 port are
provided for easy multi-room connectivity. The RS232 protocol enables a
two-way interface with third party home automation touchscreens.
As with all Azur products, the foundation of the 840C’s excellence is a
bespoke chassis. This comprises an incredibly thick 7mm front panel and
extruded side panels, both fashioned from aluminium, which combines 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.
