Cambridge Audio Azur 840C Up-Sampling Silver CD Player, Model CAMB840CSIL
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.
Features:
- Adaptive Time Filtering (ATF) asynchronous up-sampling technology converting
16-bit 44.1 kHz CD data to 24-bit 384kHz
- 32-bit Analog Devices Black Fin DSP
- Dual differential DAC configuration using high-end Analog Devices AD1955
DACs
- Fully differential anti-aliasing topolopgy based on linear phase Bessel
filters
- DC servo circuitry with no capacitors in the signal path
- Two digital inputs allowing up-sampling and playback of other sources
- Digital outputs allow recording of up-sampled audio
- Control Bus In/Out, IR emitter in and RS232 for easy multi-room compatibility
- Extruded aluminium side panels and solid aluminium front panel plus an ultra
rigid, acoustically dampened chassis
- Navigator style Azur remote control which also controls Azur amplifiers
