Cambridge Audio Azur 851D volume control
Like new condition, original packaging and accessories.
Azur 851D Flagship Digital to Analogue Converter Digital music now comes from a multitude of sources, but the digital to analogue converters in most PCs, MACs, Laptops or TVs are often an afterthought. Bypass the same audio through the 851D’s twin premium DACs in dual differential mode and its 2nd generation Adaptive Time Filtering process and it’ll bring every drop of detail and depth back into your music so it can be heard exactly as it should sound.
We built the 851D using all of our hi-fi experience and the highest grade of components throughout to ensure it delivers the best sound in its class. You can connect up virtually any source and then let the 851D bring it to life. All data is put through our 2nd generation Adaptive Time Filtering that upsamples everything to 24bit/384kHz hi-res quality, no matter the original source. As a result, jitter is almost completely absent, and your music sounds amazing. Read more on our proprietary ATF upsampling technology here.
The upsampled music then passes through Twin Analog Devices DACs (very high-end digital to analogue converters) which are implemented in a dual differential configuration meaning each channel has its own DAC to process data. The result is lifelike stereo imaging where instruments can be heard in specific parts of your room with uncanny accuracy.
All of these audiophile internals are powered by a large toroidal transformer for the best delivery of a high quality and consistent signal, low noise and buzz levels, and huge power reserves.
We’ve built the 851D to connect with as many digital sources as possible. There are digital TOSLINK, S/PDIF, BNC and AES/EBU inputs, while if you add a BT100 Bluetooth dongle you can pair with compatible devices for wireless Bluetooth streaming. For your PC there’s an asynchronous USB audio input with a dedicated driver, allowing you to bypass the PC’s poor audio path. All inputs are upsampled to 24-bit/384kHz meaning you can connect up a world of digital source components including TVs, media streamers, smartphone docks and computers, and enjoy it all in amazing hi-res quality.
With premium XLR and RCA outputs you can then connect the 851D to the perfectly compatible 851A integrated amplifier with other sources. The 851D also has a digital volume stage built in so it can be used as a pure pre-amplifier – just connect it straight into our 851W power amplifier or a pair of active speakers for further sonic benefits.
