Cambridge Audio Unveils 7.1 AV Receiver

The Azur 650R claims to decode all the latest surround sound formats and is coupled with 7 x 100 Watt discrete amplifier stages. Using a completely new Cirrus Logic / Crystal chipset with the latest twin-core 32-bit DSPs, Cambridge Audio has enabled full support for Dolby Digital Plus, DTS-HD High Resolution and the new Lossless Dolby True HD and DTS-HD Master Audio formats.

DTS speaker re-mapping allows the playback of DTS-HD High Resolution or Master Audio formats with encoded height information on standard 5.1, 6.1 or 7.1 speaker setups.

A new video PCB with digital-domain video transcode means the 650R can also transcode analogue video inputs to HDMI for simplicity and flexibility, requiring just one cable to the TV screen. 

The 650R is also the first to feature Cambridge Audio Mic Controlled Auto Set-up (CAMCAS) with a supplied microphone for extremely quick and easy installation. And completing the perfect picture, LipSync audio delay means the user can simply adjust for processing delays in the source or TV.   

In addition the 650R’s seven 100 Watt audiophile grade fully discrete amplifiers are kept separate from the processing and input stages and feature a substantial power supply and an oversize low flux toroidal transformer.

“This careful design of the amplifier stages ensures that the 650R can replicate the dynamics and scale required for the most demanding movie soundtracks whilst also being able to reproduce a genuinely musical performance with either stereo or multi-channel music sources,” says the company.

The Cambridge Audio 650R has a suggested retail price of $2200.
