The Cambridge Audio 640R 7.1 multi-channel home cinema receiver is a remarkable piece of equipment which uses the company’s legendary build quality and then embraces the latest HDMI technology to produce a truly great home cinema receiver. The 640R produces an all round multi-channel surround sound performance whilst maintaining Cambridge Audio’s renowned musical reproduction.

The key to this musical performance is the seven 100W audiophile grade fully discrete amplifiers which are kept as separate as possible from the processing and input stages. This considered amplifier design ensures that the 640R can reproduce the dynamics and scale required for modern film soundtracks whilst also being able to produce a genuinely musical performance with either stereo or multi-channel music sources.

Cambridge Audio is always at the vanguard of embracing innovation and the 640R allows HDMI DVD players and set-top boxes to be routed to a TV or monitor. This enables direct digital transfer of high definition video to the screen for the very best picture quality. Indeed, digital connections are more important than ever and the 640R has inputs for up to three sources such as SkyHD™ box, Sony PSP™ and DVD player. These then need only one output to the screen.
