Integrated Amps : Cambridge Audio Azur 840A Class XD Integrated Amplifier Cambridge Audio breaks new ground with an entirely new class of amplifier in the shape of the 840A which marks the zenith of Cambridge Audio’s critically acclaimed Azur line-up. Embracing Cambridge Audio’s patent pending proprietary Class XD™ technology, the 840A brings together the quality of Class A amplification, the power economy of Class B designs, and most amazingly of all, avoids many of the distortion pitfalls inherent in Class AB designs. Completely separate pre-amp and power amp toroidal transformers and circuits make the 840A effectively a pre and power amplifier combination in one chassis Another enormous benefit is its ability to integrate seamlessly with a home cinema system. Fixed level inputs allow the 840A to provide the front channel amplification to systems which use an AV receiver. The receiver continues to provide centre and rear amplification. In addition to this innovative technology, the 840A uses an extremely sophisticated resistor ladder and relay attenuator for volume control and the same high quality relay switches for input selection. This enables high isolation between inputs, very accurate channel balance and leaves the amplifier completely free from the distortion associated with conventional semiconductor switching and volume control. As with all Azur products, the foundation of the Azur 840A's is a bespoke chassis. This comprises an incredibly thick 7mm front panel and extruded side panels, both fashioned from aluminium, which combine 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. Great attention has been paid to ensuring that all functions can be operated from the stunning aluminium-faced Azur Navigator remote. As well as offering full control over all the 840A's features and functions, this neat handset also enables track skip plus play and pause of iPods™ connected to Apple's iPod Universal Dock Azur 840A features Patent pending proprietary Class XD technology Oversized low flux toroidal transformers 120 watts per channel (8 ohms) 200 watts per channel (4 ohms) Completely separate pre-amp and power amp toroidal transformers and circuits make the 840A effectively a pre and power amplifier combination in one chassis 8 audio inputs - including 1 with balanced connections Sophisticated resistor ladder and relay based attenuator for volume/balance control Two pairs of very high current output transistors per channel Twin rectifiers and separate transformer taps for dual mono operation of the left and right power amplifiers RS232 port, IR emitter In and Control Bus In/Out for seamless integration with custom install systems A-BUS™ / Incognito™ Ready connections compatible with Cambridge Audio’s new Incognito multi-room keypads or other A-BUS compatible keypads allow the 840A to form the hub of a simple but highly effective 3 zone multi-room system Fixed level inputs allow the 840A to provide the front channel amplification when integrated with home cinema systems that use an AV processor Cambridge Audio proprietary CAP5 protection system Nameable inputs, backlit LCD screen 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 CD players plus the Apple Universal Dock Available in silver or black This item is only available to our South Florida customers at our West Palm Beach showroom.
