The second generation Class XD is nowcomplemented by a new output stage carefully adjusted tointegrate with this novel technology, along with revisedbalanced input connections for lower distortion and noisecircuits. Each channel uses 2 pairs of very high outputtransistors to ensure that the 840W can drive even themost demanding load At the core of the 840W’s strengthis a patent pending, Class XD (crossover displacement)technology This unique design gives pure Class A operationat low levels, moving smoothly into an enhanced version ofClass B at higher levels.The 840W delivers an impressive 200 watts per channel instereo mode, and can be bridged to output a massive 500watt mono output. Also included is the latest development ofCambridge Audio’s proprietary CAP5 protection system.CAP5 (Cambridge Audio Protection 5) is an innovative andintelligent protection system. It constantly monitors theamplifier, without degrading signal purity, ensuring ultimatereliability and high performance from this mighty amplifier.Azur 840w FeaturesCambridge Audio, Gallery Court, Hankey Place, London SE1 4BB©2007 Cambridge Audio Ltd.
