Product Description
The 840W is a high-end power amplifier that has been designed by the same team behind the 840A and uses an evolution of Cambridge Audios hugely innovative Class XDTM technology for a highly detailed naturally musical performance. The second generation Class XD is now complemented by a new output stage carefully adjusted to integrate with this novel technology, revised balanced inputs for lower distortion and noise. An awesome 200W @ 8 Ohms gives excellent load driving ability or, a truly massive 500W bridged mono can be harnessed for even difficult high-end speakers. At the core of the 840Ws strength is a patent pending, Class XD (crossover displacement) technology (first seen in the 840A) and which has been subtly revised following continuing post-launch development and critical evaluation. This unique design gives pure Class A operation at low levels, moving smoothly into an enhanced version of Class B at higher levels. To facilitate this, the Azur 840W amplifier includes a massive, oversized low flux toroidal transformer, incorporating a silicone-steel screen. In our ongoing development of Class XD we have conducted exhaustive research into further improvements of our amplifier designs to squeeze everything out of this innovative technique. This in turn led to a new output stage topology being developed which has been incorporated into the 840W. Two pairs of very high current output transistors are used per channel (for the amplifier output) plus an extra high current transistor per channel for the XD circuit. The 840W can also be used in either bi-amped or bridged mono configurations. When bi-amping, one 840W (of the pair) powers each speaker so that the tweeters and woofers each have their own dedicated amplifier channel. All this proprietary engineering is housed within our low resonance, acoustically dampened chassis which includes a 7mm thick aluminium front panel.
