Atlas Eos 4.0em Modular Distribution Block We live in an electrically noisy soup, permeated by all manner of potential interference. Standard mains distribution blocks and extensions often used for audio/AV systems can actually contribute to performance degradation, offering little in the way of shielding, and typically incorporating noisy neon power indicators, fuse holders and low-grade wiring/bus-bars which are all points of weakness. These factors and the degree to which they can degrade audio performance have perhaps been underestimated previously, only recently coming to play a critical role in many manufacturers' product design strategies. At Atlas, such issues have been a core consideration for several years, culminating in the introduction of our latest Eos 'em' power .
