Eos Modular 2.5em
Flexible High Performance Power Block.

We live in an electrically noisy soup, permeated by all manner of potential interference. The ‘household’ 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 – all points of weakness.
At Atlas, such issues have been a core consideration for several years, culminating in the introduction of our latest Eos ‘em’ power cables and distribution blocks. The Eos Modular 2.5em is a robust, no-nonsense screened power extension block designed and built to deliver unimpeded power to audio system components.
The Eos Modular 2.5em block is housed in an elegant aluminium chassis, internally wired with the same 2.5mm² OFC conductors used in our Eos 2.5em power cable. As always, this consistency of elements is highly desirable, minimising material ‘barriers’ which are themselves potential points of weakness.
Each individual socket is optimised for low contact resistance ensuring unimpeded power transmission between sockets. An integrated direct ground drain path* for cables in our Grun Coherent Earth system reduces the system noise floor still further, typically removing the digital ‘glare’ which is a typical symptom of RFI/EMI noise degrading the audio signal.
‘Outrigger’ legs with rubber studs or conical spikes provide mechanical isolation or coupling, or optionally allow wall mounting.
The Eos Modular 2.5em block performs superbly as part of a complete Eos Power Management System, in which the most important cable is the one between mains socket and distribution block. Use an Eos 2.5em for the block and Eos 1.5em cables for other components.

* NB. The captive ground binding post should only be used to terminate Atlas Grun cables (please note this is not a safety earth and must never be used as such).

The Eos Power Management System
Designed to let you hear what your equipment’s really capable of. Eos power cables and Eos Modular distribution blocks are available in UK 13A, Schuko & Nema variants. Some Eos products also offer the option of Australian/New Zealand types.
Your local Atlas dealer/distributor will supply Eos products with the appropriate plugs for your market.
Reviews. What the specialist media say…

I am also aware of a deeper blackness at the end of the track when the music reaches its conclusion. The Eos 2.5 is a great mains block for any high-end audio system.

The Eos 2.5em is clearly excellent value for such a high-quality filtering mains distribution block.

…the Eos Modular 2.5em is an oasis of calm at the centre of your system. What we have here are two very impressive mains products from Atlas that both offer dedicated neutrality which, I have to say, is a novelty for much of the HiFi products I tend to hear nowadays.

Of course there are higher specification Atlas options available for use with more esoteric electronics, but the ones under review deliver first rate performance at a price which makes them seem like a genuine audio bargain.
