Atlas RCA Input Terminator AIT x 4
Atlas terminators are simple passive products that, by reducing the pathways to noise ingression or transmission, help reduce the noise burden in any system. This often leads to lower background noise and improved fidelity. Utilising the multi-award winning Integra RCA plug with its self-cleaning and non-compression contacts ensures no compromise in the critical contact areas.
Unused analogue input sockets in pre/integrated amplifiers can often act as conduits for pollutants such as RFI (radio frequency interference). A simple but effective way to minimise the problem is by the use of Atlas Analogue Input Terminators (AIT) on all unused analogue inputs.
Plug the AIT into the spare unused input RCA phono sockets on your integrated or pre-amplifier, being careful to avoid the outputs. With the AIT in place, your amplifier's unused inputs will be in a defined low noise state and resistant to the interference which can reduce sound quality.
Caution: Do not plug an AIT or DOT into the RCA analogue outputs on your amplifier – you may damage your equipment!
About Atlas Cables 
Atlas Cables are a major producer of interconnects and cables in the United Kingdom of Great Britain. All products are researched, developed and most are assembled in the Atlas purpose built factory in Scotland.
Many of these products are unique and use advanced techniques of production or manufacture in order to bring to the user the very finest quality products. With each new model we continue to push the boundaries of reliability and performance. It's little wonder then, that Atlas Cables have had so many mile-stone advances in the past and that Atlas Cables have secured so many awards in comparative tests against other products.
About Atlas Cables
Scottish cable maker that designs and builds its own conductors, connectors and cables rather than assembling bought-in parts.
Atlas researches, designs and produces its cables in Scotland, with a handful of exceptions. Many cable brands assemble off-the-shelf components, but Atlas specifies the conductors, insulation and terminations itself and tests the result in its own listening room. It offers a five-year guarantee on its cables.

The plugs are Atlas designs too
Atlas designs its own RCA plugs. The Achromatic and Ultra RCAs are built for low mass and high bandwidth, and the newer Metik connectors were developed for personal audio. Designing the connectors in house means Atlas is not limited to what an outside supplier already sells.
Three performance levels, with named ranges in each
The catalogue is arranged in three performance levels. Upgrade covers Element and Equator, Aspire covers Hyper and Ailsa, and High End covers Mavros, Arran, Eos and Zeno. You can choose the level that suits the rest of your system, then move up later without changing brand.
Custom options and a repair service
Atlas lists luxe and speaker termination options, so you can specify a cable to suit the equipment at each end. It also repairs, customises and upgrades its cables through a dedicated service, which means you can bring an older cable up to date instead of replacing it.
Why we stock Atlas
Atlas run pure copper conductors through most of the range rather than silver or silver plating. That gives a warmer, more forgiving balance than the silver-plated cables we sell. If your system is already leaning bright, Atlas is usually where we point you first. Hand-built in Scotland, and we have sold them since 2008.

I can report that Atlas AITs definitely work. The effect is subtle but very nice. The music sounded clearer and more natural. It was more open and transparent. Less restricted, less foggy. The background becomes perceptibly ‘darker’ and more silent with each additional AIT.
The more amplifier RCA inputs you treat with AITs, the better the result. They didn’t overdo things, there were no downsides. I bought 3 packs, enough AITs to treat all my input RCAs. Every single AIT improved the sound quality in every respect.
PS: the Atlas Mavros Grun interconnect cable has a ‘Grun’ earthing wire that plugs into a spare RCA input in the amplifier. (RCA inputs are in pairs). I found that inserting an AIT into the RCA input NOT occupied by the Grun wire made the Atlas Mavros Interconnect sound even better. Perhaps Atlas could provide an AIT with their Grun audio cables? (for the spare RCA input).
I’m glad I tried the AITs, they’re a really cost-effective upgrade.
Ps. thanks to the previous reviewer Steve. I found your review really informative and helpful.
Thanks also to Adam Senior at FutureShop UK. Everything he said about Atlas cables proved to be 100% true. Highly recommended.
The sound floor is indeed blacker and the sound stage is more solid and ‘stable’ – ‘stable’ is the word I’d use – there really is a more confident presentation of the sound stage
After speaking with the Atlas guy himself, he pointed out that better RCA interconnect cables would be a better investment at the price but since eventually I fully intend investing in a serious RCA interconect cable upgrade (at least one or two upgrades in the end) I feel that getting the best out of my present set up was what would best benefit my listening hours in the future
At the price, with the 4 I had, the Atlas guy advised me to swap them onto the different inputs to see which inputs offered the best improvement. After doing this I found that depending upon the pairs of inputs I plugged into, the benefits were different. One set gave me a livlier, zingier treble with significant added treble detail, whereas the other inputs offered a more stable sound stage – a choice had to be made
thus I invested in another set of 4 Atlas ATI and lo and behold I got the treble detail and the more stable soundstage
It is true that better interconnects would offer better value for money but in the end you still have the fuzzy RF system generated signal interference and eventually I’ll buy very good CD player/amp RCA interconnects anyway and then I definitely don’t want RF signal interference from the amp inputs
so, I’d definitely recommend these as a system upgrade - if you already have good RCA interconnects or intend getting better ones in the future then this is a sound investment. I’m very happy
NOTE WELL – DO NOT PLUG THESE INTO YOUR SPEAKER CABLE OUTPUTS ON YOUR AMP – YOU COULD DAMAGE YOUR AMP – MAKE SURE IT’S THE PAIRS OF LITTLE RED AND WHITE INPUTS YOU PLUG INTO (check with Adam senior of the future shop sales team if you’re not sure)
