Compact High-End All-in-One
Uniti Atom is a beautiful, compact multi-source music player that will seduce you with its amazing sound quality and outstanding feature-set. Its 40-watt integrated amplifier and high-resolution music streaming capabilities will fill your home with stunning high-fidelity sound. Uniti Atom is perfect as a high-end main system or even for use in the kitchen or study, where space is at a premium. Just add speakers. Our Naim App for iOS and Android combines all of your music sources in one place, making Uniti Atom even more appealing.

Under the Skin of Uniti Atom

We’ve gone to extraordinary lengths to maximise the sound quality from such a compact all-in-one player. From the substantial transformer, which ensures that the power supply is always smooth and stable, to the sophisticated, hand-wired analogue and digital circuitry, every element of the design in Uniti Atom has been considered for its effect on sound quality. 

Revolutionary New Streaming Platform
Everything about this new streaming board has been scrutinised to achieve the best possible sound quality. It’s extremely more powerful than its predecessor, has masses of memory, will adapt to new technology effortlessly and seamlessly integrates across Naim’s existing product range, including the Mu-so wireless music system.   

Uniti features an incredibly powerful 4th Generation 40-bit SHARC DSP processor. It’s so phenomenally accurate that it performs a staggering 2.7 billion 40 bit calculations per second, giving it enough power to resolve the most complex music signals with ease. The SHARC processor removes ‘jitter’ timing errors and performs mind-bogglingly accurate digital filter to feed premium Burr Brown DACs based on components from our reference streamer systems. The result is a smoother and more precise sonic performance.  

A/B Amplification

Uniti uses Class A/B amplification, with technology derived from our iconic NAIT integrated amplifiers. Filter sections in Uniti Nova are made using the finest quality through hole film capacitors and discrete transistors with Uniti Atom and Uniti Star using a combination of through hole and Surface Mount Design (SMD). The power amplifier sections are now twice as fast, feature substantial transformers and run from linear power supplies.

Digitally Controlled Analogue Volume Control

At the heart of all Uniti all-in-one players is an audiophile volume control, adjusting level in the analogue domain to a premium digital resolution. The design is taken from our NAC-N 272 streaming preamplifier and its smooth structure is inspired by our reference amplification system, Statement. We have also hidden the Bluetooth antenna underneath the central dial for a seamless aesthetic.

State of the art Wi-Fi
New Uniti all-in-one players feature the very latest Wi-Fi which is much faster than the original Uniti range. The superior Wi-Fi processor supports 2.4 and 5GHz, alongside much better internal buffer and memory – Uniti Nova will store up to one track’s (5 minutes) worth of buffer, which results in far fewer dropouts. The Wi-Fi aerials (one on either side of the product for optimum range) are integrated behind a slot machined in the heatsink. Behind the aerials we’ve also installed a back reflector to prevent any harmful radiation from entering the unit, which further increases range, and of course, improves sound quality. This incredibly detailed patent-pending innovation provides robust connectivity without the need for an external aerial. 

Revitalised Design
Conceived and built from the ground up by our engineers and designers in Salisbury, England, Uniti remains true to our core design principles. The new signature illuminated volume dial, inspired by our reference Statement amplification system, is just one of the features in this beautifully engineered brushed aluminium chassis, which also boasts extruded heatsinks for thermal stability and a highly-polished full colour LCD glass display providing you with rich imagery of your favourite album artwork. Impeccably crafted with materials chosen to be in complete service of sound, Uniti is alive with unique visual contrasts that make it a masterpiece of industrial design.

New and Improved Naim App

The new intuitive Naim App gives you effortless control over individual or multiple Uniti products. You can access all of your music, including your favourite radio stations, streaming services and playlists, explore artist discographies and biographies, and you can now update your system wirelessly with a single tap. The new app also now allows you to control both Naim streamers and hard disk servers, with no need for two separate apps.

Intelligent Remote Control
All aspects of Uniti’s design were considered holistically, including the design of a new bi-directional remote control. Very early on R&D realised that passive IR remote technology was not going to deliver the targeted intimacy. A ground up solution, both from a technological and a user point of view was sought and found with the bi-directional remote control. Beautiful white backlit buttons, a round volume display with segments that light up in harmony with the volume control on the player and easy pairing to any Uniti player, the remote is an intrinsic part of new Uniti.

Full Colour Display
With this range we wanted to deliver total connection to the user’s music collection. A very high grade full colour 5” LCD display provides rich imagery of album artwork and content. The screens have proximity sensors and thus will wake up as someone approaches the machine to display music meta-data, audio input information and more. There is also a selection of front panel buttons, including Favourites, stop and play.
