Each cell will see the product enter as a series of components and leave as a fully closed and tested product ready for shipping.

Initial reaction from retailers and distributors has been extremely positive with current forecasts now more than double initial prediction. This has meant planning a staggered launch across the range to meet demand. The new build cells will initially focus on Uniti Atom and Uniti Core, ramping up output over Q4 2016. February will see the start of Uniti Star and Uniti Nova production. Planning way ensures that customers globally can receive first orders on product this year.

Historical Background

It’s arguable of course, as is everything in audio, but most would agree that the NaimUniti and the Naim UnitiServe were the key drivers in the growth of networked audio products. There had been niche networked products that had been successful before this, like the Naim HDX music server, but Uniti delivered performance, with the sales volume to gain the critical mass that changed the shape of the market.

Uniti of course was also very significant for Naim allowing a reach into customers and distribution channels who would never have considered Naim in the past as it was considered highly desirable but aspirational due to the brands higher-end products and limited distribution.

Technical Background – New Uniti

Streaming Board: Naim’s new exclusive streaming board is a co-design introducing Naim’s design philosophies into an existing design to shorten the development time for this eight-layer board and to ensure approvals of the various key features. Going it alone was considered but with licensing and approval times and complications increasing it was decided to partner and to include customer demanded features rather than develop from scratch and potentially miss key user features which can vary considerably market to market. As an example Naim’s research indicate more customers even of its NDS high-end streamer are choosing to use Tidal and Spotify.


Partnering allowed Naim to add its expertise in audio board layout and also to move the digital connectivity to I2S over LVDS. Deciphering the alphabet soup; it means that the digital signal is sent over I2S which has the benefit of a separate clock signal, in contrast to S/PDIF which doesn’t, resulting in lower jitter. Low Voltage Differential Signaling allows digitals comms with high accuracy but with a very low radiated field. Given the mixed analogue/digital nature of network players keeping radiated fields as low as possible is an essential.

State of the Art Wi-Fi

New Uniti all-in-one players have significantly superior Wi-Fi capability (802.11b/g/n/ac) compared to the original platform; it is five times faster and much more stable. The Wi-Fi processor supports 2.4 and 5 GHz speeds and will be the best in the market. Alongside this, all have a much larger internal buffer and memory – they will buffer around one track’s data, which results in far fewer dropouts compared to the old platform, that could only store up to a minute’s worth at CD data rates. The Uniti systems have a patented hidden and integrated Wi-Fi aerial behind a slot machined in the heatsink between the fins.

CD Ripping

New Uniti delivers bit-perfect CD ripping to create accessible files that can be served to any UPnP streaming system on the network. The system uses the designed in EAC (Exact Audio Copy) software to extract the files which can be stored as WAV or FLAC lossless files. The CD playback component on Uniti Star has been custom integrated and takes advantage of the faster-than-playback read rates, so more is buffered into RAM allowing excellent audio extraction (as accurate as possible to achieve great sound) from the CD


Internal Storage

Uniti’s internal databases allow easy transfer of your music library to your preferred storage devices. Uniti Star has a built in CD drive that allows immediate bit-perfect CD ripping and with Uniti Atom and Uniti Nova there is the option to plug in a USB CD-ROM drive and rip to an HDD in the other USB socket. The database has a limit of 20,000 tracks for Uniti Atom, Uniti Star and Uniti Nova. Uniti Core has a significantly larger database capacity and can rip to NAS and store 100,000 tracks assuming the HDD has the capacity. Naim will issue a list of suggested external drives soon.

A/B Class Amplification and Power Supplies

Uniti uses Class AB amplification, with technology derived from our iconic NAIT integrated amplifiers. A/B is costly to implement and has many technical parameters to overcome especially in highly packed cases (but still easier than digital amps), but in spite of these challenges we select class A/B for one reason only, musical performance.

Filter sections in Uniti Nova are made using the finest quality through hole film capacitors with Uniti Atom and Uniti Star using a combination of through hole and SMD. The power amplifier sections have been updated, feature substantial transformers and run from linear power supplies.


The power supply for the power amplifier sections was also further increased to the biggest size that would fit. All Uniti power supplies when running are linear. When in standby a relay switches over to a small SMPS to bring power consumption to within regulations. On power up this SMPS is completely out of circuit electronically and mechanically.


The new Atom, Star and Nova now feature an incredibly powerful new 4th Generation 40-bit SHARC DSP processor, the ADSP 21489 capable of 2700 MFLOPS running at 450Mhz. The SHARC processor implements Naim’s RAM buffer (first used in the DAC and NDS and called zero S/PDIF) then 16 times oversampling and digital filtering. The oversampling and digital filtering software in the DSP is Naim written. This allows the digital filter section in the Burr Brown DACS to be bypassed delivering significant sound quality improvements.


All three new Uniti player products use premium Burr Brown DACs and analogue filter sections and output stages constructed from similar high-end components to those in their respective preamplifier sections. Using an extremely powerful SHARC also allows for future updates both in performance, formats and features.

Volume Control

The heart of any good preamplifier is the volume control. All new Uniti systems feature a digitally controlled analogue volume control. It provides an interface directly with the buttery smooth and beautifully illuminated top surface volume control, first conceived for Statement. The illuminated volume segments are reflected in the same fashion on the remote control and will adjust accordingly on the top surface ring if the volume is changed remotely.

HDMI ARC (Audio Return Channel) - optional on Uniti Atom from Q1 2017

HDMI is the 21st Century’s SCART lead, it carries video, audio and control signals but where SCART was analogue, HDMI uses digital technology. HDMI ARC carries the digital audio signal.

Plug an HDMI cable from the TV’s HDMI ARC connector to the Uniti and whichever input on the TV is selected the TV sound will be sent digitally to the Uniti and Uniti will decode (PCM Stereo only) and play it. The HDMI cable will also send TV remote control volume commands: the TV remote will control the Uniti’s volume control making the process easy for the whole family to use. It can also control the inputs of Uniti, for example: turn on the TV and Uniti will turn on and select the HDMI ARC input automatically. Then turn the TV off and Uniti will turn off.

Galvanic Isolation

The HDMI inputs on Uniti Atom, Uniti Star and Uniti Nova are galvanically isolated to ensure that noise from the TV power supply or indeed any other devices connected to the TV do not affect the Uniti’s performance when playing any source.

Control App

New Uniti all-in-one players can be controlled via the supplied remote control, or via the Naim Control app for iPad, iPhone, iPod and Android. The Control app puts a world of music at your fingertips. If you have other Naim streaming products on the same network, you can select rooms and enable party mode directly from the app.

Wireless over-the-air updates

The new range improves dramatically over the original Uniti range concerning updates. The new Uniti all-in-one players feature wireless updates that are controlled via the Naim app. The app will notify the user when an update is available, the user can accept, at which point the update will commence seamlessly

RF 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. So, 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 knob on the player and easy pairing to any Uniti player, the remote is an intrinsic part of new Uniti.
