R4 Integrated Music System

Musically engineered for 21st century living

Discontinued product

Please note that R4 is now no longer in production. You may wish to consider our R3S model.

It did everything I asked of it and a bit more. By the end of my review period I had fallen in love with it and so had my wife.


The treble, mid and bass frequencies are sumptuously separated, delivering an overall sound that you might expect from a ‘proper’ separates system.

R4 Multi-Format CD Player

Multi-Format CD Player

For music and audio enthusiasts, CD is still one of the best ways to experience quality music and R4 features a multi-format player that will make your CD collection sound better than ever. Besides standard CDs, R4 also plays CD-Rs encoded with WAV, MP3, AAC or WMA music files and also displays track and artist information when this data is available on the disc.

R4 Class A-B amplifier

Audiophile Electronics

The electronic design of R4 is far removed from the mainstream of compact systems available today where integrated modules are used for simplicity of design and cost. With best sound quality in mind we developed our own discrete technology Class A-B amplifier system and use select audio grade components in critical signal paths. This method is usually only found in high-fidelity audio separates.

Great Connectivity

Voice controlled devices from the likes of Amazon and Google are interesting technologies, but deciding which may be right for you and which will stand the test of time can be daunting. This is a key reason why all our products incorporate Bluetooth and auxiliary inputs, so devices such as these can easily be connected and enjoyed with our products class leading sound. Also when technology changes (which it is bound to) then it is easy for you to upgrade as required.

High Quality Radio Tuners
R4 features a quality DAB/FM tuner and with DAB+ also included, it can be used in countries such as Australia, Denmark, France, Germany and Norway where this updated system is now being used. DAB+ also ensures that R4 is future-ready for new emerging digital markets and also for the roll out of DAB+ in the UK which is happening now
Bluetooth Bliss
R4 features aptX technology which partners with Bluetooth so you can stream music directly from compatible devices to R4 with CD quality sound from a distance of up to 10 metres. Bluetooth’s ease of use has made it the foremost method for wireless audio streaming and it works with virtually all leading music Apps including Spotify, Apple Music and BBC iPlayer Radio. Most importantly sound quality over Bluetooth with R4 is outstanding.
Connect, Playback and Charge
R4 has great connectivity allowing auxiliary devices such as a turntable, Amazon Dot, Google Chromecast or Apple AirPort Express to be easily connected. Also featured is a multi-purpose USB socket which allows you to charge smartphones and also playback music stored on a memory stick or portable hard drive in a variety of popular audio codecs. In particular R4 makes a superb TV sound system, with its optical digital input providing a convenient connection point for most modern TVs.
Stylish and Intuitive Controls
In our opinion products covered with buttons look confusing and ugly, so our trademark RotoDial controller provides a truly stylish solution. Furthermore, with all of our models now mirroring this interface, whichever model you own, you will intuitively know how to use each without instruction. In addition, R4’s custom remote control allows all major functions to be operated without moving from the comfort of your chair.
Bedroom Bliss
Perhaps slightly too big for your average bedside table, but on a chest of drawers R4 will make any bedroom sound better. With the supplied remote control you can operate R4 from the comfort of your bed and with programmable dual alarms you’ll be able to wake or doze exactly as you want. Connect your bedroom TV to R4 and you’ll have a blissful audio/visual retreat.
Clearly Brilliant
With the latest technology Organic LED (OLED) display, programme and menu information are shown on R4 with vivid clarity. The display retains its high contrast at any viewing angle and the display brightness can be adjusted to suit your requirements, both in standby mode and when active.
Beautiful Sound Design
With 30+ years of experience designing high-fidelity audio systems we understand the importance of cabinet and drive unit design to create beautiful natural sound. Like every model in our range R4 is crafted from materials chosen for their exceptional acoustic properties and our drive units constructed for optimum dynamics and frequency response.
