High End Soundbar

Our nuPro XS-8500 RC is a real high-end soundbar that can convince with its sound all along the line. At 120 cm, it reproduces stereo significantly better than its narrower peers. The soundplate not only offers more volume, but also the possibility of providing a footprint for TV sets weighing up to 100 kg.

nuPro XS-8500 mit TV

Upgrade for your TV

As a classic upgrade for the TV, the nuPro XS-8500 RC provides more volume and clearer voices on the TV. When connected via HDMI ARC, you can also conveniently control the volume with the TV remote control.

nuPro XS-8500 Stereosoundbar

Replaces the stereo system

The nuPro XS-8500 RC was developed for the greatest possible detail reproduction and is therefore also suitable as a replacement for the classic stereo system. Your favourite tracks can arrive via an existing CD or network player through the digital inputs, or streamed from your smartphone with Bluetooth aptX HD.

nuPro XS-8500 mit Subwoofer

DSP master 

The high-performance DSP processing controls different amplifier trains for different chassis. We also use our highly developed DSPs: Movie, Music and the popular Voice+ for perfect voice intelligibility. Signals are processed at up to 384 kHz/32-bit - which also demonstrates the system's performance.

X-Connect und X-Connect Surround  

Thanks to Nubert's own wireless standards, it is easy to connect several nuPro XS speakers to the nuPro XS-8500 RC - for a powerful multi-channel system. It is also possible to connect an active nuSub bass speaker wirelessly - or in the traditional way via cable. Well, with a lower cut-off frequency of 30 Hz, this is by no means essential, but some users never get enough of deep bass. Further information.

X-Remote App

X-Remote

Of course, we include a handy premium remote control with all nuPro XS speakers. But with our X-Remote app, you also have another convenient option for remote control. Working with the energy-saving Bluetooth LE, you will find all setting options and functions clearly arranged in the app.

X-Room Calibration

Calibration - that always sounds like a lot of work and a lot of expertise. Not with our X-Room calibration, which conveniently corrects the bass range from 20 to 160 Hz by -/+ 6 dB using a fully parametric EQ via smartphone. You'll be enjoying pure, dynamic sound in no time at all. For Android devices, an additional microphone available from us is required due to different hardware equipment.

X-Room Calibration

Intended Use

This speaker is designed exclusively for sound reproduction in dry rooms. Use the speaker only as described in this manual. Any other use (particularly safety-relevant or medical use, installation in open environments like IP-certified products) is considered improper and may result in property damage or even personal injury. Nubert electronic GmbH does not assume any liability for damages caused by improper use.

General Information

Never operate the loudspeaker unattended!

Danger of Electric Shock!

To avoid the risk of electric shock, the speaker may not be opened by the user. There are no user-serviceable parts inside the speaker. Service work and repairs are reserved for qualified specialists authorized by Nubert. If you need service, please contact Nubert electronic GmbH directly (info@nubert.de)!

Danger of Suffocation!

Never let children use or play with the speaker, remote control, or packaging unattended. There is a risk that children will get caught in the packaging film and suffocate. Make sure that children cannot remove any small parts from the devices! These parts, like the remote control battery, could be swallowed and cause suffocation. In case of swallowing any parts, contact a doctor immediately!

Danger of Injury or Damage!

When moving the speaker, take care to avoid injury and damage!

Caution!

Since the speaker can only be completely disconnected from the mains at the mains input on the rear of the unit or by pulling the mains plug from the socket, it must be positioned so that you have free access to the mains input or mains plug. If any of the following situations occurs, the loudspeaker must be switched off immediately and disconnected from the mains. Contact Nubert electronic GmbH (info@nubert.de) immediately:

  • The speaker has been damaged or has fallen down.
  • Power cord or plug is damaged.
  • Objects or liquid have gotten into the loudspeaker.
  • The speaker has been exposed to excessive moisture or rain.
  • The speaker does not work properly or exhibits a significant reduction in performance.
  • The loudspeaker smells burnt, develops smoke, or makes unusual noises.

Enclosure

We recommend commercial window cleaner sprayed onto a cotton cloth. This allows almost all fingerprints and dust to be easily removed. Alternatively, you can also use window active foam.

We advise against the use of microfibre cloths! These can cause mini scratches in the surface.

Diaphragms and Speaker Chassis

To remove dust from a loudspeaker chassis, a lint-free cotton cloth is sufficient to wipe the membrane lightly with very little pressure.

Technical information


Subject to technical changes.

Soundbar of a new generation

The nuPro XS-8500 RC is Nubert's most powerful and high-performance soundbar to date. The nuPro platform has been further developed and improved in the areas of sound, features and technology. Whereas the previous approach was to replace the stereo system on the TV with a soundbar, the aim is now clearly to create a replacement for the bulky surround system, with even higher hi-fi standards in terms of sound and volume. With complementary active speaker models, even flexible and wireless 7.1.4 playback is possible.

Sustainable development

The nuPro XS-8500 RC is the result of years of in-house development with extensive fine-tuning for breathtaking sound and the highest possible performance. We have not only fulfilled our customers' wishes, but also created a soundbar that is future-proof for several years to come, and have therefore combined several evolutionary steps - in a true soundbar revolution.

Subwoofer integrated, speech optimised

If Dolby or DTS are present, the nuPro XS-8500 RC will automatically reproduce a suitable downmix signal. In concrete terms, this means that all channel information is added up and then applied to the corresponding drivers of the soundbar by our DSP. The nuPro XS-8500 RC offers a precise bass response of 32 Hz (-3dB), which is usually expected from high-quality subwoofers. The two 204 mm woofer drivers receive the bass signal from the LFE channel, for authentic explosions with high precision without the need for a separate subwoofer. Since we place particular emphasis on speech reproduction, we use four specially optimised midrange drivers in a symmetrical arrangement with a diameter of 119 mm. This allows for the most linear reproduction with the best speech intelligibility for current series streams and blockbusters in your own four walls. Our special 25 mm driver with high power handling and finest resolution takes care of the clear and detailed reproduction in the high frequency range. The harmonious interaction of the selected individual components and 820 watts of peak power ensure the ultimate performance in the living room in the smallest of spaces and the simplest of applications.

Ultimate TV base

At 120 cm wide, the high-end soundbar is an impressive sight, with a solidly braced cabinet for the best possible sound. The side effect is the enormous stability of the nuPro XS-8500 RC. TV sets weighing up to 100 kg can be placed on it. The elegant lacquer finish rounds off the elegant look. This is matched by the magnetic cover, which is only 10 mm thick and makes the soundbar look less technical. The acoustically transparent fabric allows the sound to remain undistorted and the OLED display to be read at the same time.

High-end sound performance

All Nubert loudspeakers focus on linear and transparent sound to reproduce music and film as the original signal dictates. Our claim is to achieve maximum bass from compact enclosures. The nupro XS-8500 RC stands in exactly this tradition and consistently applies the findings of our previous loudspeaker developments.

With our high-end soundbar, you can replace the entire stereo system as well as the surround system. For this purpose, we have not only integrated many connection options, but also optimised the details. The arrangement of the drivers is based on the D'Appolito arrangement of our centres, so that an even more homogeneous horizontal dispersion is achieved. This way, the stage image becomes wider. The tweeter moves upwards, reducing edge dispersion and bringing the midrange closer together. This improves stereo imaging and spaciousness for an even greater sound experience. All in all, the result is a true hi-fi reproduction for the soundbar format.

Connections

Our nuPro XS-8500 RC offers a variety of connections for a wide range of sources. Certainly the most important and most frequently used is the HDMI eARC connection, which enables the transmission of the sound signal from the TV including the 3D audio formats Dolby Atmos and DTS:X. Two optical (TOSLINK) or coaxial inputs are available for classic CD players or modern network players. A record player with integrated preamplifier can be connected to the analogue input.

The smartphone connects via Bluetooth aptX HD. For modern Smart TVs, the aptX Low Latency standard is also available with a lower time delay.

The nuPro XS-8500 RC can be easily expanded with additional active speakers thanks to X-Connect Surround wireless. Up to eight surround speakers can be integrated. Nubert subwoofers from the nuSub series can also be connected wirelessly or via the Sub Out output on the soundbar.

Surround on the next level

We have a lot of enthusiastic customers for our soundbars. We often get praise not only for the great stereo sound, but also the question of wireless rear speakers. We have not only fulfilled this wish in the nuPro XS-8500 RC, but exceeded it. With support for Dolby Atmos and DTS:X, the two major 3D audio formats are integrated. With our nuPro XS speakers, the soundbar enables up to eight wireless channels in the new X-Connect Surround wireless standard. This makes integrating rear speakers a breeze, and puts an end to running annoying passive cables across the room. Later in the year, our active ceiling speakers will be available, making it even easier to add a layer of sound. This means that nothing stands in the way of flexibly expanding the All-in-One system to a true 7.1.4 home cinema.

X-Connect Surround

With DTS and Dolby, High Res in decoding for the individual channels has been standard for years. The challenge during development was to realise this quality with secure and stable radio technology. The result is an update for our stereo standard X-Connect. It becomes surround-capable with 48kHz/24Bit resolution. We call this new version X-Connect Surround and mark all products in our range with the new logo.

Energy

This sound bar is equipped with a convenient automatic energy-saving feature that switches the speaker on independently or puts it into the energy-saving stand-by mode when not in use. In this stand-by mode, which can also be activated manually via the app, remote control or the control pad, the speaker consumes less than 0.5 watts. If desired, the nuPro XS-8500 RC can also be completely disconnected from the mains via a rocker switch. The wide-range power supply allows this active speaker to be used on mains voltages from 110/120 to 230/240 volts.

App and room measurement

As an alternative to the supplied remote control and the control pad on the unit, the free Nubert X-Remote app for iOS and Android can also be used. The use of the app is particularly recommended for complex operating procedures, as it presents advanced functions such as the equaliser or the setting of the cut-off frequency in a particularly clear way. The programme automatically adapts the menu interface to the equipment of the respective connected device. A speaker from the nuPro XS series offers different functions than the nuConnect ampX integrated amplifier, for example.

The app's advanced features include bass equalisation, which enables optimal low-frequency reproduction at the listening position and reliably minimises dreaded room modes. The application is very easy: Start the app, establish the connection with the device and navigate to the entry X-Room Calibration via the main menu in the upper left corner. Now follow the instructions of the app to start the calibration. To do this, simply play and record the test signal (white noise) for one minute; the process is largely automatic. The smartphone or tablet then calculates the best possible tuning curve from the played back test signal and then transmits it to the digital signal processor (DSP) of the playback device, where the calibration is permanently stored. The calibration can be stored in one of the preset locations, so that a comparison between activated optimisation and unchanged playback is possible at any time. The X-Room Calibration function can be used in parallel with the other sound settings.

Attention: For technical reasons, the calibration only works with current iOS devices using on-board tools. Android smartphones and tablets do not provide reliable measurement results due to the large number of microphones used with different parameters. The solution is the optional Nubert XRC Android Interface: a compact plug-in module that connects to the USB input (type C) of the mobile device and gives the X-Remote app access to a precise measurement microphone and a sophisticated analogue-to-digital converter. With this handy USB dongle, the XRC system's measurement tone or room response can be accurately captured, and then the app can calculate the optimal correction curve and transmit it to the signal processor. Further information on the application can be found in the manual.
