Nubert nuPro XS-7500 - Soundbase Manual

Unpacking and Scope of Delivery

Unpacking
Avoid using sharp or pointed objects when unpacking your speakers. Please keep the packaging in a safe place in case you need to transport the speaker at a later date.

Scope of delivery
If the delivery is complete, it contains the following parts:

• 1 nuPro soundbase
• 1 Cloth grille
• 2 Out-rigger feet
• 1 Mounting kit (4 bolts, 1 hex key)
• 1 Remote control with battery
• 1 Mains cable, 3 m
• 1 HDMI ARC adapter
• Signal cables:
  • Stereo jack cinch cable (3.5 mm jack cinch), 1.5 m
  • Fibre optic cable with TOS-Link plugs, 1.5 m
  • USB cable (Type A/Type B), 1.5 m

Mounting the out-rigger feet

Be careful not to scratch the loudspeaker! Don't let any items fall into the bass reflex ports!
Place the speaker upside down on a soft, non-scratching surface! Place the out-rigger feet over the threaded bushings as shown in the picture and mount the feet securely with the supplied bolts and hex key. You can now turn the loudspeaker around, place it on its feet and adjust the mini-spikes for a level, stable stand.

Mounting kit with one pair of out-rigger feet

Standard mounting: out-rigger feet pointing outwards

Alternative mounting: out-rigger feet pointing inwards.
This method is recommended if the XS-7500 needs to be placed on a narrow surface or if heavy objects (more than 50 kg's) needs to be placed on the soundbase.

Low temperatures and Sound

When speakers are shipped and delivered during the cold months of the year, it is imperative that they adapt to the temperature of the living area. Low temperatures have a considerable influence on the moving parts of a loudspeaker such as diaphragm, voice coil, bead and spider. The ability of these components to follow rapid oscillations or to perform large excursions is thus significantly restricted. This is not dangerous, but "frozen" speakers are far from their acoustic peak.
Hence our tip: When your new speakers arrive on a cold winter's day, just give them a few hours to acclimatise. Your Nubert speakers will thank you with the superior sound quality you have come to expect from us.

Cloth grille

The cloth grille protects the loudspeaker drivers (for example from curious children who like to press in tweeter domes) and provides a visual contrast for those who do not like the technical appearance of loudspeaker drivers. It is carefully placed against the front of the speaker and held in place magnetically. Please make sure that the surface of the baffle is not damaged.
With the cloth grill removed, the loudspeaker sounds somewhat brighter and clearer - the choice is yours!

Setup

The nuPro-soundboard XS-7500 is a high-quality, very neutral active stereo loudspeaker. They impress with an extremely homogeneous, precise, and "direct" sound reproduction with the finest resolution in the entire frequency spectrum. However, even an "honest loudspeaker" is exposed to the manifold influences of room acoustics. In order to achieve the most natural and true-to-life reproduction possible, please observe the following general installation guidelines:
Due to the rear-facing bass reflex ports, the XS-7500 should be placed at least 5 centimetres from the rear wall in order to ensure trouble-free operation and to avoid air flow noises. Some distance to the back- and side walls also helps prevent an increase in the bass- and fundamental ranges. When placed on a shelf, the best sound is achieved when the front edge of the speaker is either flush with the shelf or protrudes slightly. This allows the loudspeaker to radiate the sound freely into the room and helps to avoid voices sounding like coming through a funnel.

Ideal horizontal listening area
The best listening experience is achieved directly in front of the XS- 7500. If you often need to sit off-centre and thus outside the optimum listening area, we recommend that you compensate with the sound controls.

Placing the speaker at the optimum height
The most natural sound is achieved when the tweeters are approximately at ear level. But even 30 degrees above or below the tweeter axis, the sound is still homogeneous. If the XS-7500 is placed directly beneath your TV, you will in most cases be within the optimum listening area already. If the speaker needs to be placed lower or higher, it should ideally be angled so that the tweeters are aimed at the listening position. If this is not possible, we recommend compensating with the sound-controls.

Connections and application examples

All cables must be connected to the nuPro Soundbase before switching it on, see also our separate Quick Start Guide. Using the remote control or the Nubert X-Remote App, you can select which of the connected devices you want to hear from the input sources.

Bluetooth
The connection options of a nuPro X loudspeaker also include a Bluetooth input for wireless music transmission from a smartphone, tablet, or similar device.

Wireless input
Connect another compatible Nubert appliance wirelessly, for instance nuPro X active speakers nuConnect ampX amplifier

USB-connection to a computer

Select the USB input on the nuPro master-loudspeaker.

Remote control

The remote control of the nuPro allows direct access to the permanently required functions:

p1 · p2 · p3
With these buttons you can directly recall 3 presets, which you can make and save in the setup. Alternatively, a preset can be stored by pressing and holding the respective button.

nuPro X loudspeakers and nuPro soundboards Remote control signals
The remote control signals from the nuPro Active speakers and soundbars do not interfere with each other, making it possible to use combinations of speakers and soundbars simultaneously without accidentally operating the wrong speaker.

Nubert X-Remote App

As an alternative to the remote control, you can also control the nuPro X-Series speakers with the Nubert X-Remote App, downloadable to your mobile device free of charge via the App Store or Play Store.


It offers the possibility to easily adjust all settings of the active loudspeakers comfortably from the listening position.
The app is intuitive and easy to use thanks to easy-to-understand graphics.
With the X-Remote App, you can adjust all settings of the nuPro X-series from the comfort of your listening position. This is particularly useful when using the X-Room Calibration function. Room influences often cause problems such as boominess or dips in the low-frequency range. The X-Room Calibration algorithm utilizes the powerful DSP of the nuPro X-series to optimize the frequency response in the low frequency range for an optimal listening experience with precise, dynamic bass.
Simply start the measuring procedure in the app from the listening position. The speakers now play a test tone which is picked up by the microphone of your smartphone. Based on the measured data, the app analyzes and adjusts the low frequency response of the loudspeakers so that you can enjoy optimal sound quality at the listening position. You can switch the room correction on or off.
Attention: At present, the X-Room Calibration feature is iOS compatible only.

Password entry:
The first time you pair the X-remote app with a nuPro X device, you will be prompted to enter a password. The default password is 0000. A different password can be assigned in the menu to protect the device from unauthorized access. If the device is reset to the factory settings (default), the password is also reset to 0000.

Wireless sound transmission between Nubert Wireless System products

Nubert X-platform based speakers and appliances can wirelessly exchange audio- and control-information. These include nuPro X loudspeakers, nuSub XW subwoofers and the nuConnect amplifier. The appliance that transmits the signal is the Master, the receiving appliances are the Slaves. In some appliances this is preconfigured, others like the XS-7500 can be flexibly configured. Please refer to the section Setup.
Depending on which appliance is receiving the signal, please observe the following:

1. Receiver: nuSub XW
   Nubert XW-generation subwoofers are always preconfigured as slaves (wls slave).
   • The Master appliance always transmits a full-range signal. Accord-ingly, crossover frequency and relative level must be set on the subwoofer.
   • The overall level is adjusted on the Master-appliance.
2. Receiver: nuPro XS-7500 or nuConnect ampX The nuPro XS-7500 and the nuConnect ampX remain independently controllable in wls slave mode.
   • The received signal is accessed by selecting the wireless (wls) input.
   • Level is set on the receiving device, independently of the Master- appliance.
3. Receiver: nuPro X loudspeaker Transmitter: nuPro XS-7500 or nuConnect ampX
   No changes can be made to the configuration on the nuPro-X speaker once it is set to wls slave.
   • Selecting the correct channel (left, right or mono) must be donebefore the wls slave mode is selected, as no channel configuration information is transmitted from the master-appliance.
   • The relative level of the slave-loudspeaker(s) can be adjusted in the sub-menu zone ctrl on the XS-7500 or nuConnect ampX. Please refer to the section zone ctrl.
   • The overall level is controlled from the Master-appliance.
4. Receiver: nuPro X loudspeaker Transmitter: nuPro X loudspeaker
   In this most common configuration (see the owner's manual for your nuPro X speakers), all settings are made on the Master-loudspeaker.
   No changes can be made to the configuration on the nuPro X speaker set as wls slave, including level and channel selection.

Further use cases

Augmentation through a pair of nuPro-X loudspeakers (i.e. X-4000 or X-8000)
The nuPro Soundbase can be supported by a pair of loudspeakers from the X-series in order to achieve a broader stereo image. The loudspeakers are placed in the classic stereo triangle and connected wirelessly to the soundbase.
Set the corresponding channel, left or right, in the channel menu on the loudspeakers you want to add. Now connect the speakers to soundbase by selecting wls master in the setup menu of the soundbase and wls slave on both loudspeakers.
The complete, combined system can now be controlled from the soundbase. We recommend setting the soundbase to mono in the channel menu in order to achieve a more precise, central vocal reproduction.
The balance between the soundbase and the speakers can be adjusted in the zone ctrl menu on the soundbase. You can read more about the menus.

Use with a subwoofer
If you want to use your XS-7500 together with a wired subwoofer, you can connect it to the SUB Out output. This output provides the subwoofer with a low-pass filtered, summed mono signal. You can set the crossover frequency for the subwoofer in the menu advanced / subwoofer.
The cut-off frequency for XS-7500 is adjusted in the advanced / system-hp menu. The relative level of the subwoofer must be set on the subwoofer itself.
Alternatively, the subwoofer can be connected wirelessly. Please refer to the Receiver: nuSub XW chapter above.

Menu navigation and settings

Note: If no settings are made, the display automatically changes back to displaying the volume or the nuPro logo after 8 seconds. As the display changes, all settings made are automatically saved. However, if power is disconnected before the automatic saving takes place, the last saved settings will be loaded on restart.

Construction and technology

Tilt Control
The midrange/treble adjustment of the nuPro loudspeakers has the characteristics of a so-called "Tilt control". While standard treble controls "bend" the frequency response and thus produce colourations, this control continuously affects the frequency response in a linear fashion. This perfectly preserves the basic tonal character of the loudspeaker and the harmony of the sound image. The Mid/Hi tone control allows an increase or decrease of the frequency response with a maximum of 10 dB at 20 kHz.

Analog gain
The input sensitivity for the analog inputs XLR and AUX can be adjusted in 2 steps (0 dB / +6 dB).

Digital Signal Processing
For maximum fidelity, the signal path of a nuPro X loudspeaker is kept virtually entirely digital: Digital input signals go straight to the digital signal processor (DSP), which then handles frequency distribution and optimization of the frequency response. Analogue sources are first converted to a digital signal by high-quality A/D converters. The signal remains digital all the way into the power amplifiers in order to achieve the best possible precision and signal to noise ratio.

Sound format
The nuPro X loudspeakers process signals at the digital inputs in "PCM" format. It may therefore be necessary to adjust the settings of players such as TV sets or game consoles accordingly. To do this, select "PCM" as the output format in the playback menu. Please also refer to the manual of your source device.

Turning off multiple nuPro X loudspeakers
If the XS-7500 is switched into stand by either the remote or the auto-off function, all wirelessly connected loudspeakers are automatically set to stand by as well.

Switching off a nuPro X pair
If the master box is set to standby mode by either with the remote control or by the auto-off function, the other loudspeakers operate in PAIR mode follow automatically.

Latency
The nuPro X Soundbase has a very low latency of 7.6 ms when set up as single or wls slave. If the XS-7500 is used in the wls master configuration, the latency increases to 27.5 ms in order to assure correct time-alignment between the master- and slave loudspeaker.

Virtual sound-stage expansion
A complex DSP-algorithm calculates and extracts additional spatial information that can be added to the original signal. When added, the soundstage is virtually broadened and expanded. This effect can set to 4 different levels:

• Set to "0", the effect is deactivated
• Set to "1", the effect is soft
• Set to "4", the effect is the most pronounced. This setting is recommended when a very expansive soundstage is wanted and precise location is less important.

Auto-off function
The auto on/off function reacts differently, depending on the selected input: If no signal is present at the analog input, the loudspeaker is set to stand by after 20 minutes. As soon as an analog input signal is detected, the speaker switches back on. At the other inputs, the activity of the connected source is monitored, allowing the loudspeaker to switch off or on instantly. At the SPDIF, Optical, Port and AES/ EBU inputs, the presence of the digital data stream is monitored, while at at the USB input the presence of USB supply voltage is detected. The standby power consumption depends on the operating mode. See section setup.
Note: Modern computers often have USB sockets that deliver constant voltage (e.g. for charging a mobile phone) even when the computer is switched off. If you want to use the auto-on function of your nuPro active loudspeakers in conjunction with the USB input, you must use a USB connector that powers off with the computer.

Auto-on function
The nuPro speakers have an auto-on function that automatically wakes up the loudspeaker from standby mode. This function is only active if the loudspeaker was set to standby by the auto-off function. To wake up the loudspeaker, a signal must be present at the input that was selected when the loudspeaker went into standby (this function is not available for Bluetooth devices). If the speaker was set to standby using the remote control or the app, the auto-on function is disabled.

Loudness
This function can be used to make a volume-dependent frequency response correction that compensates for limitations in the human hearing. At low levels, human hearing is less sensitive in the bassrange. In order to compensate for this, the loudness function increases the bass-level with up to 10 dB when activated.

Care and cleaning tips

Improper handling of the speaker may result in damage.

• Always unplug the speaker before cleaning it!
• Before recommissioning, make sure that all connections are cor-rect, that there are no short circuits and that the speaker is completely dry.
• Never use strong cleaning agents or solvents such as petrol, spir-it or similar!

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. The tweeters of all Nubert loudspeakers are equipped with a protective grille so that they can also be wiped off with low pressure. If the dust cannot be completely removed, a make-up brush from the drugstore is suitable.
