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!

Out-rigger feet

nuPro floorstanding loudspeakers are delivered with removable out-rigger feet, these also ensures that the down-firing bass reflex ports have the required distance to the floor.

The loudspeaker cannot be used without the out-rigger feet being mounted, please read the included quick-start guide for mounting instructions.

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.

Setup

The nuPro X are high-quality, very neutral active stereo loudspeakers. They impress with an extremely homogeneous, precise, and "direct" sound reproduction with the finest resolution in the entire frequency spectrum. However, even "honest loudspeakers" are 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 instructions:

• The distance to rear- and sidewalls should ideally be as big as possible, we recommend at least half a meter. Some distance to the back- and side walls also helps prevent an increase in the bass- and fundamental ranges.
• If the bass reproduction is perceived as being too strong when the speakers are placed close to a wall, you can raise the lower cut-off frequency of the speakers, as described undersystem hp, and/or adjust the bass volume with the bass control as a "countermeasure".
• Within horizontal listening angles up to 30 degrees off the hori-zontal axis, you will experience no significant change or loss in sound quality. Only at wider listening angles does the sound lose its brightness slightly. It is then advisable to point the speakers towards the listening position.
• The most natural sound is achieved when the tweeters are ap-proximately at ear level. But even 20 degrees above or below the tweeter axis, the sound is still homogeneous. If your active speakers need to be placed lower or higher, they should ideally be angled so that the tweeters are aimed at the listening position.

Connections and application examples

Make sure that all connections to the nuPro loudspeakers are made before switching them 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.

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.
Please note:
For Android devices, the USB measurement microphone "Nubert XRC Android Interface" is required to use the X-Room Calibration.

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.

Configuring a stereo pair

All nuPro X loudspeakers have the same functions and the connections. Depending on placement and usage, configure your loudspeakers in one of the following ways.
Note: Always connect your sources to the master loudspeaker when using master/slave configurations! All settings are performed on the master loudspeaker using the control pad.
Default setting: Cabled connection, left speaker as Master Connect the two loudspeakers with the supplied SPDIF cable by plugging one end of the cable in to the Link Out connector on the left loudspeaker and the other end into the Coaxial 1 connector on the right loudspeaker. The left loudspeaker automatically configures itself as the Master and the right as the Slave. The loudspeaker pair is now configured and ready to use.
Variation: Cabled connection, right speaker as Master Connect the two loudspeakers with the supplied SPDIF cable by plugging one end of the cable in to the Link Out connector on the right loudspeaker and the other end into the Coaxial 1 connector on the left loudspeaker. The right loudspeaker automatically configures itself as the Master and the left as the Slave.
Go to the channel menu on the Master loudspeaker and set the channel to right ch, the master loudspeaker will now play back the right channel. The Slave loudspeaker is configured automatically and will now play back the left channel.
Variation: Wireless connection, left speaker as Master In the setup menu of the left speaker, select wls master and confirm with . On the right speaker you then select wls slave and confirm. The loudspeakers will then connect to each other and the left loudspeaker will now be the Master loudspeaker.
Variation: Wireless connection, right speaker as Master In the setup menu of the right speaker, select wls master and confirm with . On the left speaker you then select wls slave and confirm. The right loudspeaker automatically configures itself as the Master and the left as the Slave. Go to the channel menu on the Master loudspeaker and set the channel to right ch, the master loudspeaker will now play back the right channel. The Slave loudspeaker is configured automatically and will now play back the left channel.
Variation: individual configuration, wired connection This option is recommended when the loudspeakers are used with an external preamplifier. In the setup menu of each loudspeaker, select single and confirm. This way, each loudspeaker can configured independently and receive separate audio signals.

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.

Time correction
Due to the digital signal processing, every nuPro X loudspeaker has a small delay of the sound signal. If the nuPro speakers are operated as a stereo pair in the PAIR configuration, any time differences between the speakers are automatically compensated so that the left and right signals are reproduced at exactly the same time. The result is the best possible spatial reproduction with precise voice positioning.

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.

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.

HDMI ARC Adapter
At the USB-Port input you can connect, among other things, an HDMI ARC adapter. This adapter makes it possible to send audio- and control information (e.g. level) from a compatible TV to your nuPro Speakers. The HDMI REQ key initializes the HDMI CEC functions on older TVs. On newer TVs, this is normally not necessary. Note: The HDMI output of the source (TV) must support The HDMI ARC protocol!

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.

Frequency response correction relative to volume settings

Further Applications

Connecting a subwoofer
If you wish to connect a subwoofer to your nuPros, you have two options:
You can connect your subwoofer at the SUB-output of the Master loudspeaker. This output outputs a lowpassed, summed mono signal. You can set the crossover-frequency in the advanced / subwoofer menu.
Alternatively, you can connect a subwoofer, e.g. from our nuSub series, wirelessly by connecting it as a wls slave. Because the Master-speaker outputs a fullrange wireless signal, the frequency of the lowpass-filter must be set on the subwoofer itself. Please see the operating manual of your subwoofer.
In both cases, the highpass crossover frequency of the nuPro speakers is set in the system hp menu of the Master speaker. The relative level of the subwoofer is set on the sub.

Connecting a nuPro pair to a preamplifier
In addition to connecting a preamplifier to a nuPro pair in master-slave mode, an external preamplifier can also be connected directly to the individual nuPro active loudspeakers. As with conventional active loudspeakers without master-slave functionality, the boxes can then be configured independently of each other. Connect the output of the left channel of your preamplifier to the nuPro on the left and the output of the right channel to the nuPro on the right.
Note: Connect the output from your preamplifier to the AUX L input on each nuPro X speaker. Do not connect the speakers to each other with the SPDIF coaxial cable.

Use of a single nuPro
Each nuPro X loudspeaker can play either the left or right channel, or a summed mono signal. This can be selected in the channel menu.

Using multiple nuPros
If you need to supply multiple nuPros with the same signal, connecting the speakers wirelessly is the obvious solution. A Master loudspeaker can feed the signal to an almost unlimited number of slave-speakers. It is also possible to mix different types of loudspeakers.
Especially in this kind of party-mode we recommend to set the master loudspeaker to mono in the channel menu. This way, all nuPros will get the same summed mono signal.
You can also configure all loudspeakers as single if you need to configure each loudspeaker individually. The loudspeakers must be connected to each other with a coaxial cable in order to pass the SPDIF signal on to the next loudspeaker.

Surround-sound setups
You can create complex surround sound setups with the nuPro X-series loudspeakers.
Just like in a conventional system with passive loudspeakers, an AV-receiver or AV-preamplifier is the heart of the system; the main difference being that the nuPros are not connected to the loudspeaker terminals but to the preamplifier line-outputs.
An example: Thanks to the wireless capabilities of the nuPro X series you only need signal-cables for the front loudspeakers, the surround loudspeakers can be connected wirelessly! This way you save laying loudspeaker cables in your living room.

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.
