• Do not change the serial number on the speaker. It is part of the operating approval.
• If the loudspeaker is repaired or modified by workshops or other third parties not authorized by
Nubert, it loses its operating license.
• Only accessories and devices may be connected which in turn comply with all legal requirements
and are approved.
• This device may only be used for the applications specified in the „Intended Use“ section.
Coldness, Sound and Dependability .
When loudspeakers and other electric devices are brought from a cold into a warm
environment, it is possible that there will arise water condensation inside. In conse-
quence of that, there exists danger of any defects or an electric shock. Furthermore,
deep temperatures will have an impact on the flexibility of movable parts inside of the
loudspeaker.
2
Therefore, wait at least 4 hours before turning on the device until it has taken room
temperature. Your new Nubert loudspeaker will thank you with the superior sound qual-
ity you’re expecting from Nubert rightly.
Intended Use .
This electric device is designed exclusively for sound reproduction in dry rooms. Use
the receiver only as described in this manual. Any other use (particularly safety-rele-
vant or medical use, installation in open environment like IP-certified products) is con-
sidered 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.
Positioning and Antenna .
The nuXinema must be
placed on a flat and stable
place. Be careful that there
will be a sufficient air circu-
lation for cooling the device
during operation.
On the back side, the
nuXinema has two threaded
bushes for antennas. Install
the antennas (included in
the standard delivery) and
align them towards the top.
Connections and Application Examples
The nuXinema must be wired completely before switching on – please look at the
separately installation guide for more details.

stores (Google Play and Apple).
With the X-Remote App you can control all options and settings from your listening
position very comfortable. The app includes all menu points which are also available
6
by the display at the front of the nuXinema. Additionally, there are some more functions
available as follows:
Setting password
If necessary, you may request to set a password when the app will be loaded firstly. By
the factory setting, the password is set at the value 0000.
In the menu
>Settings >advanced >password
it is possible to set another password to protect your device from unauthorized access.
If the device will be reset to factory defaults, the password will also reset to the value
0000.
X-Room Calibration
Bad room acoustics can have a negative effect of the final sound, for e.g., such as
droning noise or losses at low frequencies. Specifically targeting the sound means that
unwanted room reflections can be avoided.
X-Room Calibration allows an optimization of lower frequencies so that the bass
sound will have a punchy sound and better pulse accuracy. To benefit from these au-
tomatically room calibration, it is necessary to connect with every compatible loud-
speaker separately and pass this calibration process from your listening position.
The loudspeaker will activate a test noise which will be recorded by your smartphone
microphone. The app will use this data to calculate a correction curve which will be
send back to the speaker, so that you could enjoy the best sound at your listening po-
sition. In addition, the nuXinema preAV can optimize the lower frequencies of the front
speaker connected by cinch by means of its integrated signal processor.
⚠ Notice:
▪ When using an Android mobile phone, there is necessary the separately USB meas-
uring microphone “Nubert XRC Android Interface” to use the X-Room Calibration func-
tion.

Construction and technology
Sound balance
The mid/high frequency adjustment of the nuXinema preAV has the characteristic of
a commonly called "sound balance". While conventional treble controls "bend" the fre-
quency response and thus create sonic overemphasis, the frequency response with
this controller rises or falls continuously in a linear manner. Thus, the basic tonal char-
acter of the loudspeakers as well as the harmony of the sound image are perfectly
preserved. The Mid/Hi tone control allows the frequency response to be increased or
decreased with a maximum of 10 dB at 20 kHz.
Analog gain
The input sensitivity for the analogue AUX input can be set in 2 steps (0 dB to +6 db).
Sound format
The nuXinema preAV handles various audio formats in de digital input like
• PCM (up to 192 kHz / 24bit)
• Dolby Audio
• Dolby Atmos
• DTS
• DTS X
If the nuXinema preAV is connected by HDMI eARC, the compatibility will be often
identified automatically so that the TV outputs the appropriate signal (the CEC function
in the TV must be activated). In some cases, it may be possible to adjust players such
as TVs or game consoles to the right settings manually. For the highest possible com-
patibility, it can also be useful to specify PCM as the sound output format. Please also
refer to the manual of your player.
Operating mode: X-Connect activated
For connecting some speakers or devices by wireless network X-Connect Surround,
choose the option > ch config in the main menu. Navigate to your desired channel and
choose the option > new pairing. The wireless network is activated automatically.
The standby power consumption in this mode is <2.0 watts.
Operating mode: X-Connect deactivated
To deactivate the wireless network (X-Connect Surround), set all the entries in the
menu section > ch config to > none or > pre out. The wireless network is deactivated
automatically. The standby power consumption in this mode is <1.0 watt.
This is also the factory default.
Signal turnaround time
The nuXinema preAV's signal turnaround time is a minimum of 30.5 ms. The sound
signal is always reproduced synchronously from all speakers connected via analogue
output or speakers connected via X-Connect Surround. To adapt the sound reproduc-
tion to the picture reproduction of your TV set, the signal can be additionally delayed
up to 400 ms. delay. Please refer to the lip sync section on page 11.
15
Automatic switch-off
The nuXinema preAV is equipped with an automatically switch-off function which can
be deactivated in the menu. If there is selected one of the inputs AUX or Bluetooth, the
loudspeaker will turn into stand-by mode automatically after 20 minutes without sig-
nal. For all digital inputs it also reacts directly to the absence of a digital data stream
or a switch-off command at the HMDI ports. Thus, a faster switch-off is possible if the
playback devices at the SPDIF inputs deactivate the data stream accordingly.
Automatic switch on
The nuXinema preAV also has an auto power on feature that can automatically wake
it up from stand-by mode. This function is only active if the loudspeaker has been set
to stand-by mode by the automatic switch-off. The signal must be applied to the input
that was selected during the automatic switch-off process. (This function is not avail-
able for Bluetooth devices). If the standby mode was activated manually by pressing
the on/off button on the remote control or the app, the automatic switch-on function
is deactivated.
Loudness
With this function, a volume-dependent frequency response correction can be made,
which is based on the character of the human auditory system. The human ear per-
ceives bass at low volumes perceived less strongly at low volumes. To achieve a full
sound image even at low volumes, low frequencies can be automatically boosted by
up to 10 dB by activating the loudness function.
Frequency response correction of the loudness circuit
Extension of a Surround Setup via X-Connect Surround
The nuXinema offers two options for connecting some loudspeakers:
In standard mode, 8 channels can be connected analog via RCA cable, so that a maxi-
mum of a 5.1.2 setup can be set up.
In wireless mode, additional 8 channels can be connected wirelessly via X-Connect
Surround. A maximum 7.1.4 setup can be set up with a combination of wired and wire-
less speakers. The configuration of such a setup can be done via menu on the device,
in the on-screen menu or via the app. Please refer to the corresponding sections in
these operating instructions and also the commissioning instructions.
16
Please note about the channels connected via X-Connect Surround:
The preAV reacts flexibly to the currently available speakers and automatically adjusts
the corresponding output channels. If, for example, the speakers used for the rear
channels are switched off (e.g., at the power switch on the back of the device or via an
app), the preAV detects this and modifies the upmixing in such a way that the sound
components to be output there are then redirected proportionally to other speakers
that are still present.
Sound and Surround modes
The nuXinema preAV features several different sound and surround modes. These can
be selected via the mode button on the remote control. The incoming sound signal is
processed by the internal signal processor – partly according to Dolby or DTS specifi-
cations, partly according to Nubert's own algorithms. The sound output is as follows:
stereo
The sound output only is via the two front channels. Stereo content is played back
directly, multi-channel content is mixed to the two front channels. No sound pro-
cessing takes place.
movie, music, voice+ and night
Any source material will always be played back through all available loudspeakers in-
cluding height speakers. Native Dolby Atmos or DTS X material is reproduced true to
its channel.
If upmixing takes place, it is automatically adjusted to the currently used speaker
setup. Depending on the input signal algorithms from Dolby or DTS are used.
movie For full movie enjoyment through all available speakers
music For full music enjoyment through all available speakers
voice+ Complements Nubert's own optimization voice+ for best speech intelli-
gibility
night For full sound enjoyment at night
auto Automatic detection of the input signal and up mixing or direct playback
on the appropriate existing channels.
