configuration options

• The ampX offers a variety of possible applications.
• Depending on the desired application, different configurations can be selected in the setup submenu .

setup > single

• This is the default configuration.
• Passive speakers are connected to the speaker terminals of the ampX. Optionally, an active subwoofer can also be connected to the SUB Out socket using a cinch cable.
• The ampX always allows wireless music reception via Bluetooth and control of the ampX from your smartphone.
• The wireless music transmission to other Nubert devices in the Nubert Wireless System is deactivated. The standby power consumption is less than 1 watt.

setup > wls slave
In this configuration, the ampX offers the same range of functions as in the single configuration. In addition, the reception of music signals from the Nubert Wireless System is activated. To do this, the ampX as a slave must be connected to a corresponding wls master as a transmitter. Please refer to the setup section on page 11 and the transmitter’s operating instructions. The ampX remains fully operable. The wireless signal received is provided at the wireless (wls) input and can be selected like any other source. The volume is adjusted independently of the master device. With the radio module activated, the stand-by power consumption is less than 2 watts.

setup > wls master

• The range of functions of the single configuration is also retained in this configuration. In addition, the transmission of music signals to other devices with the Nubert Wireless

• System is activated. To do this, the ampX must be connected as a master to a corresponding wls slave . Please refer to the setup section on page 11 and the
  receiver’s operating instructions.

• With the radio module activated, the stand-by power consumption is less than 2 watts. In this configuration, it is not possible to receive music signals from the Nubert Wireless System.

• Example: Controlling wirelessly connected active speakers The ampX can be used as a control device to control nuPro X active loudspeakers (and nuSub subwoofers) and to supply audio signals wirelessly. The source devices are all connected to the ampX, which avoids unnecessary cable routes to the active speakers. The appropriate channel (left, right or mono) is selected on the nuPro X active speakers before it is configured as a wls slave .

• Example: Multiple listening zones (volume adjustment zone ctrl) In addition to the passive loudspeakers connected locally via cable, compatible loudspeakers or devices can be connected wirelessly to transmit the music to other rooms or areas. The volume of the wirelessly connected devices is always controlled together with the volume of the locally connected passive speakers. The relative volume level of the slave speakers can be adjusted in the zone ctrl submenu (see page 11).

Connections and signal inputs

• The nuConnect ampX is completely wired before switching on, see also our separate commissioning brochure.
• Using the remote control or the Nubert X-Remote app, select from the input sources which of the connected devices you want to hear.

Bluetooth input
The connection options of a nuConnect ampX also include wireless Bluetooth input selection for wireless music transmission from a smartphone, tablet or similar device.

Connections, signal outputs

speaker terminals
For connecting passive loudspeakers.

• Danger! Make sure that the bare wires of the connection cables do not touch each other or other metal parts of the housing! Be sure to observe the correct polarity when wiring.
• If you accidentally swapped the plus and minus poles of one of the channels, this will not cause any technical damage, but you will get a completely diffuse and weak-bass sound pattern in which it is no longer possible to locate the center.
• If you use cables without attached adapter plugs, the ends of the cables must be stripped of approx. 10 mm of insulation and twisted so that no individual wires protrude (danger of short circuits!). The bare end of the cable can now be inserted into the screwed-on cable clamp from the side. Then tighten the screw connections again sufficiently! Alternatively, banana plugs from the Nubert range of accessories can also be used. Holes are provided in the screw terminals for convenient connection of these plugs. This allows them to be plugged directly into the sockets after the protective plastic covers have been removed from the holes.

USB port on computers
Select the USB input.

Windows 10

Automatic setup
Connect the nuConnect ampX using a suitable USB cable (included) and switch it on. Windows normally installs the appropriate driver automatically and sets the ampX as the new default playback device. The setup is now usually complete.

Manual playback device selection
If the ampX has not been automatically set as the currently active playback device, or if you want to change the playback device manually, you can do this in the following ways:

1. By clicking on the speaker icon in the taskbar. You can see the currently active playback device above the volume control. You can click on this and switch to the nubert xCore USB Audio device .

2. In the Windows settings under

3. System

4. Sound
   you will find the corresponding drop-down menu for device selection.

Manual selection of output format in common mode
Windows allows you to specify the output format in which music data is passed on to the USB-DAC in shared mode.

• Open Windows Settings and navigate to
  • System
  • Sound
  • Device Properties >
• Additional Device Properties
  • Advanced tab
• The standard format can be specified here.

Note: This does not affect the playback of applications that work in exclusive mode. Here the playback format is determined by the application.

Manual driver installation
As an alternative to the Windows driver, you can also download a suitable driver from https://www.nubert.de/downloads/61/ and install it.

macOS

Automatic setup
Connect the nuConnect ampX and the computer using the included USB cable and turn it on. macOS normally installs the appropriate driver automatically and sets the ampX as the new default device for sound output.

Manual selection of the sound output device
If the ampX is not automatically set as the currently active device for sound output, or if you want to change the playback device manually, you can do this as follows:
In the system settings navigate to

• Hardware
• Ton
• output

Select the nubert xCore USB Audio item from the list of available audio devices .

remote control

The remote control of the nuConnect ampX allows direct access to the functions that are constantly required:

on/off

• Use the on/off button to activate the ampX or switch it to stand-by mode.
• If the ampX has been put into stand-by mode using the remote control or app, the automatic switch-on is deactivated.

volume and x (mute)

• The volume can be adjusted using the volume buttons. The x button mutes and unmutes . Please also note the Mute Functionality section on page 14!

tone

• The remote control also allows an uncomplicated adjustment of the sound character.
• The tone button calls up the corresponding menu and also allows switching between the submenus bass, mid/high and loudness.
• The two arrow keys above tone level can be used to make settings in the
• relevant submenu, such as increasing or decreasing the bass intensity or adjusting the mid/high range by up to +/- 10 dB. In addition, the loudness effect can be activated or deactivated. More on this in the sections Tone Balance and Loudness on page 14.

wide

• The wide button is used to select the strength of the wide effect between 0 (deactivated) and 4 (maximum) by repeatedly pressing the button. See the Virtual Stereo Stage Expansion section on page 14 for details on this particular DSP circuit that results in greater spatiality and wider stage imaging .

analog, wls, coax, opto, (bluetooth) und usb
These six buttons are used to select the source and some have double assignments. Repeated presses toggle between the two sources indicated:

p1 p2 p3
With these buttons you can call up 3 presets directly, which you can make and save in the setup. Alternatively, a preset can be saved by pressing and holding the respective button (see also page 12).

Remote control signals nuPro X series and nuConnect ampX

• The remote control signals from the nuPro active speakers and the ampX do not affect each other. This means that combinations of these systems can also be operated without triggering unwanted operations.
• However, the nuPro XS Soundbase uses the same remote control as the ampX. It is therefore not recommended to operate these two devices in the same room.

Nubert X-Remote App for comprehensive control and room correction

• As an alternative to the remote control, you can also use the Nubert X-Remote app for control, which you can download to your mobile device free of charge via the App Store or Play Store.
• With the X-Remote app, all settings of the nuConnect ampX can be made conveniently from the listening position. This applies in particular to the automatic room calibration using X -Room Calibration. Room influences often cause interference such as droning or dips in the low-frequency range.
• The X-Room Calibration enables the frequency response in the low-frequency range to be optimized using the integrated signal processor, thus ensuring an optimal listening experience with powerful, dry and impulse-true bass.
• To do this, simply start the calibration procedure of the app from the listening position. The ampX with the speakers connected now plays back the test noise, which is recorded via the microphone on your smartphone. Based on this measurement data, the app adjusts the frequency curve of the playback so that you can enjoy the optimal sound image at the listening position. You can switch the room correction on or off as you wish.
• A notice:
  The X-Room Calibration only affects the frequency response of the speakers connected to the speaker terminals. Sub woofers, like wirelessly controlled speakers, are not affected.

Note on entering a password:

• You may be prompted to enter a password the first time you connect the app to a compatible device.
• In the factory setting, the 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.

Note: After settings have been made, the display automatically changes to the permanent operating display of the volume or the ampX logo after 10 seconds. With this change, all settings made are saved. However, if the ampX is disconnected from the power supply before it is automatically saved, it will load the last saved settings when it restarts.

construction and technology

• sound balance
  The middle/high adjustment shows the characteristics of a so-called “sound balance” with the ampX. While commercially available treble controls “bend” the frequency response and thus produce over-emphasis in the sound, the frequency response of this controller continuously falls or rises linearly. This means that the basic tonal character of the speaker and the harmony of the sound image are perfectly preserved. The Mid/Hi tone control allows the frequency response to be raised or lowered with a maximum of 10dB at 20kHz.

• Analog gain
  The input sensitivity for the analog AUX input can be adjusted in 2 stages (0 dB / +6 dB).

• digital signal processing
  In favor of maximum signal purity, the signal path remains digital as far as technically possible. The signal that is played back is passed over the shortest possible route to a digital signal processor (DSP), which takes over the frequency distribution and optimization of the frequency response. It is also passed on to the amplifier modules digitally, so that maximum freedom from noise and signal precision can be guaranteed.

• Tonformat
  The ampX processes signals at the digital inputs in PCM format. It may therefore be necessary to adjust players such as TV sets or game consoles appropriately. To do this, select PCM as the output format in the player menu . Please also note the manual for your player.

• Turn off wirelessly connected systems

  • ampX as master:
    If the ampX switches to stand-by mode (due to the automatic switch-off or manually with the remote control or Nubert X-Remote app), all slave devices connected to it wirelessly follow suit automatically.

  • ampX als Slave:
    If the ampX is configured as a wls slave , for example to receive music from another room via the wireless input, it automatically switches to stand-by mode as soon as the transmitter switches to stand-by mode (requirement: The input selected on the ampX is wireless ).

  • When the transmitter is switched on again, a previously paired ampX does not wake up from stand-by mode at the same time. This avoids accidentally activating an ampX in another room.

• signal turnaround time
  The ampX has a very low signal throughput time of 5.8 ms in the setup as a single and in the setup as a wls slave. If the device is configured as a wls master , the signal throughput time increases to 25.7 ms. This ensures that the audio signal from locally connected speakers and wirelessly connected devices is played in sync.

• mute functionality

  • Locally connected speakers and wirelessly connected speakers and devices can be permanently muted independently. To do this, call up the zone ctrl submenu and select the respective devices there.
  • The xMute button on the remote control can be used to temporarily mute the playback device (local spk or wireless) in whose submenu the settings were last made. In the delivery state, the xMute button on the remote control operates the locally connected loudspeakers.

Virtual extension of the stereo stage
A complex DSP algorithm calculates additional spatial information in the ampX, which can be added to the audio signal.

This leads to the virtual expansion of the stereo stage. This effect can be set in four stages via the menu or remote control:

• When set to 0, the effect is disabled.
• When set to “1,” this effect is more gentle.  At “4”, the additional room information is most added; This mode is particularly recommended when a very effective sound image is desired where the focus is no longer on the precision of the location.

Note: This effect is only played through the locally connected speakers.

Automatic switch-off
The ampX has an auto power off feature that can be disabled in the menu. If one of the inputs AUX
or Bluetooth is selected, it switches to stand-by mode after no more than 20 minutes without a signal. With all digital inputs, it reacts directly to the absence of a digital data stream or the absence of the supply voltage at the USB input. This means that it can be switched off more quickly. The standby power consumption depends on the operating mode, see page 11, section setup.

Notes:
The playback devices on the SPDIF inputs must deactivate the data stream accordingly. If you want to use the automatic switch-off in conjunction with the USB input, you must select a USB socket on the player that does not have a permanent voltage.

Automatic switch-on

• The electronics of the ampX have an automatic switch-on function that can wake it up automatically from stand-by mode. This function is only active if the ampX has been put into stand-by mode by the automatic switch-off. The signal must be present at the input that was selected during the automatic switch-off process. (This function is not for Bluetooth devices or available at the wireless input.)
• Was the stand-by mode manually by pressing the on/ off button on the remote control or the app, the automatic switch-on is deactivated.

Loudness
With this function, a volume-dependent frequency response correction can be made that is modeled on the character of human hearing. This perceives basses less strongly at low volumes. In order to achieve a full-fledged sound image even at low volumes, low frequencies can be automatically boosted by up to 10 dB by activating the loudness function.
