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 ([email protected])! Danger of suffocation! Never let children use or play with neither 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 ([email protected]) immediately! • The speaker has been damaged or has fallen down. • Power cord or plug is damaged • Objects or liquid have got 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 per- formance. • The loudspeaker smells burnt, develops smoke or makes unusual noises. Caution! The drivers built into this loudspeaker generate a strong magnetic field in their immediate vicinity, which can impair or damage other devices. It is therefore essential to keep magnetically sensitive devices away from this loudspeaker! Do not place tube screens, notebooks, hard disks or the like on the speaker! Only use accessories recommended by Nubert! Low temperatures and Sound When speakers are shipped and delivered during the cold monthsof 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 loud- speaker 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. 2 nuPro AS-250 · 4/2020 EN Thank you for purchasing a nuPro active loudspeaker! If you read this manual carefully, setting up your new speaker is quick and easy. We will explain the setup, the connections, and the daily operation so you can achieve the best possible sound quality and get the most out your new nuPro loudspeaker. The Nubert team wishes you many hours of musical enjoyment!

• Only place the loudspeaker on a flat, stable surface and make sure that it cannot be knocked over! • Also make sure that no unintentional pulling can occur on the cables to avoid knocking over the speaker or damaging the connection sockets! • Keep strong mechanical shocks away from the loudspeaker! Caution! Excessive heat build-up inside the unit can shorten its service life or lead to fire. • Never cover the back of the speaker! Make sure that there is a clearance of at least 10 cm and sufficient air circulation in the back area! • Do not operate the speaker and remote control near heat sources such as radiators or stoves! • Do not set the speaker and remote control to direct sunlight. • Do not expose to direct sunlight! • Never place burning candles or similar open fire sources on the loudspeaker! Danger of explosion! Installation in unsuitable locations can cause explosions. Do not use the speaker or remote control • in environments where there is a risk of fire or explosion! • at extremely low or extremely high temperatures! • near flammable gases or vapours! • near strong dust! • near flammable materials! Danger of electric shock! The loudspeaker carries mains voltage and voltages higher than 35 V AC or DC inside. It has no special protection against the intrusion of liquids or objects into the system. There is therefore a risk of lethal electric shock. • Never touch the speaker with wet hands! • Only use the speaker in a dry place! • Do not operate it outdoors or in damp rooms! • The loudspeaker must be protected from liquids of all kinds, including dripping and splashing water. • Do not place any containers containing liquids (e.g. flower vases) on the speak- er or in the immediate vicinity! • If the loudspeaker is moved from a cold environment to a warm room, conden- sation may form inside the unit. Wait at least six hours until the loudspeaker has reached room temperature and is dry before switching it on! • No objects or foreign bodies may get into the device. • Should the loudspeaker come into contact with liquids or should objects have got inside, please unplug the mains plug immediately and contact Nubert elec- tronic GmbH ([email protected])! Danger of injury or damage! For speakers with threaded bushings on the underside: The threaded bushings may be used for upright mounting of the loudspeaker on suitable base plates only. The threaded bushings on the underside of the loud- speaker enclosures are not designed for tensile loads and must therefore not be used as holders for hooks or similar devices in order to suspend the loudspeaker cabinet. A falling speaker may cause serious injury and damage. Connection instructions General connection instructions • Disconnect the mains plug before changing any wiring on the system! • Make sure that all connections have been made correctly and that all plugs are firmly seated in the sockets before connecting the speaker to the mains. • Use only the intended cables or plug connections for the connections! Failure to do so may result in damage or malfunction. • If you want to disconnect connections on the loudspeaker, always pull the plug, never the cable! • Ensure that all plugs are firmly seated in the sockets! • Only use cables and accessories recommended by Nubert!

Stereo jack cinch cable (3.5 mm jack cinch), 1.5 m Unpacking and Scope of Delivery Unpacking Avoid using sharp or pointed objects when unpacking your speak- ers. 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 AS-250 active stereoboard • 3 Cloth grilles • 1 Remote control with battery • 1 Mains cable, 2 m • 4 Signal cables: – SPDIF coaxial cable, 3 m – Stereo jack cinch cable (3.5 mm jack cinch), 1.5 m – Fibre optic cable with TOSLINK plugs, 1.5 m – USB cable (Type A/Type B), 1.5 m Setup The nuPro-soundboard AS-250 is a high-quality, very neutral active stereo loudspeaker. It impresses with an extremely homogeneous, precise, and “direct” sound reproduction with the finest resolution in the entire frequency spectrum. However, even an “honest loud- speaker” 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 guide- lines: Due to the side-facing bass reflex ports and drivers, the AS-250 should be placed at least 5 centimetres from the side wall in order to ensure trouble-free operation and to avoid air flow noises. More 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 slight- ly. 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 AS- 250. If you often need to sit off-centre and thus outside the opti- mum 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 approxi- mately at ear level. But even 30 degrees above or below the tweet- er axis, the sound is still homogeneous. If the AS-250 is placed directly beneath your TV, you will in most cases be within the opti- mum listening area already. If the speaker needs to be placed low- er or higher, it should ideally be angled so that the tweeters are aimed at the listening position. If this is not possible, we recom- mend compensating with the sound-controls. 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 SPDIF coaxial cable, 3 m Fibre optic cable with TOSLINK plugs, 1.5 m USB cable (Type A/Type B), 1.5 m 1 Mains cable, 2 m Remote control with battery nuPro AS-250 Active Stereoboard with 2 grilles for the sides and 1 grille for the front

The AS-250 is a complete sound-system in a single cabinet. All cables must be connected before switching the AS-250 on. All source devices are connected on the back of the AS-250. Optionally, you can also connect an active subwoofer. Use the remote control select the source you wish to listen to. Power: Power connector and power switch Connect the supplied power cable to the power connector on the back of the AS-250. Using the power-switch to turn the AS-250 off removes all power to the AS-250. All settings remain stored. Note: You can also use an external, switchable extension cord to simplify the separation from the power grid. Stand-by Pressing  on the keypad on the front of the loudspeaker wakes it up from stand-by. Keeping the button pressed for 6 seconds will set the speaker to stand-by. Alternatively, this switching operation can also be performed using the either remote control (see page 7) or the automatic stand-by function (see page 8, section AUTO). n USB port The USB-port provides 5 V/1.0 A of power, allowing you to conveniently power various devices (e.g. smartphones), or wireless radio receivers directly from the AS-250. This USB connector is power only, no audio!

The AS-250 can be used as a high quality, plug-and-play compatible USB interface. n Windows Under current windows versions, you need to set the AS-250 as the default playback device manually when connecting it to your computer for the first time. 1. Connect your AS-250 to your computer with the supplied USB cable 2. On the desktop, click on the status bar (at the bottom of the screen, margin right) with a right click on the loudspeaker symbol and then to the „Playback devices“ entry. Alternatively, in the „Control Panel“ go to the entry „Sound.“ 3. A window with available playback devices opens. a) The nuPro speaker appears as “Lautsprecher USB Audio DAC“ on the list b) Click on it and set it as default. c) Click apply to save your settings 4. You can change the name and the icon of your nuPro speaker if you wish. To do so, simply click on the “USB Audio DAC” device, then “properties”. In the window that opens you can change the name and the icon. n MAC OS X 1. Connect your AS-250 to your computer with the supplied USB cable 2. In the system settings, navigate to >Hardware >Sound >output device 3. Select „USB Audio DAC“ USB-connection to a computer

The remote control of the nuPro allows direct access to all common- ly used functions: n on With this key, you toggle the speaker between active and stand-by mode. n volume and mute The volume can be adjusted with the volume keys, the mute key allows you to mute and unmute the speakers. n bass and mid/high The remote control also allows easy adjustment of the sound cha- racter of the AS-250. The mid/high keys are used to raise and lower the bass intensity, while the mid/high keys can be used to adjust the mid/high range by up to ± 12 dB. See the section “Tilt Control” below for more information. n usb · aux · spdif With these keys, you select the source you wish to listen to. USB selects the USB input, aux the analog input. Pressing spdif toggles between the electrical and the optical digital inputs. When handling the remote control: Make sure the battery is inserted correctly, observing the polarity of the battery. If you need to replace the battery, always use a high quality CR2025 battery. Remote Control 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 colour- ations, 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 12 dB at 20 kHz. Autogain After being powered on, the AS-250 sets the input sensitivity au- tomatically. For this reason, it is important that you connect your sources and let them play for few seconds before switching the AS-250 on. If the voltage of the signal increases too much during playback, the input sensitivity is automatically lowered. You can de- activate this function in the menu (see page 9, section “AGAIN”). Digital Signal Processing For maximum fidelity, the signal path of a nuPro loudspeaker is kept entirely digital: Digital input signals go straight to the digital signal processor (DSP), which then performs crossover functions 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 for best possible precision and signal to noise ratio. Latency compensation Due to the digital signal processing, a slight delay is introduced, so-called latency. If you connect additional nuPro loudspeakers to the link-output, this delay is automatically compensated for in order to ensure the best possible time-alignment. The result is an optimal stereo image with precise voice location (see page 9, section “fur- ther use cases”). Sound format The digital inputs of your nuPro loudspeakers accepts PCM-format signals only. 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. Auto-on/off function The auto on/off function reacts differently, depending on the select- ed input: If no signal is present at the analog input, the loudspeaker is switches 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 and Op- tical digital inputs, the presence of the digital data stream is moni- tored, while at the USB input the presence of USB supply voltage is detected. The auto-on 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 Note: Morn computers often have USB sockets that deliver con- stant 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. Remote control signals, AS-250 and the nuPro A-series. The remote-control signals of the AS-250 and the nuPro A-series loudspeakers do not cause interference with each other, making it possible to use combinations of these systems without acci- dentally operating the wrong speaker. (see page 9)

All settings of the AS-250 can be adjusted and read using the key- pad and display on the front of the speaker. After 8 seconds of inac- tivity, the display changes back to its default readout (default: level). Pressing a key will take you to the last used menu or let you adjust the volume. Pressing  in the volume menu will access the main menu. Pressing this key will always take you back to a higher menu level. By pressing  or  you can access the different menus and change their settings. By pressing  you will enter a sub-menu. Pressing the MENU key in the middle will confirm a selection you have made or confirm the choice of a sub-menu. Note: Your settings are saved when the display changes back to its default state. If power to the nuPro speaker is lost before this happens, the speaker will load the last saved state when power is restored. n VOLUME Use the  and  keys to adjust the volume. Note: The displayed level can be set to show either a positive or negative value. Press and hold the central MENU-key to set the display to your preference. Mode A Mode B Maximum Level Vol 80 V 0 dB Minimum Level Vol 0 V-80 dB n INPUT Use the  and  keys to select a source.   AUX IN Analog Line-In   USB IN USB Input   SPDIF Electrical Digital Input   OPTICL Electrical Optical Input n MID HI (Mid/High) Use the  and  keys to raise or lower the mid/high level by up to 12 dB. See also page 7, section “Tilt control”. n BASS Use the  and  keys to raise or lower the bass level by up to 12 dB. n BAL (Balance) Use the  and  keys to change the relative level between the left and right channel by up to 9 dB. n SETUP This menu option is used to select the playback mode. In stereo mode, each of the two channels of the AS-250 receives the corresponding left or right signal of the playback-source. If the mono mode is selected, the DSP generates a mono sum signal and outputs this to both channels equally. The total level is cor- rected in such a way that no volume change occurs. This mode is recommended in combination with further nuPros. See page 9 in the section „Further configurations“. n SUBOUT The subwoofer output outputs a low-passed mono sum signal. In this menu you can set the desired crossover frequency for the sub- woofer. Use the  and  keys to change the crossover frequency. n SYS HP (High-pass and crossover frequency) In this menu, you can set the high-pass (lo-cut) filter frequency. This is particularly useful if you connect a subwoofer to your nuPro speaker. Use the  and  keys to activate (ON) or deactivate (OFF) the filter. If the Filter is set to ON, press  or the MENU key to get to the next menu where you can set the proper frequency, using the  and  keys Note: Setting the high-pass filter to a higher frequency increases the maximum possible sound pressure level from your nuPro loud- speaker. n DISPLY (Display) After 8 seconds of inactivity, the display reverts to its default readout. The DISPLY menu allows you to change this readout. You can set the display to display the level (VOLUME), the nuPro logo (LOGO) or turn the display off (OFF). n LIM DS (displaying limiter/overload protection status) Each nuPro loudspeaker has a built-in, always active protection cir- cuit, which reliably protects the drivers from overload. If the built-in overload protection is active, this is indicated in the display by the word LIMIT. In this menu, you can choose to have this warning-mes- sage displayed (ON) or not (OFF). n PRESET In this menu, you can save all settings of the nuPro speaker in three presets. To do this, select the preset slot you want to save in, us- ing the  and  keys, then press the MENU button until the word SAVING appears in the display. To recall a preset, select it in the menu and confirm with a short press of the central MENU button. LODING is then briefly shown in the display to confirm the selection. n AUTO The electronics of the AS-250 has an automatic stand-by function, which automatically switches the loudspeaker to stand-by and back on as required. Selecting OFF disables this function. Further information on the automatic stand-by function can be found on page 7 in the “ Construction and technology” section. n AGAIN (Autogain) By default, the input sensitivity of your nuPro speaker is set automat- ically to avoid overload and distortion. If you don’t want to use this feature, select OFF in this menu. The input sensitivity is then fixed at 1,5V. See also Page 7, “construction and technology”. n DEFALT In this menu you can reset the speaker to factory settings. To reset your speaker, select OK and confirm by pressing the MENU key. LODING is then briefly shown in the display to confirm the reset. Note: You can also reset the speaker by pressing and holding the  key for 8 seconds. Configuring your nuPro loudspeaker MENU

Further use-cases n Adding a subwoofer If you want to add a subwoofer to your nuPro speaker, you can connect it to the sub out output. This output provides the subwoof- er with a low-pass filtered, summed mono signal. You can set the crossover frequency for the subwoofer in the menu advan-ced / subwoofer.The cut-off frequency for the nuPro speaker is adjusted in the SYS HP menu (see page 8). The relative level of the sub- woofer must be set on the subwoofer itself.

MENU Care and cleaning tips Caution! 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 com- pletely 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 re- moved. 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 pro- tective 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.

Warranty services do not extend the warranty period, nor do they set a new warranty period in motion. The warranty period for installed spare parts ends with the warranty period for the entire device. The promise or the execution of warranty services is made without recognition of a performance obligation according to statutory warranty law. 3. The warranty claim does not apply in the case of • repair attempts of any kind not previously agreed upon with Nubert • improper operating environment or improper storage (e.g. damage due to moisture or particularly high or low temperatures) • improper transport packaging (the original transport packaging, correctly used, provides suffi cient protection) • improper transport, if the transport was not previously agreed upon with Nubert (Nubert organizes the transport for you with Nubert selected Transport company. You will receive return tickets with the corresponding postage paid returns). • improper mechanical effects on the goods (e.g. on housing, switches, connection sockets or antennas) • improper operation, improper mounting (e.g. switches, antennas) or improper connection (e.g. operation on defective or unsuitable amplifi ers or other source devices with DC voltage or unusually high hum voltage at the source device output). 4. Disassembled components Do not disassemble any components from our equipment and do not send in any such individual parts until you have contacted Nubert Service and agreed on this measure. 5.

Shipping information: We recommend that you always keep the original carton, along with the protective foam inserts. Tip: Folding saves space! This is the only way to ensure a safe return shipment in the worst-case scenario. If, in exceptional cases, you use a different packaging, it should protect professionally against the typical dangers of shipping and have special protective cushions or equivalent protective devices. We would like to draw your attention to the fact that we accept no liability for damage caused by improper packaging for which you are responsible! Disposal and battery return Environmental protection: Ingredients, e.g. chemical pollutants in old appliances, can damage the environment and health if stored improperly, in particular if they are not shatterproof or disposed of properly by persons not authorised to do so. Especially in the case of illegal exports, there is no guarantee that the environment and human health will be protected from damage. Old appliances can also contain recyclable raw materials, old appliances can be repaired or parts can be reused and thus considera- bly protect the environment. Old appliances must therefore not be disposed of with normal household waste or exported illegally. As an end user, you are legally obliged to return or properly dispose of electrical equipment. Batteries: Ingredients, e.g. chemical type of batteries, can damage the environment and health if not stored and disposed of properly. At the same time, recyclable raw materials may also be included. Batteries must therefore not be disposed of with normal household waste. As an end user, you are legally obliged to return used batteries. You can return batteries after use to the seller or in the designated collection points (e.g. in public collection points in your municipality or in the trade) free of charge or send them back free of charge. You can also send the batteries back to the seller free of charge by post, whereby any requirements of the dangerous goods law must be observed. The sale at points of sale is limited to the quantities customary for end users for disposal as well as used batteries which the distributor carries or has carried in its product range. • Battery return The symbol with the crossed-out dustbin reminds you not to put batteries in the household waste. Under this symbol you can also fi nd the following symbols with the following meaning about ingredients: Pb = battery contains more than 0.004 mass percent lead, Cd = battery contains more than 0.002 mass percent cadmium, Hg = battery contains more than 0.0005 mass percent mercury. • Old appliances Electrical and electronic equipment is also marked with the crossed-out wheelie bin symbol. The symbol indicates that you, as the owner of this appliance, may not dispose of it with your household waste (grey bin, yellow bin, organic waste bin, paper or glass). You can send the device to the municipal collection points to be collected separately from unsorted municipal waste for reuse. Used batteries and accumulators which are not enclosed by the waste equipment shall be separated from it at a collection point prior to delivery. Old appliances can also be returned to us directly in our shops or shipped back to us for disposal. Please send an Email to [email protected] for a free return shipping label. You can also request this by calling +49 7171-92690118. Please then send the old device to the following address: Nubert electronic GmbH, Goethestr. 69, D-73525 Schwäbisch Gmünd, Germany. Please ensure that the old appliance is properly packaged for shipment so that breakage is avoided as far as possible and mechanical compaction or breakage can be ruled out. The acceptance of waste equipment may be refused if there is a risk to human health and safety due to contamination. Please note: You are responsible for the deletion of personal data on the waste equipment to be disposed of.
