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 (info@nubert.de)!

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!

Danger of electric shock!
Faulty mains supply systems or excessive mains voltage can lead to electric shocks.

nuBox A-125 · 07/2020
Thank you very much for choosing the nuBox A-125 active loudspeakers.
You will be able to set up your system without any prob-lems if you read these operating instructions carefully. We will explain the operation, connection and installation so that you can achieve the optimum sound quality and fully enjoy your nuBox speakers!

Unpacking and Scope of Delivery

Unpacking
When unpacking your speaker, do not use sharp or pointed objects to avoid possible damage to the enclosure. Please keep the pack-aging 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:

2 nuBox A-125 active loudspeakers (1 active master speaker, 1 passive slave speaker)
2 Cloth grilles
1 Remote control with battery
1 Mains cable, 1.8 m
1 Master-Slave loudspeaker interconnect cable, 3 m
1 Fibre optic cable with TOS-Link plugs, 1.5 m

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 re-stricted. 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 cloth grill removed, the loudspeaker sounds somewhat brighter and clearer – the choice is yours!

Setup

The nuBox A-125 are high-quality, very neutral active stereo loud-speakers. 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 rear-facing bass reflex ports should be at least 3 centimetres away from back- and side walls in order to avoid air flow noise. 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 even 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.
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

Caution! All connections to the A-125 must be made before you connect the loudspeaker to the mains!
The right speaker is the so-called master. All source devices are connected here. The connection to the left loudspeaker (the slave) is made with the supplied loudspeaker cable with four-pin round plug connectors.

Connect the loudspeaker cable
First connect the two speakers to each other. A suitable loudspeaker cable with round plugs is included in the scope of delivery. Longer speaker cables can be purchased as accessories at www.nubert.de

Please note:
Pay attention to the orientation of the connectors in the sockets.

a) The groove on the connector must point to the left.
b) Push the clamping nut forward and fasten it tightly clockwise to prevent the connector from falling out.

Connect the signal cables
Now connect all source devices and (optional) subwoofer to the master loudspeaker. See illustration on page 7 for details.

Connect the power cable
First connect the power cable to the power jack on the back of the master speaker and then to the mains.
The wiring of your speakers is now complete!

Remote control.

The nuBox A-125 speakers can only be operated by the supplied remote control:

on/off
Use the on/off key to activate the A-125 or switch it to standby mode. If the loudspeaker is turned off with the remote control, auto-matic switch-on will be deactivated. (Exception: HDMI input)

volume and mute
The volume can be adjusted with the volume keys .
The mute key allows the A-125 to be muted and unmuted.

input
Press the input key to switch to the next input. Refer to the table above for order and colour assignment of the inputs.

pair
If the Bluetooth input is activated (indicated by the blue status LED on the front panel of the master loudspeaker), pressing this button will initiate the pairing process. Refer to section ‘Bluetooth: Pairing’ on page 9 for details.

music und movie
Pressing the music or movie buttons activates special DSP algo-rithms, resulting in a greater sense of depth and width. Pressing the respective key again deactivates this function. For details, see “Virtual expansion of the stereo stage” on page 9.

When changing the battery

Make sure the polarity of the battery is correct when inserting it into the battery compartment.
Always use high-quality CR2032 lithium button cells as replace-ment batteries.

Operation and Functions

Bluetooth: Pairing
Press the input button on the remote control repeatedly to switch to the BLUETOOTH input (the LED on the front panel lights or blinks blue).

Possible states:

Possible states:

LED lights continuously:              Active Bluetooth connection
LED flashes slowly:                     No active bluetooth connection
LED flashes quickly:                   Bluetooth is in Pairing Mode

Pairing mode can be activated by briefly pressing the pair button on the remote control. The loudspeaker emits a confirmation tone, disconnects the current Bluetooth connection and is visible to other devices. You can now pair with an compatible smartphone, tablet, or computer. If no pairing is performed within one minute, the A-125 returns to the previous operating mode and reconnects to the last device used.

Bluetooth: Volume control
Virtually all devices that output an audio signal via Bluetooth have their own volume control. For the best possible quality it is recom-mended to set the volume of the source device to maximum and adjust the playback volume with the remote control of the nuBox active loudspeaker.

Auto power off
The speakers have an automatic power off function that cannot be deactivated. If one of the inputs Bluetooth or AUX is selected, the loudspeaker switches to standby mode after a maximum of 20 min-utes without audio input.
With the digital inputs COAX, OPTICAL and HDMI the auto-off cir-cuit reacts directly to the absence of a digital data stream and thus allows a faster switch-off. The playback device must deactivate the data stream accordingly.

Auto power on
The electronics of the nuBox active loudspeaker have an automat-ic switch-on function that automatically wakes them from standby mode as soon as a sound signal or a digital data stream is present. This function is only active if the A-125 has been put into standby mode by the automatic switch-off function.

At the HDMI input, the automatic switch-on function is always active.
However, this function is not available for Bluetooth devices.
At the other inputs, Auto Power On is only active if the A-125 is set to standby mode by the Auto Power Off function.
If standby mode has been set manually by pressing the button on/off on the remote control, the automatic switch-on function is deactivated.

HDMI-ARC and CEC
To enable sound transmission from the TV set to the nuBox A-125 master speaker, both the CEC and the ARC functionality must be activated on the TV set. Usually this is the default condition and the TV should automatically detect the speaker. Refer to the TV manual if necessary.
If these functions are active, both the TV and the remote can control the volume of the A-125 stereo set.

PCM sound format
The nuBox active loudspekers process signals in the “PCM” format at the digital inputs. 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 audio output format in the playback menu. Please also refer to the manual of your player.

Factory Default
To reset the speaker to it’s factory settings, turn the speaker on and press the mute key x on the remote control for 3 seconds within the first 5 seconds. The loudspeaker confirms the process with a green LED and switches to standby mode. At the next start, all set-tings are in the factory settings.

Construction and technology

Virtual expansion of the stereo stage
A sophisticated DSP algorithm in the nuBox active loudspeakers cal-culates additional room information which when added to the source signal, leads to a virtual expansion of the stereo stage.There are 2 versions:

If the music function is selected the effect is rather soft.
If the movie function is selected, the ratio of processed informa-tion to the original signal is increased; this mode is recommended especially if a very large soundstage is desired and the locating precision is less important.

Pressing the respective button activates the effect. The LED on the loudspeaker front acknowledges the activation by flashing seven times. If the key is pressed again, the effect is deactivated again. The LED on the loudspeaker front flashes only once to confirm.

Signal processing
The complete active electronics including signalling, control elec-tronics and all amplifiers are located in the right speaker, the so-called master. The two chassis of the left speaker, the so-called slave, are connected by means of a four-pole loudspeaker cable. The nuBox Stereo Set is therefore a fully active system, as each chassis is powered from its own amplifier channel.
The electronic module consequently has four digital amplifiers that receive their signals directly from a high-quality digital signal proces-sor. This processor also works as a crossover network and takes care of the optimization of the frequency response.

Further applications

Operation with a subwoofer
If your nuBox A-125 is to be used in combination with a subwoofer, you can connect it to the SUBOUT output. This output provides a full-range summed mono signal. The relative volume of the subwoof-er, its crossover frequency and phase settings must be adjusted at the subwoofer itself.
If you connect a subwofer to this output, an 80 Hz low-cut is auto-matically applied to the A-125 to ensure proper integration between the A-125 and the subwoofer.

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.

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.
