nuVero 170

Safety Instructions

• Turn off the amplifier before connecting the speaker cables.
• Only place the speaker in a dry location.
• Avoid exposing the speakers to direct sunlight.
• Overload: The nuVero 170 features internal safeguards against amplifier-induced overload. However, even a low-powered amplifier can damage a speaker. At high volumes, weak amplifiers may produce distortions that heavily strain the tweeters. If the sound becomes distorted at any point, please reduce the amplifier's volume.
• Tipping Hazard: Due to its slim design, the nuVero 140 is at risk of tipping over sideways. It should never be used without the included traversing feet.
• Caution: The nuVero 140 can generate maximum levels that may cause permanent hearing damage if listened to for extended periods. The volume level is at your own risk. The Nubert company cannot accept liability for hearing damage caused by excessive volume.

Cold Weather and Sound

When speakers are shipped or delivered during cold weather, they must adapt to room temperature before use. Low temperatures significantly impact the moving parts of a speaker, such as the diaphragm/voice coil, surround, and spider. These components may not perform optimally, affecting sound quality. This is not harmful but prevents the speakers from delivering their best performance.

Tip: If your new speakers arrive on a cold winter day, give them a few hours to acclimate. Your Nubert speakers will reward you with the outstanding sound quality you expect from us.

Warning

The threaded inserts are only for mounting the traversing feet! They are not designed for tensile loads and should not be used for hooks or similar mounts to suspend the speaker.

Setting Up the Speaker

All steps for unpacking and setting up the nuVero 140 are explained in a separate included DIN A3 information sheet.

Due to the weight of the nuVero 140, always handle it with two people! After unpacking the box and attaching the traversing feet, be sure to protect your flooring by placing protective materials like cardboard under the edges of the feet before positioning the speaker!

1. Take one of the cardboard angles from the packaging.
2. Slide it under the lying speaker as shown, so that the traversing foot rests on the cardboard angle.
3. Carefully tilt the speaker upward using the cardboard angle until it stands securely. Then, gently remove the cardboard strips.

Connection Instructions

Please ensure your amplifier/receiver is turned off before connecting the speakers. Refer to the device's user manual for instructions on connecting the speakers to the amplifier/receiver.

Care and Cleaning Tips

Caution!

Improper handling of the speaker may cause damage.

• Turn off your amplifier and, if necessary, disconnect the speaker cables from the terminal before cleaning the speaker!
• Ensure all connections are correct, there are no short circuits, and the speaker is completely dry before resuming operation!
• Do not use harsh cleaning agents or solvents such as gasoline, alcohol, or similar substances!

Cabinet

We recommend using standard glass cleaner sprayed onto a cotton cloth to remove fingerprints and dirt effortlessly. Alternatively, use window active foam. Avoid microfiber cloths, as they may cause micro-scratches on the surface. For veneered cabinets, use suitable furniture care products.

Membranes and Speaker Chassis

To remove dust from a speaker chassis, use a lint-free cotton cloth and gently wipe the diaphragm with very light pressure. The tweeters of all Nubert speakers are equipped with a protective grille, allowing them to be wiped with light pressure as well. If dust cannot be completely removed, a makeup brush from a drugstore may be suitable.

Stands and Traverses

For cleaning stainless steel surfaces, plant gloss spray has proven to be an excellent choice. Rub or polish with a cotton cloth.

Bi-Amping

Caution!

Do not forget to remove the bridges at the connection terminal for Bi-Amping!

Following the principle of separate signal supply for bass/midrange and treble sections leads to Bi-Amping (Bi-Amping = dual amplifiers). This relatively complex method requires a preamplifier to which two stereo power amplifiers can be connected: one for the bass/midrange and the other for the treble section.

Bi-Amping aims to provide more controlled driver operation and better precision. Carefully evaluate the effort and the results before deciding.

An unstable location can damage the device.

• Only place the device 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 device or damaging the connection sockets!
• Keep strong mechanical shocks away from the device!

Caution!

Excessive heat build-up inside the unit can shorten its service life or lead to fire.

• Never cover the device! Make sure that there is a clearance of at least 10 cm and sufficient air circulation around the device!
• Do not operate the device and remote control near heat sources such as radiators or stoves!
• Do not expose the device and remote control to direct sunlight.
• Never place burning candles or similar open fire sources on the device!

Danger of Explosion!

Installation in unsuitable locations can cause explosions. Do not use the device 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 vapors!
• near strong dust!
• near flammable materials!

Danger of Electric Shock!

The device 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 device with wet hands!
• Only use the device in a dry place!
• Do not operate it outdoors or in damp rooms!
• The device 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 device or in the immediate vicinity!
• If the device is moved from a cold environment to a warm room, condensation may form inside the unit. Wait at least six hours until the device has reached room temperature and is dry before switching it on!
• No objects of any kind may get into the device.
• Should the device come into contact with liquids or should objects have gotten inside, please unplug the mains plug immediately and contact Nubert electronic GmbH (info@nubert.de)!

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 device 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 device, 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.
