nuLine 264

Safety Instructions

• Turn off the amplifier before connecting the speaker cables.
• Ensure the speaker cables are securely connected.
• Place the speakers only in a dry location.
• Do not expose the speakers to direct sunlight.
• Overloading: The nuLine 264 features internal fuses to protect against amplifier overload. However, note that even a weak amplifier can endanger a speaker. At high volumes, weak amplifiers tend to distort, which places extreme stress on the tweeters. If the sound becomes distorted at a certain volume level, reduce the amplifier's volume setting.
• Tipping Hazard: Due to its slim design, the nuLine 264 is at risk of tipping sideways. It should never be used without the supplied traverse feet.

Cold Weather and Sound

If speakers are shipped and delivered during the cold season, they must acclimate to room temperature. Low temperatures significantly affect the moving parts of a speaker box, such as the diaphragm/voice coil, surround, and spider. These components' ability to follow rapid vibrations or make large excursions is severely limited. While not dangerous, “deep-frozen” speakers will not perform at their best acoustically. Our advice: 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 rightly expect from us.

Caution!

The threaded sockets are for mounting the traverse feet only! They are not designed for tensile loads and must not be used to attach hooks or similar devices for hanging the speakers.

Connection Instructions

Ensure that your amplifier/receiver is turned off before connecting the speakers. Refer to your amplifier/receiver's user manual for specific connection instructions.

Care and Cleaning Tips

Caution!

Improper handling of the speaker may result in damage.

• Turn off your amplifier before cleaning the speaker and disconnect the speaker cables from the terminal if necessary.
• Before resuming operation, ensure that all connections are correct, no short circuits exist, and the speaker is completely dry.
• Never use harsh cleaning agents or solvents such as gasoline, alcohol, or similar substances.

Cabinet

We recommend using a standard glass cleaner sprayed onto a cotton cloth for cleaning. This will effectively remove most fingerprints and dirt. Alternatively, you can use window cleaning foam. Avoid using microfiber cloths as they may cause micro-scratches. For veneered cabinets, we recommend using appropriate furniture care products.

Membranes and Speaker Drivers

Use a lint-free cotton cloth with gentle pressure to remove dust from the speaker driver. The tweeters in all Nubert speakers are protected by a grille and can also be gently wiped clean. For stubborn dust, a makeup brush from a drugstore can be used.

Cold Weather and Sound Quality

If speakers are shipped and delivered during cold weather, they must acclimate to room temperature before use. Low temperatures significantly affect the moving parts of a speaker, such as the diaphragm/voice coil, surround, and spider. These components' ability to handle fast vibrations or large excursions becomes limited. While not harmful, "frozen" speakers will not perform at their best acoustically.

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