nuLine 34

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.
• Ensure stable mounting when using stands or wall mounts.
• Overloading: The nuLine 34 features internal fuses to protect against amplifier overload. At high volumes, weak amplifiers can cause distortion that places extreme stress on the tweeters. Reduce the amplifier's volume if the sound becomes distorted.

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.

Bi-Amping

Caution!

Do not forget to remove the bridges on the connection terminal! In bi-amping, bass/midrange and treble areas are supplied with separate signals. This setup requires a preamplifier and two stereo power amplifiers: one for the bass/midrange and one for the treble range. Bi-amping can result in better driver control and improved precision. However, the effort and results should be carefully considered.

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 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 Nubert speakers are protected by a grille and can also be gently wiped clean. For stubborn dust, a makeup brush can be used.

• Avoid being near the unit during a disaster, such as an earthquake. Since the unit may turn over or fall and cause injury, quickly move away from the unit and go to a safe place.
• Before moving this unit, be sure to turn off the power switch and disconnect all connection cables. Failure to observe this may damage the cables or cause you or someone else to trip and fall.
• For proper installation of an outdoor antenna, make sure it is done by the dealer from where you purchased the unit or by qualified service personnel. Failure to observe this may cause the installation to fall and result in injury. Installation requires special skills and experience.

Hearing Loss

• Do not use the unit for a long period of time at a high or uncomfortable volume level, as this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician.
• Before connecting the unit to other devices, turn off the power for all devices. Also, before turning the power of all devices on or off, make sure that all volume levels are set to the minimum. Failing to do so may result in hearing loss, electric shock, or device damage.
• When turning on the AC power in your audio system, always turn on the unit LAST, to avoid hearing loss and speaker damage. When turning the power off, the unit should be turned off FIRST for the same reason. Failure to observe the above may cause hearing impairment or speaker damage.

Maintenance

Handling Caution

• Do not touch the surface with a warning label. This surface may become hot during operation and cause burns.
• Do not insert foreign materials such as metal or paper into the openings of this unit. Failure to observe this may cause a fire, electric shocks, or malfunctions.
• Keep small parts out of the reach of infants. Children may accidentally swallow them.
• Avoid the following actions:
  • Standing or sitting on the equipment.
  • Placing heavy items on top of the equipment.
  • Stacking the equipment.
  • Applying unreasonable force to buttons, switches, or input/output terminals.
  Failure to observe this may cause injuries or damage to the equipment.
