Why are my Neumann.Berlin Speakers buzzing?
- H
  Howard HernandezAug 7, 2025
  If your Neumann.Berlin Speakers are buzzing, it could be due to incorrect wiring or poor grounding in the audio cable. First, inspect the cabling, particularly if you're using unbalanced cables. Refer to the cable wiring diagram. Try using gold-plated connectors. Lower the loudspeaker's output level while maximizing the audio source's output level (without clipping). Finally, set the GROUND LIFT switch to the Lift position.

Why do my Neumann.Berlin Speakers sound thin?
- C
  Christina NelsonAug 19, 2025
  If your Neumann.Berlin Speakers sound 'thin' in the bass, it could be due to incorrect wiring in the audio cable or adapter, or one loudspeaker might be out of phase with the other, causing cancellation in the low frequencies. Check the cabling, especially if unbalanced cabling is in use. Also, verify the settings on your signal source.

What to do if Neumann.Berlin Speakers have no sound and the logo is off?
- A
  Amber NelsonAug 31, 2025
  If the Neumann logo is off and no sound is coming from your Neumann.Berlin Speakers, the loudspeaker’s main internal fuse may have blown. Have the product checked by an authorized Neumann service partner, as there is no plug fuse in the device.
