Adjusting the brightness of the Neumann logo
WARNING
Danger of hearing damage due to unexpected high sound pressure levels!
If the Neumann logo is switched o, it is not obvious whether the product is switched on or o. In this case, unex-
pected high sound pressure levels can cause hearing damage.
X
Always set the audio sources connected to the loudspeaker to a low output level before they deliver an audio
signal.
X
If you switch o or dim the Neumann logo, mention this to everyone who works with this loudspeaker or the
connected audio sources.
To dim or switch o the Neumann logo in low light level environments or when the loudspeaker is placed behind an
acoustically transparent screen:
X
Set the DIP switch [1] to:
• “On” to switch on the Neumann logo.
• “O” to switch o the Neumann logo.
X
Set the DIP switch [2] to:
• “Dim” to dim the Neumann logo.
• “Bright” to not dim the Neumann logo.
When the loudspeaker’s protection system is active or invalid digital signals are connected to the KH 120
D, the Neumann logo’s color changes from white to red. The brightness of this red limiter indication can be
adjusted by means of the DIP switch [2] (“Dim” or “Bright”). However, you cannot switch o the limiter indica-
tion, as it appears independent of the position of the DIP switch [1].
