Adjusting the acoustic level

On your KH 120 loudspeakers, set the output level control ("OUTPUT LEVEL") to 94 dB SPL
and the input gain control ("INPUT GAIN") to −15 dB.
Play a broadband pink noise test signal that is set to −18 dBFS (Europe) or −20 dBFS (USA)
on the mixing console' output level meters.
Measure the sound pressure level at the listening position using a sound level meter with
the following settings:
• "C"-weighted
• slow integration time
Set the output level and input gain controls of your loudspeakers so that the desired acous-
tic level is obtained.
Recommended sound pressure levels:
Application Sound pressure level
Film 85 dB(C)
Broadcast 79 to 83 dB(C)
Music No defi ned reference levels
If the Neumann logo fl ashes red, the loudspeakers' protection system has been activated.
To avoid this and achieve the desired output level, use larger loudspeakers or add a bass man-
aged subwoofer to the system.
