Configuring and using the KH 120
Switching the KH 120 on/off
X
Set the on/off switch to:
• “ON” to switch on the loudspeaker . The Neumann logo lights up, provided that is has not
been switched off (see page 11) .
• “OFF” to switch off the loudspeaker . The Neumann logo goes off .
There is a five second delay before sound can be heard from the loudspeaker in order
to avoid noises (pops) from preceding equipment switched on at the same time . Con-
versely, switching off the loudspeaker immediately mutes the audio .
Adjusting the frequency response
When all its acoustical controls are set to 0 dB, the KH 120 loudspeaker is designed to have
a flat frequency response in anechoic conditions . When the loudspeaker is installed in your
monitoring environment, the response changes . The same loudspeaker installed in different
positions in the same room may require different acoustical control settings . In a symmetrical
installation, left/right pairs (front or back) will probably have the same acoustical settings .
X
Before using your loudspeaker system for the first time, calibrate the frequency response of
the loudspeakers in the room in order to obtain the desired response .
X
Repeat the above step if you change the physical conditions in your studio .
X
At your listening position, determine the frequency response of each loudspeaker .
X
Use the acoustical controls to adjust the frequency response .
Recommended frequency responses:
• Studio applications: flat
• Film applications: X-curve shape (see ANSI/SMPTE 202M)
• Home applications: subjective evaluation
Acoustical control Function Possible settings
Bass Compensates for acoustical loading in

consoles or desks) . 0, - 1 .5, - 3, - 4 .5 dB
Treble Compensates for insufficient or
excessive high-frequency damping in
the room . +1, 0, - 1, - 2 dB
