Confi guring and using the KH 120
Switching the KH 120 on/off
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 fi ve 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 fl at frequency response in anechoic conditions. When the loudspeaker is installed in your
monitoring environment, the response changes. The same loudspeaker installed in diff erent
positions in the same room may require diff erent acoustical control settings. In a symmetrical
installation, left/right pairs (front or back) will probably have the same acoustical settings.
Before using your loudspeaker system for the fi rst time, calibrate the frequency response of
the loudspeakers in the room in order to obtain the desired response.
Repeat the above step if you change the physical conditions in your studio.
At your listening position, determine the frequency response of each loudspeaker.
Use the acoustical controls to adjust the frequency response.
Recommended frequency responses:
• Studio applications: fl at
• Film applications: X-curve shape (see ANSI/SMPTE 202M)
• Home applications: subjective evaluation
Acoustical control Function
Bass Compensates for acoustical loading in
the low frequency range due to nearby
large solid boundaries (e.g. walls).
Low-Mid Compensates for acoustical loading
in the low-mid frequency range due
to nearby large solid objects
(e.g. mixing consoles or desks).
Treble Compensates for insuffi cient or
excessive high-frequency
damping in the room.
Possible settings
0, −2.5, −5, −7.5 dB
0, −1.5, −3, −4.5 dB
+1, 0, −1, −2 dB
