Configuring and using the KH 120
Switching the KH 120 on/off
X
Set the on/o switch to:
• “ON” to switch on the loudspeaker. The Neumann logo lights up, provided that is has not
been switched o (see page 16).
• “OFF” to switch o the loudspeaker. The Neumann logo goes o.
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 o 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 dierent
positions in the same room may require dierent 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.
